Psychiatric illness and dentistry: Challenges for oral care

David Clark

Ontario Shores Centre for Mental Health Sciences, Canada

Psychiatric illness and its medical management carry significant risks for oral disease. Although mental illness is common, in many cases it is misunderstood, remains unrecognized, or is undertreated. Mental illness and the resulting disabilities create difficulties not only for the patient but also for oneʼs family and friends, not the least of which remains the highly stigmatized nature of the disease itself.

Understanding the type, severity, stage of mental illness, along with a patientʼs own mood, motivation and personal perceptions of oral disease and lifestyle can enhance the knowledge of dental professionals concerning this critical aspect of a patientʼs medical history and further illustrates how closely mental health and oral health are intertwined.

Mental illness must be viewed from a similar perspective as are other major diseases. Dental professionals should be aware of factors such as the reduced rates of compliance with dental treatment, reduced ability to access oral health care, the effects of various psychotropic medications on oral health including xerostomia, caries and periodontal disease and the potential interactions with drugs used in dental practice.

Patients with psychiatric illness often bring unique needs and differing priorities to a dental practice, and the dental health practitioner must in turn demonstrate patience, flexibility, empathy, and a non-stigmatizing attitude in caring for these individuals. Enhancing self-esteem and feelings of self-worth for those coping with a psychiatric illness can be a very fulfilling experience that can only serve to continue to break down the stigma surrounding this group of diseases.

Ameloblastoma of the jaws remains the top difficult to treat odontogenic tumour and has a high recurrence rate. New evidence suggests that non-coding RNAs (ncRNAs) play a critical role in tumourgenesis and prognosis of cancer. However, ameloblastoma ncRNA expression data is lacking. Here we present the first report of ameloblastoma ncRNA signatures. A total of 95 ameloblastoma cases and a global array transcriptome technology covering >285.000 full-length transcripts were used in this two-step analysis. The analysis first identified in a test cohort 31 upregulated ameloblastoma-associated ncRNAs accompanied by signalling pathways of cancer, spliceosome, mRNA surveillance and Wnt. Further validation in an independent cohort points out the long non-coding (lncRNAs) and small nucleolar RNA (snoRNAs): LINC340, SNORD116-25, SNORA11, SNORA21, and SNORA65 as a distinct ncRNA signature of ameloblastoma. Importantly, the presence of these ncRNAs was independent of BRAF-V600E and SMO-L412F mutations, histology type or tumour location, but was positively correlated with the tumour size. Taken together, this study shows a systematic investigation of ncRNA expression of ameloblastoma, and illuminates new diagnostic and therapeutic targets for this invasive odontogenic tumour.

Molecular identification of Enterococcus Faecalis associated with primary endodontic infections in Bangalore population and to evaluate the efficacy of common antibiotics against E. Faecalis

Madhu K S Ramaiah University of Applied Sciences, India

Introduction: Endodontic therapy aims at eliminating the existing infection and also inhibiting re-infection. In spite of the standard treatment protocol followed, persistence of microorganism attributes to almost 30% of endodontic failure. Enterococcus faecalis is a commonly detected microorganism (range of 2.4 to 17.7%) in asymptomatic endodontic infections. For effective treatment strategies and outcome, identification and characterization of pathogens is imperative. The objectives were (i) to identify Enterococci genusfrom root canal infections in Bangalore Urban population (ii) to isolate E. faecalis by DNA isolation and gel electrophoresis (iii) to evaluate the antibiotic sensitivity of E. faecalis isolates to routine nine antibiotics.

Methodology: 50 patients with primary endodontic infection were randomly selected for the study. Following ethical clearance and patient consent, isolation and standard disinfection of concerned tooth. After gaining access, root canal was filed to disrupt the biofilm using 15k file. The samples were collected with charcoaled paper point and transferred to Amieʼs transport medium for microbial analysis. To identify Enterococci, the samples along with two standards (ATCC 29212 and MTCC 3159) were subjected to series of standard biochemical (gram staining, salt tolerance and bile esculin hydrolysis) and fermentation tests. The isolates were then subjected to DNA isolation and gel electrophoresis to identify E. faecalis. The antibiotic sensitivity of isolates were assessed against nine antibiotics by Zone of inhibition using a Hi Media scale. The transformed values by Fischerʼs method were statistically analyzed using AGRISTAT (version 6) software.

Results: 16 out of 51 samples (31 %) was identified as Enterococci. Only two samples belong to Enterococcus faecalis registering 3.97 % incidence. The gel electrophoresis of isolated DNA indicated genetical variance of one isolate.

All strains of E. faecalis exhibited identical sensitivity to the antibiotics evaluated revealing their similar genetic makeup. Samples showed intermediate sensitivity to Doxycycline hydrochloride except one. Gentamycin was effective in inhibiting the growth of all cultures. Linezolid exhibited resistance to the isolates.

Conclusion: With the limited literature on E. faecalis in Indian population using molecular technique, the present research findings was one of the earliest of its kind. E. faecalis was found in 3.97% of primary endodontic infections whereas enterococci showed incidence of 31%. The identification and characterization of pathogens is significant as they can cause failure of endodontic therapy as well severe systemic implications. Future line of research envisages for Nucleic Acid-based Research and Metagenomic studies of pathogens for effective treatment strategies.

This prospective single cohort study was conducted to evaluate the efficacy of a composite graft containing rhPDGF-BB+β-TCP (β-tricalcium phosphate) admixed with Xenograft, in the minimally invasive direct sinus augmentation of localised atrophic maxillary posterior ridges. Radiographic (CBCT scan) examinations were done at baseline, immediate post-operative and 6 months post-operatively and histomorphometry was performed 6 months post-operatively. A total of 17 patients (20 maxillary sinuses) with atrophic maxillary posterior residual ridges willing for the implant supported restorations were selected for this study, using consecutive sampling technique, from the out-patient Department of Periodontics, Bapuji Dental College & Hospital, Davangere (India). Surgical procedure was carried under strict asepsis incorporating stress reduction protocol. Direct sinus augmentation procedure was done under local anaesthesia where the lateral window was separated from underlying schneiderian membrane using the wall-off technique. A composite graft containing rhPDGF-BB+β-TCP admixed with deproteinzed bovine bone was used to augment the sub-antral compartment and the bony window was replaced back followed by a resorbable collagen membrane placement. Primary flap closure was achieved using polyamide sutures. An immediate post-operative CBCT was taken to ensure the intactness of schneiderian membrane. After 6-month healing period, a CBCT scan was taken and radiographic evaluation of healed grafted sinus. During the implant placement, a bone core was harvested one per treated sinus from the previous access window and histomorphometric analysis was done. On radiographic evaluation, the mean pre-operative bone height (H0) was 3.02±1.35mm, Post-graft bone height (H1) immediately after the augmentation was 15.18±2.52mm and post-operative bone height (H2) after 6 months observation period was 14.79±2.30mm. The immediate post-graft volume (V1) was 1106.10±398.84 mm3 and post-operative volume (V2) was 1086.95±396.86 mm3. There was significant gain in the residual ridge height over 6 months from the baseline, while there was no significant change in the gained height or volume of the grafted sinus during this period. Histological evaluation revealed the bone bridging and bone regenerative efficacy of the graft material with vital new bone formation, residual graft and non-mineralized tissue of 19.17±2.63%, 33.02±7.01% and 47.38±6.72% respectively and the implants placed in the augmented showed 100% survival rates. The preliminary data obtained from this study, with in its limitations, indicates that this minimally invasive sinus augmentation with the composite graft could be efficiently used for the implant site preparation of posterior maxillary atrophic ridges. A predictable and promising bone gain and integration of the implant was observed with this procedure.

Kareimh Hadhiah and Faisal Fahami

King Saud University, Saudi Arabia

Introduction: The adhesion between the reline material and the denture base to form durable bond is needed for the comfort and function of the patientsʼ prosthesis. Some authors recommend denture surface treatment prior to applying the reline material to overcome the problem of separation of relining materials.

Objectives: The aim of the study was to evaluate the effect two different surface treatments on the tensile bond strength of three different resilient relining materials bonded to urethane dimethacrylate (UDMA) light activated resin denture base and to detect the mode of debonding between the resilient lining materials and the UDMA.

Materials and Methods: A total of 108 dumbbell-shaped specimens UDMA resin specimens were prepared. Specimens were divided into three group. The first group was the control with untreated surface. The second group was treated with Al2O3 size 50μm while the third group was treated with acetone for 30 seconds. Furthermore, these group were divided to three subgroup according to relining materials used, heat-polymerized acrylic (Vertex Soft), self-polymerized acrylic (Perma Soft) and self-polymerized silicone (Bosworth-Dentusil). All specimens were subjected to thermo cycling (1500) cycles for 24 hours, the temperature ranging from5_55°. Then specimens were attachedto instron by a custom jig and subjected to a tensile force at a crosshead speed of 5 mm/ min until debonding occurred. The data was analyzed statistically by Two-way ANOVA and one way ANOVA test for detection of the difference within the group and between the groups.

Results: Two-way ANOVA showed that the surface treatment and the different relining material had significant effect on the tensile bond strength. Perma Soft had the higher tensile bond strength than the other groups (2.465 ±0.261 Mpa) and it was increased 30% more with acetone surface treatment. Sand blasting surface treatment increased the tensile bond strength for Bosworth-Dentusil and vertex soft but not statistically significant. Bosworth-Dentusildebonded in adhesive, cohesive and mixed failure mode. The other two materials debonded adhesively only.

Conclusion: this study showed that Perma Soft relining material is best option for relining UDMA denture resin, and its tensile bond strength was increased 30% more with acetone surface treatment. Each relining material react in different manner than the other for each surface treatment.

Background and Objectives: The microbial profile of aggressive periodontitis patients is considered to be complex with variations among populations in different geographical areas. The aim of this study was to determine the prevalence of four putative periodontopathic bacteria (Aggregatibacteractinomycetemcomitans, Porphyromonasgingivalis, Tannerella forsythia, Treponemadenticola) and two periodontal herpes viruses [Epstein-Barr virus-1 (EBV), human cytomegalovirus (HMCV)] in subgingival plaque and whole saliva of Sudanese subjects with aggressive periodontitis and their family members and to compare the results with those of healthy controls.

Material and Methods: The study group consisted of 122 subjects, 17 aggressive periodontitis patients, 17 periodontally healthy controls (14-19 years of age), 54 family members of the cases and 34 family members of the controls. Whole stimulated saliva and pooled subgingival plaque were collected and analyzed for detection of bacteria and viruses using loop mediated isothermal amplification (LAMP).

Results: Prevalence of subgingival A. actinomycetemcomitans, HCMVand P. gingivalis were significantly higher among aggressive periodontitis patients than periodontally healthy controls. Co-infection with A. actinomycetemcomitans, HCMV and/or EBV-1 was restricted to the cases and their family members. Pooled subgingival plaque showed significant higher prevalence of A. actinomycetemcomitans and P. gingivalisthan whole stimulated saliva in this population (p=0.0001, p=0.04). Increased risk of aggressive peritonitis was the highest when A. actinomycetemcomitans& was detected together with EBV-1(OD 49.0, 95% CI2.5-948.7, p= 0.01) and HCMV(OD 39.1, 95% CI 2.0 - 754.6, p= 0.02).

Conclusions: In Sudanese patients, A. actinomycetemcomitansand HCMV were the most associated test pathogens with aggressive periodontitis. Saliva may be useful as an alternative sampling tool for selected pathogens. However, parallel subgingival sampling is recommended for A. actinomycetemcomitansand P. gingivalis.

Periodontal regeneration: Where do we stand now?

Manoj Humagain

Kathmandu University School of Medical Sciences, Nepal

Complete regeneration of the periodontium remains an elusive goal with current treatment modalities. A number of emerging technologies are being examined that can improve the outcome of periodontal regeneration. These include the application of protein and peptide therapy, cell-based therapy, genetic therapy, application of scaffolds, bone anabolics, and lasers. As emerging technologies, by definition, most of these therapies lack high levels of evidence. Currently, there are numerous human clinical trials in varying stages of completion that are attempting to delineate the best applications of the emerging therapies.

Emerging technologies are presenting options to hopefully improve the outcomes of regeneration in challenging clinical scenarios. Cellular allografts represent a current technology in which cells and scaffolds are being delivered directly to the periodontal lesion. Recombinant human fibroblast growth factor 2 and teriparatide (parathyroid 1-34) have each been tested in controlled prospective human randomized clinical trials, and both have been shown to have potential for periodontal regeneration. These examples, as well as other emerging technologies, show promise for continued advancement in the field of periodontal regenerative therapy.

At present, there are indications that emerging technologies can be used successfully for periodontal regeneration. Case reports and clinical trials are being conducted with a variety of emerging technologies. However, many are yet to be approved by a regulatory agency, or there is a lack of evidence-based literature to validate their expanded use. This presentation will review the existing modalities of the periodontal regeneration and its future perspective.

Shear bond strength of a bracket-bonding system cured with a light emitting diode or halogen based light curing unit at various polymerization times

Sanjay Prasad Gupta and Basanta Kumar Shrestha

Institute of Medicine, Nepal

Objective: The aim was to determine and compare the shear bond strength of bracket-bonding system cured with Light emitting diode and Halogen based light curing unit at various polymerization times.

Methods: Ninety six human maxillary premolar teeth extracted for orthodontic purpose were divided into four groups, according to the light-curing unit and exposure times used. In the Halogen group, the specimens were light cured for 20 and 40 seconds. In the LED group, the specimens were light cured for 5 and 10 seconds. Stainless steel brackets were bonded and stored in distilled water at 37°C for 24 hours and then submitted to SBS testing.

Results: The highest mean SBS was obtained with the Halogen 40 seconds (18.27MPa) followed by Halogen 20 seconds (15.36 MPa), LED 10 seconds (14.60 MPa) and least with LED 5 seconds (12.49 MPa) group. According to analysis of variance and Tukey multiple comparison test, Shear bond strength of Halogen 20 seconds group was not significantly different from other groups. LED 5 seconds group was not significantly different from LED 10 seconds group. Whereas Halogen 40 seconds group was significantly different from LED 5 seconds & LED 10 seconds group.

Conclusion: Polymerization with both Halogen and LED resulted in shear bond strength values which were clinically acceptable for orthodontic treatment in all groups. Hence, for bonding orthodontic brackets, photoactivation with Halogen for 20 seconds and LED for 5 seconds is suggested.

Keywords: Shear bond strength, Halogen curing light, LED curing light, Polymerization time

Toothaches of non odontogenic origin

Ivonne A. Hernández

University of Alberta, Canada

A toothache of non-odontogenic origin is pain felt in a tooth with no clinical indication of pulpal or periodontal involvement. From the total dental visits with a chief complaint of a toothache, 3% are of a non-odontogenic origin and 9% are a mix of odontogenic and non-odontogenic origin (Yatani et al 2014).

Non-odontogenic toothaches may represent a wide variety of pain types: neuropathic pain such as trigeminal neuralgia, neurovascular conditions like migraine headaches, visceral pain such as sinusitis and/or a musculoskeletal pain such as myofascial pain. Case reports of headaches mimicking toothache have also been published. However, toothache of non-odontogenic origin may also be due to a more life threatening disease like cancer and/or a heart attack. Incorrect diagnosis of these conditions usually leads to unnecessary dental procedures: root canal therapy and/or dental extractions. The end result is a patient experiencing no change or an aggravation of the pre - existent toothache. In some cases, due to the extensive attempts to palliate the pain, the patient ends with complications including pain in a larger area.

At the end of this presentation, the attendee should be able to learn the main clinical features of a toothache of non-odontogenic origin, and how this pain can be mistaken as a true toothache. Clinical cases of mistaken toothache of odontogenic and non-odontogenic origin will be presented. Differential diagnoses for each case will be discussed. Treatment recommendations and the need of referral to other healthcare professionals will also be outlined.

King Saud University, Saudi Arabia

Objectives: The aim of this study is to evaluate the color changes and surface roughness (Ra) of different types of composite after their immersion in different sport drink types for 7days, 1 month, 3 months as well as 6 months.

Materials and Methods: Sixty specimens were made from different composites (Filtek Z250, Vertis Flow and Spectrum). Each specimen was cured for 20 sec. Color measurements of each specimen were performed with Color Eye system at baseline and at 7days, 1, 3 and 6 months of immersion in the sport energy drinks (Code Red, Red Bull and Bison). Another Thirty six disc-shaped specimens for surface roughness (Ra) determination using a noncontact 3D-optical-profilometer. Baseline and after immersion in the sport drinks for 6 months were determined. Surface topography (Ra) and color changes (DE values) of the groups were recorded and statistically analyzed.

Results: Variations in the composition of different sport drinks media did not affect the color changes of composite groups. The effect of time showed that the color changes of all composite tested are directly proportional to the increase in time. Surface roughness (Ra) showed insignificant difference between the groups except for the Spectrum when immersed in code red the Ra increased.

Conclusion:1. All resin composite tested showed color changes when immersed in sport drinks solutions. 2. The color changes is directly proportional to the time of immersion of resin composite. 3. Vertise Flow showed the least color changes by time followed by the Filtek Z250 while the Spectrum showed the highest color changes.

The aim of this study was to investigate the caries prevalence of 3-5 year old children, attending private school in Dubai. Caries were recorded according to the clinical criteria set by WHO in 1987. Sample size at the age of 3, 4 and 5 was 273, 1205 and 1479 children where the mean dmft values found were 0.90 (2.18), 1.50 (2.73) and 1.72 (2.85) accordingly. The dmft for the total of the sample was 1.55. This is the first caries prevalence study in Dubai recording caries for 3 and 4 year-old children.

Introduction: Dental caries is a multi-factorial infectious disease, which can affect children and adults at any age. Progress of dental caries is faster in primary dentition, as a result of the thinner dental structures both enamel and dentine, along with deferences in mineralization of the primary teeth. Until now there is no data on caries prevalence in 3 and 4 year old children in Dubai and the last available data for 5 year old children date more than a decade ago. Many countries have showed a decline in the dmft values over the years.

Materials & Methods: The sample consisted of 2957 children, (1527 males and 1430 females), 3-5 year-old, attending private schools in Dubai, participated in this study.

Children were screened for caries by three licensed, calibrated dentists using the WHO 1987, clinical examination criteria.

Results: Mean dmft for 3, 4 and 5 year-old children was 0.90 (2.18), 1.50 (2.73) and 1.72 (2.85) respectively.

Conclusions: 3-5 yo preschoolers of Dubai schools exhibited high prevalence of caries with dmft from 0.90 to 1.72

Dentistry and its Industry, a unique profession that is considered & thought of by many as a negative nightmarish force that they have to deal with someday in life, just like a thorn in every rose waiting to be touched. A mandatory fear they will face one day. The repelling attitude expressed by clients & patients is very well established in almost all communities. In movies we are the jock & in real life we are the devil that they are compelled to befriend yet, after pain subsiding or concluding a Smile Make-Over (SMO) we as Dentists all of a sudden become their savior & their best friend!!

Clinical effects of intra-oral photobiomodulation on the rate of tooth movement and pain perception during the alignment phase of orthodontic treatment

Nour Alokla

Dubai Health Care City, UAE

Orthodontic treatment is a long procedure which requires about 18-24 months of treatment. This long duration of treatment can cause a variety of side effects like alveolar bone resorption, root resorption, caries and decrease in the compliance of the patient.

Therefore finding a method to shorten the treatment period remains one of the big challenges lying ahead of orthodontics. Nowadays, the versatility of low-level laser therapy has been extensively applied in clinical practice. In particular, in the field of orthodontics; it has been used for the alleviation of orthodontic pain and acceleration of orthodontic tooth movement. The purpose of this study was to investigate whether the use of photobiomodulation therapy (using OrthoPulse machine from Biolux) combined with conventional fixed orthodontic appliance will result in reducing overall treatment time by accelerating maxillary and mandibular anterior alignment rates and reducing patient pain perception scores during the treatment.

Nour Alokla completed Diploma in dental laboratory technology as Dental technician from Damascus University in 2006, after that She studied Dentistry at Al Kalamoon University in Syria and graduated in 2011. She obtained my Master degree in orthodontic and dentofacial orthopedic from European University college.

Occlusal interferences and temporomandibular joint disorders, diagnostics and treatment

Firas Hamzeh

The Dental Studio, Hollywood Smile Clinic, UAE

In diagnosing patients with possible TMD it is necessary to aknowledge the great variety of causes of orofacial pain and dysfunction. The treatment of the temporomandibular joint disorders can vary from simple self – care techniques to complex multidisciplinary procedures including the splint therapy which is one of the first stops in TMJ disorder treatment. It is very important to have an idea about the functional anatomy of the TMJ, understand the musculo-skeletal stable position of the condyle in the fossa, The understanding of the CPI and the interpretation of the CO/ CR discrepancy after mounting on the articulator, and the map of pain of ROCABADO, in addition to these diagnostic tools we need to understand the radiological diagnosis of the TMJ, the different stages of degenerative joint disease and disc pathology progression. The good understanding of the TMJ and the relations between the seated condyle and the stable occlusion lead us to the right way to treat TMD patients with occlusal interferences. In this lecture weʼll discuss the diagnostic tools that we use in TMD cases, occlusal analysis and treatment options that affect the occlusion and maintain the condyle in a musculo -skeletal stable position with the use of the centric splints and the importance to use the distraction splints with the help of the physiotherapy

Orthodontic correction of a severe high-angle Cl II with gummy smile in an adolescent with Crohnʼs disease

Nadine El Hajj Yaacoub

Orthodontist, UAE

The orthodontic treatment of a 16 years old patient with Crohnʼs Disease (CD) is reported. The patient was diagnosed since the age of 10 years with CD and was undergoing therapy with immunosuppressant agents. She had a severe high-angle skeletal Cl II with gummy smile and a retruded profile. Treatment with 2 posterior and 2 anterior mini-screws with 4 premolar extractions was conducted. Oral breakouts of the disease were triggered by the orthodontic treatment that had to be progressively molded to fit the patientʼs health conditions. A counter-clockwise rotation of the mandible and enhancement of patientʼs profile were achieved. Gummy smile was fully corrected. The interactions of the therapy with immunosuppressant agents, and oral breakouts of CD with treatment progress, results and duration are discussed.

MIMI-Flapless: Minimally invasive is the future in implant procedures

Armin Nedjat

Champions-Implants GmbH, Germany

Autologous bone grafting, biomaterials, invasive techniques, lengthy procedures, etc. are often necessary when traditional implants are selected to reach the therapeutic goal. In Europe, beginning in 1995, Armin Nedjat and Ernst Fuchs-Schaller developed an innovative, minimally invasive surgical approach based on ‘Bioactive Containerʼ which supports the ‘Power of the Natureʼ also in narrow and atrophic jaws. The results of a study of 550 patients operated on between 1995 and 2015 reveal the validity, the long-term safety, and the excellent cosmetic outcome obtained with this MIMI-Flapless I - V protocols, which is also applicable when bone grafting has failed or has proven insufficient. Minimally invasive procedures without mucoperiostal flaps are the future in our daily work in the clinics!

Armin Nedjat, German, obtained his DDS (1993) in Frankfurt/ Main, Specialized in Esthetic Dentistry 1997 Certificate of specialization in Implantologie DGZI (1999), Certificate of specialization in Implantologie ICOI as a ‘Diplomateʼ (2000) and PhD in Dental Surgeryin several universities worldwide. He has been in private practice of Implantologie and prosthodontics since 1994 with more than 23.000 implants in Flonheim/ Frankfurt. He worked as well in Paris, Boston, San Antonio/ Texas, Palma/ Mallorca. Currently, since 2013, he is the Scientific Chairman and first president of the VIP-ZM (Association of innovative practicing dentists in Germany). His main topic is the MIMI-Flapless procedure in Implantologie: This “Key-whole”-surgery without flaps also in narrow bones won the ‘Best Innovation in Medicineʼ in Dubai 2013. He is the founder and CEO of Champions-Implants GmbH, one of the largest implant systems in Germany/Austria. He is anactive member of the DGZI, DGI, BDIZ, DGOI, ICOI, DGL, and DGP. He holds several patents, in particular for materials and instruments for the MIMI-Flapless procedures.

Gold, Porcelain and composite: Which one to chose, esthetic or functional durability?

Huda Masoud and Urs Kuhne

European University College, Germany

Scientific Paper discuss the differences ‘in function and aesthetic prospectiveʼ between three restorative materials “Composite, Gold, Ceramic” and the parameters of selection.

Which on of the three Materials serve as a best filling material based upon there properties ? which one of them is the best aesthetically and functionally in dental practice. what are the factors that affect the selection of restorative material ?

Results: Composite fillings are strong, but may not be as hard wearing as amalgam fillings. Gold inlay and onlay can be used in most areas of the mouth. Gold is the most long-lasting it does not tarnish and has great strength. one disadvantage of Gold restorative Material is that, is made in a laboratory, an impassion of the prepared one which make it uncomfortable choice for most patients, as well as its expense.

Porcelain inlays with the help of digital technology (called CADCAM) which can be used to design and prepare perfectly fitted porcelain inlays in just one or two visits. Porcelain can be hard wearing and long lasting with superior colour matching to tooth which making it quite expensive.

Conclusion: We have come a long way in dentistry with different materials that have been offered to patients, from amalgam, which is not used anymore to Gold, to Resin-based filling materials and laser cavity preparation and one visit Onlay and inlay!

The selection of an appropriate restorative material depends on the case selection. several parameters must be taken in consideration, like “aesthetic, function durability, and skills of practitioner, as well as the financial ability of the patient”.

Is oral health deteriorating? Results from epidemiological studies in Sweden 1983-2013

Kristina Edman, Kerstin Öhrn, Birgitta Nordström and Anders Holmlund

Uppsala University, Sweden

Aim: The aim of this studies was to investigate the prevalence of alveolar bone loss (ABL), manifest caries and the influence of socioeconomic factors and smoking using data from four cross-sectional epidemiological studies in an adult population, 35-85 year of age in 1983, 2003, 2008 and 2013.

Material and Methods: A random sample of 1012-2243 individuals answered a questionnaire regarding e.g. socio-economic, tobacco habits and oral hygiene habits. A clinical examination was performed including radiographs. Severity of ABL was classified into three categories depending on the amount of bone loss measured on radiographs; no; moderate or severe ABL and manifest caries lesions was registered. Complete data in the different study years were obtained from 78% - 52%.

Results: The prevalence of severe ABL the different study years was 7% in 1983, 5% in 2003, 10% in 2008 and 7% in 2013. The increase between 2003 and 2008 was statistically significant as well as the decrease between 2008 and 2013 (p<0.05).

The prevalence of moderate ABL was 45% in 1983 and decreased significantly to 16% in 2008 but increased significantly to 35% in 2013 (p<0.05).

Calculus seen on radiographs increased significantly from 13% in 2003, 22% in 2008 and 32% in 2013.

The proportion of individuals with at least one manifest caries lesion was 58% in 1983 and decreased significantly to 34% in 2008 and was in 2013 33%. In the age group 85 years, the mean number of decayed surfaces was somewhat higher in 2013 than in 2008 (2.4 vs. 1.2).

After adjustment for age, number of teeth and a number of socioeconomic factors, current/former smoking was the variable that correlated significantly with ABL in all study years (odds ratios ranging from 2.53-3.22). Manifest caries lesions was, after adjustment correlated with irregular dental visits, financial limits for dental care, smoking, low education, daily medication and male gender (odds ratios ranging from 1.24-2.03).

Conclusion: During this period of 30 years ABLand manifest caries decreased significantly. However, between 2008 and 2013 a significantly increase in ABL was found and the positive trend in a decrease in manifest caries ceased. The amount of calculus visible on radiographs increased significantly between 2003 and 2013. Socioeconomic factors was found to have limited impact on ABL but was correlated to manifest caries. Smoking was the overall strongest factor associated with ABL and was also correlated to manifest caries.

Common complications and solutions in Dental implantology

Helme Altaee

Helmis Specialized Dental Center, UAE

The use of dental implants to restore missing teeth has steadily increased over the past three decades. It is perhaps not surprising, then, that the number of implant-related complications has grown as well. Numerous clinical studies involving dental implants have revealed encouraging outcomes; however, there is an element of risk associated with all clinical procedures, and these encouraging results may have given rise to unrealistic expectations. Despite careful planning, there is always a potential for surgical complications. Nevertheless, carrying out routine tasks with care and attention, choosing minimally invasive techniques when indicated, recognizing evidence of a developing problem, and giving prompt attention will reduce postoperative and prosthetic complications. The successful outcome of any surgical and or prosthetic procedure requires attention to a series of patient-related and procedure-dependent parameters. Sound knowledge of surgical anatomy and experience and training in the prosthetic dentistry and implantology are important prerequisites for predictable implant surgery. Also, adequate presurgical planning, good primary stability, a sufficient healing period, and detailed postoperative instructions are all factors that play a vital role in the success of dental implant surgery and osseointegration. Aging, changing health conditions, wear and tear, and inadequate professional maintenance are important variables influencing prognosis. Some hints that we can follow will avoid us many unwanted future complications.

Preventive and interceptive orthodontic treatment: Scope, limitations and expectations

Aiman Abufanas

Ajman University, UAE

Early in the recorded History there were references to dental variations and to the role that orderly transition of the primary to permanent dentition plays in normal development; Celsus observed in 25 B.C. That over retention of primary teeth could Cause Displacement of developing permanent teeth and that finger pressure seemed to help guid the permanent tooth into place after the primary tooth was removed, it is accepted that normal primary dentition and a normal transition from the primary to permanent dentition are necessary to establish a normal adult occlusion.

In the past, children are to begin orthodontic treatment when they reach age 12 to 14 years since all the permanent teeth have erupted by this time. Most dentist extract a tooth to correct bite problem or teeth crowding. However, according to the American Academy of Orthodontics, all children should be brought to the dentist for proper orthodontic assessment by age 7 when the first set of permanent molars had erupted. A prime example of preventive treatment involves space maintenance from premature loss of teeth. Depending on the clinical situation, several techniques can be used to maintain space; The orthodontist who has a much better conception of the possibilities of the prevention of malocclusion unfortunately does not see his patients until the case is ready for corrective measures rather than preventive. Treating children at much earlier ages, say between 7 to 11 years, will take advantage of the childʼs continuing growth and they are more compliant and receptive with treatment at this age.

With interceptive orthodontics, fewer teeth are extracted and there are better results, early Interceptive orthodontics will use patient growth to get best outcome and limit comprehensive face of fixed orthodontic treatment.

For a dentist seeing a young patient with malocclusion the first question is wether orthodontic treatment is needed. if so, the next question is: when should it be done?finally, who should do it? Dose this patient need referral to a specialist?

In this presentation we will cover our current understanding of preventive and interceptive orthodontics; indications, limitations and current procedure done under both categories. Referral concept will be discussed with great emphasis on day to day clinical scenarios that will face general dental practitioner, an example of that patients presenting with posterior or anterior cross bite, impacted teeth and space loss due to premature loss of primary counterpart.

Management of oral habits i.e., (thump sucking, mouth breathing) is essential toward normal development of both dental arches and dentition; ectopic eruption of teeth, supernumerary teeth and delayed eruption all of the above mentioned conditions come under title of interceptive orthodontic treatment which should be an established concept in a successful dental practice.

Understanding normal growth and development of dentitions is key factor in understanding preventive and interceptive orthodontic Treatment; The three major factors involved in development of dentition are Eruption, Drift and Equilibrium, will be covered in the presentation, knowledge of some of the causes of the development of malocclusion and the interceptive measures that may be undertaken during development to limit or reduce the severity of the malocclusion, The rationale and limitations of these procedures will also be discussed.

The effect of magnetic resonance imaging (MRI) on some properties of Acrylic Resin Denture base materials

Ahmed I Al-Khyet

Mosul University, Iraq

Introduction: magnetic resonance imaging have been used nowadays as one of the accepted tool for diagnosis, estimation, and evaluation of many of human been disease; in dentistry, many of prosthodontics patients and "maxillofacial-prosthesis" patients may fall under the category who might be subjected to routine "MRI" check-up either for follow-up of certain disease or cancer patient for determination the degree of healing or metastasis, thus, there has been growing interest in the research of the possible effect of "MRI" procedure on different component of "dental appliances" wears by those patients and one of these components is "heat cured acrylic resin".

Aim: the aims of this study were to evaluate the effects of "magnetic resonance imaging" on mechanical (tensile strength, hardness) physical (color change) chemical (FTIR, NMR) properties at different periods of time exposure.

Material and Methods: total samples of (454) were prepared from acrylic based heat cured denture material, which divided into two main groups "Clear, Pink", each main group was subdivide, into four groups according to exposure to "MRI" control;(5,15, 30) minute each of the four sub-groups undergo different tests" tensile strength, hardness(Rockwell) test, dimensional accuracy test, color change by spectrophotometery, surface roughness, water sorption, residual monomer release "FTIR" and "NMR".

Conclusions: it was concluded that exposure to "MRI" at different periods of time lead to altering of some physical properties at different level of significant with the exception for one to two experiments water sorption and residual monomer which showed less significant than other tests done. Also, FTIR and NMR tests demonstrated a change in vibration of bonds between two, atoms but without rotation of molecule without alter the main chemical structure of material.
