Thermal imaging diagnostics of blistering disease of cheeks and lips caused by the braces; new method and apparatus for prevention of this sudden illness Aleksandr Urakov, A Reshetnikov, M Kopylov and R Gabdrafikov Izhevsk State Medical Academy, Russia
t is found that the timely identification of areas of local hyperthermia has not been possible when using conventional technology Ifor thermal imaging. Therefore, for early detection of incipient corn diseases of the lips and cheeks, we have developed a new technology infrared diagnostics of invisible to the eye local inflammation of the soft tissues. A new method for infrared diagnostics of incipient corn disease from braces based on the provisional short-term local cooling the surface of the oral cavity. Our results showed that the preliminary cooling of the surface of the lips and cheeks several degrees Celsius enhances thermocontractable between healthy and inflamed tissue in damage areas and improves the accuracy of diagnosis of the disease. The obtained results allow to recommend infrared thermography is carried out with a thermal imaging camera to improve the quality of dental care to patients with braces installation, timely detection of early symptoms of the local inflammation of the soft tissues and prevent the development of blisters and sores, i.e. the development of iatrogenic disease that we call corn disease from braces. In addition, the camera allows you to shoot a film about the dynamics of change in temperature in the selected portion of the surface of the oral cavity, which in turn, the machinery can be backed up via flash memory and can be used by dentists as an additional instrument of quality provided to the patient dental care. We invented a new method and device. Their use increases the security of your braces.

Periodontitis peri-implantitis Mohammad Aljalal Ministry of Health, Saudi Arabia
eri-implantitis is an inflammatory destructive process that affects hard and soft tissue surrounding dental implants. Most of the Pbacterial composition that cause peri-implantitis are similar to the bacteria causes periodontitis. Due to prevalence rates up to 56%, peri-implantitis can lead to the loss of the implant without multilateral prevention and therapy concepts. Specific continuous check-ups with evaluation and elimination of risk factors (e.g. smoking, systemic diseases and periodontitis) are effective precautions. Moderate forms of peri-implantitis can obviously be treated effectively using conservative methods same as periodontitis and periodontitis (scaling, root planning and systemic antibiotics), of course after elimination of the local factors. In cases with advanced peri-implantitis surgical therapies are more effective than conservative approaches. Depending on the configuration of the defects, resective surgery can be carried out for elimination of peri-implant lesions, whereas regenerative therapies may be applicable for defect filling. The cumulative interceptive supportive therapy (CIST) protocol serves as guidance for the treatment of the peri-implantitis. In this review, we try to focuses on diagnosis, prevention and treatment of peri-implant disease for practitioners.
Biography Mohammad Aljalal has completed his bachelor degree at College of Applied Medical Sciences (2002) as Medical Lab Technologist. He completed his Master’s Degree and Clinical Certificate in Periodontics. In 2015, he completed his Clinical Certificate in Dental Implants.

TEvaluation of the effect of probiotic yogurt drink (doogh) on salivary Streptococcus mutans Faraneh Abdolhoseinpour, Peyvand Moeini, Kianoosh Khosravi and Mohammad Rahbar Azad University of Medical Science, Iran
Background & Aim: Streptococcus mutans (S. mutans) is a causative agent of dental caries and the use of a few conventional foods containing probiotics is an antimicrobial approach. Both Lactobacilli and bifidobacteria can be found in breast milk, suggesting early exposure of the oral cavity to these bacteria. In this study, we aimed to evaluate the effect of probiotic yoghurt drink (doogh) on salivary S. mutans at Dental Islamic Azad University of Tehran, Iran, in 2011. Materials & Methods: In this double-blind clinical trial, 30 dental students were enrolled and divided into three groups. Salivary S. mutans colonies were counted after consumption of probiotic or ordinary yogurt drink. Growth and the number of microorganisms in each group were compared using sign test and their quantity was tested by performing Wilcoxon test; however, intra-group comparisons were made by using Chi-square and Kruskal-Wallis tests. Results: In the ordinary yogurt drink group, salivary S. mutans level was decreased in 16 (55.2%) cases, while in seven cases (24.1%) it remained unchanged, and in six (22.7%) subjects its level was increased; there was a statistically significant difference between the groups in this regard (P<0.02). However, in the probiotic yogurt drink group, level of salivary S. mutan had diminished in 22 (75.9%) cases, but there was no change in two (6.9%) cases, and the bacterium level was increased in five (17.2%) participants. Sign test reflected a significant difference between the groups (P<0.001). Conclusion: Probiotic yogurt drink reduces the level of salivary S. mutans in the oral cavity of humans. The same effects were found for ordinary yogurt drink, but less than the probiotic type.

Assessment of the effect of fruit (apple) and plain yogurt consumption on plaque PH Sahar Sayahpour, P Moeiny and A Aminikhah Islamic Azad University, Iran
Introduction: Yogurt is believed as healthy and nutrient snack. Nowadays, due to new improvements in producing fruit yoghurts, more tendencies are seen in their consumption especially among children. Therefore, evaluation of their cariogenicity is important. Aim: The aim of this study was evaluation of the effect of two kinds of fruit (apple) and plain yoghurts on plaque PH. Materials & Methods: In this study, 10 healthy dental students were selected. Dental plaque pH in certain area of the mouth was taken by Metrohm microelectrode and digital pH meter. Plaque pH was measured at the baseline and intervals of 2, 5, 7, 10, 15, 20, 30, 40, 50 and 60 minutes after rinsing with test materials, including: fruit (apple) and plain yoghurt (2.5% fat). For positive control group, just the baseline PH and at intervals of 2 and 5 min after swishing with 10% sucrose solutions were recorded. The results were analyzed using repeated measures ANOVA (P<0.05). Results: Lowest pH was obtained after fruit yoghurt consumption followed by plain yoghurt and 10 % sucrose solutions. Furthermore, time duration which remained below the critical pH was longer after consuming fruit yogurt. Conclusion: Both kinds of yoghurt were considered cariogenic since plaque pH drop below the critical points. Average of plaque pH after consumption of fruit yoghurt was significantly lower in almost all the time intervals.

Easy-method for indirect bonding Federico Rosti University of Pavia, Italy
rackets positioning is the most important phase in fixed orthodontics. Accuracy in bonding phase allows reaching easily a correct Btooth position and decreasing the need of repositioning brackets. Indirect bonding allows transferring the right bracket position from model casts to patient's teeth. This technique has several advantages: Best comfort during in office practice, better brackets positioning, less root resorption due to round tripping and shorter appointments for bonding and re-bonding. The aim of this work is to illustrate a simple and homemade technique to realize a PVS mask with a thermal-print coat to transfer bracket position from cast to the patient's teeth. While indirect bonding is recommended in vestibular bonding, it is necessary in lingual orthodontics because of the need of extra skills to bond bracket in the palatal side of the teeth. You can also customize bracket's base with composite resins to correct morphological anomalies, reducing the need of wire bending. This method of indirect bonding is simple and allows physicians to reach, after a short learning curve, good clinical results.
Biography Federico Rosti has completed his Master of Science in Dentistry in 2007 and Post-graduate Degree in Orthodontics at University of Pavia School of Medicine in 2011. His research interest includes “Class 2 corrections, impacted canine, lingual orthodontics, and friction analysis”.

Clinical comparison between free gingival graft healing with and without low level laser therapy Mohammad Taghi Baghani Shaahed University, Iran
Background: Free gingival graft is one of the most predictable procedures for gingival augmentation, but patients discomfort and pain during healing period of palatal donor site is a significant concern. Aim: The aim of this study was to compare between free gingival graft healing with and without low level laser therapy in class one and two miller gingival recession clinically. Material & Methods: 12 individuals needing bilateral gingival graft in the mandibular arch were enrolled in a double-blind study. Each individual had a 30-days interval between the two surgeries. The side receiving application of laser was defined as test side and was established upon surgery; laser application was simulated on the control side. The laser was applied in the immediate postoperative period and after 48 hours, and patients rated pain on a scale of 0 to 10 at 3 h, 24 h and 7th day after surgery, representing their experience of pain, respectively. Photographs were obtained at 0 and 30 days postoperatively and evaluated by three periodontists. Results: 10 patients could make the study to the end. Laser group showed better color matching (P=0.04, P=0.05, P=0.015) and healing in donor site (P=0.000) in day 7, 14 and 21 after surgery and showed less discomfort and pain in 24 h (P=0.007). No statistically differences were observed between laser group and control group in terms of bleeding index and pocket depth and gingival index and gingival margin place (P=0.625). Conclusion: According to the results of this study, the low level laser therapy can improve the discomfort and pain 24 h after surgery and promote donor site wound healing and color matching in graft site.

The role of dentistry in the care of elite athletes: Why elite athletes should be treated as a special case Peter D Fine UCL Eastman Dental Institute, UK
The role of sports dentistry is increasing as professional embraces the concept of good oral health as an integral part of elite athletes’ awareness of the potential influence of diet, regular maintenance and preventative measures. Recent studies suggest that the oral health of elite athletes is inferior to that of a similar cohort in the general population, which is reported to have an impact on their way of life and a perception of having an impact on performance. Following London 2012 Olympic Games, there was a realization that poor oral health was having a negative impact on many of the worlds’ top athletes. The initial study looked at the oral health of 302 Olympic athletes and found high levels of caries, periodontal disease and erosion. Athletes reported that poor oral health was impacting on quality of life and potentially performance. 33% of athletes seeking medical advice at London 2012 attended for dental related problems. A recent study of professional footballers in the UK reported high levels of caries, periodontal disease and erosion. All dental professionals should be encouraged when dealing with elite athletes- regularly at club level, irregularly in the international arena and occasionally at world sporting events. The introduction of screening for elite athletes, greater emphasis on prevention, dentists who appreciate the special issues that athletes present with and good dietary advice from an oral health perspective is all needed if we have to resolve the challenges of the oral health of elite athletes.

Periodontitis: What risks for peri-implants? Periodontal and peri-implant pathologies have a recognized infectious origin Saoudi Fadila Université Saad Dahlab of Blida, Algeria
he logical therapeutic approach will be etiological and its objective will be to reduce or eradicate, not the periodontal flora as a Twhole but its pathogenic component. Microbiology is nowadays a means of diagnosis which makes it possible to demonstrate pathogenic bacteria in the periodontal pockets. This seems judicious in order to better prevent peri-implants in subjects with periodontitis in the past on the one hand and on the other hand in order to better target the treatment. The technique of bacterial culture will be approached to elucidate some precautions to take in order to avoid the loss of certain implants. We will add to this statistics on a sample composed of 21 patients in an area west of Algiers in the center of the Blida town.

Relationship of epidermal growth factor receptor (EGFR) expression and survival rate of SCC patients Sepehr Parhizkar, Fahimeh Anbari, Pourya Motahari, Fereshteh Baghaei, Mahyar Ketabi Moghadam Guilan University of Medical Sciences, Iran
ncreased expression of EGFR on tumor cells is associated with a decrease in survival rate of patients in some cancers. We studied Ithe relationship of the EGFR expression rate with oral SCC prognosis. If we find a relationship between EGFR increase and SCC prognosis, we may benefit from anti-ErbB monoclonal antibody (from EGFR family) in SCC treatment. We used EGFR antibodies for immunohistochemical staining of 38 paraffin blocks of oral SCC. We multiplied stained cells to total cells by intensity of staining to calculate the stainability of the cells. The expression rate of EGFR was matched to mortality or/and recurrence rate of cancer in a few years follow up. Results indicate a significant relationship between EGFR and oral cancer prognosis. Increased EGFR expression predicts poorer prognosis of oral SCC.

Peter D Fine UCL Eastman Dental Institute, London, UK
Prevention of Loss of Tooth Tissue, both Acute and Chronic, in Professional and Amateur Athletes. oth professional and amateur athletes have been shown to loose tooth tissue in an acute way through trauma and in a Bchronic way through erosion. This workshop will discuss the various ways that dentists can influence and prevent the loss of tooth tissue and advise sportsmen and women on preventative measures. Acute trauma is a familiar and dramatic form of tooth loss/damage, the incidence of which can be reduced by appropriate preventative means. Chronic tooth surface loss as result of diet, system illness and poor oral health is much more difficult to recognize and prevent. The screening and education of athletes needs to be considered in order to prevent tooth surface loss as a result of erosion. The workshop will endeavor to discuss the various elements involved in preventing tooth surface loss, the difficulties in educating elite athletes and preventative measures at our disposal. Depending on the number of delegates attending the workshop, I will give a brief introduction to the topic and then divide the delegates into small groups to discuss: i) Preventative measures for acute trauma to the dentition, ii) The role that diet has to play in preventing tooth surface loss, iii) The role that regular screening of athletes has in prevention, iv) The influence of systemic disease ion tooth surface loss and v) What do we have at our disposal to prevent chronic tooth surface loss. Each group will then present their findings to the workshop and conclude with a final summing up.

Retrieval and bypass a fractured instrument: Two case reports Hussien Abdulrahman Alattas Vice Dean, Najran University, Saudi Arabia
Background: A fragment of an instrument, which was separated during the mechanical cleaning and shaping of the root canal system, significantly hinders the proper endodontic treatment and may lead to its failure. Case Presentation: Case I: A 32-year-old healthy female Saudi patient presented at General Dentistry Clinics at College of Dentistry, Njran University, with irreversible pulpitis of the lower left second molar. It was decided to perform root canal treatment and then to do a reconstruction reinforced by crown. During the cleaning and shaping procedures for coronal shaping, a ProTaper nickel- titanium files separated in the mesiolingual canal of the tooth tightly filled nearly 80% of the total length of the canal. The fractured instrument was retrieved. Case II: An 18-year old healthy female Saudi patient reported to the Department of Conservative Dentistry & Endodontic, College of Dentistry, Njran University, with pain in her right maxillary first molar. On examination, a carious exposure was found. Radiograph of the tooth showed a severely curved distobuccal root. During the cleaning and shaping procedures for distobuccal with K3™ nickel-titanium files separated in mid-root with 4 mm of file. The fractured instrument was bypass. Conclusion: Choosing the right method is a key step in the complication described above. The management technique should entail the least risk of iatrogenic complications because they can greatly affect the long-term maintenance of the tooth.

ince Röntgen discovered X-rays in 1895, X-ray imaging techniques have continuously advanced from two-dimensional (2D) Sradiography to 3D tomography such as digital tomosynthesis (DTS) and computed tomography (CT), having been a powerful inspection tool in many applications of medicine, industry, material science, etc. Those techniques have in common attenuation- based contrast which arises from differences in elemental composition, thickness and density of the examined object. However, conventional attenuation-based radiography remains limited by low image contrast especially in imaging materials of low atomic number Z. One possible solution to the problem of limited contrast inherent to attenuation-based radiography is the application of phase-contrast imaging (PCI) technique that utilizes the phase shift introduced by the examined object to the transmitted X-rays. Because the variation in phase of X-rays is much larger than that in intensity due to attenuation, it can detect small features and variations in the object that would be invisible in conventional attenuation-based radiography. In this work, in order to overcome this limitation and to further increase the diagnostic value of DTS examinations, we applied the recently proposed PCI method, the so-called single grid-based PCI to DTS (PCI-DTS). We developed a useful simulation platform for single grid-based PCI-DTS and performed a systematic simulation using a three-dimensional numerical head phantom. In the simulation, an X-ray grid having a 200-lines/in strip density was used and the DTS scan comprised 41 projections within an angle range of 0=±40o with an X-ray energy of 50 keV. We successfully reconstructed PCI-DTS images of much improved image contrast, compared to attenuation-based DTS images, which demonstrates the viability of the proposed approach.

Clinical evaluation of direct composite veneering system for anterior cosmetic treatments with cases presentation Yalda Torabi Ardekani Shiraz University, Iran
variety of treatments exist to treat the anterior teeth defects in order to provide patients with a beautiful smile. Among these Amethods, treatments by acrylic resins, composite veneering restorations, ceramic laminates and full ceramic or porcelain fused to metal crowns can be mentioned. Generally, the majority of dentists and patients prefer more conservative dental cosmetic treatments; e.g., direct or indirect veneer restorations are usually preferred to full ceramic dental crowns. The purpose of this study is clinical evaluation of direct composite veneering system for anterior teeth which is considered as one of the conservative cosmetic treatments to provide an aesthetic smile. 50 composite facing cases, which have been performed in the author's private clinic, are presented in this study. These cases refer to different dental defects such as treatments of diastema between anterior teeth, dental crowding, dentogingival discrepancies and discolorations like tetracycline stain or dental fluorosis, rehabilitation of fractured teeth or dental caries. These 50 cases will be presented with before and after photos in this study.

Layering techniques for aesthetic anterior composite restorations Mayyadah Hamzah AlMozainy King Saud University, Saudi Arabia
n this practical hands-on course, participants learn how to perform a polychromatically layered, highly aesthetic anterior composite Irestoration for fractured or carious incisors. Special attention will be given to multi-layered and multi-colored aesthetic restorative techniques using different translucencies and shades. Course includes a brief lecture and instructional hands-on demonstration of aesthetic anterior composite restorations. Tips and tricks to create the perfect macro- and micro-texture for natural light reflections from the restoration surface will be shown in detail. The ultimate goal is to achieve a highly esthetic and invisible restoration. The latest advances in adhesive and restorative materials have led to the use less invasive treatment modalities to yield highly aesthetic and durable restorations. Mastering anterior direct composite restorations is a necessity for the contemporary clinician who appreciates and understands the art and science of cosmetic dentistry. Natural dentin and enamel vary in thickness, color and morphology; hence, requiring the use of composite formulations that are optically similar to each layer, and sculpting these materials in such a way that replicates the morphology of each anatomical feature being restored. Early brands of composite offered only body shades and appeared dull and dense, contemporary materials offer an expanded range of shades and varying opacities designed specifically for layering of direct restorations. However, the creation of naturally looking restorations can be quite a challenge for clinicians. Learning objectives of this course are: Understanding the color and aesthetics of modern composites; simplified techniques for direct layering of composites; anatomical build-up techniques to restore the tooth shape and; finishing and polishing techniques to create natural tooth like appearance.

The influence of implant placement depth on the accuracy of connecting impression transfers tothe implants Mohammad Taghi Baghani Shahed University, Iran
Background: The exact placement of impression copings is very important in making accurate prosthesis. In some cases, the implants will need to be placed deeply subgingival, which could reduce the direct vision and ultimately reduce precision of impression copings and subsequently, delivered prosthesis. This would be the cause of multiple complications such as delivery of ill-fitting prosthesis. Aim: The aim of this study was to evaluate the effect of the dental implant placement depth on the accuracy of impression coping connection by students. Method: Thisin vitro and experimental study was conducted on 50 senior dental students. Four implants at different depths (0, 2, 4 and 6) were placed in a model. After learning how to mount impression coping on implants, students were asked to mount impression copings on all four implants. Samples were examined by an experienced prosthodontist by a magnifier with 4x magnification. Data were analyzed by statistical Cochran test (P-value<0/05). Results: The proper adapting rate of transfer copings in subgingival implants with a depth of 0, 2, 4 and 6 mm were 100%, 62%, 58% and 20%, respectively. Statistically significant difference was observed between all groups (P-value<0/001). Conclusion: There is an inverse relationship between increasing the depth of the implants in the gingiva and the ability to connect the impression copings by the dentist properly.

Effect of green tea varnish on depth of root caries Zahra Khamverdi and Fahime Daneshyar Hamadan University of Medical Sciences, Iran
Background & Aim: Root caries is a common, debilitating condition particularly in the elderly, which can lead to tooth loss and negatively affect the quality of life and general health of individuals. Evidence shows that green tea has cariostatic effects. Considering the gap of information on green tea varnish, this study aimed to assess the efficacy of green tea varnish for prevention of root caries. Materials & Methods: This in vitro experimental study was performed on 42 sound premolars. Two layers of acid-resistant nail varnish were applied on root surfaces except for a window measuring 1x4 mm. The teeth were randomly divided into three groups (n=14). Group 1 (control) received no intervention. Group 2 received green tea varnish applied on the roots every 48 hours for 21 days. Group 3 received green tea varnish every 24 hours for 21 days. Next, 40 µ sections were cut at the center of window and the depth of carious lesion was measured in three points with 500 µ distance from each other using polarized light microscope. Data were analyzed using SPSS version 16 and non-parametric Kruskal Wallis and Mann Whitney U tests (0.05). Results: The mean (and standard deviation) depth of carious lesion was 54.30±28.64 (µm), 0 and 0 in groups 1-3, respectively. Control group showed the highest depth of caries. Groups 2 and 3 were not significantly different in this respect, but significant differences were noted in depth of caries between groups 1 and 2 and also 1 and 3 (P<0.001). Conclusion: Based on the results, applications of green tea varnish every 24 or 48 hours for 21 days can prevent root caries.

Quick axis: How and when in the diagnostic of TMJ disorders Zenati Latifa, Boukais Hamid and Boukemouche Abdelkader University of Blida, Algeria
Introduction: The diagnostic of temporomandibular joint TMJ disorders is clinical; however, is not always evident and we are obliged to use secondary examens such as axiography registrations. Materials & Methods: We use Quick axis of the firm fag which is mechanical axiography. The total application time is 20 minutes at the same clinical session. Results & Discussion: The condylar inclination shows the position of the disc, muscular coordination. The axiography traces allow us to calculate the reel condylar slope and to program the articulator. Disadvantage of axiography registration is the difficulty in interpreting all the traces. Conclusion: We will be able to treat TMJ disorders (disc problems) only by using Quick axis.
