Management of Class II furcation defects in dogs using combination of Propolis and Nanobone graft
Background: Periodontal regeneration using complementary and alternative medicine has gained considerable attention recently. Propolis is a resinous hive product collected by honey bees from exudates and buds of plants and mixed with wax and bee enzymes.Objective: The aim of this study was to evaluate the effect of propolis as bone graft substitute in the management of experimental grade II furcation defects, and to compare its effect to nanobone and to Propolis/nanobone mixture. Material and Methods: Sixteen critical-sized furcation defects on the buccal surface of mandibular third and fourth premolars were surgically created in twelve dogs and divided into three groups. Group I; defects were filled with Propolis, Group II; defects were filled with nanohydroxyapatite graft and Group III; defects were filled with a combination of Propolis/ nanohydroxyapatite graft. Histologically and histomorphometric analysis of newly formed interradicular bone height and percentage were performed after one and three months. Results: After one month; the three experimental groups revealed the features of early periodontal tissues regeneration including cementum, newly formed bone with inserted newly formed PDL fibers. The propolis group showed the highest bone height and bone surface area. After three months; denser bone occupying larger surface area of the furcation defect were noted especially in the propolis group. Conclusion: The addition of nanobone to propolis showed better results than nano bone alone especially at early healing stage. However, it didn’t show better results than the use of propolis alone.

Vitamin D3 in Alveolar Bone Augmentation Performed Simultaneously with Dental Implant placement. A Controlled Clinical and Radiographic Study
Aim of the study: The aim of this study was to evaluate the effect of vitamin D3 when mixed with xenogenic bone grafts in alveolar ridge augmentation performed simultaneously with implant placement for the management of bony dehiscence defects around dental implant. This included evaluation of the alveolar ridge buccolingual dimensional changes (primary objective) and evaluation of the implant stability changes (secondary objective). Subjects and methods: 14 patients suffering from missing upper anterior tooth and seeking dental implant were included in the study. All the patients showed a residual alveolar ridge with slight bone resorption buccolingually which allowed implant insertion with sufficient stability but with slight bony dehiscence that necessitated simultaneous alveolar bone augmentation with the implant insertion. Group 1 (Test group, 7 patients , received dental implant and alveolar ridge augmentation using customized titanium mesh and xenografts mixed with vitamin D) while Group 2 (Control group, 7 patients, received dental implant and alveolar ridge augmentation using customized titanium mesh and xenografts without vitamin D). Buccolingual (BL) alveolar ridge width changes were evaluated during the study using the cone beam computed tomography (CBCT) while the implant stability changes were evaluated using Osstell Mentor throughout the study. Results: In both groups, a higher mean buccolingual (BL) alveolar ridge width was recorded 4 months after augmentation. The difference between initial and follow up value was statistically significant. Regarding the percent change in BL width, a higher mean percent increase was recorded in group1, with a statistically significant difference between groups. In both groups, a higher mean value of implant stability (ISQ) was recorded 4 months after augmentation. The difference between initial and follow up value was statistically significant. Regarding the percent change in ISQ, a higher mean percent increase was recorded in group1, with a statistically significant difference between groups.Conclusion: Vitamin D enhanced the bone formation when mixed with xenografts in alveolar ridge augmentation surgeries. Moreover, it played a role in improving implant stability .

Radiographic assessment of impacted maxillary canine position using CBCT: A comparative study of 2 methods
Objectives: The aim of this study was to compare and evaluate the guidelines proposed by Counihan et al 2013 and the KPG index method for assessment of maxillary impacted canine position using CBCT images from a radiographic point of view.Subjects & methods: Thirty-six CBCT scans of 36 patients (6 males and 30 females), with a total number of 45 impacted maxillary canines, were recruited from the database of the Oral and Maxillofacial Radiology Department, Faculty of Dentistry, Cairo University. KPG index, for each impacted canine, was calculated by giving both its cusp and root tips a score on a 0–5 scale along the x, y, and z planes. The summation of these six scores would predict the treatment difficulty, classified as easy (0–9), moderate (10–14), difficult (15–19), and extremely difficult (20 and above). Moreover, Counihan et al 2013 guidelines were applied on each studied impacted tooth in which the tooth position in four categories was considered: overlap with adjacent incisor, vertical height, angulation to midline and position of root apex. For each category, either good, average or poor prognostic outcome was selected. Data were collected and statistically analyzed.Results Upon comparing both studied methods of radiographic assessment of impacted maxillary canines, a statistically significant difference was found: KPG index categorized more cases (9 cases) as easy (20%) while Counihan et al guidelines categorized only 2 cases (4.4%) as having good prognosis. Similarly, KPG index categorized more cases (15 cases) as moderate (33.3%) while Counihan et al guidelines categorized 13 cases (28.9%) as having average prognosis. On the other hand, Counihan et al guidelines categorized more cases (30 cases) as poor prognosis (66.7%) while KPG index categorized only 21 cases (46.7%) as being difficult. Nonetheless, on comparing the treatment difficulty and prognosis of impacted maxillary canines found on the right and left sides, unilaterally or bilaterally, in males and females, a non-statistically significant difference was found using both methods of radiographic assessment.Conclusion From a radiographic point of view, the KPG index, with some minute modifications, has demonstrated to be an effective and competent method for classification of maxillary impacted canine’s treatment difficulty in accordance to their position, as compared to the guidelines proposed by Counihan et al at 2013.

Effect of topical steroid therapy of bullous erosive lichen planus on serum and salivary levels of advanced glyacation end products
Introduction: Lichen planus is a relatively common chronic inflammatory disease. The bullous erosive type is characterized by the high risk of developing squamous cell carcinoma. AGEs are believed to generate chronic inflammation.Methodology: The study was carried on thirty participants; they were divided into two groups. Group (1): included 15 healthy participants free of any systemic diseases. Group (2): included 15 patients of bullous erosive oral lichen planus and free of any other diseases. Serum and salivary samples were taken from all participants at initial visit and after complete resolution of the lesions in the OLP patients using topical application of 0.1% or 0.05% betamethasone valerate gel. Results: In serum, whether before or after treatment, OLP group showed statistical significantly higher mean AGE levels than the control group. In saliva, before treatment, OLP group showed statistical significantly higher mean AGE levels than the control group. After treatment, there was a statistically significant decrease in AGE level. Conclusion: Both salivary and serum levels of AGE are valuable biomarkers in diagnosis and prognosis of OLP. Detection of AGE level in saliva can be considered as a valuable non-invasive method for diagnosis and prognosis of OLP.

Histological and Immunohistochemical Study of Selenium Regenerative Effect on Submandibular and Sublingual Glands of Aging Rats
Background: The role of Selenium as an antioxidant has become a point of interest for its importance in prevention of cancer and other systemic diseases especially those associated with aging.Objectives: The aim of the present investigation was to investigate the effect of Selenium supplementation on the submandibular and sublingual salivary glands of aging rats through:1- Histological examination. 2- Immunohistochemical localization of Ki67.Materials and Methods: Thirty young adult male albino rats with body weight ranged from 80-110 gram and of 2 month age were used and divided into the following groups. Group I (control group): Consisted of 20 rats, subdivided into 2 subgroups. Group I.1:10 animals were sacrificed after one month to serve as young controls. Group I.2:10 animals were left till the end of the experiment to serve as old controls. Group II: 10 animals received Selenium 150 µg/kg diet for the whole experimental period. The experiment lasted for 9 months.Results: histological results revealed that aging caused devastating effects on the histological structure of submandibular and sublingual salivary glands. Selenium markedly modulated the action of aging process and increased the regenerative capacity of submandibular and sublingual glands. According to expression intensity of Ki67 stain in submandibular and sublingual glands, there was statistically significant difference between young, selenium and old groups. In general, expression intensity of Ki67 stain was the highest in the young control group followed by selenium group and lowest in old control group. Also, ki67 expression was significantly higher in sublingual than submandibular glands. Conclusions: Selenium was documented to have a powerful and beneficial antiaging effect. This faced lights around the promising role of selenium in the new era of regenerative medicine. Sublingual gland was more resistant to regressive changes of aging than submandibular gland.

Assessment of Proximity of Maxillary Molars Roots to the Maxillary Sinus Floor in a Sample from the Egyptian Population using Cone-beam Computed Tomography (Hospital Based Study)
Aim: To assess the proximity between the roots of maxillary molars and Maxillary Sinus Floor ‘MSF’ using CBCT in a sample from the Egyptian population.Materials and Methods: Eighty seven CBCT scans of adult Egyptians (29 males and 58 females) involving 135 maxillary 1st molars, 168 maxillary 2nd molars and 107 maxillary 3rd molars, were collected from patients’ data base of Planmeca Promax 3D Mid CBCT machine available at the Department of Oral &Maxillofacial Radiology, Faculty of Dentistry, Cairo University. The vertical relation between MSF and examined teeth roots was assessed on cross sectional CBCT images based on Jung classification 2009 Results: In all mesio-buccal “MB’, disto-buccal ‘DB’& palatal ‘P’ roots of the examined teeth, the 1st molars showed the highest prevalence of class (0) in the 3 roots, while the 2nd molars showed the highest prevalence of class (3) among both MB & DB roots, and the highest prevalence of class (2) among P roots, finally 3rd molars showed the highest prevalence of class (1) among DB roots, and the highest prevalence of class (3) among P roots. There was a significant inverse correlation between age and vertical relationship classes of only the first maxillary molars roots. Males showed higher prevalence of Class (2) and Class (3) while females showed higher prevalence of Class (0) and Class (1) in the 3rd molars.Conclusion: In the investigated Egyptian subjects, maxillary 1st molars’ roots are the least close to the MSF compared to the other molars roots, while buccal roots of maxillary 2nd molars are highly anticipated for MSF invagination. The lower the age is, the closer are the maxillary 1st molar roots to the MSF, and males’ maxillary 3rd molars are more frequently approximating MSF than females.

Histological and Immuno-histochemical Study of the Cytotoxic Effects of Gold Nanoparticles on the Palate of Albino Rats
Aim: The aim of the present work was to study the possible cytotoxic effect of gold nanoparticles on the palate of albino rats using routine H&E stain, Masson’ trichrome and immuno-histochemical detection of any possible changes in NF-κB (nuclear factor kappa). Materials and methods: Forty-six adult male albino rats with an average of 150-180 gram body weight were used in this investigation. They were housed in rat cages, (five rats per cage), and labeled with numerical numbers and kept in well ventilated animal house at the faculty of dentistry, Suez Canal University, at temperature 27-30°C, 12 hours natural light and 12 hours darkness. The animals were fed with dry pellet and allowed drinking water adlibitum. Animals were divided randomly into three groups as follows: Group 1: consisted of 16 rats that received a daily intraperitoneal injection of AuNP solvent (0.5 ml deionized water) for 21 days and served as controls. Half the animals of the control group (sub-group 1.1) were euthanized after 21 days, while the other half (sub-group 1.2) were left untreated for one month, then euthanized. Group 2: consisted of 15 rats that received 10mg/kg body weight /day of AuNPs solution dissolved in 0.5 ml deionized water with particle size around 30 nm intraperitoneal for 21 days. Group 3: consisted of 15 rats, they were treated as group 2 for 21 days and then left for one month as a recovery period.The experiment lasted for 21 days for group 2 then the rats were euthanized by cervical dislocation. While the rats of group 3 were euthanized after one month for recovery. The palate of all animals were dissected out, fixed in 10% neutral buffered formalin, processed and embedded in paraffin. Four to five microns thick sections were cut to be stained with; hematoxylin and eosin for histological examination, Masson’s trichrome stains for collagen evaluation and immune-histochemical localization of NF-κB (nuclear factor kappa) for detection of any possible cellular changes.Results: The histological and immune-histochemical results revealed atrophy and degenerative changes in the palatal tissues associated with increased expression of nuclear factor kappa. A recovery period of one month resulted in regeneration and improvement in the histological structure and function of the tissues.

Comparative Assessment of Maxillofacial Morphology in Patients with Bilateral Cleft Lip and Palate using Cone Beam Computed Tomography
Objective: The purpose of this study was to investigate maxillofacial morphology using CBCT with the ultimate goal of finding whether differences existed in a two suggested subtypes of non-syndromic bilateral cleft lip and palate (BCLP) patients. Design: This retrospective study included CBCT data of 22 BCLP patients with mean age of 9.6 years. The patients were divided initially according to premaxillary characteristics into two groups and this classification was further confirmed by measurement of sella–nasion– point A angle (SNA), Group (P): This represent BCLP characterized by well-developed (P) prominent pre-maxilla and SNA >80±2, Group(R): This represent BCLP characterized by ill-developed (R) rudimentary pre-maxilla and SNA < 80±2. The relation between maxilla and mandible measured by point A–nasion–B point angle (ANB), angle of septal deviation (ASD) and anterior upper facial height (AUFH) were assessed using On-demand 3D software and was compared among the two groups. Results: Patients within group P showed significantly higher ANB (P value ≤ 0.001). Patients within group R showed significantly higher ASD angle (P value ≤ 0.05), while AUFH showed insignificant difference between the two groups (P value ≥ 0.05). Conclusions: Maxillofacial morphology measurements assessed in this study support that difference exist between the two investigated subtypes of non-syndromic BCLP.

In Vivo Biocompatibility of β Tri-calicum Phosphate Versus White Portland Cement in Mandibular Bone Surgical Defect in Dogs
Back ground: Synthetic bone substitutes have been advanced, and researches are developed to more effective biomaterials with promising ability to reconstruct lost bone structure. Tricalcium phosphate biomaterials and white Portland cement are among them. The aim of the current study is to assess the effect of β-tricalcium phosphate versus white Portland cement in surgically mandibular bone defect dogs.Material and methods: Six adult dogs were used. The anaesthesia was conducted by iv injection of thiopental sodium 20mg/kg.b.wt. and maintained using (atropine 0.04 mg/kg b.wt., xylazine 1mg/kg.b.wt. and diazepam 1mg/kg.b.wt.in saline iv drop by drop infusion ), three critical size defects were designed at the buccal side of the mandible. The defects were 5 cm apart from each other. One defects filled with sterile white Portland cement, the middle defect filled with β-tricalcium phosphate and the later one was left empty. The dogs were euthanized at the end of 1 and 8 week postoperatively respectively. The specimens were prepared for light microscope using H&E and Masson Tri-chrome staining.Results: The experimental sides of all periods revealed increasing the amount of new bone trabeculae extended from original bone towards the center of the defect with both white Portland cement & β-tricalcium phosphate. While, the control sides displayed few new bone trabeculae at central area and the lateral wall of the bony defects. The amount of new bone trabeculae confirmed the histological results. Conclusion: White Portland cement is a biocompatible osteoconductive economically affordable graft material and it id more efficient than β-tricalcium phosphate.

Clinical and Radiographic Outcomes of Immediate Implant Placement With or Without Nanocrystalline Bone Grafting Material in The Facial Gap Distance: A Randomized Clinical Trial
Objectives: The aim of this study was to evaluate the clinical and radiographic outcomes of the simultaneous use of nanocrystalline bone grafting material placed in the facial gap distance around immediate dental implants placed in the anterior maxilla and its effect for minimizing the crestal bone loss. Material and methods: Adult patients were eligible for the study if they needed one immediate implant placement (IIP) replacing a tooth to be extracted within the maxillary anterior region. The patients included in the study were divided into two groups; patients in the first group received IIP without grafting material in the gap distance while patients in the second group received IIP simultaneously with nanocrystalline bone in the facial gap distance. Clinical and radiographic assessments were performed before IIP (baseline) and scheduled 4 and 12 months after implant placement. Clinical assessment included bleeding Index (BI) and probing depth (PD). Facial bone height measurements were performed using cone beam computed tomography (CBCT) to measure the crestal bone loss.Results: The means of BI and PD values at the 12 months follow up indicated healthy peri-implant soft tissues for both groups, however higher means of BI and PD were shown in IIP without grafting material when compared to IIP with nanocrystalline bone in the facial gap distance. There was no statistically significant difference in CBL between both groups (p=0.924).Conclusions: The short-term follow-up of 12 months of IIP in the maxillary anterior area revealed successful clinical outcomes as assessed by objective parameters. IIP with or without simultaneous nanocrystalline bone grafting material placed in the facial gap distance around the implants did not prevent crestal bone loss as assessed by CBCT.

MANAGEMENT OF LATERAL PERIODONTAL CYST EMBEDDED IN BONE
Lateral periodontal cysts (LPCs) are odontogenic cysts with rare occurrence and developmental origin. A 46-year old female patient, chronic smoker with non-contributory medical history presented with dull pain/pressure in the left mandibular premolar region and the associated teeth were vital on pulp testing. Periapical radiograph revealed a well- circumscribed, radiolucent region measuring <1cm in diameter with loss of lamina dura in teeth, which were in contact with the lesion, and interproximal buccal bone loss. The clinical and radiographic features were suggestive of LPC and the patient was advised to undergo conservative surgical management of the cystic lesion. The full-thickness mucoperiosteal flap was elevated, complete debridement was done, and enucleation was performed using a surgical curette. The flaps were approximated and then sutured. Histological examination was performed on the tissue sample obtained during surgery and the findings confirmed the diagnosis of LPC. The post-operative follow-up was uneventful with no biological complications such as pain, swelling, or bleeding at the surgical site and periodontal healing was satisfactory.

Introduction: Removable dentures are being used as a replacement for missing teeth to restore function and aesthetics that has resulted in improved quality of life. However, different orofacial lesions may be presented as an associated complication to these appliances.Aim: The present study aims at investigating the prevalence of denture-related lesions (DRLs) among the denture wearers.Method: This was a descriptive, cross-sectional study. Clinical examination of 167 individuals with dentures was conducted from December 2013 to April 2014. Data form was designed to collect general information including personal data (e.g., age, gender), smoking practice, and frequency, duration and number of DRLs. The data were analyzed using the IBM SPSS software, version 22 (SPSS, Inc. IBM, Chicago, IL, USA). The responses were expressed as percentages.Results: A total of 167 patients (82 men and 85 women) with a mean age of 58 years were enrolled in the present study. Of them, 84 had partial dentures while 75 had complete dentures. Eight patients had upper complete dentures and lower partial dentures. Different DRLs were reported. Sixty-six participants (39.5%) had one or more denture-related abnormalities. Traumatic ulceration was the most common denture-associated lesions and was observed in 25 (15%) participants.Conclusion: DRLs were found to be more common among complete denture wearers than in partial denture wearers. However, regular follow-ups would help in early detection of the unnoticed abnormalities or complications of the dentures.

Topical management of recurrent aphthous stomatitis
Recurrent aphthous stomatitis (RAS) is a common condition that is affecting young adults. The management of RAS aims at identifying and controlling the possible predisposing factors, exclude possible underlying systemic causes, control pain and to accelerate healing. A wide variety of systemic and topical agents has been suggested for the treatment of RAS. Although there are several trials employing different systemic and/or topical agents in the treatment of RAS, there is no strong evidence on the superiority of any therapeutic or curative agent for this disorder. Topical agents may be sufficient to lessen the pain in some patients; however systemic corticosteroids/immunosuppressant agents may be necessary to control pain in others. Therefore, the severity and frequency of ulcers may be used as guidance in the management of RAS patients. This paper reviews the available topical agents that have been used in the management of RAS.

Impact of Local Injection of Human Growth Hormone versus Low-Level Laser Therapy on Mandibular Condyle in Arthritic Guinea Pigs
Objectives: This study aimed to compare the effect of intra-articular injection of human growth hormone (HGH) versus low-level laser therapy (LLLT) on mandibular condyle in arthritic guinea pigs.Methods: A total of 30 male guinea pigs with average weight (250g -350g) had a temporomandibular joint (TMJ) arthritis induced by locally injecting complete freund’s adjuvant (CFA) intra-articularly in the right side. Then they were divided into three groups; control, HGH and LLLT. The applications of both treatments were done every two days for two weeks, then all groups were euthanized. Arthritic TMJs were dissected and processed for histological, histomorphometric and statistical analysis.. Results: Histological evaluation showed increased thickness of articular cartilage and formation of new subchondral bone trabeculae and narrowing of marrow spaces in both study groups with statistical significant differences compared to control group.Conclusion: Treatment of TMJ arthritis with HGH showed improvements in all parameters tested. HGH can be a promising modality to repair degenerative changes associated with CFA induced arthritis.

COMPARISON OF DEBRIDEMENT EFFICACY AND PERIAPIACL REPAIR USING APICAL NEGATIVE PRESSURE IRRIGATION VERSUS SYRINGE IRRIGATION- A SYSTEMATIC REVIEW
Irrigation is considered an indispensable part of root canal treatment as it fortifies the cleaning and disinfection of areas of the root canal system that have been inadequately influenced by instruments. The aim of this systematic review was to collate published data on the two modes of irrigation i.e., conventional irrigation and apical negative pressure irrigation (ANP) for cleaning and shaping of the canals and to compare their efficacy in debridement and periapical tissue repair. The electronic databases PubMed and Google Scholar were searched in this review using specific inclusion and exclusion criteria. The search was performed in June 2018 and updated in March 2019. Among 1481 studies, five studies satisfied the eligibility criteria and were included in the review to be analysed. These studies compared the effectiveness of ANP method against syringe irrigation in removing debris within the root canal system and their effect in periapical tissue repair, including: different types of irrigation methods, debris removal during cleaning and shaping, and updating studies of their effect in periodontal and periapical repair. The compiled data observed that ANP was more efficient in removing the debris and offered a greater advantage that should lead to wider acceptance among dentists for effective results compared to different irrigation systems. However, more clinical trials with standardized protocol and defined clinical, radiographic, and histopathological outcomes with longer follow-up periods are warranted.

Evaluation of adjunctive effect of daily dietary supplements with omega 3 and propolis to non-surgical periodontal therapy: Randomized Clinical Trial
Background and Objective: This study aimed to investigate the systemic effect of dietary supplement omega 3 (ω-3) polyunsaturated fatty acids (PUFAs ) and propolis as an adjunct to non surgical periodontal therapy and evaluate the gingival crevicular fluid level of receptor activator of nuclear factor κ ligand (RANKL). Material and Methods: Forty-five subjects with stage II or III and grade B periodontitis were included in this study. They were randomly assigned into three groups: Group I: 15 subjects received scaling and root planing (SRP) only. Group II: 15 subjects received SRP combined with daily dietary supplementation of omega 3 for 6 months. Group III: 15 subjects received SRP combined with a daily dietary supplement of propolis for 6 months. Clinical parameter (plaque index, bleeding index, pocket depth, and clinical attachment level) and biochemical analysis of RANKL in GCF were recorded at baseline, 3 months and 6 months after treatmentsResults: Statistical analysis revealed that both (ω-3) and propolis statistically significant (P≤0.01) reduce PD and CAL at 3 and 6 months compared to its baseline and control group. RANKL level in GCF statistically significant (P≤0.01) reduced at 3 and 6 months in both treated groups compared to its baseline and control group. No statistical significant (P≥0.05) difference between both treated groups concerning clinical and biochemical parameters.Conclusion: The present study suggests that dietary supplementation with ω-3 PUFAs or propolis effective as an adjunct to nonsurgical periodontal therapy in the management of patients with periodontitis.

Effect of Diode Laser combined with Hyaluronic Acid Gel in Treatment of Recurrent Aphthous Stomatitis in Children: Randomized Clinical Trial
Background: Recurrent Aphthous Stomatitis (RAS) is a painful rounded ulcer characteristic by erythematous margin and pseudo yellowish- gray membrane in its center. All forms of RAS have bad effects on quality of life that interfere with daily activities. Hyaluronic acid has essential part in tissue hydrodynamics, cell migration, proliferation and differentiation. It shows an anti-inflammatory role so; it prevents tissue destruction and helps in tissue healing. Low level laser therapy is recognized with various terminologies such as “biostimulator,” and “cold laser,” It has role in the management of RAS, it has a wide spectrum of clinical applications which include herpes labialis, angular cheilitis, trismus, paresthesia, dentin hypersensitivity, temporomandibular joint pain, and in the postoperative phase.Materials and Method: Forty five normal healthy males and females children aged from (4-10 years) suffering from aphthous lesions were used in this study. Children were examined in Outpatient clinic pediatric Dentistry Department, Faculty of Dentistry, Suez canal University by a clinician. Each patient had one minor RAS of less than 72 h duration or two nearby minor aphthous lesions of less than 72 h at the same side of oral cavity. Patients were evenly divided into three groups (15 patients in each) with the method of simple randomization, Patients of group I were treated with topical application of hyaluronic acid gel , those of group II were treated with diode laser and group III patients were treated with diode laser followed by topical application of hyaluronic acid gel. The patients were evaluated at (0, 2nd, 4th and 6th) days, for measuring ulcer size and pain score. Results: At the 2nd, 4th and 6th days there was statistical significance decrease in mean size of the ulcer of group III when compared to both groups (I) and (II) . On other hands, at days 2 and 6 there was statistical significance decrease in mean of pain score in group III when compared to group I. There was also statistical significance decrease in mean of pain score in group II when compared to group I at the 4th day of evaluation.Conclusion: Hyaluronic acid gel combined with diode laser are effective in treatment of RAS.

Radiographic Caries Detection Behavior in a Sample of Dentists and Dental Specialists
Radiographic caries detection depends not only on correctly acquired radiographs but also on the way they are displayed and interpreted. Objective: This research aims to measure behavioral factors important for caries detection among dentists. Materials & Methods: A sample of 206 dentists was surveyed using a self-reported questionnaire after a focus group and a pilot study. Questions asked were related to the type of image used, the way the image is displayed, the use of magnification, and the use of vision correction aids if needed. Responses were analyzed using descriptive statistics. Results: The use of the following was BW (>95%), viewing box (68%), masking extra-light (<15%), dimming room’s light (<15%), magnification (<13%), and vision correction aid (85% from those who need it). The most frequently reported reasons were “availability” and “lack of knowledge”. Conclusions: There is a significant undesirable behavioral practice during radiographic caries detection among the studied sample. The main reasons seem to be “convenience” and lack of knowledge.
