EFFECT OF DIFFERENT ETCHING TIMES ON SEALANT PROPERTIES APPLIED TO FLUORIDE TREATED TEETH: AN IN VITRO STUDY
This study aimed to investigate the effect of fluoride varnish on microleakage and the interfacial micromorphology of pit and fissure nano sealant after different etching times.Materials and methods: One hundred freshly extracted third molars were used in this study. They were randomly allocated into control group (20 teeth) and test group (80 teeth) which was further subdivided into 4 subgroups each one contained (20 teeth) according to the etching time. Teeth of the test group were subjected to fluoride varnish application. The next day, each subgroup was acid etched according to its specific time (20, 40, 60, and 120 seconds for groups I, II, III and IV respectively). Nano fissure sealant was then applied to all teeth according to the manufacturer instructions. Teeth in the control group received the nano sealant without fluoride application. Ten teeth from each subgroup were used for interfacial micromorphology scanning, and the other 10 teeth were used for microleakage evaluation. Results: The scanning electron microscopic examination revealed that the formed tags varied between the groups. The shortest tags were found in subgroup I (between 2.24-3.22 µm), while the largest were in subgroup IV (35.19- 35.24 µm). Score 0 microleakage was the significantly highest one in all groups. The comparison between test groups and control group revealed significant differences in score 1 and 3 only.Conclusion: Application of fluoride did not affect the sealant application especially for the etching times 40 and 60 seconds.

COMPARATIVE STUDY OF SHEAR BOND STRENGTH BETWEEN CONVENTIONAL AND FLOWABLE ORTHODONTIC ADHESIVES
Introduction: Flowable resin composites have been recommended for many clinical uses and have been formulated in a variety of compositions and viscosities to meet various uses.Aim of the work: To determine if flowable composite with or without primers could be used in orthodontic bracket bonding. Materials and Methods: Sixty human premolars and sixty metal brackets were randomly and equally divided into four subgroups. 1A subgroup (TXT with primer), 1B subgroup (TXT without primer), 2A (GF with primer) and 2B (GF without primer). After 72 hours, debonding was performed with a shearing force. The SBS (Shear Bond Strength) and the mode of bond failure were examined with ARI. Another twenty eight teeth were bonded by the same protocol to evaluate microleakage after thermocycling and dying with 2% methylene blue dye for 24 hours.Results: Respective SBS results of the four subgroups were 14.6 ± 5.3, 13.3 ± 6.8, 18.9 ± 6.1 and 12.5 ± 5.9 MPa respectively. SBS value of subgroup 2A were significantly higher than subgroups 1A, 1B and 2B. After debonding ARI scores 0 and 1 were predominant in subgroups 1A, 1B and 2B, where subgroup 2A had ARI scores of 1 and 2. Subgroups 1B and 2B showed microleakage at both bracket-adhesive and enamel- adhesive interfaces, while subgroups 1A and 2A only 43% showed microleakage at bracket-adhesive interface. Conclusions: Flowable composite (GF) can be successfully used for bonding orthodontic brackets as it provided SBS comparable with conventional composite (TXT), as well as can be used without primer as it gives a clinically acceptable SBS and favorable bond failure pattern. However, from microleakage point of view flowable composite (GF) with primer demonstrated the best performance.

A STUDY OF BIDIRECTIONAL RELATIONSHIP BETWEEN DIABETES MELLITUS AND PERIODONTAL DISEASES IN CHILDREN
Although periodontitis does not belong to clinical manifestations of any type of diabetes mellitus, it is still being labeled as “the sixth chronic complication of diabetes. It has been confirmed that, in individuals with diabetes, there is about a three times higher risk of periodontitis. Thus, diabetes is considered to be a predisposing factor for periodontitis .In the diabetic patients, the periodontal disease develops at a younger age than in the healthy population. The aim of this study was to prove the bidirectional relationship between periodontal diseases and diabetes type 1 in children. Patients and Methods: this study was conducted on 40 children with age range from 8-13 years, for evaluation of periodontal diseases “Gingival Index (GI), Plaque Index (PI) and Clinical Attachment Loss (CAL)” were used, and “Glycosylated hemoglobin (HbA1c %)” for the evaluation of blood glucose level and after application of the dental treatment program the patients were reevaluated after 3months, 6months and 9months. Results: the results show that both periodontal diseases and diabetes type 1 had a bidirectional relationship.

EFFECT OF ENERGY BEVERAGES ON THE ENAMEL HARDNESS AND SHEAR BOND STRENGTH OF ORTHODONTIC BRACKETS (IN-VITRO STUDY)
The purpose of the present study was to investigate the effect of energy (sports) drinks on enamel hardness and shear bond strength of orthodontic brackets. Seventy maxillary first premolar teeth were divided into three groups. In Group I, the enamel hardness was measured with Vickers knoop hardness tester, after immersing the teeth in the distilled water (control) and energy drink for , one, two and four weeks. In group II, after 2 weeks of storage in the beverage and distilled water, the teeth were bonded with standard metal stainless steel brackets, using Concise composite resin, after which the SBS was immediately measured. Then the coefficient of correlation between hardness and SBS of group II was recorded. In group III, the teeth were stored in the beverage and water with bonded brackets, as in group I. The SBS was then measured. The 2 weeks and 4 weeks beverage groups showed the significantly lowest enamel hardness values with no difference between them. A positive correlation (r = 0.89) was found between enamel hardness and SBS. The 4 weeks beverage storage showed the lowest SBS followed by 2 weeks storage, but the values were clinically acceptable. Thus, it was concluded that energy drinks significantly reduced enamel hardness and SBS, and this reduction was proportional to period of storage.

EVALUATION OF ANTIMICROBIAL EFFICACY OF GREEN TEA EXTRACT IRRIGANT VERSUS PHYSIOLOGICAL SALINE FOLLOWING ROOT CANAL TREATMENT OF INFECTED PRIMARY MOLARS IN A GROUP OF EGYPTIAN CHILDREN : A RANDOMIZED CLINICAL TRIAL
Introduction Preservation of primary tooth with non-vital pulp is a major problem in pediatric dentistry. In such cases, the preferred treatment modality is pulpectomy. The objective of pulpectomy is complete removal of necrotic and irreversibly infected pulp of an affected tooth but due to limited ability of mechanical preparation to eliminate entrapped micro organisms in the canal space owing to the tortuous and complex nature of the root canal system. Thus , the use of antimicrobial agents has been recommended as an adjunct to mechanical instrumentation in deciduous teeth.Aim The aim of the study was to assess the antimicrobial efficacy and clinical success of green tea extract irrigant versus physiological saline following root canal irrigation of infected primary molars.Materials and Methods In the present study, antimicrobial efficacy and clinical success of green tea extract irrigant and physiological saline as control were assessed and compared with each other. The antimicrobial efficacy was evaluated against aerobic and anaerobic. The statistical analysis was done with IBM, SPSS*. Statistics version 23 for Windows. Data were explored for normality using Kolmogorov-Smirnov and Shapiro-Wilk tests. Log10 (CFU/ml) showed parametric distribution, so Dependent t-test was used to compare between before and after application. Independent t-test was used to compare between different groups.Results: Percentage of change in bacterial count of aerobic and anaerobic bacteria revealed significant difference in preference to green tea extract group . Clinical success was higher in green tea extract group.Conclusion: Green tea extract irrigant has antimicrobial effect against aerobic and anaerobic bacteria present in the root canals of necrotic primary molars which is higher than saline. Also, green tea extract irrigation showed higher clinical success rate than saline.

TOOTH AVULSION MANAGEMENT: STATE OF DENTAL STUDENTS’ KNOWLEDGE
Aim: This study was conducted to determine the knowledge of undergraduate dental students regarding the management of avulsed teeth at the College of Dentistry, King Saud University, Riyadh, Saudi Arabia.Methods: A self-administered English-language questionnaire contained of 17 close ended questions with two parts: The first part consisted of questions about demographic and professional data. The second part of the questionnaire consisted of questions to evaluate the knowledge and attitude of the students on managing avulsed traumatic injuries. The data were entered and analyzed using SPSS. The level of statistical significance was set at p < 0.05. Results: Data were collected from 303 students with response rate of 83.4%. About 80% of the students had a previous knowledge about dental trauma. Most of the students 92.7% were able to define avulsion, correct answers were significantly more with advanced academic level (P = 0.003). Majority of the students (80.5%) can distinguish between primary and permanent teeth. About half of the study group (46.2%) correctly answered the ideal time for re-implantation, more female students were responded correctly with p = 0.000 if compared to male students. Most of the students (83.8%) selected milk as a storage medium, almost 15% selected saliva, 14.5% selected Hank’s balanced salt solution (HBSS) and 8.3% selected saline. Only 19.8% answered the flexible splint used for splinting avulsed teeth with significant difference in different academic level and gender p < 0.05.Conclusion: The present study reflects insufficient knowledge of dental students in management of avulsed teeth. In some points the students’ knowledge needs to be improved through enhancing and providing different kinds of education methods in undergraduate courses.

RANDOMIZED CONTROLLED STUDY FOR EVALUATION OF BIODENTINE AND ENDOCEM ZR AS A TREATMENT OF REVERSIBLE PULPITIS IN MATURE PERMANENT TEETH ON PEDIATRIC PATIENTS
Aim The aim of this study was to evaluate and compare the clinical outcomes of vital pulpotomy using biodentine (Septodent, France) or Endocem (Maruchi, Wonju, Korea) as pulp capping materials in a prospective randomized controlled study. Materials and Methods This study was conducted in 20 subjects who were recruited from patients of the Department of pediatric dentistry of Misr University For science and Technology, Cairo, Egypt. All the patients in this study (10-13 year) were suffering from reversible pulpities in their mature permanent molars, a total of 40 teeth were randomly assigned to either the Biodentin or the Endocem group (20 teeth per group). Vital pulpotomy was done using these 2 materials, and clinical and radiographic evaluations were performed at 6weaks, 6 months, and 1 year follow up period. Teeth with negative response to vitality test and those who exhibit signs of irreversible pulpitis or pulp necrosis were considered as failures. Results In the 6 weeks, 6months and 1 year follow up, the clinical success rates for the ENDOCEM Zr was 95%. 90% and 90%, respectively and the radiographic success rates were 100%, 90% and 90% respectively. Regarding biodentine pulpotomy, the clinical and radiographic success rate in 6 weeks, 6months and 1 year follow up was 100%, 95% and 95% respectively. The difference between biodentine and MTA groups was statistically non-significant (p = 0.7646>0.05).Conclusions in this randomized controlled study, Biodentine has clinical and radiograghic success rate comparable to ENDOCEM Zr as a vital pulpotomy in mature permanent molars with carious exposures.

CONE BEAM COMPUTED TOMOGRAPHY ASSESSMENT OF THE R LATION BETWEEN SEX AND MORPHOLOGY OF MAXILLA IN PATIENTS WITH IMPACTED MAXILLARY
Maxillary canine impaction is a relatively common clinical problem and radiographic examination plays a crucial role in diagnosis and treatment planning. Objective: To study the relation between sex and morphology of maxilla in patients with maxillary canine impaction using cone beam computed tomography (CBCT). Material and methods: The study sample consisted of the CBCT records of 90 subjects obtained before any surgical or orthodontic intervention. The records were divided into 2 main groups, Group I: the male group, consisted of 44 subjects divided into three subgroups, I a: the normally erupting maxillary canine subgroup (control group), I b: the buccal impaction canine subgroup and I c: the palatal impaction canine subgroup. Similarly, Group II: the female group, consisted of 46 subjects also divided into three similar subgroups. From the CBCT images, the following measurements and ratios were obtained to assess the maxillary morphology: inter-molar width, arch length, palatal vault depth, maxillary transverse skeletal width and nasal cavity width, in addition to the ratio of arch length to inter-molar width and the ratio of palatal vault depth to inter-molar width.Results: Upon comparing parameters between groups I and II: for both males and females in the normal erupting canine and the palatally impacted canine subgroups the only statistically significant difference was found in the inter-molar width and the arch length, while in the buccally impacted canine subgroups the palatal vault depth, the maxillary skeletal width and nasal cavity width showed statistically significant differences between the male and female groups. The ratio of arch length to inter-molar width showed no statistically significant difference between males and females in all sub-groups while the ratio of palatal vault depth to inter-molar width showed differences between males and females only in the buccal impaction subgroups.Conclusion: The male subjects of the palatally impacted canine have a wider and longer dental arch than the female subjects of the same subgroup while the male subjects of the buccally impacted canine subgroup have a deeper palatal vault, wider skeletal arch and nasal cavity width than the female subjects of the same subgroup. However, there was no difference between both sexes regarding the shape of the maxillary arch in all subgroups. .

ROSMARINUS OFFICINALIS PULPOTOMY FOR VITAL PRIMARY MOLARS: A CLINICAL AND RADIOGRAPHIC STUDY
Introduction: Pulpotomy is the most commonly attempted vital pulp therapy procedure to treat symptomless pulp exposures in primary teeth; however, the search for the ideal bactericidal and biocompatible medicament still continues despite the numerous clinical trials with different materials. Therefore, the aim of the present study was to clinically and radiographically evaluate the success rate of 6.25% aqueous extract of Rosmarinus officinalis in comparison to formecresol as a pulpotomy dressing medicament in vital primary molars. Methods: Twenty-five children aged 4-7 year with bilateral vital mandibular primary first molars indicated for pulpotomy were included in the present study. They were divided into two groups (A) and (B), 25 molars each; where each side of the patient received a different pulpotomy medicament; R-officinalis and formecresol. Both groups were assessed clinically and radiographically for six months. Results: After 6 months, the cumulative survival rates were 92.0% and 81.0% respectively for R-officinalis and formocresol with no statistically significant difference between the survival rates of the two medicaments. Clinical success for R-officinalis showed 96.0% while formocresol showed 88.0% clinical success. In addition, radiographic evaluation revealed higher mean inter-radicular bone density in the R-officinalis pulpotomy group when compared to the formocresol pulpotomy group. Conclusions: Based on the high cumulative clinical and radiographic survival results revealed in the present study, Rosmarinus officinalis can be considered a successful alternative pulpotomy medicament for formocresol with promising results in the treatment of vital primary molars.

IN VITRO ASSESSMENT OF WATER SORPTION, SOLUBILITY AND SURFACE ROUGHNESS OF COMPOMER AND GIOMER MATERIALS AFTER IMMERSION IN DIFFERENT BEVERAGES
Objective: The purpose of the present study is to assess the water sorption, solubility and surface roughness of compomer and giomer restorative materials after storage in different immersion media. Materials and Methods: Two resin-based restorative materials were selected for this study: Compomer (Twinky Star) and Giomer (Beautifil II). For water sorption and solubility, 6 disc-shaped specimens of each material were prepared according to manufacturers’ instruction. Measurements were done by weighing the samples before and after immersion in distilled water for 28 days and after desiccation. Values were statistically analyzed using student-t test (P-Value <0.05). For surface roughness, 18 disc-shaped specimens of each material were divided into three subgroups according to the immersion media; Mirinda orange, milk and distilled water as the control. Specimens were kept immersed for 28 days. Average baseline and after immersion surface roughness measurements were recorded using a 3D digital image processing technique. Values were statistically analyzed using One-way ANOVA (P-Value <0.05)Results: Twinky Star represented significant lower water sorption and solubility values (0.181 mg/mm3 and 0.179 mg/mm3) when compared to Beautifil II (0.208 mg/mm3 and 0.207 mg/mm3), respectively. No significant difference in the surface roughness values between both materials after the immersion in either distilled water, Mirinda orange or milk. Conclusions: The higher sorption and solubility of Beautifil II compared to Twinky Star might compromise its performance and longevity. Immersion of compomer and giomer in water and sugar-sweetened beverages may seriously reduce the durability of both materials . Mirinda orange could potentially erode both materials.
