Background and Aim: Recurrent aphthous stomatitis (RAS) has a high prevalence and there is no cure for and all current treatments are symptomatic. One of the drugs prescribed for the symptomatic treatment of these lesions is Diphenhydramine. Its side effects are seen and it is contraindicated in some cases. In this study the effect of soluble plant based oral Rose drop in aphthous ulcers compared with Diphenhydramine.
Materials & Methods: This Double blind clinical trial study were performed with a sample of 100 people (in two groups of 50 people) and two groups were matched according to sex, age, education level, location and number of aphthous lesions, duration of lesions, recent trauma into the oral mucosa, smoking, and burning and pain severity before treatment. Randomly, one group treated with diphenhydramine and the other group was treated with plant drops of rose extracts. Patients' pain severity at the second, fourth and seventh days after treatment were compared. Collected data were analyzed using Mann-U-Whitney.
Results: The severity of pain and burning in the Rose extract treated group in the second, fourth, and seventh days after treatment was respectively, 6.28 ± 1.24, 4.88 ± 1.42, 3.20 ± 1.55.and for the diphenhydramine group in second , fourth and seventh days after treatment was ، 24/1±42/6 . 67/1±4/3 ، 29/1±04/5 These amounts were not significantly different (P> 0.05).
Conclusions: It seems use of two drugs oral rose extract and diphenhydramine had the same therapeutic effects on oral aphthous lesions, and according to the more benefits of rose extract and the less side effect, the use of this drug is recommended to improve oral aphthous lesions.

Background and Aim: The purpose of this study was to evaluate residual dentin thickness of the root and the area of the canal lumen in the coronal region of the mesiobuccal and mesiolingual canals of the lower first molars after canal preparation with the common method of using hand files and Gates Glidden drills or ProTaper rotary files, by Spiral Ct-Scan.
Materials and Methods: In this experimental randomized controlled study, primary images of mesial canals of 12 lower first mandibular molars were taken using Spiral CT-scan. The dentin thickness at the areas of 1,3 and 5 millimeter sections and lumen area at the same sections were measured. Samples were randomly divided into two groups. In one group the mesibuccal canal was prepared with ProTaper system and the mesiolingual canal with hand files and Gates Glidden drills. In the second group vice versa. Afterwards, images were taken from the same sections and Measurements were performed. The results were assessed using independent- T test.
Results: In this study the remaining dentin thickness at the danger zone (distolingual/distobuccal) at the 5 millimeter section was significantly larger in the canals that were prepared with the ProTaper system than those prepared with hand instrumentation and Gates Glidden drills (P=0.04). Moreover, there was a statistical difference in the amount of dentin removed at the one millimeter sections on the distal areas (P=0.025) and danger zones (P=0.027) and in the 3 millimeter section of the danger zone (P=0.002). There was no statistically significant difference in the prepared lumen area between the two different approaches (p>0.05).
Conclusion: According to the results of this study ProTaper system is a safer method compared to hand instrumentation and Gates Glidden drills, to be used for preparation of mesial canals of the lower first molars with 10-35 degrees and approximately equal radius.

Background and Aim: Sandwich technique is one of the most common methods in dentistry in which resin-modified glass ionomers due to advantages such as fluoride release and adhesion to tooth structure are used with composite restorations. The aim of this study is assessment of shear bond strength between resin modified glassionomer and composite using different bonding agents.
Material and Method: In this invitro study, 60 resin modified glass ionomer samples (GC FUJI 2LC) were prepared. .In the first group, without the use of bonding agent and in other two groups with the use of bonding agents( SE bond and S3 bond) composite adhered to glass ionomer.After placing the samples in distilled water in incubator with temperature 37/5° C for one week, shear bond strength of samples was measured by the universal machine test . One way analysis of variance and Tukey test were used for analyzing the data and comparison between groups.
Results: The maximum amount of the bond strength was for specimens bonded with SEbond(13/09 Mpa) and the lowest amount was in control group(5/3 Mpa) . The mean shear bond strength was significantly different between the four groups.(p<0.05)
Conclusion: The maximum shear bond strength between resin-modified glass ionomer and composite resin was related to SE bond therefore using of this bonding agent in sandwich technique is recommended.

Background and Aim: Given that the effectiveness of mint on a plaque. The aim of this study was to compare the impact of mint mouthwash with chlorhexidine on persons volunteered to be studied Islamic Azad University in Tehran.
Materials and Methods: The clinical trial cross over- double blind clinical trial was carried out. Initial plaque was recorded, and the samples randomly divided into two groups and they asked to rinse their mouthwash twice a day for 4 weeks. After 2 weeks wash out period, the groups were rotated and they used different mouthwash as the same methods.T he plaque and pigments and acceptance of person were recorded and Mann-U-Whitney test was used.
Results: The stain of those who had used chlorhexidine was (6.05 ± 1.16), and those who used mint mouthwash was (2.18±0.83) (P <0.001). In the people who used Mint Mouthwash, the plaque score was (1.17± 0. 24) and those who used chlorhexidine was (0.86 + 0.17).( P <0.001). The whole people who used mint mouthwash did not feel any flavor in their mouth. but the whole people who used chlorhexidine felt bad feeling in their mouth. (P <0.001).%84(21 cases) of patients who received chlorhexidine felt burning sensation ,in%12(3 cases) of people who used mint mouthwash were reported burning sensation of the mouth. (P <0.001). In %96(26 cases) of those who received chlorhexidine had sense of foul odor and in %4 people who have used mint mouthwash foul odor in the mouth were reported. (P <0.001)
Conclusions: It seems, Chlorhexidine mouthwash in reducing microbial plaque is better than mint mouthwash but regarding feeling flavor, no burning sensation and less staining, mint mouthwash had better efficacy.

Background & aim: Class II subdivision malocclusion, characterized by asymmetry of occlusion has long been a challenge for dentists. The etiology basis of the Class II subdivision has not been resolved, even today. Some studies have shown that the unilateral distal positioning of the mandibular first molars was the primary etiologic factor in class II side. Few other studies, however, found that there was a tendency for skeletal asymmetry. The aim of this study was to determine the Relation of dentoalveolar and skeletal measurements with asymmetric occlusion in class II subdivision malocclusion and comparing it with normal occlusion at year of 92-93.
Material & Method: In this case-control study 60 panoramic,belonged to 30 control with normal occlusion & 30 Class II subdivision patients after matching , were selected. 1st, 2nd and 3rd molar and axial angulations and 3rd molar space were assessed. Third molar space was adjusted for the magnification factor. The final data were statistically analyzed by Mann-U-Whitney test on 95% level of confidence
Results: Statistical analysis indicated significant statistical differences between one of these dentoalveolar parameters (differences between axial inclination of first molar in two sides of mandible in case and control group.)
Conclusion: Class II subdivision asymmetric malocclusion is due to dentoalveolar Factors.

Background and Aim
Local antibacterial agents containing chlorhexidine (CHX) are used as an adjunct to conventional treatment in periodontal patients. In this study, a sustained release, xanthan- based CHX gel was used for non surgical treatment in moderate to advanced periodontitis.
Methods and Materials
In this randomized controlled split-mouth clinical trial, 40 periodontal pockets with probing pocket depth > 5 mm were selected and randomly assigned to the case and control groups. Scaling and root planing (SRP) were performed thoroughly at all sites. Then, chlorhexidine gel and placebo gel were applied subgingivally in test and control sites, respectively. The gels’ application was done two times with one week interval. The clinical parameters including plaque index (PI), papillary bleeding index (PBI), pocket depth (PD) and clinical attachment level (CAL) were evaluated at baseline, after 1 and 3 months. Data analysis was performed using U Mann-Whitney and Friedman tests.
Results
Statistically significant improvements were observed in PBI, CAL and PD parameters following treatment in each group after 1 and 3 months. Comparison between the two treatment groups showed no significant differences in clinical parameters at any time point.
Conclusion
According to the findings of this study, adjunctive subgingival application of chlorhexidine gel did not improve clinical parameters significantly compared to scaling and root planing treatment in moderate-to-severe chronic periodontitis.

Background and aim: Lichen planus is a common inflammatory muco-cutaneous disease. The main treatment of lichen planus is topical use of corticosteroids. However, long-term application of them could have adverse reactions and also recurrence and resistance to treatment may occur. Anti-oxidants and biologics have been introduced as alternative treatments. In this review article, therapeutic applications of these two groups in oral lichen planus are discussed.
Material and Methods: In this review, 46 articles were included in the study through the electronic search and after evaluation of the titles and abstracts.
Results: Anti-oxidants and biologics both are increasingly in the center of attention. Retinoids have been introduced for a long time before. Generally, the results have showed efficacy of most of them in the treatment of lichen planus. However, further studies are required. Biologics are considered for specifically targeted treatment recently and they could be an appropriate alternative for corticosteroids but biologics still are in the advent of their path and further investigations are needed for their function evaluation.
Conclusion: It seems that Anti-oxidants and biologics could be an appropriate alternatives for oral lichen planus.
