    Introduction
    Lichen planus is an inflammatory mucocutaneous disease that its etiology is still unknown. Various treatments are used to mitigate the pain, inflammation, and duration of lesions. Due to the lack of a definitive treatment and the side effects of current treatments, many efforts still have been making to find new treatments. As curcumin has been shown to have anti-inflammatory, analgesic, antimicrobial, and anti-tumor properties, this study was designed to study the effect of oral curcumin in treating oral lichen planus.
    Materials And Methods
    Ten patients with oral atrophic, erosive lichen planus participated in a pilot clinical trial intervention study. The patients were treated with 3 strips of Sina Curcumin capsules 80 mg, one capsule every day after breakfast for 4 weeks. The clinical appearance of lesions (based on the Thongprasom score) and pain severity (based on the Visual Analogue Score) were recorded before treatment and at the end of the first, second, and fourth weeks of the intervention.
    Results
    Using repeated measures analyses of variance, there were statistically significant differences in pain intensity (P = 0.043) and clinical appearance of oral lesions (P = 0.001) in patients treated with curcumin before and after treatment. At the end of the treatment period, pain was reduced in 50% of the patients and full recovery was observed in 10% of the patients. Clinical appearance of oral lesions improved in 80% of the patients.
    Conclusion
    Using a nanomicell formulation of oral curcumin could be considered as an alternative treatment for oral lichen planus. This drug is safe and has few side effects. However, it needs further studies with larger sample sizes and follow up periods.

    Introduction
    Nowadays, removable orthodontic appliances are widely used in the treatment of straightening teeth and guided the growth of the jaws. These devices have acrylic parts in which methyl methacrylate monomers are used and have been the subject of discussion in recent years as a cause of epithelial lesions in the oral cavity, and they are considered as one of the factors in mucosal allergies. This study evaluated the changes in oral epithelium, inflammation, and candida albicans in patients using removable orthodontic appliances.
    Materials And Methods
    In this cross-sectional study a total of 100 patients with removable orthodontic appliances was enrolled. Samples were collected from patients’ mucosa using swabs and pap smear and then they were stained by the use of hematoxylin and eosin (H&E). After data collection by SPSS 14.0, they were analyzed by Fisher’s exact test followed by the chi-square test at p
    Results
    There was no statistically significant relationship between the use of removable orthodontic appliances and candida albicans infection and inflammation.There was a significant relationship between these two in the both study group (p =0.000) and the control group (p = 0.003). There was no significant relationship between candida albicans and the time of dental appliance use (p=0.1). A significant relationship was observed between inflammation and the length of time of dental appliance use (p =0.028).
    Conclusion
    The results of this study showed that the inflammation and candida albicans infection in patients using removable orthodontic appliances were minimal and there were no dysplastic epithelium changes.

    Introduction
    The expansion of activities and performance areas of organizations, modern management issues mean that organizations are no longer satisfied with success in only a limited number of indicators. Mathematical models thus formed and gradually are developed for the assessment of organizations and provide the right tools. This study is conducted to provide a model for improving the quality of dental services in uncertain settings.
    Materials And Methods
    The study population in this study consists of two groups. The first group consisted of all the patients with at least one visit to the dental clinic of Guilan University of Medical Sciences in Rasht, 422 of whom were randomly selected through convenience sampling. These data were used for the IPA. The second group of experts consisted of 20 organizational directors and senior experts selected for the localization of the quality of services the dental clinic and the ISM. This applied descriptive-analytical study uses the Fuzzy Delphi method for selecting the components of the quality of services, the Importance-Performance Analysis (IPA) for identifying the strengths and weaknesses of these components, and the Interpretive-Structural Modeling (ISM) for improving the components of the quality of services by prioritizing the effectiveness of the factors.
    Results
    The dental clinic of Guilan University has to pay immediate attention to including providing services as promised, the delivery of services with care, timely responding, the personnel’s greater efforts for solving the patients’ problems, a consistent quality of services, the speed of services, in order to improve the quality of its services.
    Conclusion
    The ISM showed that there are six levels of influential factors, with the two variables of “providing services as promised” and “equipment and technology” acting as the cornerstone of the model that should be emphasized first and foremost for the system to begin functioning.

    Introduction
    The purpose of this study was to compare the antibacterial effect of sodium hypochlorite gel and solution on Enterococcus faecalis (E. faecalis). The main purpose of a root canal treatment is to eliminate the bacteria and their products. Sodium hypochlorite solution has excellent antibacterial properties, but also some negative features.
    Materials And Methods
    Fifty six single root straight canals were instrumented with Ni-Ti rotary files (ProTaper S1,S2,F1,F2,F3) and contaminated with E. faecalis. Then they were divided into four groups. Group A used sodium hypochlorite (NaOCl) 5.25% solution, Group B used NaOCl 5.25% gel, Group C used normal saline solution, and Group D used no irrigation. Microbiological samples were collected with sterile paper points. Statistical analysis was performed using MannWhitney U-test. The significance level was set to p
    Results
    In Groups A and B, no sign of E. faecalis presence was observed. Groups C
    and D showed presence of E. faecalis in all samples.
    Conclusion
    NaOCl 5.25% solution and gel showed the same effectiveness. Therefore, NaOCl 5.25% in the form of a gel can be recommended as a safe and controllable intracanal irrigant.

    Introduction
    Odontogenic tumors include a variety of lesions that are classified from hamartomas to benign and malignant neoplasms. Angiogenesis process helps neoplastic tissue to gain an adequate supply of oxygen and also to remove the waste products. Mean Vessel Density (MVD) evaluation is a common method for assessing angiogenesis by using different markers. To the best of our knowledge, there is no specific marker for angiogenesis evaluation, so the aim of this study is to determine the proper angiogenic
    marker.
    Materials And Methods
    In this cross sectional study, the MVD was assessed 45 cases totally; 15 cases in each group. Data were analyzed by using independent t-test and one-way ANOVA (P
    Results
    There are statistically significant differences between CD34 and CD105 (P=0.028), CD34 and VEGF (P=0.001) and, CD105 and VEGF (P=0.001). CD34 has the lowest sensitivity, and VEGF has the highest sensitivity among others.
    Conclusion
    The results suggest that VEGF could be a better marker for assessing angiogenic tissue.
