[ 1 ] - مقایسه تاثیر دو سیستم One-ShapeوXp-endo-Shaperبرمیزان دبری خروجی- مطالعه آزمایشگاهی
خلاصه: سابقه و هدف: خروج دبری از اپکس از عوامل بروز flare up (تورم، درد یا ترکیبی از هر دو) می‌باشد. تحقیقات مختلفی در رابطه با میزان خروج دبری در سیستم‌ها و فایل‌های مختلف صورت گرفته است، ولی تحقیقی در مورد مقایسه دو سیستم One Shape و Xp-endo–Shaper در کانال‌های خمیده گزارش نشده است. بنابراین تحقیق حاضر با هدف تعیین میزان خروج دبری از فورامن اپیکال به دنبال آماده‌سازی با دو سیستم چرخشی One ...
[ 2 ] - مقایسه سه ماده MTA ،CEM و GeriStore برمیزان کمی چسبندگی سلولهای فیبروبلاست لثه ای
خلاصه : سابقه و هدف: کیفیت و کمیت سلولهای چسبیده به مواد پرکننده انتهای ریشه از موارد تعیین کننده سازگاری نسجی مواد می باشد. این تحقیق با هدف مقایسه میزان کمی چسبندگی سلولهای فیبرو بلاست لثه ای به سه ماده ترمیمی رتروگرید CEM GeriStore و MTA انجام شد. مواد و روش‌ها: در این مطالعه تجربی-آزمایشگاهی تعداد 8 عدد دیسک از هر ماده مورد آزمایش تهیه گردید و د ر داخل محیط کشت سلولی حاوی سلولهای فیبروب...
[ 3 ] - Repair of a furcation perforation with mineral trioxide aggregate: A case report with 6 year follow-ups
Perforations might occur due to carious lesions, tooth resorption or they might be iatrogenic during endodontic treatment or in most cases they might occur during post space preparation. CASE REPORT: A 31-year-old female patient presented with a complaint of chronic pain on tooth #30 during last 6 months and sensitive to bite since a few days ago.

[ 5 ] - Ex Vivo Comparison of the Discoloration Potential of Two Endodontic Sealers in Human Incisors
Background and Aim: Tooth discoloration induced by endodontic materials is a common finding which can impair the aesthetic outcome. The aim of this study was to compare the coronal discoloration induced by Well-Root ST and AH26 root canal sealers by using the Easyshade® colorimeter. Materials and Methods: Forty-five intact maxillary central incisors were involved in this experimental study. Th...
[ 6 ] - Onset of action and duration of efficacy of inferior alveolar nerve block versus single lingual subperi-osteal injection of 4% articaine in mandibular second molars: A randomized clinical trial
Background and Aim: Achieving adequate pulpal anesthesia could be challenging in mandibular molars. There are some disagreements about the success rate of local infiltration anesthesia with articaine as primary injection. Therefore, the aim of this study was to assess the efficacy of 4% articaine lingual subperiosteal injection as the primary injection for permanent mandibular second molars in ...
[ 7 ] - Efficacy of XP-Endo Finisher R File in the Removal of Gutta-percha residue after root canal retreatment: an experimental study
Background and Aim: Complete removal of gutta-percha from the root canal system and its remnants is a challenge in endodontic retreatment. This ex-vivo study aimed to assess the efficacy of XP-Endo Finisher R (XEFR) in removing root filling remnants from straight canals of mandibular premolars in root canal retreatment. Materials and Methods: In this ex-vivo study, 30 single-rooted mandib...
