introduction: the purpose of this in vitro study was to investigate the influence of 5.25% sodium hypochlorite (naocl) and 0.12% chlorhexidine gluconate (chx) use separately and combined as endodontic irrigants on the apical sealing ability of two endodontic sealers. materials and methods: eighty-six extracted maxillary central incisor teeth were used. the teeth were decoronated at the cej, acc...
introduction: recently, attention has been drawn to the influence of smear layer removal on apical seal, and the relation of root canal filling material with canal wall surface in the presence and absence of the smear layer. the purpose of this study was to evaluate the influence of the smear layer removal on the apical sealing ability of ah26 sealer. materials and methods: forty extracted huma...
مقدمه: برای جلوگیری از رشد باکتری های باقی مانده پیشنهاد شده که مواد پرکننده کانال و سیلرها خصوصیت ضد میکروبی داشته باشند. هدف از این مطالعه بررسی اثر ضد باکتری مخلوط ah26 با دو نوع آنتی بیوتیک متفاوت بر انتروکوکوس فکالیس بود. مواد و روش ها: در این مطالعه آزمایشگاهی، خاصیت ضد میکروبی آموکسی سیلین و مینوسیکلین که به صورت جداگانه به سیلر ah26 اضافه شده بودند بر روی انتروکوکوس فکالیس مورد بررسی قر...
مقدمه:در درمان ریشه، سیل کردن سیستم کانال ریشه پس از مرحله پاکسازی و شکل دهی، ضروری و واجب است. با توجه به معیارهای Grossman ثبات ابعادی از جمله ملزومات یک سیلر است. هدف این مطالعه، مقایسه سیلر نانو زینک اکساید اوژنول با پالپ دنت و AH26 از نظر ثبات ابعادی بود. موا...
introduction: the purpose of this ex vivo study was to determine the releasing characteristics and doxycycline dentinal diffusion of ah26 sealer-doxycycline combination from apical 3mm of tooth root and apical foramen . materials & methods: one-hundred and two recently extracted single-rooted human teeth were decoronated and prepared with #3 and #4 gates-glidden drills and rotary mtwo files. sm...

The purpose of this study was to evaluate the influence of the smear layer removal on the apical sealing ability of AH26 sealer. MATERIALS AND METHODS Forty extracted huma...
Background and Aim: Complete obturation of the prepared root canal is an essential step in endodontic treatment. Combination of gutta-percha and a sealer is widely used in clinical practice for root canal obturation, thus microleakage studies on sealing properties of these materials constitute an important part of endodontic researches. The aim of this study was to evaluate the microleakage of ...
introduction: intrinsic tooth discolorations after endodontic treatment are principally attributed to the composition of necrotic pulp tissue, hemorrhage within the pulp cavity, endodontic medicaments and/or filling materials. residual sealer left in pulp chamber after obturation can cause discoloration. the objective of this in vitro study was to evaluate coronal discoloration created by ah26 ...
Introduction: This interventional in-vitro study aimed to evaluate the antimicrobial activity of a new Nano Zinc OxideEugenol (NZOE) sealer in comparison with AH26 and Pulpdent common root canal sealers against endodontic pathogens. Methods: The antimicrobial efficacy of three sealers(NZOE, AH26 and Pulpdent) against Enterococcus faecalis (ATCC 29212), Escherichia coli (ATCC 25922), Streptococ...
