زمینه و هدف: اخیراً با در نظر گرفتن مزایا و معایب (mineral trioxide aggregate) mta ماده ای به نام calcium enriched mixture (cem) cement ابداع شده است. هدف از انجام این مطالعه مقایسه میزان ریزنشت حفرات انتهای ریشه آماده شده با اولتراسونیک یا لیزر er,cr:ysgg و پر شده توسط mta یا cem cement بود.
Condensation Pressure Effect on Microleakage of Mineral Trioxide Aggregate Seyed Mohsen Jalalzade 2Elham Khoshbin *3Seyed Abdolkarim Tabatabaei Endodontist, Mashhad, Iran. Assistant professor of endodontic department, Dental school, Hamedan University of medical science, Hamedan, Iran Post graduate student of pediatric dentistry department, Dental school, Shahid Beheshti Universi...
introduction: one of the hypotheses regarding the calcification induction by mineral trioxide aggregate (mta) is the involvement of transforming growth factor-beta (tgf- β ) super family. calcium-enriched mixture (cem) cement is one of the endodontic biomaterials with clinical applications similar to mta. the aim of the present in vitro study was to compare the induction of bone morphogenic pro...
مقدمه: استئوبلاستها و سلول های لیگامان پریودنتال سلول های اصلی برای ترمیم زخم های پس از قطع انتهای ریشه هستند. تداخل بین سلول های استئوبلاست بصورت تماس مستقیم با مواد پرکننده انتهای ریشه نقش حیاتی در ترمیم زخم های جراحی دارند. هدف از این مطالعه ارزیابی مورفولوژی و چسبندگی سلولهای استئوبلاست انسان در مجاورت MTA تیره، MTA سفید و IRM بعنوان مواد پرکننده انتهای ریشه توسط اسکن میکروسکپ الکترونی بود...
introduction: the purpose of this study was to compare the push-out bond strength of white proroot mineral trioxide aggregate (mta), biodentine, calcium-enriched mixture (cem) cement and endosequence root repair material (errm) putty after exposure to blood. methods and materials: a total of 96 root dentin slices with a standardized thickness of 1.00±0.05 mm and standardized canal spaces were r...
introduction: mineral trioxide aggregate (mta) mixed with normal saline has short working time, delayed setting time, and poor consistency when used as an apical plug. a preliminary study suggested that substituting normal saline with ky jelly or 5% calcium chloride (cacl 2 ) as a vehicle expedites the setting time of mta. the present in vitro study compared the microleakage of proroot mta mixe...
introduction : recent investigations have attempted to improve regenerative endodontics with the help of stem cell therapy. in vitro studies have shown the ability of different agents to stimulate the differentiation of dental pulp stem cells (dpsc) into odontoblast-like cells. a combination of dexamethasone, β-glycerophosphate and vitamin d has been proven to induce a successful differentiatio...
introduction: this case report describes apexogenesis treatment of three molar teeth of an 8-year-old boy using three different pulpotomy agents. methods: pulpotomy was performed on decayed immature molar teeth with established irreversible pulpitis and the remaining pulp was capped with either zinc oxide eugenol, proroot mineral trioxide aggregate or calcium-enriched mixture (cem) cement. teet...
introduction : to evaluate the clinical and radiographic outcomes of pulpotomy treatment with mineral trioxide aggregate (mta) in symptomatic mature permanent teeth with carious exposure. materials and methods: ten patients aged 27-54 years presented with 11 symptomatic permanent teeth ( n =11). each offending carious tooth was clinically and radiographically determined. we removed caries as co...
