INTRODUCTION This study examined the effect of a new bioactive dentin substitute material (Biodentine) on the viability of human gingival fibroblasts. METHODS Biodentine, White ProRoot mineral trioxide aggregate (MTA), and glass ionomer cement were evaluated. Human gingival fibroblasts were incubated for 1, 3, and 7 days both in the extracts from immersion of set materials in culture medium a...

Background: Surgical endodontic therapy is the prescribed treatment of choice whenever the non-surgical options fail which includes the use of a root end filling material. E. faecalis is the most prevalent organism associated with the treatment failed cases Aim: The purpose of the present study was to evaluate and compare the antimicrobial efficacy of Biodentine and MTA as root end filling mate...

introduction : the purpose of this study was to assess the effect of different irrigation protocols for smear layer removal on the bond strength of endosequence bc sealer, a new bioceramic sealer, to root canal dentin. materials and methods : the middle third of forty-four extracted human teeth were sectioned horizontally to obtain 128 dentin disks. after standardization of canal spaces, dentin...

The greatest threats to developing teeth are dental caries and traumatic injuries. The primary goal of all restorative treatment is to maintain pulp vitality so that normal root development or apexogenesis can occur. If pulpal exposure occurs, then a pulpotomy procedure aims to preserve pulp vitality to allow for normal root development. Historically, calcium hydroxide has been the material of ...

INTRODUCTION On the basis of many clinical observations, some calcium silicate-based cements have a high potential for staining tooth tissue. This feature greatly limits the use of those cements, particularly for anterior teeth. This review aimed to provide a systematic evaluation of published in vitro studies to determine the effect of different calcium silicate-based cements on dental tissue ...

INTRODUCTION Bioactive endodontic sealers have been developed to improve the quality of root canal obturation. EndoSequence Bioceramic (BC) Sealer is amongst calcium silicate-based materials recently developed for permanent root canal filling. The objective of this study was to evaluate the bioactivity of BC Sealer and its micro push-out bond strength to dentin compared to AH-Plus (AH) sealer. ...

internal resorption is rare in permanent teeth. treatment is usually performed through warm gutta-percha technique. if the resorptive process perforates the root, treatment may be more difficult and is usually performed via surgical approach. non-surgical repair of a perforating internal root resorption with mta was conducted in this case. before repairing the resorption, a master gutta-percha ...

The aim of this study was to compare the vertical fracture resistance of roots obturated with different root canal filling materials and sealers. Crowns of 55 extracted mandibular premolar teeth were removed to provide root lengths of 13 mm. Five roots were saved as negative control group (canals unprepared and unfilled). Fifty root canals were instrumented and then five roots were saved as pos...

INTRODUCTION The advantages of aortic valve and aortic root reconstructive surgery include the provision of natural postoperative valve hemodynamics and the avoidance of prosthetic valve-related complications. A systematic approach based on functional classification of aortic regurgitation allows standardization and reproducibility. Its potential applicability, however, is limited by the relati...
