Apical adaptation, sealing ability and push-out bond strength of five root-end filling materials.
This study compared the fluid filtration, adaptation to the root canal walls, and the push-out bond strength of two resin-based sealers and three calcium silicate-based retrograde filling materials. Fifty maxillary canines were shaped using manual instruments and the apical portion was sectioned. Retrograde cavities of 3-mm depth were prepared. The specimens were divided into five groups (n = 1...
متن کاملComparison of push-out bond strength of mineral trioxide aggregate and calcium enriched mixture cement as root end filling materials
BACKGROUND The purpose of this study was to compare the push-out bond strength of mineral trioxide aggregate (MTA) and calcium enriched mixture (CEM) as root end filling materials. MATERIALS AND METHODS A total of 40 root dentin slices (1 ± 0.2 mm) were prepared from freshly extracted human maxillary central teeth and their lumens were enlarged to 1.3 mm. The slices were randomly divided into...

GIC, microleakage, Miracle Mix, MTA, root-end filling. Abstract The main objective of a root end filling material is to provide an apical seal that prevents the movement of bacteria and the diffusion of bacterial products from the root canal system into periapical tissues. The aim of this study was to compare the microleakage of three root end filling materials Mineral trioxide aggregate (MTA),...
متن کاملA Comparative Investigation of Marginal Adaptation and Surface Defects of MTA and Root MTA as Two Root End Filling Materials
Introduction: This study was carried out to compare two retrograde filling materials entitled mineral trioxide aggregate (MTA) and Root MTA (RMTA) in regard to their marginal adaptation and surface defects. Method: In this study twenty extracted human teeth were used. In all teeth after cleaning and shaping, the root canals were obturated by gutta-percha and root canal sealer. After that in eac...
متن کاملIn vitro comparative evaluation of apical microleakage with three different root-end filling materials
Aim: To compare and evaluate the microleakage of three root end filling materials -Mineral Trioxide Aggregate (MTA), Biodentine and bioaggregate using vacuum dye penetration technique. Materials and methodology: Thirty extracted single rooted premolars were selected and decoronated. Root canals of teeth were cleaned, shaped using hand protaper file and obturated with corresponding gutta percha ...
