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...
متن کاملEffect of thermoplastic filling techniques on the push-out strength of root sealing materials.
This study evaluates the effect of two thermoplastic obturation systems (MicroSeal and Obtura II) on bond strength of different sealers to intraradicular dentin. Sixty root canals of human canines were prepared using ProTaper rotary files (crown-down technique) and irrigated with 2.5% sodium hypochlorite and 17% EDTA. The root canals were filled by MicroSeal, Obtura II, or lateral compaction te...
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 کاملThe Effect Of Root Canal Irrigants On The Push –out Bond Strength Of Biodentine
Root perforation connect root canal spaces with periodontal tissues. The connection may occur as result of iatrogenic causes during root canal treatment (at the level of floor of the coronal cavity or at different levels of the root) or during prosthetic treatment of post canal trioxide aggregate(MTA), composite resin, glass ionomer cement and calcium hydroxide, most of these penetration. (1) A...
