BACKGROUND To compare fracture resistance of endodontically treated teeth obturated with different resin-based adhesive sealers with a conventional obturation technique. MATERIALS AND METHODS A total of 60 Single canaled teeth were divided into five groups. The first group was taken as a negative control. The rest of the groups were shaped using ProFile rotary files (Dentsply Maillefer, Balla...

Introduction Dentinal canal walls are in direct contact with endodontic sealers prior to post space preparation and luting cements after post space preparation. This direct contact may affect the bond strength of intraradicular posts to root dentin. This study aimed to assess the effect of three different sealers on the bond strength of fiber posts to root dentin. Methods and Materials The ca...

INTRODUCTION The aim of this animal study was to evaluate the histological response of the new nano zinc-oxide eugenol (NZOE) sealer in comparison with Pulp Canal Sealer (ZOE based) and AH-26 (epoxy resin sealer). METHODS AND MATERIALS A total of 27 Wistar rats were used. Four polyethylene tubes were implanted in the back of each rat (three tubes containing the test materials and an empty tub...

This study evaluated the response of the subcutaneous connective tissue of BALB/c mice to root filling materials indicated for primary teeth: zinc oxide/eugenol cement (ZOE), Calen paste thickened with zinc oxide (Calen/ZO) and Sealapex sealer. The mice (n=102) received polyethylene tube implants with the materials, thereby forming 11 groups, as follows: I, II, III: Calen/ZO for 7, 21 and 63 da...

Objectives: This study aimed to assess tooth discoloration at 6 months following the use of 5% fluoride varnish (Duraflur), AH 26, zinc oxide eugenol (ZOE)-based sealer and mineral trioxide aggregate (MTA)-based sealer in extracted premolars. Materials and Methods: In this in vitro, experimental study, 75 freshly-extracted human premolars with completely formed roots underwent root canal treat...

Background: This study aims to evaluate fracture resistance on endodontically treated teeth when four unique sealers are being used. Materials and Methods: 75 human premolars (mandibular) recently extracted were utilised for this analysis. Random categorization of selected samples into 5 different groups depending the type sealer applied in canal. Group 1: RCTpex sealer, 2: MTA Fillapex 3: Seal...

introduction: optimal radiopacity is one of the properties required for a root canal sealer that helps the distinction between the sealer and surrounding anatomic structures and evaluation of the quality of root filling. so, the purpose of this study was to evaluate the radiopacity of six root canal sealers at different focal distances. materials and methods: in this in vitro study, six endodon...

Background and Purpose: Root canal therapy is the primary method for the treatment of an infected pulp in modern dentistry. The main aim of endodontic treatment is the elimination of bacteria and their products from infected root canals. In this study, we attempted to investigate the antimicrobial activity of three root canal sealers against oral pathogens. Materials and Methods: The antimic...

introduction: various materials and methods have been recommended for successful root canal obturation. the aim of this experimental in vitro study was to compare the sealing ability of three root canal sealers ah-26, glass ionomer cement (gic) and zinc oxide eugenol (zoe) in single gutta-percha obturating system. methods and materials: seventy extracted single-rooted human teeth were decoronat...
