introduction: this study aimed to compare the marginal adaptation of new bioceramic materials, endosequence root repair material (errm putty and errm paste), to that of mineral trioxide aggregate (mta) as root-end filling materials. materials and methods: thirty-six extracted human single-rooted teeth were prepared and obturated with gutta-percha and ah-26 sealer. the roots were resected 3 mm f...

Introduction: The purpose of this study was to test different sealer removal protocols following root canal filling before adhesive seal of access cavities. Material and methods: Forty single root teeth were selected for the study, prepared to size 60 taper .02, and filled with AH plus and a single gutta-percha cone size 55 taper .02. Excess sealer was removed with: ethanol-moisturised foam pel...

The purpose of this study was to observe the influence of coronal leakage on the behavior of periapical tissues after root canal filling and post space preparation. Forty root canals of dogs' teeth were instrumented and filled by the lateral condensation technique with gutta percha points and the cements Sealer 26 and Roth. After post space preparation, the remaining filling material was either...

INTRODUCTION The maximum removal of root canal filling material is essential for successful endodontic retreatment. The purpose of this study was to assess the efficacy of 2 reciprocating systems (Reciproc [VDW, Munich, Germany] and WaveOne [Dentsply Maillefer, Ballaigues, Switzerland]) compared with a nickel-titanium (NiTi) rotary system (ProTaper Universal Retreatment [Dentsply Maillefer]) in...

During endodontic treatment, it is important to create a fluid-tight seal in the access cavity in order to prevent marginal leakage and the ingress of oral fluids and microorganisms into the root canal. Nevertheless, temporary filling materials have received less attention than materials used for a permanent and prolonged use. However, they are an essential link in the chain that leads to disin...

The filling material remaining after post space preparation may not be enough to prevent the contamination of periapical tissues when the root canal is exposed to saliva. Thus, the purpose of this study was to evaluate leakage through three different materials used as barriers over the remaining filling. Thirty-two human premolars were selected for this study. Following the endodontic treatment...
