Objectives. This retrospective clinical and radiographical study evaluated the 10-year outcome of one-visit endodontic treatment with gutta-percha and a methacrylate resin-based sealer. Methods. From an initial sample size of 180 patients, 89 patients with 175 root canals responded to a recall. Treatment outcome was based on predetermined clinical and radiographic criteria. Results. Root canals...

Procedure related factors define the success of root canal procedures in majority of the cases. While there are several guidelines available, the compliance rate is substantially low. This study evaluates the attitudes, materials and methods preferred in root canal therapy by dentists in Palestine. An online self-administered questionnaire was sent to 200 Palestinian dentists. The questionnaire...

The aim of this study was to investigate whether a final rinse with Endosolv R® solvent and ultrasound resulted in cleaner root canal walls during endodontic retreatment. A total of 56 extracted premolar teeth were manually instrumented using a step-back flare technique and filled with gutta-percha and AH Plus sealer. After 9 months, the canals were retreated by removing the gutta-percha and se...

Research in endodontics has for the most part been primarily focused on the development of the tools and materials most effective in facilitating root canal treatment. The majority of endodontic treatment principles originally evolved on the basis of trial and error; only recently have scientific methods been adopted that identify appropriate clinical strategies. The biological basis for the th...

OBJECTIVE This study evaluated the response of periapical tissues to the endodontic sealer Endométhasone in root canal fillings short of or beyond the apical foramen. MATERIAL AND METHODS Twenty root canals of premolars and incisors of 2 mongrel dogs were used. After coronal access and pulp extirpation, the canals were instrumented up to a size 55 K-file and the apical cemental barrier was pe...

INTRODUCTION The aim of this in vitro study was to compare the efficacy of two retreatment rotary systems in removal of gutta-percha (GP) and sealer from the root canal walls with and without use of solvent. MATERIALS AND METHODS Sixty single-canalled distal roots of mandibular molars were prepared and root filled with gutta-percha and AH26. Each canal was randomly allocated to receive one of...

AIM This study describes a clinical case of type III dens invaginatus with an extensive periradicular lesion treated successfully. BACKGROUND Dens invaginatus is a maldevelopment of the dental germ which occurs as a result of the invagination of the enamel organ. These cases may present difficulties with respect to its diagnosis and treatment because of canal morphology. The success of endodo...

BACKGROUND The aim of the present study was to compare in vitro the antimicrobial activity of different root canal sealers against Enterococcus faecalis, prior and subsequent to setting. MATERIAL AND METHODS Agar diffusion test (ADT) was used for evaluating the antibacterial activity of non-set sealer while the direct contact test (DCT) was used for after setting. RESULTS ADT: Except for To...

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...
