Comparison of Two Reciprocating File Systems with Continuous Rotation System in Root Canal Preparation: A Randomized Clinical Control Trial.

Background: This study aimed to compare the degree of postoperative pain and analgesic consumption after the root canal procedure of mandibular premolar by utilizing two reciprocating and a continuous rotary file system and also evaluate the long-term periradicular status by periapical index (PAI) scores.

Materials And Methods: There were 84 patients, aged 18-55 years with mandibular premolar teeth recommended for root canal treatment who were treated under a predetermined protocol. Based on the instrumentation system used, all the patients were allocated randomly into three groups ( = 28): Group I: Reciprocating file no 1-ONE RECI, group II: Reciprocating file no 2-E3 AZURE, and Group III: Continuous rotary file-HERO GOLD, respectively.

Evaluation of Dissolution of Pulp by Sodium Hypochlorite when Mixed with Tetrasodic Etidronate and Disodic Ethylenediamine Tetraacetate under Controlled Flow.

Background: Sodium hypochlorite serves as the most efficient root canal irrigating fluid.

Objectives: This study's goal was to assess the replenished NaOCl's capacity to dissolve the tissue of pulp when combined with 9% tetrasodic etidronate (NaHEBP), 18% tetrasodic etidronate (NaHEBP), and 17% disodic ethylenediaminetetraacetate (NaEDTA) under continuous controlled administration.

Materials And Methods: Hundred and twenty complete undamaged teeth of the anterior mandible extracted due to periodontal problems within forty-eight hours were taken as a source of the pulp tissue.

Antimicrobial effect of herbal and conventional root canal endodontic irrigants against persistent pathogens.

Evaluation and comparison of natural products like triphala, eucalyptus and carvacol with conventional root canal irrigant such as sodium hypochlorite (NaOCL) and Chlorhexidine against persistent root canal pathogens like is of interest. Samples were taken both before irrigation as well as after irrigation. CFU was counted after the plates had been incubated overnight at temperature of 37°C overnight.

Racial predilection of C-shaped canal configuration in the mandibular second molar.

Aim: The purpose of this article is to determine the racial predilection of C-shaped canal configuration in a mandibular second molar.

Background: Unusual root canal anatomy always poses a diagnostic and treatment challenge. Identification of such variation is important for the success of root canal treatment outcome.
