Measure and compare the Degree of Root Canal Transportation and Canal-centering ability of Twisted, ProTaper, and Conventional Stainless Steel K Files using Spiral Computed Tomography: An in vitro Study.

Aim: The aim of this study was to compare canal transportation and centering ability of Twisted files (TF) and ProTaper (PT) files with conventional stainless steel (SS) K files.

Materials And Methods: Thirty mandibular premolar teeth with root curvature of 25 to 35° were selected. The samples were randomly divided into three groups of 10 each according to the type of files used for instrumentation.

Efficacy of locally-delivered 1% metformin gel in the treatment of intrabony defects in patients with chronic periodontitis: a randomized, controlled clinical trial.

Objective: Metformin (MF), used for the treatment of type 2 diabetes mellitus, has shown to possess properties favoring osteoblastic proliferation. The present study was designed to investigate the effectiveness of MF 1% gel as an adjunct to scaling and root planing in the treatment of intrabony defects in patients with chronic periodontitis.

Methods: The study comprised 65 individuals divided into two groups: 1% MF with SRP and placebo gel with SRP.

The radix entomolaris and radix paramolaris: an endodontic challenge.

Success of endodontic treatment depends on the proper identi-fication of all the canals, thorough chemomechanical preparation followed by three-dimensional obturation with hermetic seal. Failure of any of these steps may occur due to unusual tooth morphology. Usually mandibular molars have two roots with three canals but in few teeth, the number of roots and canals vary.

Mandibular first molar with Vertucci type I canal confguration diagnosed with the help of cone beam computed tomography: a rare case report.

The knowledge of root canal morphology and the existing anatomical variations is essential for successful endodontic therapy. This report presents an extraordinary case of unusual tooth morphology involving the mandibular first molar with a single root and a single canal in a patient. Endodontic treatment of the affected tooth 36 was performed.
