Prevalence of C-shaped canals in mandibular second and third molars in a central India population: A cone beam computed tomography analysis.

Introduction: To evaluate the prevalence of C-shaped root canals in mandibular molars using cone beam computed tomography (CBCT) in a subpopulation of Central India.

Materials And Methods: CBCT scans of patients from diagnostic imaging center were selected in accordance with the criteria given by Fan . (2004) for C-shaped canals.

Effect of single dose pretreatment analgesia with three different analgesics on postoperative endodontic pain: A randomized clinical trial.

Introduction: One of the aims of root canal treatment is to prevent or eliminate pain. Postoperative endodontic pain control continues to be a significant challenge.

Aim: To compare and evaluate the effect of single oral dose of 100 mg of tapentadol, 400 mg of etodolac, or 10 mg of ketorolac as a pretreatment analgesic for the prevention and control of postoperative endodontic pain in patients with symptomatic irreversible pulpitis.
