AIMS Etoricoxib is a second-generation selective COX-2 inhibitor. There are a few researches investigating analgesic effect of Etoricoxib in dentistry. METHODS This randomized, double-blind, active-control study included sixty patients with clinical pulpal diagnosis of necrosis of the first mandibular molar and an associated periapical radiolucency who experienced severe pain (more than 60 ou...

The main reason for unfavourable outcome in endodontic treatment of mandibular incisor is the inability to detect the presence of second canal. Pain even after extirpation of complete pulp tissue from root canal of vital teeth is the main indication of hidden canals. The present case report is also on pain because of another neglected canal in all mandibular incisors in the same patient.

OBJECTIVES To assess the incidence of postoperative pain after single- and multi-visit endodontic treatment of teeth with vital and non-vital pulp. METHODS In total, 306 patients with teeth requiring endodontic treatment were identified and were included in this study. Two experienced clinicians treated the patients, who were randomly assigned to two groups. While the teeth of patients in gro...

INTRODUCTION The objective of the present study was to clinically compare the incidence of postoperative pain and the intake of analgesic medication (frequency and quantity) after endodontic treatment of posterior teeth using 2 reciprocating systems and a continuous rotary system. METHODS In a prospective randomized clinical study, 210 patients with vital teeth indicated for conventional endo...

The purpose of this prospective, randomized, blinded study was to determine the effect of apical trephination on postoperative pain and swelling in symptomatic necrotic teeth. Fifty emergency patients participated, and each had a clinical diagnosis of a symptomatic necrotic tooth with associated periapical radiolucency. After endodontic treatment, patients randomly received either an apical tre...

The benefits of using sodium hypochlorite (NaOCl) and ethylenediaminetetraacetic acid (EDTA) as endodontic irrigants, and calcium hydroxide as an inter-appointment medicament, are well known to dentists. Many steps undertaken during endodontic treatment and retreatment are rather mechanical in nature, and less attention is committed to understanding the biological issues underlying endodontic t...

Of all the procedural problems that can occur when practicing dentistry, endodontic file breakage is one dilemma that not only can lead to extreme stress for the clinician, but can cause great anxiety for the patient as well. Separated rotary nickel-titanium (NiTi) files can also pose an increased risk of post-endodontic complications. Understanding why and how endodontic file breakage occurs, ...
