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...

Introduction: Pulpectomy is a conservative treatment plan for primary necrotic teeth and Zinc Oxide Eugenol is still a good choice as root canal filling material but long term studies on poor prognosis molars are limited and almost contradictory. The purpose of this study is to evaluate the clinical and radiographical success rate of pulpectomy of necrotic primary molars using ZOE as the root c...

Aim: To compare the instrumentation time efficiency of rotary and hand instrumentation performed on necrotic human primary teeth. Methodology: Patients aged 4-7 years were enrolled, forty five teeth (19 maxillary and 26 mandibular teeth), which had a total of 102 canals and completely formed apices and of minimum 10 mm root length were selected. Of the 45 treated primary molars, 31 teeth were d...

INTRODUCTION The ideal endodontic treatment for the teeth with in complete root-ends and necrotic pulps may involve the use of material which forms an immediate apical barrier instead of long term calcium hydroxide therapy. Such procedure may lead us to a single appointment endodontic treatment. The purpose of the present study was to evaluate clinical and radiographic success rate in necrotic ...
