The main objectives of root canal treatment are thorough shaping and cleaning of all pulp spaces and its complete obturation with an inert filling material. The presence of untreated canal may be a reason for failure of endodontic therapy. To achieve satisfactory root canal therapy, a proper and in-depth knowledge of complex and abnormal root canal morphology is essential.

Introduction Pain control following root canal therapy is a challenging issue in dentistry. This double-blind study aimed to compare the effectiveness of Celebrex and celecoxib used to control post-endodontic pain. Material and Methods In this randomized, double-blind study, 43 patients with symptomatic teeth were selected. The subjects gave their consent for a prophylactic oral administrati...

INTRODUCTION It is very important to obtain a tight seal in obturated root canal, making it necessary to conduct clinical or laboratory studies on the sealability of endodontic materials. Different methodologies have been historically used to assess microleakage of different endodontic materials. The aim of the present study was to comprehensively review different material testing methods used ...

Periradicular surgery has become an established treatment option in endodontic surgery. The major objective of this surgery is to obtain periradicular tissue regeneration, including the formation of a new attachment apparatus, by exclusion of any potentially noxious agent within the physical confines of the affected root. However, in a substantial number of cases, the endodontic lesion has a co...

The main objective of endodontic therapy is the thorough mechanical and chemical cleansing of the entire root canal system and its complete obturation with an inert filling material. Failure to find and fill a canal contributes toward the failure of endodontic therapy .The root canal anatomy of mandibular first molars is complex. Studies of the morphologic structure of root canal systems hav...

introduction: this in vitro study aims to evaluate the coronal and apical sealing ability of gutta-percha (gp) root filling used with either mineral trioxide aggregate (mta), new endodontic cement (nec) or ah26 as filler/sealers. materials and methods: forty eight single-rooted extracted teeth were selected, decoronated and then instrumented. samples were randomly divided into three experimenta...

With growing concern over bacterial resistance, the identification of new antimicrobial means is paramount. In the oral cavity microorganisms are essential to the development of periradicular diseases and are the major causative factors associated with endodontic treatment failure. As quaternary ammonium compounds have the ability to kill a wide array of bacteria through electrostatic interacti...

Introduction. Endodontic instruments during root canal treatment come into contact with dentinal debris, irrigation solutions and medication agents, which reminants should be eliminated before sterilization. The aim of the study was to verify effectiveness different cleaning methods for removing calcium hydroxide paste residues from surfaces working parts hand instruments, as well propose an ef...

BACKGROUND Irrigation of the root canal system is an essential step in the endodontic treatment. The aim of this article is to introduce continuous apical negative-pressure ultrasonic irrigation (CANUI), a new irrigation concept, and compare the characteristics of this new technique with current devices for activating the irrigant. MATERIAL AND METHODS CANUI is designed for cleaning and disin...
