background and aims. a through knowledge of the root canal morphology is required for successful endodontic therapy. the aim of this study was to investigate the root and canal morphology of mandibular third molars in kerman, a province in southeast of iran. materials and methods. one-hundred-fifty extracted mandibular third molars were collected randomly from different dental clinics in kerman...

OBJECTIVES It is essential for clinicians to have adequate knowledge about root canal configurations; although its morphology varies largely in different ethnicities and even in different individuals with the same ethnic background. The current study aims to review the root canal configurations of mesiobuccal roots of maxillary first molars in an Iranian population based on different epidemiolo...

OBJECTIVE To analyse the influence of root canal instrumentation and obturation techniques on intra-operative pain experienced by patients during endodontic therapy. METHOD AND MATERIALS A descriptive cross-sectional study was carried out in Ponferrada and Sevilla, Spain, including 80 patients (46 men and 34 women), with ages ranged from 10 to 74 years, randomly recruited. Patient gender and ...

INTRODUCTION The main goal of endodontic therapy is to prevent or heal apical periodontitis. However, root canal anatomy might present a clinical challenge directly related to the treatment outcome. The purpose of this study was to review published literature related to root anatomy and root canal configuration of the permanent mandibular first molar. METHODS An exhaustive search was undertak...

Periradicular lesions are diseases either primarily or secondarily caused by microorganisms and therefore they must be prevented or treated accordingly. If the professional is well-versed in both preventing and eliminating the root canal infection, the success rate of endodontic therapy may exceed 90 percent. The present paper discusses theoretical and practical aspects of effective antimicrobi...

A detailed understanding of the complexity of root canal systems is imperative to ensure successful root canal therapy. The aim of this study was to evaluate the ability of an optical coherence tomography (OCT) system in imaging root canal walls after endodontic preparation and to correlate these images to histologic sections. Ten extracted mandibular incisors were prepared to size 50 with K-fi...

Root canal therapy (RCT) represents a standard of treatment that addresses infected pulp tissue in teeth and protects against future infection. RCT involves removing dental pulp comprising blood vessels and nerve tissue, decontaminating residually infected tissue through biomechanical instrumentation, and root canal obturation using a filler material to replace the space that was previously com...

The field of endodontics is devoted to the study and treatment of tissues inside (endo) the tooth (dontia). When a nerve within a tooth becomes necrotic andor infected, socalled root canal therapy might be considered. In this case, a dental practitioner cleans and widens the inner root canal system by chemical irrigation and mechanical instrumentation with respect to the original canal morpholo...

introduction: presence of surface defects in endodontic instruments can lead to unwanted complications such as instrument fracture and incomplete preparation of the canal. the current study was conducted to evaluate the effect of autoclave cycles on surface characteristics of s-file by scanning electron microscopy (sem). methods and materials: in this experimental study, 17 brand new s-files (#...
