The role of obturation in root canal treatment, although considered secondary to debridement and disinfection, still remains a critical stage for a successful outcome. The aim of obturation is to seal the periradicular tissues from the residual microorganisms left in the root canal system after chemomechanical debridement. Obturation of the root canal space has been performed using various tech...

introduction: the efficacy of erbium-doped yttrium aluminum garnet (er:yag) laser for root debridement in comparison with curettes has been the subject of many recent investigations. considering the possibility of chemical and ultra-structural changes in root surfaces following laser irradiation, this study sought to assess the effects of scaling and root planing (srp) with curettes and er:yag ...

The apical delta is an intricate system within the root canal and incompletely debridement may affect the long-term prognosis of root canal therapy. The aim of the present study is to investigate the morphologic features of apical deltas in human teeth with micro-computed tomography (micro-CT) using a centreline-fitting algorithm. One hundred and thirty-six apical deltas were detected in 1400 t...

Introduction: Primary root canal treatment success depends on a number of variables, including debridement and disinfection of the root canal system to remove all bacteria and diseased pulpal and dentinal tissues. Complex root canal anatomy, such as concealed isthmuses, apical deltas and lateral canals, hinder this objective, making instrumentation of these regions nearly impossible. Recent adv...

Periodontal diseases are infectious diseases with a mixed microbial aetiology and marked inflammatory response leading to destruction of underlying tissue. Periodontal therapy aims to eliminate pathogens associated with the disease and attain periodontal health. Periodontitis is generally treated by nonsurgical mechanical debridement and regular periodontal maintenance care. Periodontal surgery...

introduction: this study aimed to compare the efficacy of mtad, glyde and edta in removing the post-preparation smear layer and debris produced in apical third of curved molar root canals. materials and methods: forty extracted human maxillary first molars with curved mesiobuccal canals (30˚-35˚), similar root lengths and morphologies were divided into 3 experimental groups (n=12) and one contr...

Root resection is the process by which one or more of the roots of a tooth are removed at the level of the furcation while leaving the crown and remaining roots in function [1]. Indications for root resection therapy include: teeth with periodontal problems, endodontic problems, root fractures, and prosthetic problems [2]. Vertical root fracture (VRF) is an untoward complication to root canal t...

resorption of tooth structures can occur as a result of physiological, pathological, and idiopathic factors. early diagnosis and appropriate treatment can prevent its serious complications. this case report presents surgical endodontic management of a trauma-induced perforating external root resorption, which was diagnosed with the help of cone beam computed tomography. following root canal tre...

Endodontic-periodontal lesion has been a diagnostic challenge. The present case report describes a case of localized primary periodontal lesion with secondary endodontic involvement in maxillary premolar. Its management was done by root canal therapy followed by periodontal regenerative procedure using Guided tissue regeneration technique.
