The dental lasers of today have benefited from field of quantum mechanics, initially formulated during the early 1900s by Danish physicist Bohr. The first laser use in endodontics was reported by Weichman & Johnson (1971) who attempted to seal the apical foramen in vitro by means of a high power-infrared (CO2) laser. In May 1990, Myers and Myers developed the first specialized dental laser (pul...

Sodium hypochlorite (NaOCl) in various concentrations is the most widely used endodontic irrigant, but it can be an irritant to vital tissues. There are several reports about the complications of irrigation with NaOCl during root canal therapy. Most of the complications are the result of accidental extrusion of the solution from the apical foramen or accessory canals or perforations into the pe...

Introduction: Knowledge of the internal anatomy of the tooth, apical foramen (AF) and mental foramen (MF) is considered a basic prerequisite before root canal surgical and non-surgical treatments. The aim this study is evaluation the distance and situation of AF & MF to anatomic apex of mandibular  premolar. Materials & Methods: In this cross-sectional study, CBCT images of mandibular p...

This article presents the procedures that must be considered for periapical cyst repair after nonsurgical endodontic treatment. The case of a periapical cyst associated to the left maxillary lateral incisor is reported. Nonsurgical root canal therapy was performed and lesion healing was confirmed radiographically after 24 months. Differential diagnosis, endodontic infection control, apical fora...

Objectives The aim of the study is to define the relationship between the apical preparation diameter and the apical sealing ability to highlight the importance of the preservation of the diameter and the original position of the apical foramen. Materials and Methods 50 extracted maxillary incisors were randomly allocated into three groups of 15 teeth each (n = 15) according to the apical pre...

This study evaluated the accuracy of three electronic apex locators (Root ZX, Novapex, and Justy II) in root canal length determinations using different apical file sizes, considering the apical constriction (AC) and the major foramen (MF) as anatomic references. The diameter of the apical foramina of 40 single-rooted teeth was determined by direct visual measurement and the master apical file ...

in order to deermine the effect of root canal cealer on microleakage of obturated root canal by lateral condensation technique(LCT) with and without tug-back(TB).seventy exteracted single root canal teeth were examined.after preparation of root canal with step-back technique,teeth were divided to six groups as follows:5 teeth as positive control group that obturated by LCT with gutta-perch itho...
