introduction : the aim of this in vitro study was to compare the effect of gates-glidden and peeso reamer drills on residual dentin thickness during post space preparation in order to discover which method has minimum root structure damage. materials and methods: thirty extracted human maxillary premolars with bifurcations at root middle were horizontally cut 15 mm coronal to the apical end aft...

introduction: various materials and methods have been recommended for successful root canal obturation. the aim of this experimental in vitro study was to compare the sealing ability of three root canal sealers ah-26, glass ionomer cement (gic) and zinc oxide eugenol (zoe) in single gutta-percha obturating system. methods and materials: seventy extracted single-rooted human teeth were decoronat...

The endodontic triad comprises of cleaning and shaping, disinfection and obturation. Success of root canal therapy is majorly achieved by proper cleaning and shaping. However, elimination of bacterial contaminants as well as necrotic debris of the canals requires the adjunctive use of irrigants. To achieve a satisfactory biological and mechanical preparation proper selection of endodontic instr...

abstract : dens invagination (di) is a developmental abnormality of teeth which frequently results in a complex internal anatomy of the root canal system. di type 3 is an anomaly characterized by infolding of enamel and dentin extending into the root apex. this may present difficulties when forming a diagnosis and treatment plan. many treatment modalities have been presented in case reports for...

Procedure Following nonsurgical root canal treatment, a post space is created in the root canal by careful removal of the coronal canal obturating material. A sufficient amount of material must be retained in the apical portion of the canal to maintain an adequate apical seal. A custom or proprietary post is fitted and cemented into the root canal for core retention. The post should be passivel...

OBJECTIVE To compare the technical quality of root canal obturation in relation to rotary and manual root canal preparation techniques. STUDY DESIGN Cross sectional, analytical study. PLACE AND DURATION OF STUDY The Aga Khan University Hospital Karachi from January till December 2011. METHODOLOGY Data was retrospectively retrieved by periapical radiographs of 60 root canal treated molars ...

introduction: the exact measurement of the root canal length is of great importance in root canal therapy. although, determination of the root canal length through radiography is the most common method, recently electronic apex locators are being used to determine working length and decrease the number of radiographs. the purpose of this study was to compare the accuracy of an electronic apex l...

INTRODUCTION This systematic review aimed to compare the effectiveness of sodium hypochlorite and chlorhexidine for root canal disinfection during root canal therapy. METHODS A literature search for clinical trials was made on the PubMed (MEDLINE), Web of Knowledge, SCOPUS, and Science Direct databases and in the reference lists of the identified articles up to January 2015. Quality assessmen...

Debridement of the root canal by instrumentation and irrigation is considered the most important single factor in the prevention and treatment of endodontic diseases. In clinical practice, instrumentation of the root canal(s) within the affected tooth is usually the most time consuming and technically demanding element of the treatment. The technical success of the treatment, as judged by the p...
