NTRODUCTION The goals of root canal therapy are to remove infected and necrotic pulpal tissue remnants, shape the root canal system to facilitate irrigation and medication and adequate sealing using obturation materials. 1 Rotary instruments enhance the quality of obturation by providing conical shape to the root canal. Nickle titanium (NiTi) alloy instruments inherent flexibility that allows t...

BACKGROUND AND OBJECTIVE To date, many different materials have been proposed for root canal fillings, but gutta-percha (used with various types of sealers) has remained the material of choice for over a century. A new root canal obturation system, the Epiphany endodontic obturation system, has been developed to replace gutta-percha and traditional sealers for root canal obturation. The purpose...

OBJECTIVE To gather information on the materials and methods employed in root canal treatment by dentists in Turkey. METHODS A questionnaire was distributed to 1,527 dentists who attended the Turkish Dental Association Congress. Respondents were asked to choose one or more suitable answers for the questions. Data was gathered for demographic and professional information regarding stages, mate...

The aim of this study was to evaluate the accuracy of five electronic apex locators (EALs) in determining the working length (WL) of teeth after removal of the root canal obturation materials. A total of 32 extracted straight, single-rooted teeth were used. The actual canal length (AL) was determined and the WL was established by subtracting 0.5 mm from the AL. The root canals were instrumented...

This study used micro-CT to compare three obturation techniques with respect to void occurrence in canals filled with bioceramic sealer. Thirty extracted first mandibular premolars were prepared with a ProTaper Universal system and randomly allocated to three groups. Canals were obturated with gutta-percha and bioceramic root canal sealer, using either single-cone, lateral compaction, or Therma...

OBJECTIVE The objective of this study was to investigate the rise in temperature in root surfaces during and immediately after diode laser irradiation, to observe morphological changes of root canal wall after irradiation, and to evaluate the apical leakage after irradiation and obturation in vitro. BACKGROUND DATA There have been very few reports on root canal treatment by 980-nm wavelength ...

The success of root canal treatment is based on total elimination of root canal content, thorough cleaning, shaping and obturation of root canal system. Calcium hydroxide is recommended as intra-canal medicament because of its antibacterial properties, tissue dissolving ability, inhibition of tooth resorption and indication of tissue repair by hard tissue formation. Here we present a series of ...

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...
