Background and Aim: The main goal of root canal treatment is to prevent or treat apical periodontitis. The aim of the present study was to assess the coronal restoration status, root canal filling quality, periapical health condition, and related factors in endodontically treated teeth at the Dental Faculty of Islamic Azad University of Medical Sciences, Tehran, Iran, in 2011-12. Materials and...

AIM To compare the cleaning effectiveness and shaping ability of SafeSider, ProTaper Universal and Lightspeed rotary instruments during the preparation of curved root canals in extracted human teeth. MATERIALS AND METHODS A total of 63 roots with curved root canals were divided into three groups. Canals were prepared using SafeSider, ProTaper Universal or Lightspeed LSX. Using pre- and post-i...

Complex and unusual root canal morphology is an often occurring phenomenon. Understanding the unusual root canal morphology contributes to success in endodontic treatment. One such variant root canal morphology is the 'S' shaped or bayonet shaped root canal. This case report discusses endodontic treatment of a maxillary second premolar with an 'S' shaped root canal.

the success of endodontic therapy requires knowledge of the internal and external dental anatomy and its variations in presentation. this case report involves endodontic treatment of a traumatized maxillary central incisor with two separate roots.

Background The treatment of root canal infection consists of eradicating microbes from the root canal and preventing re infection by root filling. Though the existing intra canal medicaments fight against multidrug resistant microbes in root canal, still re-infections occurs. The objective of this study is to synthesize new b-lactam compounds and evaluate their antimicrobial activity to treat r...

OBJECTIVE The aim of the present study is to assess the root and root canal morphology of maxillary and mandibular premolars in a Turkish population by using cone beam computed tomography (CBCT). MATERIALS AND METHODS In this study, CBCT images of 2134 premolars (987 maxillary, 1147 mandibular) were obtained from 404 patients. Details of gender, age, number of roots and canals, and canal conf...

Aim. To determine the root and canal morphology of permanent maxillary first molars in a Sri Lankan population with special emphasis on the presence of a second canal in the mesiobuccal root. Materials and Methods. One hundred and fourteen permanent maxillary first molars were examined. The root numbers of the molars were recorded. Root canal morphology was studied using a clearing technique. T...

OBJECTIVE This study evaluated the wear in the apical third of simulate canals after preparation with ProTaper Universal Rotary System. MATERIAL AND METHODS 24 sets of instruments were used in 24 simulated canals in transparent epoxy resin blocks with degree of curvature of either 20 degrees or 40 degrees. The canals were photographed preoperatively and after preparation of the apical stop wi...
