The aim of this study was to assess, in vivo, the accuracy of the NovApex® electronic foramen locator in determining working length (WL) in vital and necrotic posterior teeth. The NovApex®was used in 144 canals: 35 teeth with vital pulps (68 canals) and 42 teeth with necrotic pulps (76 canals). WL was measured with the NovApex® locator and confirmed using the radiographic method. Differences be...

INTRODUCTION This study compared the root canal microbial count of necrotic teeth after irrigation with 6% sodium hypochlorite (NaOCl) (single session treatment) and two-session root canal treatment with two-week application of calcium hydroxide (CH) mixed with 0.2% chlorhexidine (CHX) as intracanal medicament. METHODS AND MATERIALS In this randomized clinical trial, single-rooted necrotic te...

The objective of this study was to evaluate the bacterial profile in root canals of human primary teeth with necrotic pulp and periapical lesions using bacterial culture. A total of 20 primary teeth with necrotic pulp and radiographically visible radiolucent areas in the region of the bone furcation and/or the periapical region were selected. After crown access, 4 sterile absorbent paper points...

apexification is a method of inducing apical closure for non-vital immature permanent teeth. during this treatment a mineralized barrier is induced [with long term calcium hydroxide (ch) treatment]; or artificially created [with mineral trioxide aggregate (mta) plug]. this article describes two cases of apexification in immature necrotic teeth treated with these two different techniques. after ...

AIM The object of this study was the evaluation of the success rate of endodontic treatment of primary teeth with necrotic pulps performed through a partial pulpectomy and a chemical shaping. MATERIALS AND METHODS The study was conducted on 50 necrotic primary molars, with an oral fistula and a clinical and radiographical positive diagnosis. On each tooth the endodontic treatment was performe...

AIM To examine the clinical and radiographic appearance of teeth that suffered premature interruption of root development and were treated by an mineral trioxide aggregate (MTA) apical plug technique. SUMMARY Eleven teeth with immature root apices in 11 patients were treated nonsurgically by the manual application of MTA in the apical portion of the root canal under microscopic vision. Follow...
