INTRODUCTION Providing adequate coronal seal of temporary filling materials is critical for the success of root canal therapy. The aim of this in vitro study was to compare coronal seal ability of three restorative materials over different periods of time. MATERIALS AND METHODS Ninety-eight molar teeth were selected. Once access cavities were prepared, teeth were divided randomly into three t...

introduction: the aim of the present study was to investigate and compare the apical sealing ability of resilon/epiphany-filled root canals with those that were obturated with gutta-percha/ah-plus endodontic sealer. materials and methods: a total of 60 extracted human single-rooted teeth were selected; 25 teeth for each test group and five for each control group. after conducting conventional e...

introduction: the aim of this study was to evaluate the apical and coronal sealing of endodontic fillings promoted by the associations of sealer 26/gutta-percha, endofill/gutta-percha and resilon/ epiphany. materials and methods: it was used 38 human canines, 10 teeth for each test group and 4 teeth for each control group. after teeth conventional endodontic treatment, they were immersed in sal...

Endodontic management of the teeth with immature apices and necrotic pulps has always been challenging. Therefore fabrication of an artificial hard tissue barrier with a biomaterial has indicated as an alternative to more traditional apexification procedure. Successful endodontic treatment needs to prevent leakage of intracanal irritants into the peri radicular tissues. On the other hand, achie...
