OBJECTIVES: To characterize the re-mineralization potential of an experimental zirconium oxide (ZrO2) containing tricalcium silicate (TCS) cement, TCS 50, with the incorporation of biomimetic analogs at demineralized dentin. METHODS: Class-I cavities were prepared in non- carious human third molars. The dentin cavities were demineralized using a pH-cycling protocol, involving 50 cyclic immersions in pH-4.8 and pH-7 baths for 0.5h and 2.5h, successively. The cavities were filled with TCS 50 with/without biomimetic analogs (3% polyacrylic acid, 8% sodium trimetaphosphate) being added to the mixed TCS 50 cement prior to application...

Maxillary molars have highly variable root canal morphology. However, the presence of the two roots is a rare occurrence. The success of pulpectomy treatment depends on removal of infected pulp and filling it with a biocompatible material. In order to achieve it, the clinicians should understand the morphology of the individual root canal and atypical root canal configuration. The purpose of this article was to describe an unusual anatomy in primary maxillary second molar with missing successor tooth. Biodentine™ a new dentine substitute was used as an obturating material for retained maxillary second molar...

The aim of this study was to evaluate the sealing ability and marginal adaptation of calcium silicate-based cements (CSCs) in root-end cavities prepared by ultrasonic and laser tips. A total of 72 extracted human maxillary incisor teeth were randomly divided as 60 teeth in experimental groups and 6 teeth each for positive and negative control groups. Specimens in experimental groups were obturated, their root-end resections were performed and randomly divided into six groups (n = 10) as follows: G1: Ultrasonic retrotip + MTA, G2: Ultrasonic retrotip + Calcium Enriched Mixture (CEM), G3: Ultrasonic retrotip + Biodentine, G4: Er:YAG laser tip + MTA, G5: Er:YAG laser tip + CEM, G6: Er:YAG laser tip + Biodentine...

INTRODUCTION: Flow and filling ability are important properties of endodontic materials. The aim of this study was to propose a new technique for evaluating flow using micro-computed tomographic (μCT) imaging. METHODS: A glass plate was manufactured with a central cavity and 4 grooves extending out horizontally and vertically. The flow of MTA-Angelus (Angelus, Londrina, PR, Brazil), zinc oxide eugenol (ZOE), and Biodentine (BIO) (Septodont, Saint Maur des Fossés, France) was evaluated using International Standards Organization (ISO) 6876/2002 and a new technique as follows: 0...
