BACKGROUND Root fractures are a relatively rare type of injury with frequencies of 0.5-7% of traumatized permanent teeth. It is well known that teeth with intra-alveolar root fractures have a good prognosis. The pulp remains vital in about 80% of these teeth. If pulp necrosis develops, this normally only occurs in the coronal fragment. Although several studies on intra-alveolar root fractures h...

Coronal discoloration of endodontically treated teeth is a challenge in clinical dentistry. This study aimed to compare coronal induced by White Mineral Trioxide Aggregate and Calcium-enriched mixture cement. Fifty single-rooted, unrestored premolar extracted for orthodontic reasons were selected. After access cavity preparation, all the root canals instrumented with MTWO rotary files up #40.6%...

INTRODUCTION The American Association of Endodontists clinical considerations for regenerative therapy (April 2015) advise of the risk of the possible adverse effect of staining of teeth. It is widely acknowledged that before these guidelines were developed there was no standardized protocol for regenerative therapy, and different approaches using different materials have been reported. The pur...

OBJECTIVES The aim of this study was to evaluate tooth discoloration induced by contact with various calcium silicate-based pulp capping materials in the presence or absence of blood in vitro. MATERIALS AND METHODS Eighty bovine samples were divided into six experimental groups and two control groups according to the type of material used (ProRoot [PR], Endocem [EC], or EndocemZr [ECZ]) and t...

AIM To investigate the discoloration potential of endodontic materials using a bovine tooth model. METHODOLOGY Two hundred and 10 dentine-enamel cuboid blocks (10 × 10 × 3.5 mm) were prepared out of the middle thirds of bovine tooth crowns. Standardized cavities were prepared in the walls of the pulp chamber leaving 2 mm of enamel and dentine on the labial wall of the crown. The specimens wer...
