Evaluation of bone tissue response to a sealer containing mineral trioxide aggregate.

Introduction: This study analyzed bone tissue reactions to MTA Fillapex (Ângelus Industria de Produtos Odontológicos Ltda, Londrina, Brazil) compared with an epoxy resin-based material in the femur of Wistar rats.

Methods: Bone tissue reactions were evaluated in 15 animals after 7, 30, and 90 days (n = 5 per period). Three surgical cavities were prepared on the femur and filled with 0.

Tissue reactions to a new mineral trioxide aggregate-containing endodontic sealer.

Introduction: The purpose of this study was to analyze the connective tissue reactions to MTA Fillapex (Ângelus Indústria de Produtos Odontlógicos Ltda, Londrina, Brazil) compared with a zinc oxide-based sealer (EndoFill; Dentsply Indústria e Comérico Ltda, Petrópolis, Brazil) and an epoxy resin-based material (AH Plus; Dentsply DeTrey GmbH, Konstanz, Germany) in Wistar rats.

Methods: Polyethylene tubes containing the test materials and empty polyethylene tubes (control) were implanted in the subcutaneous tissue of 12 rats. Empty tubes were used as a negative control.

Dentin bond strength of two mineral trioxide aggregate-based and one epoxy resin-based sealers.

Introduction: This study aimed at evaluating the bond strength to root dentin of 2 mineral trioxide aggregate (MTA)-based sealers (Endo-CPM sealer and MTA Fillapex) and of 1 epoxy resin-based sealer (AH Plus sealer).

Methods: Forty-five extracted human teeth with single roots were prepared by using the step-back technique. Irrigation with 2.
