The effect of four materials on direct pulp capping: An animal study.

The aim of this study was to investigate the outcomes of direct pulp capping performed with two types of tricalcium silicate-based materials (mineral trioxide aggregate/MTA and Biodentine/BD); nano-hydroxyapatite (nHAP) crystals or calcium hydroxide (CH) in dogs. Following mechanical exposure, the pulps were randomly capped with one of the four materials. Histological analyses were performed to examine the outcomes after 7 days or 3 months.

Antimicrobial activity and pH measurement of calcium silicate cements versus new bioactive resin composite restorative material.

Background: The purpose of this in vitro study is to compare the antimicrobial effect and pH of two calcium silicate cements Mineral trioxide aggregate high plasticity (Angelus PR, Brazil) and iRoot BP Plus (BioCeramix Inc., Vancouver, BC, Canada) and new bioactive restorative resin composite restorative material (ACTIVA, MA, Pulpdent, USA) against aerobic bacteria, strictly anaerobic bacteria and a yeast by using an agar diffusion test.

Methods: The materials were tested immediately after manipulation and were applied to the agar plates.

Biodentine versus mineral trioxide aggregate as a direct pulp capping material for human mature permanent teeth - A systematic review.

Background: Biodentine is comparatively a new biomaterial claimed to have properties comparable to mineral trioxide aggregate (MTA). Biodentine and MTA are effectively used for direct pulp capping (DPC), and they are capable of regenerating relatively damaged pulp and formation of hard dentine bridge.

Objectives: The aim of this systematic review was to test the null hypothesis of no difference between Biodentine and MTA as DPC materials for human permanent mature teeth, against the alternative hypothesis of a difference.
