Analysis of primary tooth dentin after indirect pulp capping.

Purpose: The purpose of this study was to evaluate the characteristics of primary molar dentin after indirect pulp capping (ICP) by of color, consistency and microhardness analyses.

Methods: The study design consisted of 3 groups: a test group of 13 primary molars that had been submitted to ICP with either calcium hydroxide or resin-modified glass ionomer cement; a positive control group of 15 sound molars; and a negative control group of 15 molars with deep acute carious lesions. The test group teeth had their restorations and pulp-capping materials removed and their cavity depth measured (mean depth=3-4 mm).

Injectability evaluation of tricalcium phosphate bone cement.

Calcium phosphate cements are biomaterials made from a mixture of calcium phosphate powder in aqueous solutions that forms a paste that reacts at the body temperature and hardens as a result of precipitation reactions. These cements are commonly used in dentistry and orthopedic bone filling surgeries, which require extremely invasive procedures. The challenge consists in formulating an injectable paste by additives incorporation.
