Abstract:

Objective This in-vitro study investigated whether an application of 40phosphoric acid etch significantly alters the compressive strength of Biodentine, a relatively new calcium silicate based dentin replacement material. Materials and Methods Compressive strength of Biodentine was determined according to ISO 99172010 and ADA specification No. 96 for water based cements. Specimens were prepared using stainless steel cylindrical split molds with the internal dimension of 4.0 - 0.1mm in diameter and 6 - 0.1mm in length. Specimens were stored in 100 humidity at 37 degrees Celcius for 15minutes before they were randomly divided into two groupBiodentine subjected to 40 phosporic acid etch and non-etched Biodentine. The specimens were then loaded to failure in compression using a cross head speed of 30mmmin. Twenty specimens from each group were tested.
