Effects of 40"1'. Phosphoric Acid Etch on the Compressive Strength of Biodentine

Abstract

Objective: This in-vitro study investigated whether an application of 40%phosphoric 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 9917:2010 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 30mm/min. Twenty specimens from each group were tested.
