A new concept in hybridization: Bromelain enzyme for deproteinizing dentin before application of adhesive system
نویسندگان
چکیده
OBJECTIVE The objective of this study is to assess the deproteinizing effect of bromelain enzyme and compare it with neodymium-doped yttrium aluminum garnet (Nd:YAG) laser and 10% sodium hypochlorite (NaOCl) by using scanning electron microscope (SEM) and polarized microscope. MATERIALS AND METHODS A total of 60 extracted human upper premolars were selected to be given standardized buccal and lingual class V cavities. The teeth were divided into three groups each one consisted of 20 teeth. Thirty teeth were recruited for SEM study and the other 30 for polarized microscope. Group 1: Teeth were deproteinized with Nd:YAG laser, Group 2: Teeth were deproteinized with bromelain enzyme and Group 3: Teeth were deproteinized with 10% NaOCl. RESULTS AND CONCLUSIONS Application of bromelain enzyme has led to removing collagen network and significantly decreased the global leakage scores of the adhesive system.

Background and Aim: Achieving adhesion between restorative materials and dentin as a wet and dynamic surface is an important topic in restorative and especially in conservative dentistry. Adhesion of new dentin bonding systems depends on the formation of hybrid layer and micromechanical retention. Nevertheless, an ideal adhesive system has not yet been introduced .Recent studies reveal an incre...

Statement of Problem: Considering that the role of collagen fibers in dentin adhesion has not been thoroughly established yet, the removal of exposed collagen fibers with a deproteinization agent such as sodium hypochlorite following etching may facilitate access of adhesive resins to a substrate that is more penetrable and less sensitive to water content which in turn would lead to a more dura...
