DEMINERALIZATION OF TOOTH ENAMEL SURFACE AT DIFFERENT IMMERSION TIMES OF SPORT DRINK AND BUFFERING EFFECT OF CASEIN DERIVATIVE AGAINST ENAMEL EROSION

Introduction: Sports drinks are becoming increasingly popular as well as being encouraged with regular exercise. These drinks are less than normal pH and found to be acidic.These acidic bevarages are thought to increase potential for dental erosion.Casein Phosphopeptide - Amorphous Calcium Phosphate CPP-ACP complex helps to release Calcium, Phosphate ions to form apatite crystals. In acidic conditions, these calcium, phosphate ions are released from crystal complex and facilitate to reduce the extent of demineralization. This concept forms the basis for the study. Objective: To estimate the pH values of Sport drink(Redbull) before and after immersion time. To estimate the loss of mineral content of the tooth exposed to sports drink with and without CPP-ACP. Material & Methods: Extracted premolar teeth of human dentition free of dental caries and hypocalcification were selected. Teeth were sectioned to obtain 3 enamel sections from each tooth to obtain 15 sections. Specimens were immersed in Sports drink(Redbull) Procedure (A) ,Sportsdrink (Redbull) +CPP-ACP Procedure (B) and Control Procedure (C) for 48 hours,24 hours,12 hours,6 hours,3 hours. pH Values before and after proce
