THE EFFECT OF CASEIN PHOSPHOPEPTIDE- AMORPHOUS CALCIUM PHOSPHATE FLUORIDE, ORGANIC AND INORGANIC FLUORIDE IN PREVENTION OF DENTIN EROSION- AN IN VITRO STUDY.

Abstract

Context: Dental erosion is defined as the loss of tooth substance by acid exposure not involving bacteria. To enhance the remineralization and to prevent further progression of dental wear, highly-concentrated fluoride applications and calcium rich compounds are recommended Aims: The purpose of this study is to evaluate effect of casein phosphopeptide-amorphous calcium phosphate fluoride paste, organic and inorganic fluoride on the prevention of dental erosion. Settings and Design: In vitro Randomised Control trial Methods and Material: This in vitro experimental study 80 sound human premolar teeth (with no caries or fracture) were included. Buccal surfaces of the teeth were ground flat and polished with abrasive discs. Afterwards, half the tooth surfaces were covered with adhesive tape to maintain reference surface and samples were then randomly divided into four groups of 20 each. Samples were randomly allocated into four groups. Group A was pretreated with GC tooth mousse plus 4 times a day for 5 days. Group B was pretreated with 0.2% sodium fluoride mouthwash 4 times a day for 5 days. . Group C was pretreated with amine fluoride mouthwash 4 times a day for 5 days. Group D was considered as the control group with no pretreatment. In the next step, the samples were exposed to Coca-Cola 4 times a day for 3 days. After each erosive cycle, the samples were rinsed with deionized water and stored in artificial saliva. The surface loss was determined using profilometry.  Statistical analysis used: Unpaired ‘t’ test and ANOVA test . Results: The erosion in both Groups A, B and C was less than the control group. The surface loss in GC tooth mousse plus and mouthwash group was significantly lower than in the control group. Erosion in GC tooth mousse plus group was more than the mouthwash group and less than the control group.  Conclusions: Amine fluoride mouthwash is more effective for prevention of dentin erosion.
