Abstract

Aim: To evaluate the effectiveness of calcium lactate added to various soft drinks on dental erosion. Objective of the study: Assessment of dental erosion to soft drinks with and without the presence of calcium lactate. Materials and methods: 3 soft drinks (Maaza, Appy Fiz and Pepsi) and normal water were taken. 40 dental blocks were randomly allocated into 4 groups. Surface loss was assessed using Digital Surfometry. Surfometry readings were taken before and after adding calcium lactate in the above soft drinks for definite time intervals. Results: In the present study Pepsi had the highest acidic pH (2.7) and showed the highest degree of erosion with a mean value of 1.55µ. After adding calcium lactate, highest acidic pH was shown by Appy fiz (4.45) but degree of erosion was still the highest for Pepsi with a mean value of 1.36µ. Later each group was compared for surface loss among themselves with and without the presence of calcium lactate. Appy fizz showed the highest degree of erosion with a mean value of 0.22µ. Conclusion: Erosive action of soft drinks varies widely. The results demonstrate that the addition of 5% calcium lactate to soft drinks significantly decreased dental erosion.
