Effect of application of betel leaf extract gel on enamel surface roughness

Abstract

This study was conducted to determine the effect of application of betel leaf extract gel at different concentrations on enamel surface roughness. We treated 18 bovine enamels with betel leaf extract gel at 15%, 25%, and 25% concentrations every 4 min for 20 min, 40 min, and 44 min. We found a decrease in surface roughness with the application of 15% and 35% betel leaf extract gel for 20 and 40 min and an increase after 44 min. With the application of 25% betel leaf extract gel, we found an increase after 20 min but a decrease after 40 and 44 min. We conclude that betel leaf extract gel affects the surface roughness of tooth enamel. The most effective application was with 15% betel leaf extract gel for 3 months.
