The main component of betel leaf (Piper betle Linn.) is tannin, which easily binds with proteins and can affect enamel hardness. Betel leaf extract was applied as a topical gel to the enamel of 18 bovine teeth specimens embedded in acrylic resin (three groups of 15%, 25%, and 35% gel applied for 1, 3, and 6 months). Enamel hardness was measured with a Knoop microindentation tester. Statistical analysis was done by repeated and one-way analysis of variance tests. A significant increase in microhardness was noted after 6 months of 15% betel leaf extract application (P < 0.05). Betel leaf extract gel can significantly affect enamel hardness.
