Objective: This study aimed to determine the exposure time needed for hydroxyapatite to show a hardness reduction comparable to enamel in an artificial caries-inducing solution.
Methods: Bovine enamel samples were corroded for 4 hours (1-hour intervals), while hydroxyapatite blocks underwent 20 hours of corrosion (four 1-hour intervals followed by four 4-hour intervals). Microhardness was measured before and after each exposure.
Results: Bovine enamel hardness decreased by 68.0% after 1 hour, while hydroxyapatite hardness decreased by 72.6% after 16 hours of exposure.
Conclusion: Hydroxyapatite required 16 hours to show a similar hardness reduction to bovine enamel’s 1-hour exposure, suggesting that corrosion of hydroxyapatite should last 16-20 hours for comparable effects.
