White spot is the initial stage of caries resulting from tooth demineralization. Remineralization may repair the white spot by depositing minerals such as calcium onto the enamel surface. Chicken bone contains hydroxyapatite, which can be used as a remineralization agent. This study investigated the effect of applying chicken bone hydroxyapatite paste on calcium levels in teeth with white spot lesions. Eight caries-free premolar teeth were used in this study. The teeth were cut into 2 parts. White spot lesions were induced by applying 37% phosphoric acid for 60 seconds on the buccal surface, confined to a 5 mm diameter. The samples were divided into two groups: the treatment group and the positive control group. In the treatment group, hydroxyapatite was applied onto the white spots, while Casein Phosphopeptide-Amorphous Calcium Phosphate (CPP-ACP) was applied onto the white spots in the positive control group. The white spots were left untreated in the negative control of each group. The applications were done twice a day for 6 consecutive days. Samples were stored in artificial saliva and replaced every 24 hours. Calcium levels were measured using Atomic Absorption Spectrometer at ?=442.7 nm. Data were analyzed using Independent T-test. The Independent T-test results showed that the calcium levels in the hydroxyapatite-exposed group were significant compared to the negative control group (p<0>0.05). There was no significant difference in the calcium levels increment between teeth with white spots that were applied with HA when compared to CPP-ACP. Thus, the application of hydroxyapatite has an equivalent ability to CPP-ACP in increasing tooth calcium levels (p>0.05). In conclusion, the application of chicken bone hydroxyapatite paste enhances tooth calcium levels in white spot lesions.
