Abstract
Objective This study aimed to investigate the effect of hydroxyapatite from snakehead (Channa striata ) fish bone on the surface hardness of the enamel of the primary teeth.
Materials and Methods Twenty-six primary maxillary incisors were mounted on self-cured acrylic resin, divided
into two groups, and demineralized. Remineralization was performed using hydroxyapatite
paste synthesized from C. striata fish bone by the precipitation method. The case group was subjected to 15% hydroxyapatite
paste and subsequently submerged in artificial saliva, while the control group was
only exposed to artificial saliva. Enamel hardness was measured by the Vickers hardness
tester after 7 days of treatment. The statistical analysis used in this research was
an independent t-test.
Results The case group had a surface hardness of 356.192 ± 25.218, and the control group
had a surface hardness of 269.686 ± 22.931. Statistical tests showed a significant
difference between the case and control groups.
Conclusion Hydroxyapatite paste from snakehead (C. striata ) fishbone stimulates remineralization of primary teeth, as evidenced by an increase
in the enamel surface hardness of the teeth.
