Effect of different boron contents within boron-doped hydroxyapatite-chitosan nano-composite on the microhardness of demineralized enamel.

Objective: Dental caries is a prevalent chronic disease globally, arising from an imbalance between tooth remineralization and demineralization. Early detection of lesions is crucial, with non-invasive methods preferred in the initial stages of caries for enamel remineralization and demineralization prevention. This study aimed to assess the impact of varying contents of boron-doped hydroxyapatite-chitosan nano-composite on the microhardness of demineralized enamel.
