On human dental enamel, the remineralisation efficiency of a subsurface enamel defect was evaluated using powder extracts from three marine skeletal species: Crassostrea madrasensis (oyster shell), Perna viridis (mussel shell), and Penaeus monodon (shrimp shell).Methods: The study included 60 freshly extracted human third molar teeth that were sectioned at the cement-enamel junction (CEJ). Later, each tooth coronal region was separated into two halves of enamel blocks, yielding 120 blocks that were exposed to the demineralization technique and categorised as follows: Subsurface demineralization + oyster shell powder extract form Group I. Group II: demineralization of the subsurface + mussel shell application Subsurface demineralization + shrimp shell powder extract (Group III). Group IV: subsurface demineralization plus clinpro application, followed by thirty days in artificial saliva. The intact enamel samples served as a positive control, whereas demineralized enamel samples served as a negative control. Using X-ray fluorescence spectroscopy, micro hardness testing, and energy dispersive x-ray spectroscopy,samples were evaluated for remineralisationThe samples were evaluated using X-ray fluorescence spectroscopy, energy dispersive x-ray spectroscopy and micro hardness testing for atomic analysis & surface microhardness. One-way ANOVA and the Tukey – Kramer multiple comparison tests were used for statistical analysis.
