This study investigates the effects of nano-hydroxyapatite (NHA) gel and Clinpro (CP) on remineralization potential enamel cementum at cavosurface area computer-aided design manufacturing ceramic restoration.Thirty extracted human mandibular third molars were sectioned 1 mm above below cemento-enamel junction to remove portions replaced them with zirconia disks by bonding crown root resin cement. The an 4×4 mm2 surrounding disk was demineralized carbopol. surfaces treated either NHA or CP, while group left no treatment. Vickers microhardness determined before demineralization, after remineralization. Analysis variance Tukey multiple comparisons used determine statistically significant differences 95% level confidence. Scanning electron microscopy X-ray diffraction evaluate for surface alterations.The mean ± SD 377.37±22.99, 161.95±10.54, 161.70±5.92 60.37±3.81, 17.65±0.91, 17.04±1.00 treatment group; 378.20±18.76, 160.72±8.38, 200.08±8.29 62.58±3.37, 18.38±1.33, 27.99±2.68 groups; 380.53±25.14, 161.94±5.66, 193.16±7.54 62.78±4.75, 19.07±1.30, 24.46±2.02 CP groups. indicated increase in upon application (p<0.05). Post hoc significantly higher capability both than (p<0.05), as evidenced scanning microscopy, indicating particle deposition remineralization, crystallinity accumulation, diffraction.NHA capable cementum. more process CP. extremely margin ceramic.
