ABSTRACT
Objectives: To compare the remineralization effect of Camellia sinensis and Theobroma cacao on enamel surface roughness. Methods: Eighteen premolars were etched with 37% phosphoric acid and divided into six groups. Group A (positive control) received fluoride varnish for 2 minutes, and Group B (negative control) was immersed in artificial saliva. Groups C and D were immersed in Camellia sinensis extract for 2 and 5 minutes, respectively, while Groups E and F received Theobroma cacao extract for 2 and 5 minutes. After treatment, samples were immersed in artificial saliva for 24 hours at 37°C. Surface roughness was measured. Results: A paired t-test showed a significant reduction in surface roughness in all groups except Group B (p<0.05). One-way ANOVA revealed significant differences between treatment groups (p<0.05). The 5-minute Theobroma cacao group showed the greatest reduction in roughness. Conclusions: Both extracts reduce enamel surface roughness, with Theobroma cacao showing the highest effectiveness as a remineralization agent.
