Abstract: This study compares the enamel mineral content after bleaching using In-Office, At-Home and Combined Techniques, utilizing a Scanning Electron Microscope (SEM) equipped with Energy Dispersive X-Ray Analysis (EDX). Fifty-six human premolar teeth were divided into four groups, each subjected to different bleaching techniques. Results indicated that In-Office bleaching led to the most significant loss of calcium and phosphorus, while At-Home and Combined techniques showed less mineral reduction. Statistical analysis confirmed significant differences in mineral content across the groups.
