An increasing number of testimonials and instructional materials are spreading online linking potassium, magnesium, and manganese as responsible agents for tooth whitening. This study determined the whitening capacity of the inside surface of the banana peel. METHODOLOGY: An in vitro animal study was done using fifty (50) bovine teeth, scaled and polished, allocated into 3 treatment groups with different contact time duration based on the instruction online (2 minutes, 30 minutes, 1 hour) and 2 control groups (Positive control: Crest Whitening application group as per manufacturer’s instruction; Negative Control: tooth brushing), for 14 days. Baseline shade and final shade were determined for each tooth by a third-party shade selector using a Vita Shade Guide system following Munsell Value Chart RESULTS: Kruskal-Wallis test revealed no significant change in shade apparent in all treatment groups (p = 0.0057). When compared to the positive control, the Crest Whitening group revealed a generalized positive (lighter) shade change. Regardless of the duration of contact time per day between enamel and peel residue, all 3 treatment groups and the tooth brushing group alone generally showed no change in tooth shade after 14 days. CONCLUSION: Banana peel did not lighten the shade of extracted bovine teeth. Time or contact duration between enamel and banana peel residue did not show tooth shade changes. Teeth-Bleaching.
