Natural fruit peels as teeth whitening agents on primary teeth an in vitro study

Context: Dental Bleaching or tooth whitening represents a conservative cosmetic approach even for children and adolescents, for whom treatment may be readily accomplished without permanent alteration to the enamel surface thus limiting the need for lifelong maintenance. Aims: The aim of this study was to compare the efficacy of banana peel and orange peel as teeth   whitening agents in deciduous dentition. Methods and Material: Twenty extracted primary anterior teeth were used in this study and each crown was sectioned mesiodistally to obtain 40 samples which were flattened to create a standardized enamel surface. After the staining procedure, 40 samples were allocated into 4 groups, i.e., 10 samples per group, the standard group (35% Hydrogen peroxide), the control group (distilled water), banana peel and orange peel. The samples of each group were treated using the respective agents with standardized pressure and time. Results: The tooth shades were assessed using Digital Spectrophotometer at baseline, 1 week of staining, 1 week of bleaching and 1 week post bleaching. All the results were statistically analysed with Post Hoc Tukey’s test. Both the study groups showed significant changes but, banana peel showed better efficacy than orange peel. Conclusions: Banana peel and orange peel can be considered for teeth whitening in deciduous dentition.
