Objective: To find out effect of metal brackets on the epithelial cells of the buccal mucosa as compared to normal mucosa without any brackets. Patients and Methods: Oral mucosal smears were obtained for patients visited for orthodontic treatment using a cytobrush. The study group consisted of P1: patients with no brackets, P2: 60 days after placement of metal brackets, P3: 30 days after removal of brackets. 30 individuals of both sexes who are undergoing fixed appliance theropy with bonded brackets were selected. With the use of exfoliative cytology, morphometric and morphologic changes in buccal mucosa cells adjacent to these brackets were determined and were compared at three points. Results: A decrease in nuclear area and an increase in cytoplasmic area occurred in the buccal mucosa cells adjacent to the brackets at P2 . At P3, this altered morphometry persisted only in cells adjacent to the metal brackets, although to a lesser degree than at P2 . A greater decrease in nuclear area was noted in cells adjacent to the metal brackets than in those for patients P1 . At all time points, smears of cells appeared normal or normal with some inflammatory changes. Conclusion: Placement of metal brackets in the buccal cavity induces cellular alterations. These alterations do not suggest malignancy.
