In vivo debonding strength and enamel damage in two orthodontic debonding methods

Bracket debonding strength related to diverse debonding methods and enamel demage has not been assessed in vivo. The study hypothetized a direct relationship between these three parameters.

Description
Summary:Bracket debonding strength related to diverse debonding methods and enamel demage has not been assessed in vivo. The study hypothetized a direct relationship between these three parameters. Debonding strength was measured clinically in the wings method and base method on 50 patients in a split mouth method using a calibrated debonding plier. Brackets from 30 of these patients were scanned in SEM and EDAX for adhesive remnant index and enamel calcium remnants. Base method debonding force was significantly greater than wings method (163.5±68.7N, 106.1±66.2N, respectively, p
