PurposeTo investigate differences in surgical outcomes between open and closed exposure for palatally displaced maxillary canines.Materials and MethodsThis multicenter randomized controlled trial involved 2 parallel groups. The settings were 1 dental teaching hospital in and 2 hospital units near Sheffield, UK. Participants were younger than 20 years, had a unilateral palatally displaced maxillary canine, and provided informed consent. They were randomly allocated to receive the open or the closed surgical procedure. The outcomes were time spent in the operating room and 10-day postoperative patient questionnaire findings. Statistical differences between the 2 techniques were tested using independent t tests for continuous variables and χ2 tests for frequencies.ResultsThe final study sample was composed of 71 participants (64% female). There were no differences in the gender ratios (open: 27 female, 13 male; closed; 25 female, 16 male) or mean ages (open: 14.3 yrs; standard deviation [SD], 1.3 yrs; closed: 14.1 yrs; SD, 1.6 yrs) of the 2 groups at the start. The mean operating times for the open and closed techniques were 34.3 minutes (SD, 11.2 min) and 34.3 minutes (SD, 11.9 min), respectively (P = .986). There were no statistically significant differences between the 2 treatment groups for any patient-assessed outcome (P > .05).ConclusionsThere were no differences in the surgical outcomes investigated in this study between open and closed exposure for palatally displaced maxillary canines.
