Abstract
  • The purpose of this study was to compare treatment times for serial extractions (SE) and late premolar extractions (LPE) for a cost-effectiveness analysis. A retrospective chart review identified 51 SE and 49 LPE patients. PAR scores were obtained at the initiation (PAR T1) and completion (PAR T2) of active orthodontic treatment. PAR T1 scores for the SE patients were significantly less than that for the LPE patients (p<0.001) whereas PAR T2 scores were not significantly different. Active-treatment time was significantly less for the SE group as compared to the LPE group (p<0.001). Total time (mos. pre-active + active-treatment) and total number of visits was significantly greater for the SE group as compared to the LPE group (p<0.001). Total chair time (min.) was not significantly different between groups. Serial extractions may reduce active-treatment time for severe crowding but a significant time and effort precedes active-treatment.
