Overview

This retrospective study compares external root resorption in treated and vital teeth, suggesting no increased risk for endodontically treated teeth.

Key Points

  • To compare external apical root resorption in vital and endodontically treated teeth following orthodontic treatment.
  • Retrospective longitudinal study of 60 patients undergoing non-extraction fixed orthodontic treatment.
  • Used a paired contralateral within-subject design for comparison.
  • Measured root length on panoramic radiographs before and after treatment.
  • Analyzed differences using Wilcoxon signed-rank and Kruskal-Wallis tests.
  • Both tooth types showed significant reductions in root length after treatment.
  • Mean reduction in root length was approximately 1 mm for both tooth types.
  • No significant differences in root resorption between endodontically treated and vital teeth.
  • No significant differences noted among different Angle Classes of malocclusion.
