The effect of first and second premolar extractions on third molars: A retrospective longitudinal study

Conclusions The retromolar space and the position of third molars significantly change during orthodontic treatment in growing patients. Premolar extractions have a positive influence on the eruption space and vertical position of third molars, whereas they do not influence the angular changes of third molars. Due to the retrospective character of the study, these conclusions should be carefully reflected. Further prospective research is necessary for better insights into this complex topic. Clinical significance This study stresses the importance of considering the possible effects of orthodontic treatment on third molars during treatment planning.
