Physical properties of root cementum: Part 26. Effects of micro-osteoperforations on orthodontic root resorption: A microcomputed tomography study.

Abstract Studies have demonstrated the potential efficacy of micro-osteoperforations in accelerating tooth movement by amplifying the expression of inflammatory markers. The aim of this investigation was to examine the effects of micro-osteoperforations on orthodontic root resorption with microcomputed tomography.

AB  - INTRODUCTION: Studies have demonstrated the potential efficacy of
      micro-osteoperforations in accelerating tooth movement by amplifying the
      expression of inflammatory markers. The aim of this investigation was to examine 
      the effects of micro-osteoperforations on orthodontic root resorption with
      microcomputed tomography. METHODS: This prospective controlled clinical trial
      involved 20 subjects requiring extraction of the maxillary first premolars as
      part of their orthodontic treatment. A buccal tipping force of 150 g was applied 
      to both premolars. Using the Propel appliance (Propel Orthodontics, San Jose,
      Calif), micro-osteoperforations were applied at a depth of 5 mm on the mesial and
      distal aspects in the midroot region of the experimental side of the first
      premolar root; the contralateral side served as the control. After 28 days, both 
      premolars were extracted. The teeth were scanned under microcomputed tomography, 
      and the volumes of root resorption craters were calculated and compared. RESULTS:
      Premolars treated with micro-osteoperforation exhibited significantly greater
      average total amounts of root resorption than did the control teeth (0.576 vs
      0.406 mm(3)). The total average volumetric root loss of premolars treated with
      micro-osteoperforation was 42% greater than that of the control teeth.
      CONCLUSIONS: This 28-day trial showed that micro-osteoperforations resulted in
      greater orthodontic root resorption. However, these results should be verified in
      patients who are undergoing full-length orthodontic treatment.
