Orthodontic treatment causes Pathologic resorption
Dudic etalJ Clin Periodontol 2008 p 1


Objectives: To assess the relationship between periodontal parameters and cervical
root resorption in orthodontically moved teeth.

Material and Methods: In a standardized experimental tooth movement in 16
periodontally healthy subjects, 29 pre-molars were tipped buccally for 8 weeks.
Eighteen contralateral pre-molars not subjected to orthodontic movement served as
controls. Plaque Index (PI), Gingival Index (GI), probing depth and bleeding on
probing were assessed three times before and six times during the experimental phase.
Teeth were extracted and scanned in a micro-computed tomography scanner. The
presence or absence, and the severity of cervical root resorption were evaluated on the
three-dimensional reconstruction of the scans by two calibrated examiners.

Results: Overall, periodontal parameters were not different between the test and the
control teeth. Clear signs of buccal cervical resorption were detected on 27 of 29
orthodontically moved teeth and on one control tooth. Ten subjects had perfect oral
hygiene and no gingivitis, whereas six subjects showed a moderate level of plaque and
gingivitis (420% occurrences of PI or GI with 40). No relationship could be
demonstrated between resorption and periodontal parameters.

Conclusions: Nearly all orthodontically moved teeth showed signs of cervical
resorption. Periodontal parameters were unrelated to this important side effect of
