Orthodontic treatment simultaneous to or after periodontal cause related treatment in periodontally susceptible patients

Abstract

Aim

To compare two treatment strategies regarding the effect of orthodontic treatment on periodontal status in patients with plaque-induced periodontitis.

Subjects and Methods

This was a randomised clinical trial. Fifty periodontal patients were randomly assigned to the test or control groups according to periodontal treatment timing. All patients received supra- and sub-gingival debridement following baseline examination. Control group patients received cause-related periodontal treatment before the start of orthodontic treatment and which was performed simultaneous to orthodontic treatment for the test group patients.

Results

No difference between the test and control groups was found regarding change of clinical attachment level (CAL) after periodontal-orthodontic treatment. Fewer sites with initial pocket depth (PD) of 4-6 mm healed after periodontal-orthodontic treatment in the test group (20.5%, IQR=11.9%) in comparison with controls (30.4%, IQR=27.1%) (p=0.03). Anterior teeth [OR 2.5] and teeth in male patients [OR 1.6] had a greater chance for PD improvement ≥2mm. Total periodontal-orthodontic treatment duration was significantly longer for the control group (p<0.01).

Conclusions

Both groups showed a gain of CAL and a reduction of sites with PD ≥ 4mm.

Orthodontic treatment, simultaneously to the periodontal treatment, could be used in the routine

treatment of patients with plaque-induced periodontitis.
