Summary

The aim of this study was to investigate the effect of mechanical vibration on root resorption with or without the application of orthodontic force.

Twenty patients who required maxillary premolar extractions as part of their orthodontic treatment were randomly separated into two groups of 10: no-force group and force group. Using a split-mouth procedure, each patient's maxillary first premolar teeth were randomly assigned as either vibration or control side in both groups. Buccally directed vibration of 113 Hz, using an Oral-B HummingBird device with a modified tip, was applied to the maxillary first premolar for 10 mins/day during 12 weeks. After the force application period, the maxillary first premolars were extracted and scanned with micro-computed tomography. Fiji(ImageJ) which made slice-by-slice quantitative volumetric measurements was used for resorption crater calculation. Total crater volumes was compared with Wilcoxon and Mann-Whitney U tests.

Mechanical Vibration

Oral B HummingBird device (Procter\&Gamble, USA) with a modified tip was used for the application of vibration. The tip was positioned mid-buccally of teeth to perform buccally directed vibration. HummingBird is prescribed maximum period 0.00885s corresponding to 6800RPM or 113Hz of the motor. The vibration procedure was applied for 10mins/day during the period of 12 weeks.
