ABSTRACT
Objectives: To investigate the influence of micro-osteoperforation (MOP) on rate of orthodontic tooth movement and pain perception with fixed appliances.
Design: 2 arm parallel randomized controlled trial with an allocation ratio of 1:1.
Setting: The outpatient department of a dental college.
Participants: 105 patients were screened, out of which 60 met the inclusion criteria and consented to participate; consisting of 33 females and 27 males requiring en-masse retraction following first premolar extractions.
Methods: The experimental group consisted of patients bonded with a fixed appliance (Gemini 3M) who received MOP distal to canines throughout the period of retraction every 28 days. These were compared with a control group treated with identical brackets without MOP and were assessed for rate of tooth movement (canine retraction) and pain perception using a Visual Analogue Scale (VAS) of 10 mm.
Results: Prior to commencement, all baseline parameters were matched between the two groups (p>0.05). A statistically significant increase in rate of tooth movement in the MOP group (p<0.05).
Conclusion: MOP appears to enhance the rate of tooth movement with no differences in pain perception.
