Clinical Trial Summary

This study was conducted to compare the rate of second molar protraction, level of Interleukin1-β in gingival crevicular fluid, periodontal health (gingival index, plaque index, and periodontal pocket depth) and root resorption in patients treated by molar protraction with piezocision performed early at the time of protraction (Group 1), piezocision performed 3 months after molar protraction (Group 2), and no piezocision molar protraction (Group 3).


Clinical Trial Description

Detailed Description: Thirty-five subjects who presented with bilaterally extracted mandibular first molar were selected to participate in the study. The subjects were subdivided into one of 3 groups as follows: group 1 consisted of 20 subjects /20 molars where piezocision was performed immediately before molar protraction; group 2 consisted of 20 subjects/ 20 molars where molar protraction was carried on after 3 months of molar protraction with no piezocision; group 3 consisted of 20 subjects (40 molars) where protraction was carried out with no piezocision.

After reaching 0.019X0.025" SS arch wire, NiTi coil spring was used for space closure (protraction force was 150g) attached from the lower second molar hook to the head of the mini-screw. Piezocision was performed by making 2 vertical incisions mesial and distal to the extraction space. Piezotome was inserted in the incisions previously made and bone cuts were done with a length up to mucogingival line and depth of 3 mm. Gingival crevicular fluid (GCF) sample was obtained from the mesiogingival side of the lower second permanent molar with use of Periopaper. GCF sample was repeated 1 day, 1 week and 4 weeks after molar protraction with piezocision or with no piezocision. Periodontal parameters were measured and lower molar root resorption was assessed using Perapical radiographs. ;
