ClinConnect Summary

Aims: to evaluate the pulpal blood flow (PBF) during orthodontic teeth alignment and leveling using clear aligners (second aligner) and fixed orthodontic appliance at different time intervals of orthodontic force application.

Materials and Methods: A total of 45 subjects were subdivided in two groups: group 1: 25 subjects treated with pre-adjusted edgewise fixed appliance with 0.014 inch NiTi as the alignment arch wire and group 2: 20 subjects treated using clear aligner. In both groups, PBF was measured for the upper right and the lower left using Laser Doppler Flowmetry at different time...
