简要总结
- Evaluate and compare initial changes in PBF between conventional and self-ligating fixed orthodontic brackets during leveling and alignment stage using 0.016" Nickle titanium (NiTi) and 0.016X0.022" NiTi archwires at different time intervals (20min, 24h, 72h, 1 week and 1 month) of initial arch wire placement.
详细描述
Objectives: to evaluate and compare the initial changes in pulpal blood flow (PBF) between conventional and self-ligating fixed orthodontic brackets during leveling and alignment stage.
Materials and Methods
A total of 22 patients (16 females and 6 males) aged 19± 2.53 years who presented with mild lower arch crowding were selected to participate in the study. A split mouth study design was applied for each patient. Two different fixed appliance brackets were used in the lower arch (self-ligating brackets on one side and conventional brackets on the other side of the same patients). PBF was measured for the lower right and left sides using Laser Doppler Flowmetry at different time intervals (20min, 24h, 72h, 1 week and 1 month) after the fitting of 2 alignment archwires; 0.016" NiTi and 0.016X0.022" NiTi. A repeated measures analysis of variance test and a Bonferroni post-hoc comparison test were applied to detect differences in PBF between the 2 groups.
