Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.

Study Groups

Conventional fixed appliance
A pre-adjusted edgewise fixed appliance (3M Gemini Unitek, 0.022" Roth prescription brackets) on one side of lower arch.
A Pre-adjusted edgewise brackets: 3M Gemini Unitek, 0.022" Roth prescription brackets
A pre-adjusted edgewise fixed appliance (3M Gemini Unitek, 0.022" Roth prescription brackets) on one side of lower arch. The standardized bonding technique was applied according to the manufacturer's instructions. Teeth alignment was initiated using round 0.016" NiTi arch wire until 0.016X0.022" NiTi was reached. The NiTi arch wires were placed into brackets slots and tied with elastomers (figure of 8).
Self ligating fixed appliance
Self-ligating brackets (Unitek™ Gemini SL Self-Ligating Brackets, 0.022" Roth prescription brackets) on the other side.
Self- ligating brackets: Unitek™ Gemini SL Self-Ligating Brackets, 0.022" Roth prescription brackets
Self-ligating brackets (Unitek™ Gemini SL Self-Ligating Brackets, 0.022" Roth prescription brackets) on the other side of lower arch. The standardized bonding technique was applied according to the manufacturer's instructions. Teeth alignment was initiated using round 0.016" NiTi arch wire until 0.016X0.022" NiTi was reached. The NiTi arch wires were placed into brackets slots and held in place by bracket's gate in the self-ligating brackets side.
