Orthodontic force application for aligning teeth,causes initiation of acute inflammatory processes leading to periodontal ligament tissue injury. It is advised that light continuous forces should be used during orthodontic treatment to minimize tissue damage and subsequent pain and discomfort.(1) The present study was aimed to evaluate the effect of using low-level laser therapy (LLLT) to control pain and discomfort during the initial hours of levelling and aligning phase of orthodontic treatment. The methodology was to compare and evaluate the pain perception using an Visual Analogue Scale (VAS) between patients who were given 0.016 Conventional NiTi(Group 1) and0.016 Conventional NiTi with exposure to LLLT, AIGaAs diode, (810 nm, 100 mW, 2J/cm2) (Group 2) at regular intervals of 24 hours, 48 hours and 72 hours each consisting of a sample size of 7. A total of 14 subjects participated in the study, each group consisting of 7 subjects. The mean pain perception score was 1.71±0.48 and 1.71±0.48 at 0 hours, 2.42±0.97 and 2.42±0.53 at 24 hours, 3.42±0.53 and 2.71±0.48 at 48 hours, 3.85±0.69 and 3.00±0.57 at 72 hours, for Group 1 and Group 2 respectively. There was no significant difference between the two groups, but at 72 hours the difference improved (p=0.004) in group 2 indicating there was a decrease in pain perception with time. It was concluded that there was no statistically significant difference between the two groups. However, subjects with nickel–titanium arch wires when exposed to LLLT had a significantly lower pain at peak level.
