AIM AND OBJECTIVE: The aim of this study is to evaluate the rate of tooth movement caused by laser during individual canine retraction in the maxillary arch. MATERIALS AND METHODS: The study was done on 10 patients requiring upper first premolar extraction on both the sides and individual canine retraction using closed NiTi coil spring with high anchorage. A split-mouth technique was carried out where the right quadrant was the experimental side and left quadrant was the control side. On experimental side, canine was irradiated with Ga-As semiconductor laser (wavelength – 940 nm, output – 0.2 mW for 25 s, energy density – 5 J/cm2). Amount of retraction was measured using digital caliper on the cast. A palatal plug was used as a reference to ascertain retraction of canine. RESULTS: Results showed statistically significant difference in tooth movement on the experimental sides compared to control side. CONCLUSION: Hence, it can be concluded that laser effectively accelerates the tooth movement and reduce the treatment duration in clinical practice.
