Abstract :

Introduction: This study evaluated and compared the duration for retraction of maxillary canines in subjects who underwent piezocision and low-level laser therapy. Materials and Methods : The study sample consisted of 12 adult patients in a prospective randomized split-mouth study design, requiring therapeutic extraction of bilateral maxillary first premolar and bilateral canine distalization. The subjects were evaluated for 4 months or till the time taken for the maxillary canine to achieve positive contact with the maxillary second premolars bilaterally. Intervention in the form of low-level laser therapy was carried out on one side using a diode laser vis-a viz piezocision on the other side. This was followed by a comparative evaluation of canine retraction due to both the interventions on their respective sides. Results: The LLLT group showed 1.105 times the canine retraction in 4 months as compared to the group subjected to piezocision and the findings are statistically significant (P Value = 0.09) using paired t test . The canine showed a mean distal movement of 3.14mm and 2.84 mm in LLLT and piezocision group respectively. Conclusion: The rate of tooth movement is slightly higher in teeth exposed to LLLT. From the results, we can also infer that there is a constant decline in the rate of tooth movement throughout the duration of the study. With no need for incision and a lesser chance of damage to hard and soft tissue, LLLT appears to be a comparatively attractive option for acceleratory orthodontics.
