Abstract

Objective: To evaluate the healing effectiveness of the diode laser in frenuloplasty. Subjects and Methods: This is a clinical trial study with a before-and-after design without a control group, conducted on children aged 3 to 6 years, diagnosed with grade 3 and 4 tongue tie according to Kotlow's classification of tongue tie in 1999. All patients underwent tongue frenuloplasty surgery using a 940±10 nm diode laser, with a peak power of 2W, average power of 1W, and a pulse duration of 1ms; the surgical tip used was activated with a diameter of 400µm. The evaluated parameters included the level of postoperative pain at 1 day, 3 days, and 1 week; assessment of bleeding during the surgery; wound healing evaluation at 3 time points (1 day, 3 days, and 7 days); and the measurement of the free tongue length before surgery, 1 week, and 1 month post-surgery. Results and Conclusion: Within the scope of this study, frenuloplasty using a diode laser demonstrated rapid healing, minimal bleeding, low pain levels, and complete release of the tongue tie, thereby improving the tongue movement in children.
