Laser lingual frenectomy in orthodontics: An observational study on efficacy and relapse

Introduction: Ankyloglossia is a fairly common abnormality that affects both adults and children. Several orthodontic problems have been associated with or attributed to this condition. A surgical release is advisable when functional hindrances arise. Diode laser frenectomy is a viable option for treating ankyloglossia. Currently, there is a lack of data on the degrees of recurrence and relapse after this intervention. Methods: An observational study on 32 consecutive cases was conducted at the University of Padua to assess the degree of ankyloglossia recurrence after diode laser lingual frenectomy. Measurements were taken one week, one-month and six-months after the intervention. Results: Using Ruffoli's measurement, a statistically significant effect of time (p = 0.0105) was apparent six months after the intervention, with an increasing tongue frenum over time from a mean of-2.54 (-3.89;-1.18) to-3.86 (-5.21;-2.50). No statistically significant effect of time emerged using Kotlow’s or Total measurements, however. Conclusions: The degree of recurrence after diode laser lingual frenectomy proved to be very low (p = 0.0105).
