Healing Efficacy of Diode Laser in Lingual Frenectomy

22 de abril de 2026 actualizado por: Phong Dai Lam, University of Medicine and Pharmacy at Ho Chi Minh City

Evaluation of the Healing Efficacy of Diode Laser in Lingual Frenectomy

This study aims to compare the wound healing efficacy and postoperative experiences between the 940 nm diode laser technique and the traditional electrosurgery method for treating ankyloglossia (tongue-tie) in children aged 3 to 6 years.

Participants are randomly assigned to one of two groups: Experimental Group - Patients undergo lingual frenectomy using a 940 nm diode laser and Active Comparator Group - Patients undergo the procedure using conventional high-frequency electrosurgery.

The study evaluates several key outcomes at multiple intervals (24 hours, 3 days, 1 week, and 1 month post-surgery), including: (1) Wound Healing: Measured by the Early Wound Healing Score (EHS); (2) Pain Levels: Assessed using the Wong-Baker FACES Pain Rating Scale; (3) Bleeding Control: Evaluation of intraoperative bleeding; (4) Tongue Mobility: Measurement of free tongue length according to Kotlow's classification.

The goal is to determine if the diode laser provides superior healing, less pain, and better bleeding control compared to electrosurgery.

Descripción general del estudio

Descripción detallada

Participant Allocation: Participants meeting the inclusion criteria (aged 3-6, diagnosed with Kotlow grade 3 or 4 ankyloglossia) are randomly assigned to one of two groups using a simple randomization method (drawing lots):

  • Group 1 (Laser Group): Lingual frenectomy performed using a 940 nm Diode Laser (Epic X, Biolase) with a power of 1W (average) and 2W (peak) in pulsed mode (CP2).
  • Group 2 (Electrosurgery Group): Lingual frenectomy performed using a high-frequency electrosurgical unit (ERBE-VIO 100C) in continuous contact mode.

Surgical Procedure: Both groups follow a standardized surgical protocol:

  • Anesthesia: Local anesthesia with 2% Lidocaine/Adrenaline (0.45 ml).
  • Technique: Transverse incision without suturing or muscle dissection to release the lingual frenum.
  • Safety Measures: Use of protective eyewear for the laser group and electrode grounding pads for the electrosurgery group.

Data Collection and Blinding:

  • Blinding: This is a single-blind study where the participants and their guardians are unaware of the assigned treatment group. The evaluator measuring post-operative outcomes is also blinded to the surgical method used.
  • Follow-up Schedule: Evaluations are conducted at five specific intervals:

    • Baseline (T0): Pre-operative measurements.
    • Post-operative: At 24 hours (T1), 3 days (T2), 1 week (T3), and 1 month (T4).

Evaluation Criteria:

  • Wound Healing: Assessed by the Early Wound Healing Score (EHS), focusing on re-epithelialization (CSR), haemostasis (CSH), and inflammation (CSI).
  • Pain Intensity: Self-reported by patients using the Wong-Baker FACES Pain Rating Scale.
  • Tongue Function: Measuring the increase in free tongue length (mm) using a Quick Tongue-Tie (QTT) tool.

Experimental: Diode Laser Group
Patients in this group undergo lingual frenectomy using a 940 nm diode laser (Epic X, Biolase). The procedure is performed using a transverse incision technique without suturing. Laser settings include an average power of 1W, peak power of 2W in pulsed mode (CP2), and a 940 nm wavelength.

Comparador activo: Electrosurgery Group
Patients in this group undergo lingual frenectomy using a high-frequency electrosurgical unit (ERBE-VIO 100C). The procedure follows the same transverse incision protocol without suturing as the experimental group.
Lingual frenectomy performed using a high-frequency electrosurgical unit (ERBE-VIO 100C). The procedure follows a standardized transverse incision protocol without suturing. A grounding pad (electrode) is applied to the patient's body to complete the circuit. This serves as the active comparator representing the conventional surgical method at the hospital.

¿Qué mide el estudio?

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Early Wound Healing Score (EHS)
Periodo de tiempo: 24 hours (T1), 3 days (T2), and 1 week (T3) post-surgery.
The EHS is used to evaluate the early healing of periodontal soft tissue wounds. It is the sum of three components: Clinical Signs of Re-epithelialization (CSR), Clinical Signs of Haemostasis (CSH), and Clinical Signs of Inflammation (CSI). The total score ranges from 0 to 10, where a higher score indicates better and faster wound healing (10 being perfect healing).
24 hours (T1), 3 days (T2), and 1 week (T3) post-surgery.
