About this study

Official title: Clinical Outcomes and Local Molecular Biomarker Changes in Gingival Crevicular Fluid Following Diode Laser Versus Conventional Frenectomy in Children: A Randomized Clinical Trial

This prospective, randomized, open-label, parallel-group clinical trial aims to compare diode laser frenectomy with conventional scalpel frenectomy in children aged 8-12 years with a clinical indication for maxillary labial frenectomy. Participants will be randomly allocated in a 1:1 ratio to undergo either diode laser or conventional scalpel frenectomy. Postoperative pain, wound healing, analgesic requirement, feeding difficulty, and daily comfort will be evaluated during follow-up. Gingival crevicular fluid samples will be collected at baseline and on postoperative Days 3, 7, and 14 to assess local molecular changes associated with inflammation, tissue injury, wound healing, and periodontal-alveolar remodeling using RT-qPCR.

Read the detailed description

This study is a prospective, randomized, open-label, two-arm, parallel-group clinical trial designed to compare the postoperative clinical and local molecular responses following diode laser and conventional scalpel frenectomy in children.

Children aged 8-12 years with a clinical indication for maxillary labial frenectomy who meet the eligibility criteria will be randomly allocated in a 1:1 ratio to either the diode laser frenectomy group or the conventional scalpel frenectomy group using computer-generated randomization. Because the two surgical procedures are visibly and technically different, masking of the treating clinician and participants is not feasible.

Clinical evaluations will be performed at baseline and during postoperative follow-up. Postoperative pain will be assessed using a 0-10 Visual Analog Scale (VAS), and wound healing will be evaluated using the Landry, Turnbull and Howley Wound Healing Index. Analgesic requirement, feeding difficulty, daily comfort, and other clinical healing findings will also be recorded. Standardized intraoral photographs obtained during follow-up will provide supportive assessment of postoperative wound healing.

Gingival crevicular fluid samples will be collected from the gingival sulcus adjacent to the maxillary central incisors at baseline (Day 0) and on postoperative Days 3, 7, and 14. Two sterile paper points will be used at each sampling time point. Samples will be transferred to RNase-free tubes, transported under cold-chain conditions, and stored at -80°C until molecular analysis.

RNA isolation, complementary DNA synthesis, and RT-qPCR analyses will be performed to evaluate gene expression changes related to inflammation, tissue injury, wound healing, and local periodontal-alveolar remodeling. Planned molecular targets include IL1B, TNF, IL8, FGF2, TGFB1, an LDH metabolism-related target gene, and SOST. GAPDH and ACTB will be used as reference genes. SOST will be evaluated as a secondary exploratory marker of local periodontal-alveolar remodeling.

Changes in clinical and molecular outcomes will be evaluated over time and between treatment groups, including assessment of group, time, and group-by-time effects.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Diode Laser FrenectomyProcedure or surgery

    Maxillary labial frenectomy will be performed using a Woodpecker LX16 Plus diode laser under standardized clinical conditions. The procedure will be carried out by the Department of Periodontology. Laser parameters, including wavelength, power, operating mode, fiber diameter, and application technique, will be standardized according to the final study protocol.

  • Conventional Scalpel FrenectomyProcedure or surgery

    Maxillary labial frenectomy will be performed using a conventional surgical scalpel under standardized clinical conditions. The procedure will be carried out by the Department of Periodontology according to the study protocol.
