摘要

Conventional suturing has inherent shortcomings like inflammation, wicking effect, and additional appointments for removal. Various suture alternatives have been described in the scientific literature with satisfactory results. This study was planned to evaluate and compare the clinical efficacy of Laser Tissue Welding (LTW) and conventional suturing after periodontal surgery. Patients indicated for periodontal flap surgery in bilateral quadrants were selected and randomly allocated to the two study groups. In Group I (Control), flap approximation was achieved with 3 − 0 black silk sutures. In Group II (Test), a 20% albumin and indocyanine green mixture was applied, and laser application was done at 1.5 W in a continuous waveform to achieve a welded tissue. Clinical parameters were assessed using the Plaque Index, Early Wound Healing Index, and Modified Sulcular Bleeding Index, which were recorded at baseline, 3rd, 7th, and 14th postoperative days. Visual Analogue Scale (VAS) was used to measure postoperative pain at the 3rd ,7th, and 14th day, and to estimate operative time, at the time of surgery. The intergroup comparison has demonstrated significant improvement with LTW in all clinical parameters, with reduced operative time compared to sutured sites. LTW can be used as an efficient suture alternative technique in periodontal surgeries.
