研究目的
To evaluate the efficacy of Laser tissue bonding (LTB) by comparing with the routinely used sutures for closure of intraoral surgical wounds after periodontal surgery.
研究成果
LTB was effective in achieving wound closure with no morbid complications associated, showing superiority in terms of vascularisation, wound healing scores, time consumption, and microbial colonization compared to conventional suturing.
研究不足
The study was limited by the small sample size and the short follow-up period. Further long-term randomized controlled trials are needed to validate the efficacy of LTB.
1：Experimental Design and Method Selection:
A randomized, single-blinded clinical trial was conducted to compare LTB with conventional suturing for wound closure after periodontal surgery.
2：Sample Selection and Data Sources:
Seventeen patients with bilateral periodontal pockets requiring flap surgery were selected.
3：List of Experimental Equipment and Materials:
An 810 diode laser (Picasso, Dentsply), Alburel (20% albumin), and indocyanine green dye (Aurogreen from Aurolab, India) were used.
4：Experimental Procedures and Operational Workflow:
Modified flap surgery was performed, with LTB on one side and conventional suturing on the other. Laser welding was performed with a power of
5：5 W in continuous waveform. Data Analysis Methods:
Statistical analysis was performed using SPSS 20 version, with independent 't' test and repeated measures ANOVA.
