This study aimed to evaluate the effect of low-level laser therapy and hyaluronic acid injection in intraoral wound healing. Eighteen Wister albino rats were included in this study, and they were randomly divided into 3 groups; in the first group, a wound was created with a 450-nm diode laser in the buccal mucosa without any further intervention, and in the second group, the wound was created with a 450-nm diode laser followed by non-cross-linked hyaluronic acid injection. In the third group, the wound was created with a 450-nm diode laser followed by low-level laser therapy with a 650-nm diode laser and hyaluronic acid injection. Biopsies were taken at different intervals (baseline, third day, and seventh day) for evaluation of the wound healing using hematoxylin stain, Masson trichrome stain, and immunohistochemical study for CD34 analysis. Group 3 showed significant results compared with the other groups on the third and seventh postoperative days, with increased collagen production and better tissue organization with abundant angiogenesis. Low-level laser therapy in addition to hyaluronic acid injection in incisions created with lasers shows promising results in wound healing and may quicken the healing process.
本研究旨在评估低强度激光疗法和透明质酸注射对口腔内伤口愈合的影响。本研究纳入了18只Wister白化大鼠,并将它们随机分为3组;在第一组中,使用450纳米二极管激光在颊黏膜上造成伤口,不进行任何进一步干预;在第二组中,先用450纳米二极管激光造成伤口,然后注射非交联透明质酸。在第三组中,先用450纳米二极管激光造成伤口,然后用650纳米二极管激光进行低强度激光疗法并注射透明质酸。在不同时间间隔(基线、第三天和第七天)取活检组织,使用苏木精染色、马松三色染色以及用于CD34分析的免疫组织化学研究来评估伤口愈合情况。与其他组相比,第三组在术后第三天和第七天显示出显著结果,胶原蛋白生成增加,组织组织化更好,血管生成丰富。在用激光造成的切口处,除注射透明质酸外进行低强度激光疗法,在伤口愈合方面显示出有前景的结果,并且可能加快愈合过程。
