背景:本研究旨在比较使用外科手术刀与445nm和980nm二极管激光进行骨切除术的术中和术后并发症。
方法:这项随机对照临床试验对174例需要上颌唇切除术的患者进行。在完成固定正畸治疗和上颌骨一期闭合后,这些患者被随机分为三组(n=58):第1组(通过445nm二极管激光进行静脉切除术,连续波,1.5W),第2组(通过980nm激光进行全系切除术,连续波,1.7W),对照组(手术刀V-Y成形术)。术中出血,咀嚼和说话时感到不适,疼痛,并立即比较各组的组织愈合情况,在术后7天和30天使用Kruskal-Wallis,Mann-Whitney,和卡方检验。
结果:第1组的疼痛评分明显低于第2组(即刻和第7天,P<0.05)。与第2组相比,第1组观察到第7天和第30天明显更快的组织愈合(P<0.05)。在术中出血量较低方面,第1组优于对照组,咀嚼和说话时的不适(立即和第7天),降低疼痛(立即和第7天),和组织愈合(第7天)(均P<0.05)。2组在术中出血量减少方面明显优于对照组,咀嚼和说话时的不适(立即和第7天),和更好的组织愈合(第7天)(均P<0.05)。
结论:结论:与手术刀相比,二极管激光全线切割术的术中和术后并发症显著降低.此外,与980nm二极管激光器相比,445nm二极管激光器显示出明显的优越效果。

BACKGROUND: This study aimed to compare the intra and postoperative complications of
frenectomy procedure with a surgical scalpel versus 445 nm and 980 nm diode lasers.
METHODS: This randomized controlled clinical trial was conducted on 174 patients requiring maxillary labial
frenectomy. After completion of fixed orthodontic treatment and primary closure of maxillary diastema, the patients were randomly assigned into three groups (n = 58): group 1 (
frenectomy via 445 nm diode laser, continuous-wave, 1.5 W), group 2 (
frenectomy via 980 nm laser, continuous-wave, 1.7 W), and control group (V-Y plasty technique via scalpel). Intra-operative bleeding, discomfort in chewing and speaking, pain, and tissue healing were compared among the groups immediately, at 7 and 30 days postoperatively using the Kruskal-Wallis, Mann-Whitney, and Chi-square tests.
RESULTS: Pain scores were significantly lower in group 1 compared to group 2 (immediately and day 7, P < 0.05). Significant faster tissue healing at days 7 and 30 were observed in group 1 compared to group 2 (P < 0.05). Group 1 was superior to the control group regarding lower intraoperative bleeding, discomfort in chewing and speaking (immediately and day 7), lower pain (immediately and day 7), and tissue healing (day 7) (P < 0.05 for all). Group 2 was significantly superior to the control group in lower intraoperative bleeding, discomfort in chewing and speaking (immediately and day 7), and better tissue healing (day 7) (P < 0.05 for all).
CONCLUSIONS: In conclusion, diode laser
frenectomy resulted in significantly lower intra and postoperative complications compared to the scalpel. Moreover, 445 nm diode laser showed significantly superior effects compared to 980 nm diode laser.
BACKGROUND: The study protocol was registered on 29.10.2022 at the Iranian Registry of Clinical Trials ( www.irct.ir ) (registration number: IRCT20220630055326N1).
