The study investigated the use of LED light therapy in tooth extraction procedures, focusing on its effects on hemostasis and socket healing. LED therapy, typically used for composite resin polymerization, was explored for its potential to induce hemostasis through photo-thermo-coagulation.
Fifty patients with bilateral extractions were selected. One socket received LED therapy (480 nm wavelength, 20 s), the other served as control. Bleeding cessation time and socket healing after 72 h were evaluated.
The LED-treated group showed significantly faster bleeding cessation (30.80 ± 5.22 s) compared to the control group (161.04 ± 25.69 s). After 72 h, the LED-treated sockets exhibited better healing than the control group.
The study suggested LED photocoagulation promotes rapid hemostasis and accelerates periodontal tissue healing. The mechanism involves vascular spasm, platelet aggregation, and coagulation. LED therapy shows promise as an alternative to traditional hemostatic methods, potentially reducing the need for sutures or local hemostatic agents.
LED light therapy demonstrates significant potential in improving post-extraction hemostasis and healing, offering a novel approach in dental procedures and periodontal photo-engineering.
本研究调查了LED光疗法在拔牙手术中的应用，重点关注其对止血和牙槽窝愈合的影响。通常用于复合树脂聚合的LED疗法，因其通过光热凝固诱导止血的潜力而被探索。
选择50例双侧拔牙患者。一个牙槽窝接受LED疗法（波长480nm，持续20秒），另一个作为对照。评估止血时间和72小时后的牙槽窝愈合情况。
与对照组（161.04±25.69秒）相比，LED治疗组的止血速度明显更快（30.80±5.22秒）。72小时后，接受LED治疗的牙槽窝比对照组愈合得更好。
该研究表明LED光凝能促进快速止血并加速牙周组织愈合。其机制包括血管痉挛、血小板聚集和凝血。LED疗法有望成为传统止血方法的替代方法，可能减少缝合或局部止血剂的使用。
LED光疗法在改善拔牙后止血和愈合方面显示出巨大潜力，为牙科手术和牙周光工程提供了一种新方法。
