The aim of this study is to investigate the efficacy of delivering low-level laser therapy (LLLT) in the management of dry socket at University Dental Hospital Sharjah.
Forty-five patients with dry socket were divided into two treatment groups. Group I dry socket patients (n = 30) received conventional treatment while group II patients (n = 15) were irradiated with LLLT at a setting of 200-mW, 6-J, continuous-wave mode using an R02 tipless handpiece (Fotona Er:YAG, Europe), on the buccal, lingual, and middle surfaces of the socket for 30 s from a delivery distance of 1 cm. Pain score and quantification of granulation tissue in the socket were recorded at 0, 4, and 7 days post-dry socket treatment.
Results showed that the LLLT-irradiated group II sockets showed a much lower VAS pain score of 1-2 as early as day 4, and a richer amount of granulation tissue compared to the conventional treated group I socket. The amount and rate of granulation tissue formation in the dry socket are inversely proportional to the pain score showing significant clinical effectiveness of LLLT on promoting the healing of the dry socket, with improvement in symptoms (P = .001). Conventionally treated dry sockets take at least 7 days to match the effective healing of an LLLT-irradiated dry socket.
LLLT irradiation influences biomodulation of dry socket healing by dampening inflammation, promoting vascularization, stimulating granulation, and controlling pain symptoms.
LLLT may be an additional effective tool for managing dry sockets in general dental practice.
本研究旨在探讨低水平激光疗法(LLLT)在沙迦大学牙科医院干槽症管理中的疗效。
将 45 例干槽症患者分为两组。第 I 组干槽症患者(n=30)接受常规治疗,第 II 组患者(n=15)采用 200-mW、6-J、连续波模式的 R02 无尖端手柄(Fotona Er:YAG,欧洲)照射牙槽窝颊、舌、中面,每个部位照射 30 秒,从 1cm 的输送距离进行照射。在干槽症治疗后 0、4 和 7 天记录疼痛评分和牙槽窝内肉芽组织的量化。
结果表明,LLLT 照射的第 II 组牙槽窝在第 4 天疼痛评分仅为 1-2,并且与常规治疗的第 I 组牙槽窝相比,肉芽组织量更多。干槽症中肉芽组织的数量和形成速度与疼痛评分呈反比,表明 LLLT 在促进干槽症愈合方面具有显著的临床效果,可改善症状(P=0.001)。常规治疗的干槽症至少需要 7 天才能达到 LLLT 照射干槽症的有效愈合。
LLLT 照射通过抑制炎症、促进血管生成、刺激肉芽组织形成和控制疼痛症状来影响干槽症愈合的生物调节。
LLLT 可能是普通牙科实践中治疗干槽症的一种额外有效工具。
