The aim of this study was to evaluate the effects of helium-neon and gallium-aluminum-arsenide lasers with various doses on bone healing following tooth extraction.
Maxillary right incisor teeth of 30 female albino Wistar rats were extracted. Five groups were established: four groups treated with helium-neon or gallium-aluminum-arsenide lasers and a control group. Both laser groups' rats received energy doses of 6 J/cm and 10 J/cm for 7 days. At the end of 30 days, all subjects were sacrificed for histological and morphological evaluations.
Laser groups showed faster bone healing and gallium-aluminum-arsenide lasers increased vascular immunoreactivity. The most widespread organized bone formation in the extraction socket was observed in the gallium-aluminum-arsenide laser group with the energy dose of 10 J/cm (p < 0.05).
This study demonstrated that low-level laser therapies were effective on alveolar bone healing and that an energy dose of 10 J/cm did not have an inhibition effect on bone regeneration.
本研究旨在评估氦氖和砷化镓铝激光在不同剂量下对拔牙后骨愈合的影响。
切除 30 只雌性白化 Wistar 大鼠的右上切牙。建立了五组：四组用氦氖或砷化镓铝激光治疗，一组为对照组。两组激光组的大鼠分别接受 6 J/cm 和 10 J/cm 的能量剂量照射 7 天。30 天后，所有实验动物均处死进行组织学和形态学评价。
激光组的骨愈合速度较快，砷化镓铝激光增加了血管免疫反应性。在能量剂量为 10 J/cm 的砷化镓铝激光组中，观察到牙槽窝内最广泛的有组织骨形成（p<0.05）。
本研究表明，低水平激光疗法对牙槽骨愈合有效，且 10 J/cm 的能量剂量不会对骨再生产生抑制作用。
