本研究的目的是观察 Nd:YAG 激光对污染的根管和牙本质小管的抗菌作用。样本接种了血链球菌 (NCTC 7853) 和中间普雷沃氏菌 (NCTC 93336)，并测试了 Nd:YAG 激光对这些牙齿的效果。用1.8 W和2.4 W Nd:YAG激光照射标本30 s，在光学显微镜下观察小管中细菌的存在。 1.8 W 激光对接种血链球菌的切片中 86.3% 的小管进行了灭菌，而 2.4 W 激光对 98.5% 的切片进行了灭菌。两种激光功率都对所有接种中间假单胞菌的样品进行了灭菌。扫描电子显微镜观察支持了光学显微镜的发现。
The antibacterial effects of the Nd:YAG laser on contaminated root canals and dentinal tubules were observed as the aim of this study. The samples were inoculated with Streptococcus sanguis (NCTC 7853) and Prevotella intermedia (NCTC 93336), and the effects of Nd:YAG laser were tested on these teeth. The specimens were lased with 1.8 W and 2.4 W Nd:YAG laser for 30 s, and the presence of bacteria in tubules was observed under light microscopy. The 1.8 W laser sterilized the tubules in 86.3% of sections inoculated with S. sanguis, whereas 2.4 W laser sterilized in 98.5% of the sections. Both laser powers sterilized all samples inoculated with P. intermedia. The scanning electron microscopic observations supported the light microscopic findings.
