| 摘 要： | 患实验性牙龈炎的大鼠牙龈（６例）经脉冲掺钕钇铝柘榴石激光（Ｎｄ：ＹＡＧ激光）照射后进行光镜及超微结构观察。目的在于了解低能量Ｎｄ：ＹＡＧ激光照射对牙龈炎症的治疗作用。炎症牙龈经输出能量为１．５Ｗ，脉冲数为２０ＰＰＳ的激光照射后与对照组相比较，形态学上有如下变化：上皮细胞无变性；牙龈上皮层数较炎症时减少；上皮下炎细胞浸润明显减少；上皮细胞间隙变小；上皮下结缔组织内产生大量的排列致密的胶原纤维。结果提

| Abstract: | Gingival tissues of rats with experimental gingivitis were studied following a pulsedneodymium yttrium-aluminum-garnet (Nd:YAG)laser irradiation. The purpose of this study was toassess the effectiveness of the Nd:YAG laser in the treatment of gingival inflammation. The re-surts showed that the inflammatory infiltration and the defects of epithelial and underlying conne-ctive tissues caused by the gingivitis reduced obviously after laser irradiation as determined histo-logically and ultrastructurally.The study indicates that the pulsed Nd: YAG laser may be a safeand powerful methed of treatment for periodontal inflammation. |
