摘　　要：目的：通过临床试验，研究Nd：YAG激光用于乳牙活髓切断术的有效性，为临床行乳牙活髓切断术提供一种有效的新方法。方法选择3～6岁乳牙深龋及早期牙髓炎患儿189例，将实验牙随机分为激光组和对照组。激光组给予40 Hz，2 W，50 mJ的能量照射乳牙切髓断面，对照组给予生理盐水、双氧水冲洗牙髓断面，消毒棉球压迫止血。治疗后，分1，3，6个月三个时间段随访并行X片复查。结果激光组在每个时间点的口内检查和X线表现均优于对照组。结论 Nd：YAG激光照射乳牙切髓断面，能有效地杀菌、止血。同时可有效地应用于乳牙活髓切断术中。ObjectiveThe purpose of this study was to compare clinical effects of Nd：YAG laser pulpotomy to formocresol pulpotomy on human primary teech. An effective new method for pulpotomy was applied.Methods189 cases of primary teeth with deep caries or early pulpitis were selected for this study. These teeth were divided into the laser group and the control group randomly. After pulpotomy, every stump of laser group was exposed to Nd：YAG laser with output of 40 Hz, 2 W, 50 mJ. And each of the control group was irrigated with Stroke-physiological caline solution（SPSS） and Hydrogen Peroxide,then staunched with pressure. 189 teeth in two groups were to be followed up clinically and radiographicaly at 1, 3, 6 months. ResultsThe rapeutical effects of the experimental group were better than that of the control group in clinical and radiographic examination at each time point.ConclusionNd：YAG laser,can effectively sterilize and staunch. Nd： YAG laser is an effective method for primary teeth pulpotomy.
