AbstractObjective The aim of the study was to assess the clinical use of Er:YAG laser in the preparation of the teeth with subgingival wedge-shape defects.Methods The data of twenty patients were collected. All patients had at least two teeth with similar subgingival wedge-shape defects. In the control group, cavities were prepared with bur, gingiva was removed by high frequency electrotome. On the contrast, the cavities' preparation and gingivectomy were performed by the laser in the experimental group. The degree of the patients' uncomfortable feel was recorded with VAS, and all patients were followed up for 12 months after surgery.Results The average VAS value of the experimental group (42.3±12.1) was statistically lower than that of the control group (61.1±17.0) (P<0.01). One week later, one case in the control group suffered from gingival recession and dental hypersensitiveness. Twelve months later, the margins of two and three cases were unsealed and stained respectively in the experimental group and the control group (P>0.05).Conclusion Using Er:YAG laser irradiation in cavities' preparation and gingivectomy for the teeth with subgingival wedge-shape defects can significantly reduce the uncomfortable feel during the treatment process, and doesn't adversely affect the qualities of restorations.
目的 评价Er:YAG激光在治疗龈下楔状缺损中的应用.方法 选择有两个洞缘位于龈下1mm~2mm的楔状缺损患牙的患者共20例.对照组以车针预备窝洞,电刀切除牙龈的方法进行牙体预备,实验组以Er:YAG激光预备窝洞并同时切除牙龈的方法完成预备.以VAS评分记录术中不舒适程度,术后随访12个月检查充填体情况.结果 试验组VAS平均值为42.3±12.1,对照组VAS平均值为61.1±17.0,两组间差异有显著性(P<0.01).术后1周,对照组有1例发生龈退缩.12个月,试验组和对照组分别有2例和3例出现边缘不密合和边缘着色(P>0.05).结论 激光行龈下楔状缺损牙体预备的方法可以有效减轻术中不适,对充填体质量无副作用.
