目的近年来，掺铒钇铝石榴石（Er：YAG）激光在牙周治疗中的应用越来越多。在这项回顾性研究中，我们评估了一种新型的袋治疗，使用Er：YAG激光结合传统的机械洁治和根面平整治疗（Er：YAG激光辅助牙周袋综合治疗）的安全性和有效性。方法2006 ~ 2009年对29例老年牙周病患者40个牙周袋深度≥ 5 mm的部位进行刮匙联合Er：YAG激光治疗。用刮匙清创牙根后，对牙根面进行激光照射。然后，用刮匙和激光彻底清除牙龈内表面和骨表面/现存骨缺损内的炎症结缔组织。此外，在大多数情况下，还使用激光去除囊袋入口处的外上皮和凝血。在治疗前和治疗后3、6和12个月评价临床参数。结果Er：YAG激光辅助囊袋治疗术能安全、彻底地清创囊袋，大多数病例临床症状改善良好，无任何不良反应和并发症。1年后，探测囊袋深度从6.4 +/- 1.4 mm显著降低至3.5 +/- 1.3 mm（p < 0.001，减少3.0 mm），临床附着水平从7.5 +/- 1.6 mm显著降低至5.2 +/- 1.9 mm（p < 0.001，增加2.3 mm）。结论Er：YAG激光辅助治疗是一种微创的不翻瓣手术，可用于治疗残留囊袋。
Objectives Recently, the application of erbium-doped yttrium aluminum garnet (Er:YAG) laser has been increasing in periodontal therapy. In this retrospective study, we evaluated the safety and effectiveness of a novel pocket therapy using Er:YAG laser in combination with conventional mechanical scaling and root planing treatment (Er:YAG laser-assisted comprehensive periodontal pocket therapy). Methods Forty sites in 29 elderly patients having residual periodontal pockets of >= 5 mm depth were treated by curette and Er:YAG laser from 2006 to 2009. After root debridement by curette, laser irradiation was performed on the root surfaces. Then, inflamed connective tissue on the inner gingival surface and on the bone surface/within extant bone defects was thoroughly debrided by curette and laser. Furthermore, in most cases, removal of the outer epithelium and coagulation of the blood clot in the pocket entrance were additionally performed with laser. Clinical parameters were evaluated before and 3, 6, and 12 months after treatment. Results With Er:YAG laser-assisted pocket therapy, debridement of pockets was thoroughly and safely performed, and favorable clinical improvements were observed in most cases, without any adverse side effects and complications. After 1 year, probing pocket depth significantly decreased from 6.4 +/- 1.4 to 3.5 +/- 1.3 mm (p < 0.001, 3.0 mm reduction), and clinical attachment level significantly decreased from 7.5 +/- 1.6 to 5.2 +/- 1.9 mm (p < 0.001, 2.3 mm gain). Conclusion The results of this study indicate that Er:YAG laser-assisted therapy is useful for the treatment of residual pockets as a minimally invasive flapless surgery.
