摘要：

目的：应用高频电刀、CO₂激光、微波热凝及传统牙龈成形术治疗由不良烤瓷冠引起的牙龈增生性病变，观察治疗效果，探讨其临床应用价值。方法：将 148例不良烤瓷冠引起的牙龈增生性病变患者随机分为高频电刀组、CO₂激光组、微波热凝组及传统牙龈成形术组，每组各37例，分别应用上述4种方法进行治疗，恢复重建牙龈生理功能和外观，比较各组患者手术时间、术中失血量、创面愈合时间、临床疗效及美学效果。结果：①与传统牙龈成形术组比较，高频电刀组、CO₂激光组及微波热凝组患者手术时间短、术中失血量少、愈合快、感染率低（P<0.01或P<0.05)。②4组患者术后牙龈指数（GI）、龈沟出血指数（SBI）及改良出血指数（mBI）与术前比较明显降低(P<0.01)，且高频电刀组、CO₂激光组及微波热凝组患者术后GI明显低于传统牙龈成形术组（P<0.05)。③高频电刀组、CO₂激光组及微波热凝组患者1年后有效率分别为97.3%、94.6%及97.3%，组间比较差异无统计学意义（χ2 =0.34，P>0.05），但均高于传统牙龈成形术组（89.2%）（P<0.05）。结论：采用高频电刀、CO₂激光、微波热凝治疗不良烤瓷冠引起的牙龈增生性病变效果确切，效果优于传统牙龈成形术。

Abstract:

Abstract:Objective To study the clinical effects of high-frequency electric knife,CO₂ laser,microwave technique and conventional surgery in treating gingival hyperplasia caused by ill porcelain-fused-to-metal (PFM) and explore the values of their chinical applications.Methods Different types and various degrees of 148 patients with gingival hyperplasia were randomly divided into high-frequency electric knife group,microwave technique group,CO₂ laser group,and conventional surgery group,37 cases in each group.The patients were treated with the 4 kinds of methods mentioned above.Then gingiva was removed and its form was repaired to restore and reconstruct the periodontal physiological function and appearance.Results ①Compared with conventional surgery group,in high-frequency electric knife,CO₂ laser,microwave technigue groups,the operative time was shorher,the intraoperative blood loss was lower,the wound healing time was shortened,and the wound infection rates were decreased(P<0.05 or P<0.01).②The gingival indexes(GI),sulcus bleeding indexes(SBI) and modified bleeding indexes(mBI) in 4 groups after operation were significantly decreased compared with before operation(P<0.01).The GI in high-frequency electric knife group,CO₂ laser group,and microwave technique groups after operation were significntaly lower than that in conventional surgery group (P<0.05).③ The one-year efficiencies in high-frequency electric knife group,CO₂ laser group,and microwave technique group were 97.3%,94.6%,and 97.3%,there were no significant differences between three groups (χ2 = 0.34,P> 0.05);but they were sifnificantly higher than that in conventional surgery group (89.2%) (χ2 = 0.54,P<0.05).Conclusion High-frequency electric knife,CO₂ laser,and microwave technique can be effective in the treatment of gingival hyperplasia,and superior to conventional surgery.
