摘　　要：目的比较牙周翻瓣术与二次龈下刮治和根面平整术(scaling and root planing,SRP)治疗慢性牙周炎的临床疗效。方法选取牙周基础治疗6w后牙周探诊深度为5～7mm的单根牙117颗作为研究对象,同一患者的左右两侧牙随机分为二次SRP组和改良Widman翻瓣组。二次SRP组患者在局麻下对纳入的患牙用赛特力超声治疗机和Gracey刮治器进行龈下刮治和根面平整术,翻瓣组患者在局麻下行改良Widman翻瓣术。治疗后3、6个月对两组患者进行复诊,并对患者的受试牙进行牙周专业检查,记录探诊出血(BOP)、探诊深度(PD)、临床附着水平(CAL)及牙龈退缩(GR)。结果二次SRP组和改良Widman翻瓣组治疗后6个月患牙的BOP阳性率、PD、CAL、GR分别为16.92%、(2.82±0.74)mm、(5.05±1.02)mm、(2.02±0.60)mm和11.60%、(2.54±0.49)mm、(4.90±0.83)mm、(2.35±0.67)mm,两组治疗后6个月各项指标与治疗前比较差异均有统计学意义(P<0.05)。治疗后6个月两组间BOP阳性率、PD及CAL比较差异无统计学意义(P>0.05),但改良Widman翻瓣组GR明显高于二次SRP组(P<0.05)。结论对于单根牙,二次SRP和改良Widman翻瓣术可达到相同的治疗效果,但翻瓣术后的牙龈退缩较二次SRP明显。Objective To compare the clinical effect between periodontal flap surgery and repeated perio dontal scaling and root planing （scaling and root planing, SRP） of chronic periodontitis. Methods Sam ples of 117 single-rooted teeth, which still had deep pockets from 5 mm to 7 mm at 6 weeks after initial therapy were selected. The right and left sides of the same patients teeth were randomly divided into repeated SRP group and modified Widman flap surgery group. The repeated SRP group of patients were un- dertaken scaling and root planing with local anesthesia on the troubled teeth employing Sately ultrasound therapy machines and Gracey curette Patients of the modified Widman flap surgery modified Widman flap surgery under local anesthesia. Patients of both groups returne months for probing dep pr th gr d oup were received visit after 3 and 6 ofessional periodontal examination. Recorded and compared bleeding on probing （BOP）, （PD）, clinical attachment level （CAL） and gingival recession （GR）. Results BOPG, PD, GR, CAL values in two groups at 6 months after therapy were respectively 16.92%, （2.82±0.74） mm, （5.05±1.02） mm, （2.02±0.60） mm and 11.60%, （2.54±0.49） mm, （4. 90±0. 83） mm, （2.35i±0.67） mm, which were significantly improved than those at baseline in both groups （P〉0.05）. However, BOP%, PD and CAL values at final examination showed no significant difference between two groups （P ）0.05）. Both treatments caused gingival recession after surgery, but gingival recession of the modified Widman flap surgery group was significantly higher than that of those received the repeated SRP group （P〈0.05）. Conclusion In our study, both treatments showed similar effects in improving clinical periodon- tal parameters of single-rooted teeth, and surgery produced more gingival recessions than the repeated SRP.
