冲牙器改善冠桥修复体牙周健康的效果评价

Evaluation of oral irrigator on improving the periodontal health of the crown bridge prosthesis

目的探讨冠桥修复体患者使用冲牙器后对牙周健康的影响。方法将接受冠桥修复的患者30例随机分为2组,每组15例。试验组为修复体戴入时刷牙加冲牙器使用组,对照组为修复体戴入后单纯刷牙组。分别在戴入时及戴入后3个月检查牙周临床指标(包括菌斑指数、牙龈指数、龈沟出血指数)和牙周袋内硫化物,并将测量结果应用SPSS18.0软件作统计学分析。结果修复体戴入时,试验组和对照组牙周指数和牙周袋内硫化物值差异无统计学意义(P>0.05)。戴入后3个月,试验组菌斑指数、牙龈指数、龈沟出血指数和牙周袋内硫化物值分别为1.78±0.50,2.25±0.52,1.40±0.52,1.01±0.50,对照组菌斑指数、牙龈指数、龈沟出血指数和牙周袋内硫化物值分别为2.13±0.70,2.48±0.48,1.74±0.64和1.58±0.70,且试验组所有指标均显著低于对照组(P<0.05)。结论使用口腔冲牙器能够有效改善冠桥修复体牙周健康。

Objective To explore the effect of oral irrigator on the periodontal health of the crown bridge prosthesis. Methods Thirty volunteers with crown bridge prosthesis were randomly divided into two groups（ n = 15）. The experimental group used both the oral irrigator and the toothbrush,while the control group used only the toothbrush. Clinical periodontal indices,including plaque index（ PLI）,gingival index（ GI）,sulcus bleeding index（ SBI） and periodontal pocket sulfide（ PS） were examined at two different time points： before treatment and 3 months after treatment. The data of the two groups were statistically analyzed with the SPSS18.0 software package. Results Before treatment,the periodontal indices and PS had no difference between the two groups（ P〉0. 05）. After 3months,PLI,GI,SBI and PS in the experimental group were（ 1.78±0.50）,（ 2.25±0.52）,（ 1.40±0.52）,（ 1.01±0.50） respectively,while PLI,GI,SBI and PS in control group were（ 2.13±0.70）,（ 2.48±0.48）,（ 1.74±0.64） and（ 1.58±0.70）. All indices in the experimental group were lower than those in the control group（ P0.05）. Conclusion The use of oral irrigator can effectively improve the periodontal health of crown bridge prosthesis.
