摘要
目的:通过在肾虚型牙周炎大鼠建模过程中给予电针刺激"足三里"穴与非经非穴点,观察牙槽骨吸收值的变化,探讨电针"足三里"穴对大鼠牙周炎形成的预防作用。方法:36只SD大鼠随机分为对照组(N组)、足三里组(P1组)和非经非穴组(P2组),3组均以牙颈部钢丝结扎+肌注醋酸泼尼松龙法制备肾虚型牙周炎大鼠模型。从开始制备模型起,N组不作任何处理,P1组同时给与电针刺激"足三里"穴,P2组则电针刺激"足三里"穴旁外1cm非经非穴点。结果:实验开始1、2、3周时各组牙槽骨吸收值分别为N组:(2.92±0.42)mm、(4.44±0.30)mm、(4.72±0.27)mm,P1组:(0.91±0.58)mm、(1.46±0.93)mm、(2.08±0.77)mm,P2组:(2.84±0.65)mm、(4.21±0.42)mm、(4.51±0.19)mm。1周时各组牙槽骨吸收值之间无差别,2周、3周时P1组牙槽骨吸收值均分别小于N组、P2组(P<0.05),N组、P2组之间无差别。结论:电针"足三里"穴可以减轻肾虚型牙周炎大鼠在建模过程中牙槽骨吸收程度,电针非经非穴点无此作用。
Objective： To observe changes of alveolar bone absorption values and to discuss the preventive action of EA at Zusanli on periodontitis. Methods： 36 rats were randomly divided into the control group （N group）, the Zusanli group （P1 group） and the Feijing Feixue group （P2 group）, three groups were given Tooth neck ligation ＋prednisolone acetate injection, while the P1 group was given EA at Zusanli more, the P2 group was given EA at Feijing Feixue. Results： The alveolar bone absorption values in the first, second, third week in the N group were （2.92±0.42） mm, （4.44±0.30） rnm, （4.72±0.27） rnm; while in the P1 group were （0.91±0.58） ram, （1.46±0.93） mm, （2.08±0.77） mm; in the P1 group were （2.84±0.65） mm, （4.21±0.42） mm, （4.51 ±0.19） mm. In the first week, there was no significant difference between three groups, in the second, third week, alveolar bone absorption values in the P1 group was significantly lower than the N group and the P2 group （P〈0.05）, but no difference between the N group and the P2 group. Conclusion： EA at Zusanli could improve the level of alveolar bone absorption.
