摘　　要：目的 探讨牙周基础治疗对慢性牙周炎(CP)牙周状况和最大咬合力的影响。方法 重度CP病例27例,每病例双侧磨牙各选择一患牙(初诊患牙牙周袋≥5mm,牙松动度≤Ⅱ度),随机分为龈上洁治组(S组)和根面平整组(P组)。S组患牙给予龈上洁治、碘氧液冲洗疗法;P组患牙予以龈上洁治、根面平整和碘氧液冲洗疗法。分别在治疗前和治疗后1、3、6个月测定息牙的咬合力值、龈炎指数(GI)、牙周袋深度(PD)。结果 ①P组治疗后1、3、6个月,最大咬合力值较治疗前有显著性提高(P<0.05);S组与治疗前无显著性差异(P>0.10)。②治疗后1个月,两组的咬合力值无显著性差异(P>0.05);治疗后3、6个月,P组的咬合力显著高于S组(P<0.01);③治疗后3、6个月,P组的GI值、PD值显著低于S组(P<0.001)。结论 洁治、根面平整治疗对于CP患牙的最大咬合力、GI、PD的改善是持续性的,较龈上洁治有显著性差异。Objective To evaluate the changes of the occlusal force and the gingival index (GI) and the pocket depth(PD) following non-surgical treatment in chronic periodontitis. Methods Two molar with similar periodontal status from two side of 27 chronic periodontitis patients were randomly divided into two groups. S group were treated with supragingival scaling: P group were treated with scaling ,and root planning. The data of the occlusal force, GI and PD was taken and evaluated at pretreatment and 1st 3rd, 6th month separately after treatment. Results There were significant differences between two groups in 3rd, 6th month after treatment. Root planning group get more improvement in GI, PD and occlusal force. Conclusion Compared with supragingival scaling, root planning is more effective in the increasing of the occlusal force and decreasing of PD and GI.
