摘要
目的利用牙周探诊深度（probingdepth，PD）和附着丧失（attachment loss，AL）评估危险因素对慢性牙周炎预后的影响。方法选取2006年1月至2012年6月于中国医科大学附属口腔医院牙周科就诊并被诊断为慢性牙周炎的459例患者，应用危险因素评估软件对其危险因素情况进行评估分级，共分为5组（Riskl。Risk5组），危险因素的严重程度从Risk1组到Risk5组依次递增。对所有患者进行牙周检查和牙周基础治疗，检查的指标为所有天然牙的近中颊、颊正中、远中颊和舌正中4个位点的PD和AL。在治疗后3个月、第1年、第2年、第3年时复诊，检查牙周指标，与基线比较并评价牙周炎症进展情况。结果治疗后不同时间的牙周指标与基线相比得知，3个月时炎症明显改善（P〈0．05）。牙周炎症在危险因素的影响下逐渐恶化，并在治疗后第3年时这种影响比较明显（P〈0．05）。在治疗后第3年比较各组的PD和AL发现，Riskl和Risk2组与其他3组间差异有统计学意义（P〈0．05），Risk5组与其他4组间差异均有统计学意义（P〈0．05），并因此将危险因素的严重程度分为低、中、高3个风险等级。结论（1）本研究中危险因素评估软件能够准确、快速地对患者的各个危险因素情况进行分析，得出患者危险因素的风险等级，帮助医生做出正确的预后判断，并帮助患者更好的认清危险因素的影响。（2）危险因素在牙周炎症的发生发展中起着重要作用，能够有效预测牙周炎症的预后，其对牙周炎症的影响在治疗后第3年就表现出来，应引起医生和患者的重视。
Objective To evaluate the influence of risk factors on prognosis by using probing depth and attachment loss for chronic periodontitis. Methods A total of 459 patients were selected from January 2006 to June 2012. Two hundred and four cases were male and two hundred and fifty-five were female, among whom the age range was from 25 to 75 years and the mean age was 42.65 years. These patients were assessed and divided by self-development risk factors as- sessment software into five groups, in which the severity of risk factors from group one to five was in ascending deteriora- tion order. Three months later periodontal examination were taken after all patients accepted periodontal initial therapy, that is, detecting indication was pocket depth （PD） and attachment loss （AL） of mesial buecal, buceal, distal buceal and lingual of all teeth. The prognosis of periodontitis was evaluated by comparing the periodontal index of the first, second, and the third year to baseline. Results Comparing the periodontal index on the different times after initial therapy to baseline, periodontitis improved obviously on the third month（P 〈 0.05）. Under the influence of risk factors periodontitis was deteriorated gradually, apparently in the third year （P 〈 0.05）. Similarly comparing the PD and AL among five risk groups on the third year, there was a significant statistical difference （P 〈 0.05） between Risk1, Risk2 and other three groups. By the same way Risk5 got the significant statistical difference compared to other four groups, therefore we could divide the risk factor into three levels , which were low level, middle level, and high level. Conclusions （1） In this study, all risk factors are analyzed and the patients＇ risk level are obtained quickly and accurately by risk factors assessment software, which can help the doctor to make the right judgment of prognosis and help the patients to understand the influence of risk fac- tors. （2）Risk factors play an important role and can predict the progno
