在一项纵向研究中，对83名接受系统3个月维护护理的成人牙周炎患者进行了CPITN六分仪评分与牙周炎复发之间的关系的评估。在超过36个月的基线和半年度考试中。CPITN评分通过牙周探诊深度和牙龈指数评分分配给每个牙列六分仪，并使用咬合参考支架评估各个牙齿部位的相对骨膜附着水平。牙周炎复发定义为任何牙周部位，其≥探诊深度较基线增加3 mm，或S探诊深度较基线增加1 mm，并伴有≥相对牙周附着丧失。在36个月的研究期间，49例(59.0%)受试者发生牙周炎复发，147例(29.8%)发生牙周炎复发，181例(2.2%)个别牙周部位复发。疾病活动期受试者的基线CPITN评分为4比临床稳定受试者更常见(p=0.003)。/-检验)，并且与36个月内牙周炎复发的相对风险有统计学意义的1.66相关。CPITN六分仪评分为3分或4分时，在受影响的六分仪中S=1的个别部位，作为牙周炎复发的指标，其特异性和阳性预测值都很低。相比之下，CPITN六分仪评分低(0~2分)具有较高的特异性(96.2~100%)。高阳性预测值(99.5-100%)，综合优势比为24.2，作为给定牙列六分仪内所有牙周部位临床稳定性的指标。CPITN的六分仪评分在6个月期间的变化与个别牙周部位的牙周炎复发无关。这项研究表明，虽然CPITN不足以检测牙周炎复发，但CPITN评分较低可以为正在接受维护护理的成人牙周炎患者提供快速、临床稳定的六分体识别。
The relationship between CPITN sextant scores and periodontitis recurrence at individual tooth sites was evaluated in a longitudinal study in 83 treated adult periodontitis patients receiving systematic 3‐month maintenance care. At baseline and semi‐annual examinations over 36 months. CPITN scores were assigned to each dentition sextant using probing depths and gingival index scores, and relative periodomal attachment level was assessed at individual tooth sites using an occlusal reference stent. Periodontitis recurrence was defined as any periodontal site exhibiting either a probing depth increase of ≥3 mm from baseline, or a probing depth increase of s 1 mm from baseline together with a loss of relative periodontal attachment of ≥2 mm from baseline. 49 (59.0%) subjects developed periodontitis recurrence in 147 (29.8%) sextants at 181 (2.2%) individual periodontal sites during the 36‐month study period. Baseline CPITN scores of 4 were more common in disease‐active subjects than clinically‐stable subjects (p= 0.003. /‐test), and were associated with a statistically significant 1.66 relative risk of periodonlitis recurrence within 36 months. CPITN sextant scores of 3 or 4 showed low specificity and low positive predictive values as indicators of periodontitis recurrence at s= 1 individual sites within the affected sextant. In comparison, low CPITN sextant scores (0‐2) provided high specificity (96.2‐100%). high positive predictive values (99.5‐100%), and a summary odds ratio of 24.2 as an indicator of clinical stability at all periodontal sites within a given dentition sextant. Changes in sextant scores for CPITN over 6‐month periods showed no relationship with periodontitis recurrence at individual periodontal sites. This study suggests that while CPITN is inadequate for detection of periodontitis recurrence, low CPITN scores provide rapid presumptive identification of clinically‐stable sextants in adult periodontitis patients on maintenance care.
