在积极的牙周治疗后，41名患者参加了为期2年半的维护计划，回忆间隔时间为2-6个月。在每次维护访视开始时，使用“探诊出血”（BOP）对牙周组织进行评估。仅在探查流血的的部位进行重新内固定。然而，龈上菌斑和牙石总是被去除。在积极治疗后和研究结束时记录囊袋探测深度和探测附着水平。牙周病的进展定义为观察到的探测附着丧失≥ 2 mm。BOP试验作为预测因子的可靠性通过计算敏感性、特异性、准确性以及阳性和阴性预测值进行评估。虽然频繁出血的敏感性仅为29%，但特异性为88%。疾病进展的阳性预测值仅为6%，阴性预测值为98%，这一事实使持续缺乏BOP成为维持牙周健康的可靠预测因素。
Following active periodontal therapy, 41 patients were incorporated in a maintenance program for 2 1/2 years with recall intervals varying between 2–6 months. At the beginning of each maintenance visit, the periodontal tissues were evaluated using “bleeding on probing” (BOP). Reinstrumentation was only performed at sites which bled on probing. However, supragingival plaque and calculus was always removed. Pocket probing depths and probing attachment levels were recorded after active treatment and at the conclusion of the study. Progression of periodontal disease was defined by an observed loss of probing attachment of ≥ 2 mm. The reliability of the BOP test as a predictor was evaluated by calculating sensitivity, specificity, accuracy, and positive and negative predictive values. While only a 29% sensitivity was calculated for frequent bleeding, the specificity was 88%. The fact that the positive predictive value for disease progression was only 6% and the negative predictive value was 98% renders continuous absence of BOP a reliable predictor for the maintenance of periodontal health.
