To evaluate the association between risk scores generated with a simplified method for periodontal risk assessment (Perio Risk), and tooth loss as well as bone loss during supportive periodontal therapy (SPT).
MATERIALS & METHODS: Data related to 109 patients (42 males; mean age: 42.2 ± 10.2 years, range 22-62) enrolled in a SPT programme for a mean period of 5.6 years were retrospectively obtained at two specialist periodontal clinics. Patients were stratified according to Perio Risk score (on a scale from 1 - low risk to 5 - high risk) as calculated at the end of active periodontal therapy. Risk groups were compared for tooth loss as well as the changes in radiographic bone levels occurred during SPT.
The mean number of teeth lost per patient during SPT varied from 0 to 1.8 ± 2.5 for patients with a risk score of 1 and 5 respectively (p = 0.041). Mean radiographic bone loss during SPT was ≤0.5 mm in all risk groups, without significant inter-group differences.
Periodontal risk assessment according to Perio Risk may help to identify patients at risk for tooth loss during SPT.
评估简化牙周病风险评估（Perio Risk）方法生成的风险评分与牙周支持治疗（SPT）期间牙齿缺失和骨丧失之间的关系。
回顾性获取了在两个牙周病专科诊所接受 SPT 计划治疗的 109 名患者（42 名男性；平均年龄：42.2 ± 10.2 岁，范围 22-62 岁）的数据。根据主动牙周治疗结束时计算的 Perio Risk 评分（从 1 分-低风险到 5 分-高风险）对患者进行分层。比较风险组之间在 SPT 期间发生的牙齿缺失以及影像学骨水平变化。
在 SPT 期间，每个患者丢失的平均牙齿数从风险评分 1 的患者的 0 到 1.8 ± 2.5 不等，而风险评分 5 的患者则为 0 到 1.8 ± 2.5（p = 0.041）。在所有风险组中，SPT 期间的平均影像学骨丢失均≤0.5mm，且组间无显著差异。
根据 Perio Risk 进行牙周病风险评估可能有助于识别 SPT 期间牙齿缺失风险较高的患者。
