To evaluate yearly tooth loss rate (TLR) in periodontitis patients with different periodontal risk levels who had complied or not complied with supportive periodontal care (SPC).
Data from 168 periodontitis patients enrolled in a SPC program based on a 3-month suggested recall interval for at least 3.5 years were analyzed. For patients with a mean recall interval within 2-4 months ("compliers") or > 4 months ("non-compliers") with different PerioRisk levels (Trombelli et al. 2009), TLR (irrespective of the cause for tooth loss) was calculated. TLR values were considered in relation to meaningful TLR benchmarks from the literature for periodontitis patients either under SPC (0.15 teeth/year; positive benchmark) or irregularly complying with SPC (0.36 teeth/year; negative benchmark).
In both compliers and non-compliers, TLR was significantly below or similar to the positive benchmark in PerioRisk level 3 (0.08 and 0.03 teeth/year, respectively) and PerioRisk level 4 (0.12 and 0.18 teeth/year, respectively). Although marked and clinically relevant in non-compliers, the difference between TLR of compliers (0.32 teeth/year) and non-compliers (0.52 teeth/year) with PerioRisk level 5 and the negative benchmark was not significant.
A SPC protocol based on a 3- to 6-month recall interval may effectively limit long-term tooth loss in periodontitis patients with PerioRisk levels 3 and 4. A fully complied 3-month SPC protocol seems ineffective when applied to PerioRisk level 5 patients.
PerioRisk seems to represent a valid tool to inform the SPC recall interval as well as the intensity of active treatment prior to SPC enrollment.
评估不同牙周风险水平的牙周炎患者在遵守和不遵守支持性牙周治疗（SPC）的情况下，每年的牙齿缺失率（TLR）。
分析了一项基于 3 个月建议复诊间隔期的 SPC 计划中 168 名牙周炎患者的数据，该计划至少持续了 3.5 年。对于平均复诊间隔期在 2-4 个月（“遵守者”）或>4 个月（“不遵守者”）的患者，根据不同的 PerioRisk 水平（Trombelli 等人，2009 年），计算 TLR（与牙齿缺失原因无关）。考虑了 TLR 值与文献中 SPC 下的牙周炎患者（0.15 颗/年；阳性基准）或不规则遵守 SPC 的牙周炎患者（0.36 颗/年；阴性基准）有意义的 TLR 基准之间的关系。
在遵守者和不遵守者中，PerioRisk 水平 3（分别为 0.08 和 0.03 颗/年）和 PerioRisk 水平 4（分别为 0.12 和 0.18 颗/年）的 TLR 明显低于或与阳性基准相似。尽管在不遵守者中差异显著且具有临床意义，但 PerioRisk 水平 5 的遵守者（0.32 颗/年）和不遵守者（0.52 颗/年）之间的 TLR 与阴性基准之间的差异无统计学意义。
基于 3-6 个月复诊间隔期的 SPC 方案可能有效限制 PerioRisk 水平 3 和 4 的牙周炎患者的长期牙齿缺失。完全遵守 3 个月的 SPC 方案似乎对 PerioRisk 水平 5 的患者无效。
PerioRisk 似乎是一种有效的工具，可以告知 SPC 复诊间隔期以及 SPC 登记前主动治疗的强度。
