Estimating prognosis of periodontally affected teeth at the beginning of supportive periodontal care (SPC) is an important component for further treatment planning. This study aimed to evaluate tooth loss (TL) during 10 years of SPC in periodontally compromised patients and to identify tooth-related factors affecting TL.
Patients were re-examined 120 ± 12 months after accomplishment of active periodontal therapy. TL was defined as primary outcome variable and tooth-related factors (abutment status, furcation involvement [FI], tooth mobility, mean periodontal probing depth [PD], and clinical attachment level [CAL] at beginning of SPC, and initial bone loss [BL]) were estimated based on an adjusted regression analyses model.
Ninety-seven patients (51 females and 46 males; mean age, 65.3 ± 11 years) lost 119 of 2,323 teeth (overall TL [OTL]: 0.12 teeth/patient/y) during 10 years of SPC. Forty of these teeth (33.6%) were lost for periodontal reasons (TLP; 0.04 teeth/patient/y). Significantly more teeth were lost due to other reasons (P <0.0001). TLP (OTL) only occurred in 5.9% (14.7%) of all teeth, when BL was at least 80%. Use as abutment tooth, FI degree III, tooth mobility degrees I and II, mean PD, and CAL positively correlated with OTL (P <0.05). For TLP, FI and tooth mobility degree III as well as mean CAL were identified as tooth-related prognostic factors (P <0.05).
During 10 years of SPC, most of the teeth (93.4%) of periodontally compromised patients were retained, showing the positive effect of a well-established treatment concept. Well-known tooth-related prognostic factors were confirmed.
在牙周支持治疗（SPC）开始时估计受牙周影响的牙齿的预后是进一步治疗计划的重要组成部分。本研究旨在评估牙周病患者在 SPC 期间 10 年内的牙齿缺失（TL），并确定与牙齿相关的因素影响 TL。
在完成积极牙周治疗后 120±12 个月对患者进行重新检查。TL 定义为主要结局变量，根据调整后的回归分析模型，对与牙齿相关的因素（基牙状况、分叉受累[FI]、牙齿松动度、SPC 开始时的平均牙周探诊深度[PD]和临床附着水平[CAL]以及初始骨丧失[BL]）进行评估。
97 名患者（51 名女性和 46 名男性；平均年龄 65.3±11 岁）在 SPC 的 10 年内失去了 2323 颗牙齿中的 119 颗（总 TL[OTL]：0.12 颗/患者/年）。其中 40 颗牙齿（33.6%）因牙周原因（TLP；0.04 颗/患者/年）丢失。其他原因导致的牙齿缺失明显更多（P<0.0001）。当 BL 至少为 80%时，仅 TLP（OTL）发生在所有牙齿的 5.9%（14.7%）中。基牙、FI 度 III、牙齿松动度 I 和 II、平均 PD 和 CAL 与 OTL 呈正相关（P<0.05）。对于 TLP，FI 和牙齿松动度 III 以及平均 CAL 被确定为与牙齿相关的预后因素（P<0.05）。
在 10 年的 SPC 期间，牙周病患者的大多数牙齿（93.4%）得以保留，表明了既定治疗理念的积极作用。证实了众所周知的与牙齿相关的预后因素。
