We aimed to assess the association between furcation involvement (FI) and tooth loss for subjects not undergoing regular periodontal treatment.
Data from 2333 subjects participating in the baseline and 11-year follow-up of the Study of Health in Pomerania (SHIP) were used. All subjects had half-mouth periodontal examinations, including FI in one upper and one lower molar, at baseline. A total of 1897 subjects and 3267 molars were included in the final analysis.
In total, 375 subjects (19.8%) lost molars during the follow-up period. Respectively, 5.6%, 12.7%, 34.0% and 55.6% of molars without FI, degree I FI, degree II FI and degree III FI were lost. Initial probing pocket depth (PPD) and clinical attachment level (CAL) were associated with molar loss (p < .001). Baseline degree I FI was associated with a 1.73 IRR (incidence rate ratio) (95% CI=1.34-2.23, p < .001) of tooth loss while degree II-III was associated with a 3.88 IRR (95% CI=2.94-5.11, p < .001) of tooth loss compared to molars without FI at baseline.
This study provides evidence for an increased risk of molar loss affected by periodontal furcation involvement in a general population not undergoing regular periodontal care.
本研究旨在评估未经常规牙周治疗的受试者中，分叉受累（FI）与牙齿缺失之间的相关性。
本研究使用了参加波美拉尼亚健康研究（SHIP）基线和 11 年随访的 2333 名受试者的数据。所有受试者在基线时均接受了包括上下颌各一颗磨牙在内的半口牙周检查，包括 FI。最终分析共纳入 1897 名受试者和 3267 颗磨牙。
在随访期间，共有 375 名受试者（19.8%）失去了磨牙。分别有 5.6%、12.7%、34.0%和 55.6%的无 FI、FI Ⅰ度、FI Ⅱ度和 FI Ⅲ度磨牙发生了缺失。初始探诊袋深度（PPD）和临床附着丧失（CAL）与磨牙缺失相关（p<0.001）。基线时 FI Ⅰ度与磨牙缺失的 1.73 倍风险比（IRR）（95%CI=1.34-2.23，p<0.001）相关，而 FI Ⅱ-Ⅲ度与磨牙缺失的 3.88 倍 IRR（95%CI=2.94-5.11，p<0.001）相关，与基线时无 FI 的磨牙相比。
本研究为一般人群中未经常规牙周治疗的牙周分叉受累对磨牙缺失风险增加提供了证据。
