AIM
This registry-based retrospective cohort study aimed to evaluate the impact of furcation status on the risk for molar loss.
MATERIALS AND METHODS
Subjects with and without furcation involvement (FI) in 2010/2011 were identified in a nationwide registry in Sweden (age- and gender-matched sample: 381,450 subjects; 2,374,883 molars). Data on dental and periodontal status were extracted for the subsequent 10-year period. Impact of FI (at baseline or detected during follow-up) on molar loss (i.e., tooth extraction) was evaluated through multilevel logistic regression and survival analyses.
RESULTS
FI had a significant impact on molar loss. FI degrees 2 and 3 resulted in adjusted risk ratios of 1.67 (95% confidence interval [CI] 1.63-1.71) and 3.30 (95% CI 3.18-3.43), respectively. Following the first detection of deep FI (degrees 2-3), estimated survival decreased by 4% at 5 years and 8% at 10 years. In addition to FI, endodontic status and probing depth were relevant risk factors for molar loss.
CONCLUSIONS
Furcation status had a clinically relevant impact on the risk for molar loss. Following first detection of deep FI, however, the decline in molar survival was minor.
目的
本基于注册的回顾性队列研究旨在评估分叉状况对磨牙缺失风险的影响。
材料和方法
在瑞典的一个全国性注册中心，确定了 2010/2011 年存在和不存在分叉受累（FI）的受试者（年龄和性别匹配样本：381450 名受试者；2374883 个磨牙）。在随后的 10 年期间，提取了有关牙齿和牙周状况的数据。通过多水平逻辑回归和生存分析评估 FI（在基线时或随访期间发现）对磨牙缺失（即拔牙）的影响。
结果
FI 对磨牙缺失有显著影响。FI 程度 2 和 3 的调整后风险比分别为 1.67（95%置信区间[CI] 1.63-1.71）和 3.30（95%CI 3.18-3.43）。首次发现深度 FI（程度 2-3）后，5 年和 10 年的估计生存率分别下降了 4%和 8%。除了 FI 外，牙髓状况和探诊深度也是磨牙缺失的相关危险因素。
结论
分叉状况对磨牙缺失的风险有临床相关影响。然而，首次发现深度 FI 后，磨牙生存率的下降很小。
