This retrospective study evaluates and assigns scores to six prognostic factors and derives a quantitative scoring index used to determine the periodontal prognosis on molar teeth.
Data were gathered on 816 molars in 102 patients with moderate-to-severe periodontitis. The six factors evaluated (age, probing depth, mobility, furcation involvement, smoking, and molar type) were assigned a numeric score based on statistical analysis. The sum of the scores for all factors was used to determine the prognosis score for each molar. Only patients with all first and second molars at the initial examination qualified for the study. All patients were evaluated a minimum of 15 years after treatment.
The post-treatment time ranged from 15 to 40 years and averaged 24 years. When the study was completed, 639 molars survived (78%), and, of those surviving molars, 588 survived and were periodontally healthy (92%). In molars with lower scores (scores 1-3), the 15-year survival rates ranged from 98% to 96%. In molars with middle scores (scores 4-6), the 15-year survival rates ranged from 95% to 90%, and, for molars with higher scores (scores 7-10), the survival rates ranged from 86% to 67%.
The present results indicate that the periodontal prognosis of molars diagnosed with moderate-to-severe periodontitis can be calculated using an evidence-based scoring index.
本回顾性研究评估并为六个预后因素评分，并得出一个定量评分指数，用于确定磨牙的牙周预后。
收集了 102 名中重度牙周炎患者的 816 颗磨牙的数据。根据统计分析，评估了 6 个因素（年龄、探诊深度、松动度、分叉受累、吸烟和磨牙类型），并根据这些因素的评分确定每个磨牙的预后评分。只有在初始检查时所有第一和第二磨牙都存在的患者才有资格参加研究。所有患者在治疗后至少 15 年进行评估。
治疗后时间范围为 15 至 40 年，平均为 24 年。当研究完成时，639 颗磨牙存活（78%），在存活的磨牙中，588 颗磨牙存活且牙周健康（92%）。在评分较低的磨牙（评分 1-3）中，15 年生存率从 98%到 96%不等。在评分中等的磨牙（评分 4-6）中，15 年生存率从 95%到 90%不等，而在评分较高的磨牙（评分 7-10）中，生存率从 86%到 67%不等。
目前的结果表明，中重度牙周炎诊断的磨牙的牙周预后可以使用基于证据的评分指数来计算。
