背景/目的：在这项回顾性研究中，评估了牙周治疗和维护在预防牙齿脱落方面的功效。方法：该研究纳入了 92 名患有慢性成人牙周炎的患者，共有 2310 颗牙齿，观察时间平均为 6.7 年，每位患者在两个或多个象限内接受手术治疗。该小组分为两个小组：遵守建议的维护计划的小组和遵守情况不稳定的小组。根据放射学参数分配个体牙齿的预后。结果：在积极的牙周治疗完成时，有 2184 颗牙齿存在。维修期间，因牙周原因脱落44颗牙齿。牙齿死亡率显示，调整后的平均年牙齿脱落率为 0.07 颗/年。臼齿是最常脱落的牙齿。犬齿最少。三个预后类别中丢失的牙齿数量为：1 颗（0.07%）颗牙齿为预后良好，21 颗（3.63%）颗为预后可疑，22 颗（11.34%）颗为预后无望。不定期接受支持性牙周治疗的患者在积极治疗后牙齿脱落的风险比定期配合的患者高 5.6 倍。结论：结果表明，积极治疗结合严格的维护计划后，牙周患者的牙齿死亡率较低。
Background/Aims: In this retrospective study, the efficacy of periodontal therapy and maintenance in preventing tooth loss was evaluated.Methods: The study included 92 patients with 2310 teeth diagnosed with chronic adult periodontitis and observed over a mean period of 6.7 years, with each patient receiving surgical therapy in two or more quadrants. The group was divided into two subgroups: those who complied with the recommended maintenance schedule and those whose compliance was erratic. Individual tooth prognosis was assigned according to radiographic parameters.Results: At the completion of active periodontal therapy, 2184 teeth were present. During the maintenance period, 44 teeth were lost due to periodontal reasons. Tooth mortality revealed a mean annual adjusted tooth loss rate of 0.07/year. Molars were the teeth most frequently lost; canines the least. The number of teeth lost in the three prognostic categories was: one (0.07%) for teeth with good prognoses, 21 (3.63%) for questionable prognoses and 22 (11.34%) for hopeless prognoses. Patients complying erratically with supportive periodontal therapy were at a 5.6 times greater risk for tooth loss following active therapy than regularly compliant patients.Conclusions: The results demonstrated a low tooth mortality rate in periodontal patients following active treatment combined with a strict maintenance program.
