This retrospective study focused on the frequency of tooth loss due to periodontal abscess among 42 patients who were treated by a single clinician over a 5- to 29-year period. A total of 114 patients were selected from the active periodontal recall schedule of a single periodontist at The University of Iowa College of Dentistry. The criteria for inclusion in the study included having a history of moderate to advanced periodontitis, being on 3 to 6 month recall periodontal maintenance care, and completion of active periodontal therapy prior to October 1987. Other parameters evaluated were age; gender; number of teeth present and missing at the initial, reevaluation, and last periodontal recall visit; initial periodontal prognosis; furcation involvement; non-surgical and surgical periodontal therapy; and reasons for tooth loss. Patients were grouped according to the number of teeth lost following active periodontal treatment into well-maintained (0 to 3), downhill (4 to 9), and extreme downhill (10 to 23) groups. Forty-two of the 114 patients were identified as having one or more periodontal abscesses. A total of 109 teeth were affected by periodontal abscess of which 49 (45%) teeth were lost and 60 (55%) were successfully maintained over an average of 12.5 years (5 to 29 years). More furcated teeth were lost than nonfurcated teeth and teeth given a hopeless prognosis were lost more consistently than those given a questionable prognosis in all groups. The frequency of periodontal abscess and tooth loss per patient was greater in the downhill and extreme downhill response groups than the well-maintained group. This suggests that teeth with a history of periodontal abscess can be treated and maintained for several years.
这项回顾性研究聚焦于在5至29年期间由一名临床医生治疗的42例患者中因牙周脓肿导致牙齿缺失的频率。总共114例患者选自爱荷华大学牙科学院一名牙周病医生的活跃牙周复查计划。纳入该研究的标准包括有中度至重度牙周炎病史、处于3至6个月的牙周维护护理复查期以及在1987年10月之前完成活跃牙周治疗。评估的其他参数包括年龄、性别、在初次、重新评估和最后一次牙周复查就诊时现存和缺失的牙齿数量、初始牙周预后、根分叉病变、非手术和手术牙周治疗以及牙齿缺失原因。患者根据活跃牙周治疗后牙齿缺失数量被分为维护良好组（0至3颗）、病情恶化组（4至9颗）和极度恶化组（10至23颗）。114例患者中有42例被确定有一处或多处牙周脓肿。共有109颗牙齿受到牙周脓肿影响，其中49颗（45%）牙齿缺失，60颗（55%）牙齿在平均12.5年（5至29年）期间成功保留。根分叉病变的牙齿比无此病变的牙齿缺失更多，且在所有组中，预后无望的牙齿比预后可疑的牙齿更易缺失。病情恶化组和极度恶化组中每位患者的牙周脓肿和牙齿缺失频率高于维护良好组。这表明有牙周脓肿病史的牙齿可以治疗并保留数年。
