在 40 年的时间里，在一家私人诊所的 166 名患者中观察到了 455 颗被临床判断预后可疑的牙齿。 最初的治疗是清创并进行口腔卫生指导，然后进行皮瓣刮除术和预防性维护回忆治疗。还根据口腔卫生和召回出勤情况进行了依从性评估。共有 55 颗（12%）牙齿脱落，拔牙前平均存活率为 8.8 年。在头两年的观察期间，没有牙齿脱落。拔除的牙齿中，上颌第二磨牙最多（38.2%），其次是上颌第一磨牙（25.5%），下颌第二磨牙（16.4%）。牙齿缺失模式似乎是双侧对称的，51% 的牙齿缺失在右象限，49% 的牙齿缺失在左象限。拔牙的适应症主要是牙周脓肿。那些被认为预后非常可疑的牙齿在治疗、支持性治疗以及患者对回忆就诊的依从性之后已保留多年。
FOUR HUNDRED AND FIFTY-FIVE TEETH that were judged clinically to have a questionable prognosis were observed over a 40-year span in 166 patients in a private practice. Therapy initially was debridement with oral hygiene instruction, followed by flap curettage procedures and preventive maintenance recall therapy. An assessment of compliance based on oral hygiene and recall attendance was also performed. A total of 55 (12%) teeth were lost with an average survival rate of 8.8 years prior to extraction. No teeth were lost during the first 2 years of observation. The majority of extracted teeth were maxillary second molars (38.2%), followed by maxillary first molars (25.5%), and mandibular second molars (16.4%). Tooth loss patterns appeared to be bilaterally symmetrical, with 51% of teeth lost in the right quadrants and 49% lost in the left quadrants. Indications for extraction were primarily periodontal abscesses. Teeth that were considered to have a very questionable prognosis have been retained for many years after therapy, supportive treatment, and patient compliance with recall attendance.
