This study examined the reasons for tooth loss in an adult population with dental insurance.
Computerized records were used to identify Kaiser Permanente Dental Care patients aged 40-69 years who had an extraction during 1992 (n = 1,877). A random sample of 839 dental charts were reviewed.
Slightly more than 51 percent of the teeth were extracted for periodontal disease, 35.4 percent for caries, 9.5 percent for a combination of the two, and 3.5 percent for other reasons. When considering patients as the unit of analysis, 58.4 percent of the patients had an extraction for caries, 39.9 percent for periodontal disease, 5.0 percent for both, and 2.6 percent for other reasons.
In this population both caries and periodontal disease play a role in tooth loss. For this reason, prevention programs focusing on the prevention of both disease processes should be developed for adults.
本研究调查了参加牙科保险的成年人群牙齿缺失的原因。
利用计算机记录识别出1992年期间接受拔牙治疗的40 - 69岁的凯撒医疗集团牙科保健患者（n = 1,877）。对839份牙科病历进行了随机抽样审查。
略多于51%的牙齿因牙周疾病而拔除，35.4%因龋齿拔除，9.5%因两者共同作用拔除，3.5%因其他原因拔除。以患者作为分析单位时，58.4%的患者因龋齿拔牙，39.9%因牙周疾病拔牙，5.0%因两者皆有拔牙，2.6%因其他原因拔牙。
在这一人群中，龋齿和牙周疾病均与牙齿缺失有关。因此，应为成年人制定侧重于预防这两种疾病进程的预防计划。
