The purpose of this study was to describe the prevalence of decayed, missing, and filled teeth among federal male prisoners (aged 21-75) in the US Penitentiary. Leavenworth, Kansas, and to assess the impact of age, race, number of years incarcerated, and number of visits to the prison dentist on these parameters of oral health. Inmates (n = 191) were randomly selected and represented 16.4 percent of the prison population (N = 1,161). Two calibrated examiners collected caries and tooth loss data using NIDR criteria. No radiographs were taken. Results showed a mean DMFT of 12.9 for inmates aged 20-34, 16.4 for inmates aged 35- 44, and 22.1 for inmates aged 45 and older. Whites had significantly fewer decayed teeth (P less than .05) than black inmates for ages 20-34. The number of missing teeth increased significantly (P less than .01) with inmate age. Proportion edentulous (both arches) was 5.2 percent for ages 35 to 44, 17.3 percent for ages 45-54, and 45.5 percent for ages 55 to 75. Cross tabulations and chi-square analyses showed that inmates incarcerated less than two years had a significantly (P less than .001) lower utilization rate of dental services, and that inmates who made greater use of available dental services had fewer decayed teeth than those with lower utilization rates.
本研究的目的是描述堪萨斯州莱文沃思美国监狱中21至75岁联邦男性囚犯的龋、失、补牙患病率，并评估年龄、种族、监禁年限以及就诊于监狱牙医的次数对这些口腔健康参数的影响。随机选取了191名囚犯，占监狱总人数（1161人）的16.4%。两名经过校准的检查人员使用美国国立牙科和颅面研究所（NIDR）的标准收集龋齿和牙齿缺失数据。未拍摄X光片。结果显示，20至34岁囚犯的平均龋失补牙指数（DMFT）为12.9，35至44岁囚犯为16.4，45岁及以上囚犯为22.1。在20至34岁年龄段，白人囚犯的龋齿数显著少于黑人囚犯（P值小于0.05）。随着囚犯年龄的增长，缺失牙数量显著增加（P值小于0.01）。35至44岁年龄段无牙（上下颌）比例为5.2%，45至54岁为17.3%，55至75岁为45.5%。交叉表和卡方分析表明，监禁时间少于两年的囚犯的牙科服务利用率显著较低（P值小于0.001），且较多使用现有牙科服务的囚犯的龋齿数少于利用率较低的囚犯。
