The evidence for trends in caries experience among adults is examined by use of data from the NCHS NHANES I survey of dental disease, conducted from 1971 to 1974, and the NIDR Survey of Employed Adults and Seniors, conducted in 1985 and 1986. The main findings of the study are: (1) Mean DMF teeth and surfaces have declined among US employed adults who were 18-44 years old in 1985 compared with similar-aged persons in 1971-74; (2) differences in mean DMF teeth and surfaces could not be detected when persons aged 45 or older were compared; (3) missing and decayed components of DMF decreased in all age groups; (4) mean DF teeth decreased in persons under 30 years of age and mean DF surfaces in persons under 35; (5) improvements in DMF were demonstrated by both genders and all regions of the US; (6) all tooth types (anteriors, premolars, and 1st and 2nd molars) showed improvement in DMF; and (7) while employed whites clearly demonstrated an improvement in DMF, a commensurate improvement among employed blacks was not apparent. As measured by the DMF index, caries experience declined in US employed adults under 45 years old between 1971-74 and 1985.
利用1971年至1974年进行的国家卫生统计中心全国健康和营养检查调查（NCHS NHANES I）中的牙科疾病数据，以及1985年和1986年进行的国家牙科研究所（NIDR）就业成年人及老年人调查数据，对成年人龋齿患病情况的趋势证据进行了研究。该研究的主要发现如下：（1）与1971 - 1974年的同龄人相比，1985年年龄在18 - 44岁的美国就业成年人的平均恒牙龋失补牙数（DMF）和龋失补牙面数有所下降；（2）在比较45岁及以上人群时，未发现平均DMF牙齿和龋失补牙面数存在差异；（3）各年龄组的DMF中缺失和龋坏部分均有所减少；（4）30岁以下人群的平均龋补牙数（DF）牙齿和35岁以下人群的平均龋补牙面数有所下降；（5）美国所有性别和地区的DMF均有所改善；（6）所有牙型（前牙、前磨牙以及第一和第二磨牙）的DMF均有所改善；（7）虽然就业白人的DMF明显改善，但就业黑人中却未出现相应的改善。以DMF指数衡量，1971 - 1974年至1985年期间，美国45岁以下就业成年人的龋齿患病情况有所下降。
