The results of the 1980 survey showed that a majority of white American family members adhered to a strict toothbrushing schedule. The popular times of brushing were before bedtime, after breakfast, and on arising. This pattern of preferred brushing times was similar to that in the 1966 and 1974 surveys. Only a small percentage of the sample flossed daily. More than half of the sample visited their dentists regularly. More than 70% visited their dentists for preventive examinations or cleanings within the year before the survey was done. Compared with the results from the 1966 and 1974 surveys, the preventive dental behavior of the white American families has improved significantly since 1966.
1980年的调查结果显示，大多数美国家庭成员坚持严格的刷牙时间表。常见的刷牙时间是睡前、早餐后和起床后。这种偏好的刷牙时间模式与1966年和1974年的调查相似。只有一小部分样本每天使用牙线。超过一半的样本定期看牙医。超过70%的样本在调查前一年内因预防性检查或洗牙而去看牙医。与1966年和1974年的调查结果相比，自1966年以来，美国家庭的预防性牙齿保健行为有了显著改善。
