The aim was to study the effect of flossing on proximal caries in children grouped according to different combinations of dietary and oral hygiene habits. 140 12--13-year-old children flossed the right or the left lateral region of the mouth once every school-day for 2 years by pulling a waxed floss once up and down through the proximal contacts. Proximal caries was recorded on bitewing films, taken at the baseline and at the 2-year registration. Diet history was obtained four times during the period. Oral hygiene was classified according to the number of bleeding points registered with a feather-loaded probe at the final examination. Caries increments on the control side during the experimental period were calculated for groups with the same habits. A logical border with respect to the amount of new caries was then established between suitable and unsuitable dietary habits as well as between sufficient and insufficient oral hygiene. No statistically significant difference was found between the control and experimental subgroups in the different combinations of dietary and oral hygiene habits, neither with respect to the whole material nor comparable contralateral surfaces. The numerical differences were so small that the technique of flossing studied here cannot be recommended.
目的是研究在根据饮食和口腔卫生习惯的不同组合分组的儿童中，使用牙线对邻面龋的影响。140名12至13岁的儿童在每个上学日对口腔右侧或左侧颊侧区域使用牙线一次，持续2年，通过将涂蜡牙线在邻面接触点上下拉动一次。在基线和2年记录时拍摄咬合翼片，记录邻面龋情况。在此期间获取四次饮食史。根据在最后检查时用带羽毛的探针记录的出血点数对口腔卫生进行分类。计算具有相同习惯的组在实验期间对照侧的龋增加量。然后在合适和不合适的饮食习惯以及充足和不充足的口腔卫生之间就新龋量建立一个合理界限。在饮食和口腔卫生习惯的不同组合中，无论是对于整个样本还是可比的对侧表面，对照亚组和实验亚组之间均未发现统计学上的显著差异。数值差异非常小，因此这里所研究的使用牙线技术不推荐使用。
