The occurrence of dental caries on adjacent approximal molar and premolar tooth surfaces was examined on posterior bitewing radiographs. More distal surfaces of the first permanent molars were decayed than adjacent mesial surfaces of the second molars. The appearance of dental caries on adjacent premolar surfaces was related to the order of eruption; the surface that had erupted first was likely to be decayed first. Reports from other studies on adjacent approximal surfaces indicate that this conclusion has a general bearing. It therefore seems important to increase the caries resistance of already erupted teeth by preventive means before and during the eruption of adjacent teeth.
在后部咬合翼片X线片上检查相邻磨牙和前磨牙邻面龋的发生情况。第一恒磨牙的远中面龋坏比第二磨牙相邻的近中面更多。相邻前磨牙表面龋的出现与萌出顺序有关；最先萌出的表面可能最先龋坏。其他关于相邻邻面的研究报告表明这一结论具有普遍意义。因此，在相邻牙齿萌出之前和期间通过预防手段提高已萌出牙齿的抗龋能力似乎很重要。
