作者在236名9～32岁男女和255个离体牙上观察了早期龋损害的部位及其与菌斑的关系。表明恒磨牙咬合面中央点隙和远中点隙以及邻面的触点龈方是最敏感的部位。这些早期损害均与菌斑有显著的依存关系。这种关系在女性表现尤为突出。另外检查277颗离体牙邻面早期损害与触点关系时,发现在触点龈方受累者占84.48％,这也间接证明了龋病发生在菌斑堆积部分的显著性。对99颗磨牙的120个点隙沟的镜下观察,说明点隙沟的早期龋损害主要发生在底部。
The authors examined the location of early carious lesions on 236 men and women aged 9 to 32 and 255 isolated teeth and their relationship to plaque. Show that the permanent molar occlusal surface central gap and distal gap and the adjacent surface of the gingival contact is the most sensitive sites. These early lesions have a significant dependence on plaque. This relationship is particularly prominent in women. In addition, when examining the relationship between the early damage and the contact of 277 ex-dental necks, it was found that 84.48% of the affected gingival implants at the contact points indirectly demonstrated the significance of the dental caries in the plaque accumulation part. The microscopic observation of 120 point gap grooves of 99 molars showed that the early carious lesions of the point gap groove occurred mainly at the bottom.
