title: [Scanning electron microscopy of the normal and carious aprismatic enamel surface of human temporary teeth].
abstract: The study of human primary teeth surfaces by scanning electron microscopy has shown that the localization and the extent of the aprismatic surface layer although present in all teeth studied was quite variable from one tooth to an other. Such an aprismatic layer could be found along the molar fissures. However each tooth studied possessed an important surface layer consisting of prismatic enamel. The respective distribution of prismatic and aprismatic enamel layers was highly variable and can hardly by systematized. The study of apparently intact layers of incipient carious white spot lesions has shown that the irregular type of surface destruction was related to the presence of an aprismatic enamel surface layer.
