Abstract:

Of the 85 originally caries free subjects, 40 remained caries free and 45 developed one or more carious lesions during a one year observation period. Within the group that remained caries free 30 per cent had lactobacilli counts at the end of this period, whereas, in the carious group 53.3 per cent had consistent numbers of lactobacilli in their saliva. The lactobacilli were evident approximately 5 months prior to the appearance of the initial lesions. The first and second molars were the teeth most frequently involved in the initial lesion. The largest percentage of pit and fissure lesions occurred in the second molars, accounting for almost twice as many as found in the first molars. In the caries active group, those individuals with consistent numbers of lactobacilli in their saliva primarily had pit and fissure cariess, whereas, the very low or negative lactobacilli group had proximal lesions.
