Abstract
Longitudinal microbiological examinations of dental plaque from children who developed nursing caries were carried out for 1 year. 9 children were included in the study, 5 of them developed caries lesions, while 4 remained caries-free. Two susceptible sites, the labial and palatal surfaces of the primary first incisor and a control site, the labial of the primary first mandibular incisor, were sampled. The plaque samples were analysed for the presence and numbers of members of Streptococcus, Actinomyces, Lactobacillus and Veillonella. The results showed significant differences between the levels of Streptococcus mutans, Lactobacillus and Veillonella at the sites which developed caries and the control sites in the same mouths. However, the susceptible sites which did not develop lesions in caries-active children supported a flora which was not significantly different from that of the lesion sites. This suggests that other factors beyond those which allow the establishment of a ‘pathogenic’ flora are involved in the development of a lesion. Veillonella were found in significantly higher amounts on the susceptible surfaces when compared to the controls. This finding was independent of the development of a lesion. It may be that the higher levels of Veillonella at susceptible sites reflect an increase in lactic acid in plaque. As some of these sites developed lesions, it does not seem likely that Veillonella were modifying the caries attack. There were no significant differences between the susceptible sites and control sites in the 4 children who did not develop caries. However, in 1 of these children, persistently high levels of S. mutans were present at susceptible sites.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
