Objective: To analyze the association between crowding, gingival status, oral hygiene, caries, salivary flow rate, S. mutans and lactobacilli counts, in two groups of children with mixed dentition, based on the assumption that with increasing age, increase the risk factors associated with caries and gingival status. Material and methods: The following were recorded for 131 schoolchildren (49.6% boys and 50.4% girls) between the ages of 8 (47%) and 10 (53%) years-old: crowding index, gingival index, IHOS index and dental caries index; as were risk indicators: stimulated salivary flow, and S. mutans and lactobacilli counts in biofilm and saliva. To establish differences between the groups, we ran a χ2 test and Student’s t test, before calculating the correlation coefficients. Results: No significant gender-based differences were found for any of the variables. We found differences between the groups with respect to lactobacilli counts in biofilm, OHIS, and stimulated salivary flow rate. Oral hygiene was the variable that registered the greatest number of significant correlations affecting negatively the oral health of these children. Conclusions: A greater amount of biofilm was associated with a higher gingival inflammation index. Children with crowding had a higher accumulation of biofilm, and the presence of biofilm was greater, the greater the number of crowded teeth, and the more biofilm, the greater the number of lactobacilli. Oral hygiene is a sensitive clinical indicator to predict risk and one that is easy to observe; it was superior in younger children.

Key words: Oral hygiene, crowding, dmfs/DMFS, salivary flow rate, mutans and lactobacilli counts.
