Summary
Objective
To evaluate educational strategies and ART-restoration impact on salivary physicochemical and microbiological characteristics.
Design
Two groups of 6-7-yr-old children were included: GART, with at least one decayed primary molar (n=36), submitted to 4 sessions of oral health educational strategy (OHES) and ART-restoration; GC, a paired caries-free group (n=36), submitted to 4 sessions of OHES. Three evaluations were carried out: baseline, one week after OHES and one month after OHES or ART, when biofilm and gingivitis frequencies, salivary flow, pH, buffer capacity, calcium and phosphorus concentrations were assessed. Total bacteria and S. mutans were quantified in unstimulated saliva (qPCR).
Results
Improvement in biofilm and gingivitis scores, salivary pH and buffering capacity after OHES was observed in GC, with a decrease in total bacteria and S. mutans counts. GART also showed changes in salivary parameters, even before ART-restoration was delivered, and total bacteria count remained lower than baseline one month after ART-restoration, although a trend to increase the proportion of S. mutans was observed.
Conclusion
Improvements in salivary physicochemical and microbiological characteristics were observed after educational strategies, thus reducing the caries-risk of children with decayed teeth, although a trend to increase the S. mutans percentage was observed one month after ART-restoration.
