ABSTRACT
OBJECTIVE:
The aim was to assess possible relationship between oral hygiene, salivary cariogenic microflora, buffer capacity, secretion rate and caries experience in 6 year olds and 12 year olds in Riga, and to evaluate these variables in relation to caries risk. MATERIALS ANDMETHODS:
50 children aged 6 and 71 children aged 12 were examined clinically and by bitewing X-ray for caries diagnosis. Green-Vermillion oral hygiene index, stimulated salivary flow rate and buffer capacity were estimated (CRT-buffer; Ivoclar, Vivadent, Liechtenstein). Salivary mutans streptococci (MS) and lactobacilli (LB) (CRT-bacteria; Vivadent) were determined only for children with dmft/DMFT>4 60% at age of 6, 54,9% at age of 12. All data were statistically analyzed using frequency tables, Pearson chi2test and ANOVA analysis.RESULTS:
Mean DMFT was 0.12 in 6 year olds, and 4.6 in 12 year olds. Mean Green-Vermillion index was 0.75 in 6 year olds and 0.99 in 12 year olds. Caries experience and Green-Vermillion index were associated only in 6 year olds (p=0.024). Salivary MS was associated with Green-Vermillion index only in 12 year olds (p=0.086). Salivary MS and caries experience were associated only in 12 year olds (p=0.010). Salivary LB was associated with stimulated saliva's secretion rate only in 12 year olds (p=0.027). Salivary cariogenic microflora level and buffer capacity were associated in 6 year olds (p for MS=0.010; p for LB=0.052). Same association was observed only between salivary MS and buffer capacity in 12 year olds (p=0.081). Stimulated saliva's secretion rate and buffer capacity were associated only in 12 year olds (p=0.004).CONCLUSIONS:
Information of caries risk factors should be used to work effectively on caries reduction in 6 year olds and 12 year olds in Riga.
