Caries experience in relation to oral hygiene, salivary cariogenic microflora, buffer capacity and secretion rate in 6-year olds and 12 year olds in Riga

Jekaterina Gudkina, Anda Brinkmane

Summary

The 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 and methods. 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 χ2 test 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.

Key words: caries experience, salivary cariogenic microflora, caries risk assessment.
