Caries preventive effect of wild tea (tsaang-gubat) among school children.

Urban Farm DB summary

A 3-year study in two elementary schools investigated the caries preventive effect of wild tea (tsaang-gubat) among schoolchildren. The experimental group drank one cup of tea daily for 17 months, prepared from fresh school garden leaves. Results indicated that wild tea is an effective caries preventive agent, showing a 75.67% decrease in caries incidence, though an increase in the third year was attributed to irregular consumption and reduced tea fluoride content.
