Prevalence of dental caries among children in a rural Tanzanian community.

The age specific prevalences of mixed caries were determined in 346 children aged 1 to 15 years in a rural community in Morogoro Region, south-eastern Tanzania. In primary dentition 58.9% of children were caries free while dmf index averages 1.08. In permanent dentition 74.3% were caries free while DMF index averaged 0.43. Permanent dentition showed a constant increase in caries prevalence with age such that over half of 15 year old children had caries experience with a DMF index of 1.2. This relatively low prevalence of caries is associated with low consumption of refined sugars. Recommendations are made to support preventive dental health services and programmes in primary schools and maternal and child health clinics.
