Caries prevalence among schoolchildren in urban and rural Croatia.

Objective: The aim of the study was to evaluate caries prevalence in a sample of schoolchildren aged 6 to 16 years from rural and urban areas in Croatia.

Methods: Using standardized World Health Organisation (WHO) criteria, the oral health status of 1,589 children (265 from rural and 1,324 from urban areas) was assessed by recording the following indices: DMFT (decayed, missing, filled permanent teeth), deft (decayed, extracted, filled primary teeth), DMFS (decayed, missing, filled surfaces - permanent teeth), defs (decayed, extracted, filled surfaces - primary teeth) and SiC (Significant Caries Index). Rural areas were Štitar and Babina Greda municipalities in Slavonia and urban areas were the cities of Županja (Slavonia), Zagreb and Dubrovnik.
