Changing patterns in the association between regional socio-economic context and dental caries experience according to gender and age: a multilevel study in Korean adults.

Background: Little is known about the effects of socio-environmental factors on dental caries in different demographic situations in Asian populations. We investigated whether the nature of the association between regional socio-economic context and dental caries experience differed according to gender and age groups in Korean adults.

Methods: We obtained a linked data set containing individual information from the 2000 Korean National Oral Health Survey and regional information from the "Major statistical indices of Si-Gun-Gu" (city-county-ward), published by the Korean Statistical Office.
