Factors influencing the caries decline in Lithuanian adolescents--trends in the period 1993-2001.

The study aimed to relate a number of factors to the numbers of decayed, missing and filled teeth (DMFT) in 12- and 15-yr-olds examined and interviewed in 1993 and 2001. A total of 1250 children in 1993 and 935 in 2001 were clinically examined and completed a detailed questionnaire on dental health-related topics. Factors were related to the DMFT count applying multiple regression analysis. From 1993 to 2001, the mean DMFT decreased approximately 30% in both age cohorts. Despite an observed improvement in dental health in Lithuanian children, the number of Lithuanian children reporting frequent sugar consumption, brushing teeth irregularly and visiting the dentist only in case of emergency was still high compared with Western countries. The DMFT values were related to the fluoride content in the drinking water, oral hygiene, residency and year of examination.
