Introduction. Programs which lead to the teeth condition’s improvement and to the minimization of caries intensity should focus on children since their very first years of life. Aim. The aim of the study was to analyze the appearance of dental caries in 6 and 12 years old children from the Lubuskie Province during the National Monitoring of Oral Health program. Material and Methods. The survey material was obtained between 1999 and 2012 in the Lubuskie Province during carrying out both the National Monitoring of Oral Health program and „The Prevention of Dental Caries in children and adolescents in Gorzow Wielkopolski” Project (PL-0381). The prevalence and intensity of dental caries was presented for the group of 6 and 12 years old children. The restorative index was also calculated according to the formula: F/F+D. Results. The analysis showed that the value of caries intensity (DMFT) assessed during the implementation of the Project PL-0381 in children aged 6 was 0.1 whereas in 12-year‑old adolescents it was 2.69, while in the years of monitoring research the values were 2.1–4.7. Conclusions. The dentition of both children (6-year‑olds) and adolescent (12-year‑olds) in the Lubuskie Province is unsatisfactory. The data indicate needs for the prevention and treatment of dental caries in this province.

Key words: intensity of caries, children, adolescents.
