[Early childhood caries--a public oral health problem]

The purpose of this study was to determine the prevalence and severity of dental caries in preschool children from nurseries and kindergartens in Iaşi, an urban city in Romania.

The study assessed the dental health status in 2 age groups. The first group included 366 children aged 2, 5-3 years and the second group included 455 children aged 4,5-5 years in 2005. The children were subjected to dental examination in 2005 and 2006 and the prevalence and severity of caries for each age group were determined. Evaluation was based on questionnaire completed by mothers and on clinical assessment of preschool children's oral health status.

The mean number of decayed, missing and filled primary teeth (dmft) in the first group was 1.76 in 2005 and 2.39 in 2006, while the significant caries index increased from 4.79 to 6.35 during this period of time. For the 4.5-5 year children, the mean values for the dmft index were 3.95 in 2005 and 3.67 in 2006, while significant caries index increased from 7.89 to 8.4. Early childhood caries are the result of both inadequate diet behavior and cariogenic germs transmission from mother. The presence and extension of carious lesions in primary teeth are the most important predictors of permanent teeth disease. The high prevalence and severity of dental caries in pre-school children indicated that dental health program that include both prevention and treatment services targeted for young children and their parents is urgently needed.

Socio-economic status improvement, changes in lifestyle, effective use of oral health services, and most of all, oral hygiene and use of fluoride would lead to obvious changes in caries prevalence and severity of disease. The study high-lights the importance of change of attitudes and improvement of knowledge in parents, children and educators in order to reach a healthy lifestyle.
