Evaluation of school-based prevention program in Turkey: Results of a 24-month study.

Objective: In this paper, cavity experiences of children with different levels of eruption and cavity activities that are enrolled at an elementary school with semi-rural characteristics in Kırıkkale Provincial center were monitored for 2 years after a variety of protective applications.

Materials And Methods: Three hundred and twenty-two children at the age of 7-11 were included in this study. Children were grouped as follows according to their cavity experiences and applications done: Group 1 - control group (with or without cavities) - was given hygiene training only; Group 2 - with medium level cavity activity (2-4 cavities in average) - oral hygiene training + surface restoration applied; Group 3 - children with 2-4 cavities on average - oral hygiene training + professional flour gel applied; Group 4 - children with 2-4 cavities in average - oral hygiene training + flour gel applied with brush; Group 5 - children with extreme cavity activity (children with 5 or more cavities) - oral hygiene training + surface restoration + professional flour gel combination applied.

Results: At the end of the 2(nd) year, 277 children were reached. The increase of number of cavities in permanent teeth was determined as 35%, 0%, 1%, 0%, and 7% in groups 1-5, respectively. The difference between groups was found to be significant (Chi-square analysis, Pearson Chi-square = 27.002, P < 0.01).
