RESUMEN
OBJECTIVES: The aim of this study was to evaluate the effect of a motivation and practical skills development methods on the oral hygiene of orphans. MATERIAL AND METHODS: Sixty eight orphans aged between 7 and 17 years from two orphanages in Kaunas were divided into two groups: practical application group and motivation group. Children were clinically examined by determining their oral hygiene status using Silness-Löe plaque index. Questionnaire was used to estimate the oral hygiene knowledge and practices at baseline and after 3 months. Statistical analysis included: Chi-square test (χ(2)), Fisher's exact test, Student's t-test, nonparametric Mann-Whitney test, Spearman's rho correlation coefficient and Kappa coefficient. RESULTS: All children had a plaque on at least one tooth in both groups: motivation 1.14 (SD 0.51), practical application 1.08 (SD 0.4) (P = 0.58). Girls in both groups showed significantly better oral hygiene than boys (P < 0.001). After 3 months educational program oral hygiene status improved in both groups significantly 0.4 (SD 0.35) (P < 0.001). Significantly better oral hygiene was determined in practical application group 0.19 (SD 0.27) in comparison with motivation group 0.55 (SD 0.32) (P < 0.001). By comparing results of first and second questionnaire surveys on use of soft drinks, the statistically significant decline of their use was in both groups (P = 0.004). CONCLUSIONS: Educational programs are effective in improving oral hygiene, especially when they're based on practical skills training.
