AbstractObjectiveThis study aims to evaluate the 6‐month effects of an applied oral hygiene education program delivered through home visits for children with special needs in Istanbul. Additionally, the study seeks to establish an individualized oral health monitoring program and promote non‐cariogenic dietary habits.Methods and ResultsThe study included 279 children with special needs aged 1–8 years. Participants’ oral hygiene practices, dietary habits, and dental health status were compared before and after the education program. Plaque levels were assessed using the Silness‐Löe Plaque Index, and Streptococcus mutans (S. mutans) levels were measured using the Saliva‐Check Mutans test kit. After the intervention, the proportion of children brushing twice daily increased from 13.8% to 33% (p < 0.05), while the percentage of children with moderate plaque levels decreased from 40.1% to 26.5%. Additionally, the proportion of children with S. mutans levels exceeding 10⁵ CFU/mL decreased significantly from 91.3% to 68.0% (p < 0.005).ConclusionIndividualized oral hygiene education was found to be effective in improving oral health in children with special needs. Significant reductions in plaque levels and S. mutans concentrations were observed, along with increased parental awareness. Future multidimensional educational programs incorporating home visits may play a crucial role in maintaining long‐term oral hygiene habits in children with special needs.
