Oral health is a vital component of overall well-being, particularly during early childhood development. The early years, specifically between the ages of 3 to 6, mark a crucial period for establishing oral hygiene habits and preventing dental issues that can persist into adulthood. In this context, caregivers play a pivotal role as primary influencers in shaping children's oral health behaviors and practices. The aim of this study is the effect of critical role of caregiver education in promoting oral health status among 3 to 6-year-old children. A total of 400 caregivers with 3-6 years old children were randomly assigned into two groups: Group 1 (verbal + pamphlets) and Group 2 (verbal+ pamphlets + visual). Clinical examination was carried out to record oral health status (OHIS-M) in children. REALD-30 and CRA-RT were given to caregivers to assess oral health literacy and knowledge about their children before and after intervention respectively. Data were analysed using SPSS version 21. Descriptive analysis and paired t - test were used to test intervention impact. Among 376 caregivers/children, mean age of children were 5.28 years. After the intervention, Group 2 shows more significant difference between REALD-30 and OHIS-M when compared to Group 1 (p < 0.05). Verbal, Pamphlets and Visual aids (Group 2) were more effective in improving oral health status in children as compared to other group.
