This cross-sectional study aims to assess the prevalence of dental caries in the first permanent molars of Egyptian children aged 6 to 7 years, and to examine how this caries status relates to the children's dietary habits and oral hygiene practices. A total of 272 children will undergo a clinical oral examination, and their parents or guardians will complete a structured questionnaire covering diet, tooth-brushing habits, and socio-demographic background. The findings are intended to help identify risk factors associated with early caries in these key teeth, supporting better-targeted preventive dental care for this age group.
