Caries of First Permanent Molars and Association With Dietary and Oral Habits Among a Group of Egyptian Children

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.

Inclusion Criteria: * Age: 6 to 7 years old children * Children with written informed consent from their parents or guardians were included * Healthy child Exclusion Criteria: * Previous history/current radiotherapy and/or chemotherapy. * Presence of retained primary teeth or congenital or developmental anomalies affecting the permanent dentition. * Missing teeth due to causes other than dental caries. * Subjects undergoing orthodontic therapy, which might preclude normal tooth brushing. * Subjects who, in the opinion of the Investigator, may be non-compliant with study procedures.
