Oral health related quality of life in a group of Egyptian preschool children with early childhood caries: a cross-sectional study

Lower OHRQoL was significantly associated with the high prevalence of ECC and severe ECC (S-ECC), especially in domains related to pain, eating difficulties, and psychological discomfort. Higher dmft scores, the presence of ECC, younger parental age, and employment were also associated with worse OHRQoL scores. These results emphasize the importance of early preventive dental care, particularly for preschool children in resource-limited settings.
