Parental Perception of Oral Health-Related Quality of Life in Sudanese Refugee vs. Egyptian Children

This cross-sectional analytical study aims to assess and compare parental perceptions of oral health-related quality of life (OHRQoL) among Sudanese refugee children and Egyptian children aged 6-12 years living in Egypt. The study will include 192 child-parent pairs (96 Sudanese refugees and 96 Egyptians). Data will be collected via a validated Arabic questionnaire adapted from the Child Oral Health Impact Profile (COHIP) and clinical oral health examinations using DMFT/dmft indices, Gingival Index, and Plaque Index. The study seeks to identify disparities in oral health, parental awareness, and access to dental care services, thereby informing future community-based interventions and public health policies targeting vulnerable populations such as refugee children.
