Summary

This observational study will compare dental caries (tooth decay) experiences and quality of life between visually impaired and sighted children aged 6 to 14. Researchers will use a special questionnaire to measure how cavities affect daily life, and will also count decayed, missing, and filled teeth. The goal is to understand if visual impairment leads to worse dental health outcomes.
