Radiation Caries

This study aims to evaluate and compare the remineralizing and antimicrobial effects of nano silver fluoride and bioactive glass gel on primary teeth exposed to therapeutic radiation. The study includes both in vitro and in vivo components. The clinical component will include 30 pediatric patients aged 6-10 years undergoing therapeutic head and neck radiotherapy. Participants will be randomly allocated into two groups to receive either nano silver fluoride or bioactive glass gel. The effects of the interventions will be evaluated using salivary pH and bacterial count measurements. The laboratory component will evaluate changes in irradiated primary tooth enamel, including surface morphology, mineral content, and microhardness.
