The goal of this clinical trial is to to assess the remineralization potential of Egg shell hydrogel versus fluoride varnish in early carious white spot lesions in anterior primary teeth.
The main question it aims to answer is:What is the remineralization potential of egg shell hydrogel on early carious white spot lesions compared to fluoride varnish in anterior primary teeth? Researcher will compare egg shell hydrogel with fluoride varnish to see if it is able to promote lesion remineralization.
interventions that will be given to participasnts: egg shell hydrogel \& five percent sodium fluoride varnish
Children aged 3 to 5 years, in good general health, and medically free.
Prescence of at least one WSL on anterior primary teeth with an ICDAS II score of one or two.
Cooperative patients who will comply with follow-ups.
Parents who accept to sign informed consent.
Uncooperative children.
Children with a physical disability or medical disability.
Children with teeth that shows enamel hypoplasia.
Children that have received a fluoride supplement or professional topical fluoride application at least 3 months before the study.
