POST EXFOLIATION EXAMINATION The patients will be encouraged to bring the teeth to the dental clinic after exfoliation, and they will be promised a financial reward (10.00 ₪-ten Israeli shekels = US$.2.00 approximately). They will be instructed to keep the exfoliated tooth in tap water, and small plastic vials will be provided at the recall examination closest to shedding time. The proximal margins of the retrieved teeth will be evaluated for defects and discoloration using a dental explorer.
