AND SOLUTIONS
◉ Fluoride varnish?
Answer: Release fluoride on enamel, root structure and the dentin
surfaces.
◉ Varnish?
Answer: Organic solvent, seals dentin tubules and reduces
microleakage.
◉ Micro- mechanical?
Answer: Retention between the tooth structure and the restoration.
◉ Three things dental bases can do for the tooth?
Answer: 1. protective base
2. insulating base
3. sedative base
◉ Calcium Hydroxide?
Answer: Used as a base/ liner, promotes secondary dentin.
,◉ Smear layer?
Answer: Very thin layer of debris on newly prepared dentin.
◉ Crown matrix former?
Answer: Plastic form that is shaped as a crown. You put prepared
cement in the crown former.
◉ Provisional?
Answer: temporary cement until the permant restoration is ready to
be cemented.
◉ Permant Polycarboxylate?
Answer: Cement stainless steel crowns, and ortho bands.
