Common uses include temporary restoration of teeth, cavity linings to provide pulpal protection, sedation or insulation and cementing fixed prosthodontic appliances. Traditional cements are presented as separate powder and liquid components, manually mixed to form a viscous liquid, which then sets to form a brittle solid after application on the required treatment surface. More advanced cements, such as GIC, can also be presented in capsule form and are mechanically mixed using rotational or oscillating mixing machines.
