| dental cavity preparation | <dentistry> An operation in which carious material is removed from teeth and biomechanically correct forms are established in the teeth to receive and retain restorations. A constant requirement is provision for prevention of failure of the restoration through recurrence of decay or inadequate resistance to applied stresses. (boucher's clinical dental terminology, 4th ed, p239-40) (12 Dec 1998) |
| dental cement | <dentistry> Bonding substances available in the form of two components that are mixed together immediately before use, setting to a hard mass. They are used in restorative and orthodontic dental procedures as luting (cementing) agents, as bases, and as restorative materials.

| dental curing | <dentistry> The process by which plastic materials become rigid to form a denture base, filling, impression tray, or other appliance. (05 Mar 2000) |
| dental cuticle | The primary enamel cuticle, consisting of two extremely thin layers (the inner one clear and structureless, the outer one cellular), covering the entire crown of newly erupted teeth and subsequently abraded by mastication; it is evident microscopically as an amorphous material between the attachment epithelium and the tooth. Synonym: cuticula dentis, adamantine membrane, dental cuticle, membrana adamantina, Nasmyth's cuticle, Nasmyth's membrane, skin of teeth. (05 Mar 2000) |
| dental debonding | <dentistry> Techniques used for removal of bonded orthodontic appliances, restorations, or fixed dentures from teeth. (12 Dec 1998) |
