Phencyclidine (PCP) was originally developed as an anesthetic, but the adverse side effects prevented its use except as a large animal tranquilizer. PCP acts as both a depress â¦ ant and a hallucinogen,and sometimes as a stimulant. It is abused primarily for its variety of mood-altering effects.
1 An inlay- As the name suggests, this restoration sits inside the tooth.  An onlay- In contrast is bonded on top of the tooth, replacing some or all of the cusps of the tooth.
Inlays and onlays are sometimes called indirect fillings, and the reason for this is that they would normally require more than one visit to the Cosmetic Dentistry Center. This will still be the case if you opt for gold inlays or onlays, as they have to be made on-site in our dental laboratory. Your tooth will be prepared before an impression is taken and sent to our laboratory for your gold inlay or onlay to be custom-made.
