COURSE CONTENT

Outcomes and Objectives:
At the conclusion of this course, the student should be able to:

Upon completion of this course, the student will be able to:

A.  Describe the characteristics of dental materials related to: classes

   of dental materials, structure, physical characteristics, mechanical

   characteristics, and biologic characteristics.

B.  Identify dental (restoration/prosthesis) examples of each type of

   class of material.

C.  Assess specific materials by comparing the actual characteristics to

   the ideal characteristics for materials to be used within the mouth

   to repair or replace oral tissues.

D.  Perform the steps necessary to place either a light-curing or self-

   curing sealant when presented with a client who has explorer-

   detectable deep pits and fissures.

E.  Identify the technique steps and associated rationales for amalgam

   finishing and polishing.

F.  Describe the clinical technique for the appropriate handling and

   manipulation of an alginate impression material (proportioning,

   mixing, placement and removal of tray from mouth, pouring and

   separation of the cast).

G.  Describe the type of cements useful for a special application as a

   periodontal dressing.

H.  Compare the composition and properties of the materials used as

   luting cements.

I.  Describe the procedure for placement and finishing of a temporary or

   interim restoration such as zinc oxide eugenol temporary restorative

   material.
