These are the basic goals of and criteria for judging the various procedures.
The student will be able to:
- List and explain the rationale for the sequence of the "operative
principles:"
Operative Principles:
- Anesthesia
- Isolation
- Establish depth
- Outline form
- Ideal preparation completed
- . Excavation completed
- Demonstrate on a typodont tooth the ability to prepare a primary
molar to receive Class I and Class II amalgam restorations so that:
- the margins of the restoration will place in self-cleansing areas;
the proximal walls will parallel the external surface of the tooth;
- internal line angles are rounded to reduce incidence of mechanical
pulp exposure and reduce concentration of internal stresses in the
tooth
- the buccal and lingual cusps are not undermined;
- all areas of potential carious involvement on the occlusal surface
are included in the preparation;
- for the class II preparations the isthmus will be less than ½
but more than 1/3 of the distance between the buccal and lingual
cusp tips;
- the buccal axial line angle and the lingual axial line angle approach
90°;
- the pulpal axial line angle is beveled; and
- no level is created on the gingival margin.
- Demonstrate the ability to place a matrix band and to utilize appropriate
condensation technique so that:
- anatomy and contact are restored; and
- porosity is not evident in the restoration.
- Demonstrate the ability to carve an amalgam restoration so that:
- anatomy and proximal contact are restored;
- correct occlusion is restored; and
- marginal discrepancies are not created.
- Demonstrate on a typodont tooth the ability to prepare a primary
molar for a stainless steel crown restoration so that:
- the occlusal surface is reduced approximately 1mm providing ample
clearance for the thickness of the crown;
- the proximal reductions are parallel to the long axis of the
tooth (not tapered);
- creation of a gingival shoulder has been avoided; and
- all sharp line and point angles and cusps are rounded.
(Note: reduction of the gingival 2/3's of the buccal and lingual
surfaces is generally avoided).
- Demonstrate the ability to adapt a stainless steel crown to a prepared
primary molar so that:
- the cervical margin of the crown rests approximately 1mm below
the free margin of the gingival;
- the buccal and lingual surfaces are contoured to restore the appropriate
heights of contour;
- appropriate proximal contact is reestablished;
- there are no marginal discrepancies between the crown and the
tooth;
- the cervical margin is smoothly polished; and
- correct occlusion is restored.
- Demonstrate the ability to mix and place Dycal, I.R.M., Ketac-Cem
and Durelon following the manufacturer's directions.
- Demonstrate the ability to:
- prepare a tooth to receive a pit and fissure sealant;
- apply and polymerize sealant material according to the manufacturer's
directions, and
- evaluate the sealant for retention.
- Demonstrate the ability to fabricate a band and loop space maintainer
so that:
- the band is well-adapted to the tooth (no large voids between
band and tooth; band cannot easily be displaced);
- the loop follows the gingival contours;
- the loop is wide enough to allow partial eruption of the succedaneous
tooth; and
- the loop contacts the mesial abutment at the height of contour
of the distal surface.
- Demonstrate on a typodont tooth the ability to prepare a primary
and permanent molar to receive posterior resin restoration:
- excavate all the decay;
- no specific outline form required;
- apply a liner such as Dycal/Vitrebond if dentin is exposed
when all the decay is excavated;
- apply and polymerize the composite according to the manufacturer's
directions;
- apply and polymerize sealant material over the resin restoration,
according to the manufacturer's directions;
- evaluate the sealant for retention; and
- check the occlusion and adjust if necessary
