Smoothly flowing arcs and curves

Smoothly flowing arcs and curves

To help prevent stress concentration: The outline form should be composed of

Rounded

To help prevent stress concentration: All internal angles should be

Buccal and lingual extension

The cavity design should have greater

Approximately one third of the intercuspal dimension

Ideally, the width of the preparation at the isthmus should be

Primary teeth

Thinner Enamel & Dentin Layers

Enamel rods in cervical area are directed occlusally

Broad and flat contacts

Lighter color

Pulp horns high & pulp chambers large

Greater crown constriction & more prominent contour

Roots flared & more slender

Permanent teeth

Thick Enamel & Dentin Layer

Enamel rods in cervical area directed gingivally

Point contacts

Darker color

Smaller pulp chamber in relation to crown size

Less constriction in cervical area

Roots less flared and are bulbous

6 advantages of rubber dam use

1. Improve access and visualization

2. Superior moisture control

3. Safety of the child from aspiration of instruments & protection to the soft tissues

4. Decreased operating time

5. Aids behavior management

6. Child becomes a nasal breather enhancing nitrous oxide administration when deemed necessary from a behavioral standpoint.

Choice of appropriate clamp & Correct positioning

The fit of the rubber dam depends on this

Cavosurface margin

Varnish

Applied to teeth before use of zinc phosphate

Used with amalgam restorations

Varnish

Not placed under composite resins

Bases and Liners

Reduces marginal microleakage from the restoration

Bases and Liners

Prevents sensitivity

Zinc Oxide Eugenol (ZOE)

The material of choice for the pulp chamber filling material following pulpotomy and pulpectomy.

Zinc Oxide Eugenol (ZOE)

Not used as a base under resin-based composite resin because eugenol can inhibit the polymerization of the resin.

Stainless steel crown

Prefabricated crown forms that are adapted to individual teeth and cemented with a biocompatible luting agent.

Dr. William Humphrey in 1950

SSC was introduced to pediatric dentistry by who?

Extensive caries

Cervical decalcifications

Fractured primary teeth

3 indications of SSC

Esthetic concerns

Teeth are nearing exfoliation

Excessive tooth mobility

3 contraindications of SSC

Quality of tooth preparation

Selection and adjustment of appropriate crown

The luting cement

Success of SSC depends on:

169L Tapered Fissure Bur or 379 Football bur

Burs used for SSC crown preparation in occlusal reduction

169L or thin tapered diamond bur

Burs used for SSC crown preparation in proximal reduction

Size 4

Most commonly used SSC molar size

Crimping and contouring

It involves bending the gingival 1/3 of the crown’s margins inward to establish a tight marginal fit and adaptation

GI

Zinc phosphate

RMGIC

Luting cements that can be used in the cementation of SSCs

Lingual

What part of the crown should be seated first?

1mm

How far should crown margin extend into gingival sulcus?

Ledges

If there is resistance in seating of the crown without blanching of the gingiva, what should you check?

Tooth #65

In tooth preparation of tooth #64 , at which tooth should you place a clamp?

Pulpotomy

The surgical removal of the entire coronal pulp, leaving intact the vital radicular pulp within the canals

Dilution of formocresol used in pulpotomy

Calcium hydroxide

Agent most frequently used in direct pulp capping
