Endodontics and Prosthodontics Flashcards
Tx of the pulp cavity
Endodontics
Which teeth do we do endodontics on?
Canines and carnassial teeth
What are the three types of endodontic procedures?
Pulp-capping, vital pulpotomy, root canal
What procedure treats loss of enamel but no exposure of the pulp>
Indirect pulp capping
What is the goal of a direct pulp cap?
Preserve pulp and stimulate dentinal bridge to form
What does a direct pulp cap terat the exposure with?
Ca hydroxide sealer/cement, MTA
What is the goal of a vital pulpotomy?
Maintain a viable tooth that will continue to mature
Why will the tooth become dehydrated and more brittle over time without pulp?
Pulp is necessary to maintain dentin
When do you want to attempt a vital pulpotomy?
Immature tooth w/wide pullp cavity and open apex
How old can an animal be to do a vital pulpotomy?
Up to 5yr
How long after pulp exposure will a vital pulpotomy hae the greatest success?
<48hr
What are the two pulp treatment materials and which is preferred?
MTA (preferred) and Ca-hydroxide
How do MTA and Ca-hydroxide work?
Stimulate odontoblasts to lay down a bridge of dentin to seal the pulp cavity
What teeth can you do a root canal on?
Mature tooth
Why would we prefer a root canal vs. extraction?
Maintains tooth function even though tooth is “dead”
Which teeth do we do root canals in?
Canines and carnassials
Which instrument removes entire pulp as a single unit?
Barbed broach
What products can soften and disinfect dentin?
EDTA-containing products
When would you perform a surgical root canal?
Obstructed canal, failed conventional techique
Indicated to restore tooth to normal function and appearance
Prosthodontics
Resin and filler particles + coupler that is chemically/light activated
Composite restoration material
Polyacrylic acid and glass mix that bonds directly to dentin and enamel and releases flouride
Glass lonomer
What can happen if the restoration material leaks around margins?
Caries formation or potentially endodontic disease
What two types of crowns are there, which is preferred and why?
Porcelain and metal (preferred - can leave more tooth stock)
