Operative Dentistry Flashcards
Hyper occlusion may lead to what?
Inflammation of the periodontal ligaments
What type of medication deals with inflammation
NSAIDs
What are some examples of NSAIDs
Ibuprofen and Motrin
What four factors contribute to caries?
- Host
- Time
- Fermented Carbohydrates
- Cariogenic Biofilm
Critical pH
5.5
De-mineralization
Teeth lose materials when mouth chemistry becomes acidic.
Re-mineralization
Teeth gain minerals when mouth chemistry is neutral or slightly alkaline.
Streptococcus mutans and Lactobacillus acidophilus
Both are acidogenic and aciduric
Fermentation sugars or carbohydrates to initiate acid.
Lactobacillus acidophilus
Has low affinity for tooth surface
Favor deep dentinal caries
Streptococcus mutans
Involved in initiation of caries
Ferments sucrose (lactic acid) produces high volumes of acid
Which bacteria is responsible for pit and fissure caries?
S. mutans
S. sanguis
Lactobacillus species
Actinomycetes species
Which bacteria is responsible for smooth surface caries
S. mutans
S. salivarius
Which bacteria is responsible for root surface caries?
A. viscous
A. naeslundi
S. mutans
S. sanguis
Which bacteria is responsible for deep dental caries?
Lactobacillus species
A. naeslundi
Class I
Pit and fissure caries
Class II caries
Caries of the proximal surface of posterior teeth.
Incipient
Refers to reversible caries. Caries limited to the enamel. Which can be remineralized.
Cavitated
Decay that has penetrated the DEJ
Change in color transluceny
Remineralization is not possible
Class III
Caries on proximal surface of anterior teeth
Class IV caries
Caries on proximal and Incisal surface of anterior teeth.
Class V carries
Caries on the gingival 1/3 of the lingual or facial surface of all teeth
