Midterms Flashcards
Is the likelihood of the patient having new caries lesions in the near future
Caries risk
Cavitated ot non-cavitated dental lesions caused by dental caries process
Caries lesion
Are environmental factors, biological or chemical therapy that help to swim the caries balance to caries lesion prevention or reversal
Protective factors
Are environmental or biological factors that contribute to the initiation or progression of carious lesion
Risk factors
Are clinically observed results of previous and/or ongoing dental caries destruction of the tooth mineral
Disease indicators
A scientific, evidence-based solutions for prevention and treatment of caries before they have reached the cavitated stage
Caries management by risk assessment
Dental cares is a ___ medical condition, not a mechanical problem
Manageable
Caries Classification according to anatomical site
Pits and fissure caries
Smooth surface caries
Root caries
Classification according to new lesion or recurrent lesion
Primary caries
Recurrent caries
Residual
Lesion on unrestored surface
Primary caries
Aka “secondary caries”
Lesion developing adjacent to restoration
Recurrent caries
Caries that remains in the prepared tooth surface even after placing restorations
Residual carries
Pathway of caries spread
Forward and backward caries
Caries cone in enamel is larger or equal to that in the dentin
Forward carioes
Spread of caries along the DEJ exceeds that in the contagious enamel
Backward caries
Classification based on number of tooth surface involved
Simple caries
Compound caries
Complex caries
One tooth surface is involved: buccal, mesial
Simple caries
Connected surface involved:mesiobuccal or distobuccal
Compound caries
three surface involved: connected or separated
Complex caries
Time of progression of caries
18 (+/- 6months) on smooth surface caries
Peak progession of caries
3 years
Progression is __ in healthy individuals
Slower
First clinical evidence of demineralization
White spots
Reason why white spots occur
Poor oral hygiene
Enamel caries follow the direction of???
Enamel prism or rods
White spots can only be seen if the oral cavity is
Dessicated
Initial lesion of smooth surface caries
On proximal surfaces
Smooth suface caries can be reminaralized by
Salivary fluoride
In pits and fissure caries,initial caries starts at the?
Lateral walls of fissre
Zones of enamel caries
Translucent zone
Dark zone
Body of lesion
Surface zone
Zone of enamel caries which is the deepest zone layer: near dentin
Translucent zone
Zone of enamel caries that represent the advancing front of the lesion
Translucent zone
Zone of enamel caries that is referred to as positive zone
Dark zone
Zone of enamel caries that does not transmit polarized light
Dark zone
Larges portion of zone of enamel caries
Body of lesion
Zone of enamel caries that is the area of greatest demineralization
Body of lesion
One of enamel caries that is not or least affected by caries
Surface zone
Why is the surface zone of enamel caries has a greater resistance
Because they are accessible by the sailva which helps with the mineralization
Zones f dentinal caries
Zone of fatty degeneration
Zone of dentinal sclerosis
Zone of decalcification of dentin
Zone of bacterial invasion
Zone of decomposed dentin
Types of explorer
Interproximal
Straight
Shepherd’s hook
