Caries Flashcards
Caries require 3 factors:
Bacteria, carbohydrates, tooth
Caries progression can be three types:
Incipient, moderate, severe.
(enamel only, involving dentin, involving pulp)
What is the typical location of proximal caries?
a few mm apical from the contact point
How to diagnose caries?
Clinical exam is always necessary: occlusal caries are easy to diagnose clinically, Labial/ Buccal?palatal caries: easy to diagnose clinically
Proximal Caries:may be difficult to diagnose clinically.
True or False: Radiography cannot reveal if a lesion is active or arrested
True
True or False: Bitewing Radiographs are Best to assess for proximal and occlusal caries
True
True or False: PA is good for identifying occlusal caries.
True
True or False: PA is reliable for incipient caries
False
True or False: CBCT is reliable for incipient caries
False
What are the minimum factors required for the development of caries?
Tooth, Bacteria, Carbohydrates.
Incipient caries are:
Dark or radiolucent area on the surface. Enamel only. 50% of lesions are actually visible on radiographs (50% not seen)
Proximal caries are:
Triangular dark area with its base to tooth surface. A few mm apical from the contact point
adumbration is more likely to be seen in which tooth?
A tooth that is triangular in cross section
Moderate Lesions_ Proximal caries
appears dark triangle with base on Dentin enamel junction and apex directed toward pulp
Moderate Lesions
Lesions extending more than halfway to the pulp
Occlusal Caries location:
Narrow at the occlusal surface, usually at the deepest pit. Wider in Dentin, and looks like upside-down cauliflower,
True or False: Occlusal Caries is easy to detect clinically
True
Cervical (Root) Caries
Diffuse, rounded radiolucency below Cervical enamel junction, associated with gingival recession, more rapid decay of cementum and dentin (softer).
Recurrent Caries
New Caries lesion after removal and restoration of caries lesions.
xerostomia is defined as:
Dry mouth
Xerostomia can come from:
Medications, Therapeutic Radiation, Sjogren’s Syndrome
Xerostomia Caries begins at:
Cervical Region causing extensive decay
Rampant Caries are:
Extensive Caries- encroaches on pulp quickly
Rampant Caries are found on what types of patients:
Pediatric Patients, Patients with poor Diet, Socio-economic factors, Meth use Patients
