radiation benefits Flashcards
Patients who are fearful of the risks
of dental radiography need to be
made aware of what three things?
–The magnitude of the risks (small)
–What we do to minimize risks
(radiation protection for the patient)
–The benefits of the radiographic
examination
Benefits of Dental Radiography
* Interproximal?
* Severity/extent of?
* bone?
* Root?
* Periradicular?
* Basal bone?
* Location of?
* implants?
- Interproximal caries diagnosis
- Severity (depth) and extent of caries
- Periodontal bone loss (i.e., alveolar crest)
- Root configuration
- Periradicular pathology
- Basal bone pathology in jaws
- Location of 3rd molar roots & IAC
- anatomy assessment for implants
finding ip caries
seen as luncencies on the proximal surfaces of teeth
BW very good for this
Bitewing radiographs & caries
- Compared to visual examination
–Digital bitewings identified 3.2 times more carious lesions
–Conventional bitewings identified 2.9 times more carious lesions
–Of the additional decay identified - 6% was occlusal decay
- 94% was proximal decay
determining the serverity and extent of caries
can see how deep caries are and possible pulpal exposure
perio bone loss
can be seen on PAs: possibly vertical or horizontal
can be generalized or localized
can calc be seen with x rays
yes, opaque
L man first molar root incidence rate
- 20% incidence in Asians in a Chinese population (Hong Kong and Taiwan)
- 10-12% in native North American
populations
PA patholgogies and xrays
very useful, often oresent as lucencies
most common where?
common Basal bone pathology in jaws?
Hyperdontia multiple teeth
most common in PM area
neoplasias and xrays
can often see metastises with xrays in oral cavity
systemic dx and xrays
oral manifestations possibly seen (browns tumor)
Location of 3rd molar roots & IAC
impacted thrid molars for extraction
