patient history
clinical examination
what does ALARP stand for and refer to?
as low as reasonably practicable
dose -> amount of radiation absorbed by the patient
remember these can be mistaken for caries
Cervical burnout or translucency
Visual perception - problem of contrast below dense metallic restoration
Air/lip shadow in premolar region
Dentine surrounding radio-opaque zone under amalgam
Radiolucent restorations
what are the red arrows pointing at?
cervical burnout
how often are bitewings taken for a high risk child?
6 monthly
how often are bitewings taken for a moderate risk child?
anually
how often are bitewings taken for a low risk child?
every 12-18 months
how often are bitewings taken for permanent dentition?
24months or more
describe the trabecular pattern of the mandible
○ Thick, close together, horizontally aligned
describe the trabecular pattern of the maxilla
○ Finer, more widely spaced, no obvious alignment pattern
radiographic appearance of initial acute inflammation
No apparent changes or possible widening of PDL space
radiographic appearance of initial spread of inflammation
Loss of lamina dura at apex
radiographic appearance of further inflammatory spread
Periapical bone loss
radiographic appearance of initial chronic inflammation
No bone destruction seen or dense sclerotic bone periapically (sclerosing osteitis)
radiographic appearance of chronic inflammation (long standing)
Well defined, radiolucent area periapically with sclerotic bone surrounding
- Radiolucency sometimes called rarefying osteitis
what does this show?
radicular cyst
