most common technique used in dental radiography

dental prophylaxis, mobile tooth, post extraction, FORL

4 reasons for dental radiography

foreshortening

what occurs when xray beam is perpendicular to film (not bisecting angle)

elongation

what occurs when xray beam is perpendicular to long axis of tooth (not bisecting angle)

dorsal recumbency, rotate along z-axis

position for mandibular canines and incisors for dental radiography

lateral recumbency, side of interest up, parallel technique

position for mandibular PM4 and molars for dental radiographs

sternal recumbency, towel under jaw, tube head over nose

high contrast

what type of contrast do you want for skull radiograph

low kVp

how to achieve high-contrast radiographs

lateral structure visualized on the palmar aspect of radiograph

what is the general cheat to what is visualized (and on what surface) in oblique views use example of a DLPaMO view

first 2 letter are xrays entering, second 2 letters are xrays exiting, O is saying not standard view

how to read full oblique views (enter & exit & type of view)

degree angle from ground to xray beam
