red
B: bitewings
BWX
Anterior periapicals
Captures the full root length and bone surrounding the root apex of anterior teeth
Often distorts relative distances due to angulation of sensor
posterior periapicals
Captures the full root length of posterior teeth and bone surrounding the root apex

mandible
,lower jaw
