Intra Oral films Flashcards
What are image techniques?
detailed cheat sheets for each exposure
How long are adult exposures
0.094 seconds
how long are paediatric exposures
0.062 seconds
what are the purposes of a full mouth survey
decrease error, decrease patient exposures, identify when retakes are necessary
What are bitewings used for
for inter proximal surfaces of posterior teeth
What needs to be visible in mand and max of bitewings
alveolar crests
What colour is used for the RINN instrument for bitewings
RED
What needs to be shown in a premolar bitewing
2-3 mm of the distal of the canine
what needs to be shown in the molar bitewing
the distal of the last molar tooth
what is the purpose of bitewings
to evaluate dentition for caries and periodontal bone loss
In premolar bitewings, what does the beam need to be perpendicular to
the receptor and inter proximal surfaces
in a premolar bitewing, what tip will help to capture whats necessary
line up to the canine and the MB of the first molar
in a molar bitewing, what tip will help to capture whats necessary
line up to the MB of the 1st molar and the MB of the 2M or the 3M
What does a good periapical have
visual on the crown and 2-3 mm surrounding the apices of the imaged dentition and none to little overlapping go dental structures, least amount of distortion
What is the purpose of periapicals
evaluation of dentoalveolar structures for pathology
