Further Radiographic Interpretation

Question 1

what are the fundamentals for successful interpretation of radiographs

Answer 1

prerequisite knowledge of radiographic techniques, anatomy and pathology, quality assurance, using a systemic approach, appreciating limitations of the image and identifying when further imaging is required

Question 2

what is the systematic approach you should take when viewing radiographs

Answer 2

overview
teeth
apical tissues
periodontal tissues
bone
other structures

Question 3

what kind of things do you look for in an overview of a radiograph

Answer 3

display issues, technique errors, general findings, foreign bodies

Question 4

what kind of things do you look for when looking at teeth in a radiograph

Answer 4

number, position, development, morphology, condition of crowns and roots

Question 5

what kind of things do you look for when looking at apical tissues in a radiograph

Answer 5

lamina dura, PDL space, abnormal radiolucenices/pacities around apices

Question 6

what kind of things do you look for when looking at periodontal tissues

Answer 6

periodontal bone levels, furcation involvement, crestal bone quality, PDL space, calculus deposits

Question 7

what kind of things do you look for when looking at bone

Answer 7

shape/size/symmetry, cortical bone, trabecular bone, abnormal radiolucencies

Question 8

what other structures do you consider in a radiograph

Answer 8

condylar heads, maxillary sinuses, nasal cavity

Question 9

what is the benefit of a systematic approach

Answer 9

avoids satisfaction of search, tunnel vision and getting side tracked
