Intro to Interpretation + Reporting

Question 1

What 2017 publication of regulates that clinical evaluation of the outcome of each radiographic exposure must be recorded?

Answer 1

IRMER

Question 2

Who must record the evaluation of the outcome of each radiographic exposure

Answer 2

the dentist

Question 3

What are the three grading classifications of radiographs

Answer 3

1 = excellent
2 = diagnostically acceptable
3 = unacceptable (state why)

Question 4

What observations will you comment on regarding the dentition in a radiograph

Answer 4

• general statement (type of dentition)
• heavily / moderately / minimally restored
• retained roots / associated pathology
• RCTs (comment on obturation / condensation)
• restoration defects
• caries (location + depth)

Question 5

What observations will you comment on regarding periradicular changes on a radiograph

Answer 5

• location
• size
• margins
• what the changes signify
• suggest further investigation or tx if req.

Question 6

Radiographic report

Answer 6

4 bitewings (grade 1)
Periapicals of 11, 21, 36 (grade 1)
Moderatley restored adult dentition, inc. RCT 11 + 21
Unerupted 48, distoangular (if tx indicated - periapical req.)
Mild horizontal bone loss, stage 1
Caries 27M, probably involving pulp, periapical req. if endo being considered
11 + 21 RCT, good obturation length, no periradicular changes

Question 7

radiographic report

Answer 7

Periapicals 23-27
Anterior grade 1
Posterior grade 2 (due to occlusal plane tilt)
24 pinned restoration, circular periapical radiolucency, approx 6mm diam, indicating periapical periodontitis + probably periapical granuloma
25 opacity around root indicative of hypercementosis

Question 8

What is the collar around tooth 25

Answer 8

collar is of same material + dentisty of root
therefore, it is cementum
HYPERCEMENTOSIS

Question 9

radiographic report

Answer 9

CBCT for impacted 48
48 mesioangular, partially erupted + grossly carious
2 roots, curving towards each other, mesial root apical portion curves under distal apex
46 RCT with evidence of poor obturation
46 clear periapical radiolucencies, approx 5-7mm, probable periapical granulomas, re-RCT if req.

Question 10

This radiograph shows a widened PDL space. Second radiograph (LHS) was taken to check for adequate obturation - it shows mesial perforation. Using parallax, is the perforation mesio-buccal / mesio-palatal / mesial?

Answer 10

SLOB = same lingual, opposite buccal

Mesio-palatal

Question 11

What does the acronym SLOB stand for?

Answer 11

Same Lingual Opposite Buccal

Question 12

What is causing the radiopacities seen in the whole anterior section between 16-26
A) retained roots
B) out of focus teeth
C) ghost image from cervical spine
D) denture teeth

Answer 12

Denture teeth

(See clasp on 26)

Radiographer probably didnt notice so didnt tell Pt to remove

Question 13

What is causing the more radiolucent lower half of 12-22

Answer 13

non-carious tooth surface loss

(typical feature suggesting erosive changes)
