Radiology M4 - R3 : periodontology

Question 1

overall assessment of periodontal disease is based on both what

Answer 1

clinical and radiographic examination

Question 2

what would a radiograpgh show, for someone suffering with periodontal disease

Answer 2

would show the amount of bone remaining in relation to length of tooth

Question 3

when measuring bone loss for periodontal disease on a radiograph, it is essential for the following requirements

Answer 3

fine detail required

excellent quality films

not overexposed

well processed if film and correct contrast if digital

Question 4

which technique would be used to see perio endo lesions

Answer 4

vertical bitewing

Question 5

why do we get cervical burnout

Answer 5

cervical burnout appears as a radiolucent band around the neck of teeth and is more prounonced at the proximal edges.

the x-ray photons overpenetrate or burnout the thinner tooth edge and create a radiolucent area that mimics cervical caries

Question 6

if there was uniformed pocketing <6mm, which radiograph would have been used to detect it

Answer 6

horizontal bitewinf

Question 7

if a radiograph shows perio-endo lesions, which radiograph would have been used

Answer 7

vertical bitewings

Question 8

if there was irregular pocketing present which radiograph methods would you use

Answer 8

bitewings +/- paralleling periapicals

Question 9

there is no clear evidence to support any recommendations regarding how often radiographs should be taken for periodontal reasons.

what would be recommended in regards to radiograph

Answer 9

sequential intraoral radiographs should be placed reproducibly/accuratley to allow for radiographic assessment of changes in bone levels

Question 10

which radiographic technique can be used to assess all teeth and their periodontal support

Answer 10

DPT
