Q

Transillumination according to the medical dictionary

A

Shining of a bright light through a body part or an organ to check for any abnormalities

17
Q

Shining of a light diagnosis procedure is helpful in detecting what diseases?

18
Q

What can be used in transillumination?

A

Pilot light or Operative light

Fiber optic light - Light cure

19
Q

What does FOTI stand for?

A

Fiber optic transillumination

20
Q

What is the rule in radiography?

A

If something is obvious clinically, Do NOT do radiographic examination anymore

21
Q

What is are the 2 types of radiographs usually used in dentistry?

A

Periapical and Bitewing

22
Q

Describe Periapical radiograph

A

At least 2 to 3 mm of periapical tissue
Shows either maxillary or mandibular
Central ray is focused on the apices

23
Q

Describe the bitewing

A

Takes an image of one side

Crowns and portions of the root are seen of both maxillary and mandibular

24
Q

What is the preferred radiograph in detecting caries?

25
Q

What is the concept of radiography?

A

Becomes sharper than the rest

26
Q

What are the radiographic classification of caries?

A

Interproximal
Occlusal
Buccal and Lingual
Root

Rampant
Recurrent
Radiation

IOBR RRR

27
Q

Interproximal caries is usually found between the __________ and __________

A

Contact point and free gingival margin

28
Q

What is the difference between contact point and contact area?

A

Contact point - Anteriors

Contact areas - Posteriors

29
Q

What is cervical burnout?

A

Radiographic phenomenon that should be differentiated from interproximal caries
It is found all through out the radiograph and is due to the invagination of the proximal root surfaces
it is the darkening of the cervical portion of the tooth

30
Q

Describe Incipient, Moderate, Advanced and Severe interproximal caries

A

Incipient - Less than halfway through the enamel
Moderate - More than halfway but not including the DEJ
Advanced - Less than halfway through the dentin
Severe - Extends through the enamel, dentin and more than half the distance to the pulp

31
Q

Occlusal caries can only be detected once _____________?

A

it reaches the DEJ

32
Q

This appears as a thin radiolucent line below the enamel

A

Moderate occlusal caries

33
Q

This caries is clinically cavitated

A

Severe occlusal caries

34
Q

Why are buccal and lingual caries better detected clinically?

A

Pulp is radiolucent and caries is also radiolucent so it will be dark on dark

35
Q

This appears as a cupped out or cratered out radiolucency found just below the CEJ

A

Root caries

36
Q

Recurrent caries is also known as

A

Secondary caries

37
Q

Why are radiographs used in Rampant caries?

A

To detect the extent of the injury and the tooth structures involved
