Q

Define the term: open contacts

A

on a dental image, appears as a thin radiolucent line between adjacent tooth surfaces

22
Q

Define the term: cervical / gingival

A

the tooth surface towards the gumline/cervical third area

23
Q

Define the term: lingual

A

the tooth surface towards the tongue

24
Q

Define the term: dentin

A

the tooth layer found between the enamel and surrounding the pulp cavity (appears radiopaque)

25
Q

How does calculus appear on an image?

A

radiopaque

26
Q

Define the term: image interpretation

A
  • an explanation of what is viewed on a dental image
  • the ability to read what is revealed by a dental image
27
Q

Define the term: alveolar bone loss

A

a loss of bone that surrounds and supports teeth in the maxilla and mandible

28
Q

Define the term: clinical attachment loss (CAL)

A

the measurement in millimeters of the distance between the cemento-enamel junction and the case of the sulcus or periodontal pocket

29
Q

Define the term: inter-radicular

A

between the roots of adjacent teeth

30
Q

Define the term: lamina dura

A

the wall of the tooth socket that surrounds the root of a tooth (appears radiopaque)

31
Q

Define the term: periodontium

A

specialized tissues that surround and support teeth, such as the gingiva, cementum, periodontal ligament, and alveolar bone

32
Q

Define the term: periodontal ligament space (PDL)

A
  • a space that exists between the root of a tooth and the lamina dura (appears radiolucent)
  • contains connective tissue fibers, blood vessels, and lymphatics
33
Q

Define the term: calculus

A

a stone-like concretion that forms on the crowns and roots of teeth as a result of the calcification of bacterial plaque (appears radiopaque)

34
Q

Define the term: maxillary teeth

A

teeth located in the maxilla or upper arch

35
Q

Define the term: interpretation

A

an explanation

36
Q

Define the term: cementum

A

calcified connective tissue that covers the outer root surface of the tooth

37
Q

Define the term: overlapped contacts

A

on a dental image, the area where the contact area of one tooth is superimposed over the contact areas of an adjacent tooth

38
Q

Define the term: mandibular teeth

A

teeth located in the mandible or lower arch

39
Q

Define the term: periodontal

A

around a tooth

40
Q

Define the term: radiolucency

A

an area on a dental image appears radiolucent ((dark/black) due to readily allowing the passage of the x-ray beam so that more x-rays reach the image receptor

41
Q

Define the term: distal

A

the tooth surface away from the midline of the mouth

42
Q

Define the term: dentino-enamel junction (DEJ)

A

the junction between the dentin and enamel of a tooth

43
Q

Define the term: radiolucent

A

the portion of an image that is dark or black, due to the structure readily permitting the passage of the x-ray beam and allowing more x-rays to reach the image receptor

44
Q

Define the term: mesial

A

the tooth surface towards the midline of the mouth

45
Q

Define the term: intraoral

A

inside the mouth

46
Q

Define the term: periodontal disease

A

a group of diseases that affect the tissues around teeth

47
Q

Define the term: vertical bone loss / angular bone loss

A

bone loss that does not occur in a plane parallel to the cemento-enamel junctions of adjacent teeth

48
Q

Define the term: radiopaque

A

the portion of an image that is light or white, due to the structure resisting the passage of the x-ray beam and limiting the amount of x-rays that reach the receptor

49
Q

Define the term: buccal

A

the tooth surface towards the cheek on posterior teeth

50
Q

List the two terms used to describe the distribution of bone loss on an image.

A
  • localized bone loss
  • generalized bone loss
51
Q

Define the term: anterior

A

towards the front

52
Q

What intraoral image is ideal for diagnosing periodontal disease?

A

periapical image
