Q

Define the term: periapical cyst / radicular cyst

A

a lesion characterized by an epithelial-lined cavity or sac located around the apex of a nonvital tooth that results from pulpal death (appears radiolucent)

a well-defined radiopacity seen below the apex of a nonvital tooth that has a history of long-standing pulpitis (appears radiopaque)

30
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

31
Q

Define the term: anterior

A

towards the front

32
Q

Define the term: unilocular noncorticated

A

describes a radiolucency on a dental image that exhibits one compartment without a well-defined outer border

33
Q

Define the term: unilocular coriticated

A

describes a radiolucency on a dental image that exhibits one compartment with a well-defined outer border

34
Q

Define the term: distal

A

the tooth surface away from the midline of the mouth

35
Q

Define the term: apical

A

towards the apex of a tooth

36
Q

Define the term: periapical lesion

A

a lesion located around the apex of a tooth

37
Q

Define the term: multilocular

A

a term used to describe a radiolucent lesion on a dental image that exhibits multiple compartments

38
Q

Define the term: periapical

A

around the apex of a tooth

39
Q

Define the term: interpret

A

to offer an explanation

40
Q

Define the term: occlusal

A

the chewing surfaces of posterior teeth

41
Q

Define the term: radiopacity / radiodensity

A

an area on a dental image appearing radiopaque (light/white) due to resisting the passage of the x-ray beam and limiting the amount of x-rays that reach the image receptor

42
Q

Define the term: periapical abscess

A

a lesion characterized by a localized collection of pus around the apex of a nonvital tooth that results from pulpal death (appears radiolucent)

43
Q

Define the term: vital

A

living

44
Q

Define the term: anterior teeth

A

central incisors, lateral incisors, and canines/cuspids

Q

Define the term: pulp stones

A

calcifications found in the pulp chamber or pulp canals of teeth (appear radiopaque)

46
Q

Define the term: periapical granuloma

A

a lesion characterized by a localized mass of granulation tissue around the apex of a nonvital tooth (appears radiolucent)

47
Q

Define the term: sclerotic bone / osteosclerosis / idiopathic periapical osteosclerosis

A

a term used to describe a well-defined radiopacity viewed on a dental image located below the apices of vital, noncarious teeth

48
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

teeth located in the maxilla or upper arch

Q

Define the term: incisal

A

the chewing edge of anterior teeth

A

a term used to describe a radiopacity viewed on a dental image that has irregular, ill-defined borders

53
Q

Define the term: apex

A

the area of a tooth that allows for blood vessels and nerves to enter the tooth and maintain the vitality of the tooth

54
Q

Define the term: dentin

A

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

55
Q

Define the term: buccal

A

the tooth surface towards the cheek on posterior teeth

56
Q

Define the term: maxilla

A

the upper jaw

57

Q

Define the term: pulp cavity

A

a cavity within a tooth that includes both the pulp chamber and the pulp canals, containing blood vessels, nerves, and lymphatics (appears radiolucent)

61
Q

Define the term: physiologic resorption

A

resorption of the teeth associated with the normal shedding of deciduous teeth

Define the term: nonvital

A

not living

63
Q

Define the term: alveolar bone
