35
Q

Which teeth have a triangular shape from the MD view?

A

anteriors

36
Q

Which teeth have a trapezoidal shape from the MD view?

A

Max Posterior teeth

37
Q

Which teeth have a rhomboidal shape from the MD view?

A

Mand posterior teeth

38
Q

Proximal Convexity

A

creates contacts (football player shoulders)

39
Q

Importance of contacts

A

-arch stability
-prevent food impaction
-protect from perio disease
-prevents premature restorative failure
-prevents proximal caries

40
Q

T or F: Contact area increases in size with age

A

True, broadens due to abrasion (proximal surfaces adjacent teeth rubbing against each other)

41
Q

T or F: All contacts are in the middle 1/3 of the tooth and the same size throughout the mouth.

A

False, location of contacts start more incisal in the anterior and move more cervical posteriorly. They also get larger.

42
Q

T or F: Mesial distal length of the dental arch stay the same over time.

A

False, the arch becomes shorter due to abrasive action. Teeth move mesial toward midline

43
Q

Types of embrasures

A

View from FL: I/O and cerival
View from I/O: B and L

44
Q

F and L Height on Contour

A

AKA Crest of Curvature, greatest area of contour inciso cervically on F and L surfaces. Seen from proximal aspect.

45
Q

T or F: The height on contour may be in a different 1/3 of the tooth on different sides of the tooth

A

True, lingual tends to be more I/O in the posterior than the facial (middle 1/3 instead of cervical)

46
Q

What happens with excessive height of contour?

A

food deflected away too much from gingiva, result in break down inadequate stimulation

47
Q

What happens with insufficient height of contour?

A

gingiva not protected and injury, breakdown

48
Q

Cervical Lines

A

stable entity, Line where enamel and cementum meet, cements-enamel junction.

49
Q

T or F: The Gingival Line is an imaginary line which marks the level of termination of non-attached soft tissue surrounding the tooth

A

true

50
Q

T or F Depth of cervical line curvature on any tooth is normally greater on the mesial as compared to the distal

A

True

51
Q

T or F Cervical lines on proximal surfaces of adjacent teeth have similar depth of curvature

A

true

52
Q

T or F Depth of Curvature of all surface in smallest on central incisors and increases posteriors

A

False, GREATEST on central incisors and DECREASES posteriorly

53
Q

Which hepatitis has no vaccine but has a medical treatment/cure?

A

Hep C

54
Q

How long should you clean your hands with soap or hand sanitizer?

A

15 seconds or until dry

55
Q

A

hives

56

erythema

A

redness

57
Q

T or F Contact dermatitis is a delayed hypersensitivity

A

true, 6-72 hours after contact

58
Q

What other dental products, other than gloves, can contain latex?

A

ambu bags, elastic waistbands and wristbands, mask/ear loops, nitrous masks, orthodontic elastics, rubber dams, prophy cups, syringe tips

59
Q

T or F: A mask must be worn during any treatment when splatter or aerosol is created

A

True

60
Q

T or F A complete face shield protects from splatter but not aerosols

A

True

61
Q

T or F A face shield must be cleaned between each patient

A

True

62
Q

Protective eyewear does not need side shields when an aerosol is being produced

A

False

63
Q

Signs are required anywhere lasers are in use

A

True

64
Q

Contaminated reusable clothing cannot be laundered at home

A

true, must be by professional cleaner or in the office

65
Q

Protective clothing should be changed between patients and can be worn throughout the office

A

FALSE, changed daily and only worn in clinical area

66
Q

Which type of virus is harder to kill: lipophilic or hydrophilic

A

hydrophilic because they are coated in a protein that protects them

67
Q

Biological testing of the sterilizer must be done when?

A

Once a week or whenever an implant is sterilized

68
Q

T or F dentinal bonding agents are flammable

A

True

69
Q

Conditions that predispose you to latex allergy

A

spina bifida, urogenital anomalies, allergies to avocado kiwi nuts bananas

70
Q

Hepatitis that is fecal-oral

A

Hep A, can also be drug use, sex, or transfusion

T or F Hep A vaccine can be administered after exposure

A

True, within 2 weeks post exposure

72
Q

How long hep B can survive outside the body

A

7 days and up to a month in the right conditions

73
Q

T or F Hep C is not transmitted efficiently through occupational exposure to blood

A

True

74
Q

How long is HIV effective outside the body?

A

Once dried only within a few hours becomes very ineffective

75
Q

Alcohol based gels must be at least ____ ethyl alcohol for cleaning your hands

A

62%

76
Q

T or F Isopropanol is more effective than ethyl alcohol

A

FALSE, ethyl alcohol is more effective
