Back 2

True

Front 3

Brushes designed as soft, medium or hard are comparatively consistent between manufacturers.

Back 3

False; they are not comparatively consistent

Front 4

End-rounded filaments cause the least amount of trauma to the gingival tissues.

Back 4

True

Front 5

Natural bristles are made of hair of hog or wild boar and are more resistant to accumulation of microorganisms.

Back 5

False; hollow ends allow more microorganisms to accumulate

Front 6

Shorter filaments are stiffer and have less flexibility.

Back 6

True

Front 7

Thicker filaments are softer and more resilient.

Back 7

False; Thinner filaments are softer and more resilient.

Front 8

Angled filaments may be more flexible and less stiff than straight filaments of equal length and diameter.

Back 8

True

Front 9

In the process of end-rounding, each filament is sealed and rounded by heat treatment.

Back 9

True

Front 10

Natural bristles cannot be end-rounded.

Back 10

True

Front 11

The toothbrush selected must be able to be adapted to all facial, lingual, palatal, and occlusal surfaces.

Back 11

True

Front 12

Use of a soft end-rounded brush is more effective in cleaning the cervical areas, both proximal and marginal.

Back 12

True

Front 13

Use of a soft end-rounded brush is applicable around fixed orthodontic appliances.

Back 13

True

Front 14

Soft end-rounded bristles cannot be directed into the sulcus of sensitive gingival areas.

Back 14

False; they are more effective for use on sensitive gingiva

Front 15

The toothbrush handle should be grasped in the palm of the hand with the thumb on the shank.

Back 15

True

Front 16

The direction of filament placement depends on the brushing method used.

Back 16

True

Front 17

Too much pressure bends the filaments and curves them away from the area where brushing is needed.

Back 17

True

Front 18

Brushing should begin from a molar region of one arch around to the opposite side, then back around the lingual or facial.

Back 18

True

Front 19

Each brush placement must overlap the previous one.

Back 19

True

Front 20

An area that is most difficult for brush placement and manipulation is the left side for the right-handed brusher.

Back 20

False; the most difficult area is the right side for right-handed brushers

Front 21

At least two brushings and appropriate interdental care daily are recommended for control of dental biofilm.

Back 21

True

Front 22

The longer in dental biofilm is allowed to remain undisturbed, the greater the pathogenic potential of the biofilm bacteria.

Back 22

True

Front 23

If a patient can only brush once a day, he/she should be encouraged to do so in the morning upon rising.

Back 23

False; before going to sleep

Front 24

The best time for at-home fluoride treatments is after flossing and brushing before bed.

Back 24

True

Front 25

Power toothbrushes move in speeds that cannot be duplicated by manual toothbrushes.

Back 25

True

Front 26

Research has shown that power brushes are not more effective than manual brushes.

Back 26

False; they are

Front 27

The safety of power brushes has been well-established.

Back 27

True

Front 28

Power brushes may be recommended for aggressive brushers.

Back 28

True

Front 29

Power brushes are not indicated for patients with dental implants.

Back 29

False; they are

Front 30

Power brushes can be used by patients undergoing orthodontic treatment.

Back 30

True

Front 31

Dexterity of the patient is not required as extensively with power brushes as it is with manual brushes.

Back 31

True

Front 32

Tongue cleaners may be made of plastic, stainless steel, or flexible metal.

Back 32

True

Front 33

Prolonged omission of techniques of biofilm removal is never indicated.

Back 33

True

Front 34

Abrasion may be defined as the pathological wearing away of tooth substance through some abnormal chemical process.

Back 34

False; Abrasion results from a repetitive mechanical habit

Front 35

Mastication is the primary cause of dental abrasion.

Back 35

False; The primary cause of abrasion is incorrect tooth brushing with an abrasive dentifrice

Front 36

The location of dental abrasion is primarily on facial surfaces.

Back 36

True

Front 37

Most abraded areas on cervical areas of exposed root surfaces, but occasionally they may occur on the enamel.

Back 37

True

Front 38

Brush contamination occurs with use and contamination has the potential for causing systemic or localized infection.

Back 38

True

Front 39

To clean a toothbrush after use, hold the brush head under a strong stream of warm water to force particles, dentifrice, and bacteria from between the filaments.

Back 39

True

Front 40

Brushes should be kept in open air with the head in an upright position.

Back 40

True

Front 41

Portable toothbrushes should be stored in closed containers.

Back 41

False; They need sufficient holes to give air temporarily until brush is dry
