Preventive Procedures - Week 5 PP

Question 1

Plaque Control Program

Answer 1

1. Plaque can be kept under control with the use of brushing, flossing, interdental cleaning aids, and antimicrobial solutions
2. A goal of the program is to remove plaque at least once daily
3. The techniques that are selected must be based on the needs and abilities of the individual patient

Question 2

Disclosing Agents

Answer 2

Because plaque is not visible on most teeth, a disclosing agent can be used.

This is an effective aid that allows a patient to actually see plaque on their teeth. Disclosing agents are available in tablet or liquid form.

Question 3

Oral Hygiene Indices

Answer 3

An index is a way to measure a clinical condition/observation in numerical values.
An oral hygiene index is a record of the presence of plaque on the surfaces of the patient’s teeth.

1. Plaque Biofilm Control Record (PCR) or Biofilm Control Record (BCR)
2. Simplified Oral Hygiene Index (OHI-S)

Question 4

Oral Hygiene Indices and Biofilm Control Record

Answer 4

1. Review Medical History - ensure no contraindictions are present (allergies to flavors of dyes)
2. Dry Teeth with Gauze or A/W Syringe
3. Place Vaseline on lips, labial mucosa and white or porcelain restorations
4. For liquid: paint teeth with cotton tip applicator
   For tablets (teeth not dried before): Have patient chew a tablet, swish and spit - rinse
5. Record findings on patients PCR and Calculate Plaque Score

Question 5

Plaque Control Record - Calculation

Answer 5

1. Count total number of plaque containing surfaces
2. Count total number of available surfaces (4 per tooth – do not include occlusal)
3. Multiply by 100 to get plaque score percentage

Total number tooth parts with biofilm divided by (4 x number of teeth present) or # of total surfaces x 100 = % Score

Question 6

Simplified Oral Hygiene Index (OHI-S)

Answer 6

6 teeth are scored (one per sextant)
Scoring is from 0-3 based on tooth surfaces covered by debris.

Question 7

Documentation

Answer 7

1. All observations and treatment completed is documented in the patient’s chart ( it is considered an assessment - assessing patient on how much plaque is in mouth)
2. We will learn more about documentation in upcoming weeks
3. Suggestion: have a small calculator that you can bring to patient preventative clinic to calculate the PCR

Question 8

The two basic types of toothbrushes are:

Answer 8

◦ Manual
◦ Automatic
* Used properly, both types are effective in the removal of dental
plaque - research is divided on which is “better”. More about the user not about the type of brush

Question 9

Infant Toothbrushes

Answer 9

• Very small and soft; should be used as soon as the baby’s first tooth appears in the mouth
• Finger brush can also be used

Question 10

Parts of the manual toothbrush

Answer 10

Handle - part grasped in the hand. Durable, impervious to moisture, low cost, easy to grasp, variety of sizes

Shank - the section that connects to the handle and head. A twist, curve, or offset angle may help with adaptation

Head - Working end; consists of tufts of bristles or filaments, rounded ends. Adjusted to the size of the patient’s mouth

Question 11

Manual tooth brushes

Answer 11

1. Come in many styles of head size, tuft shape, and angle and shape of handle
2. In general, dental professionals recommend soft-bristled brushes (always!!!) because these bristles are gentler to the soft tissues and to any exposed cementum and dentin
3. Nylon bristles are preferred
4. Toothbrushes should be replaced every 8-12 weeks or as soon as the bristles show signs of
   wear or begin to splay outward

Question 12

Characteristics of an Effective Manual Toothbrush:

Answer 12

1. Size, shape, weight, and texture meet individual user’s needs
2. Easily held, used, and disinfected
3. Inexpensive and durable
4. Functional (flexible, comfortable, effective)
5. Appropriate strength, rigidity, and weight.

Question 13

Nylon or Natural Bristles?

Answer 13

The bristles may be nylon or natural.
Nylon is preferred because the ends are rounded and polished, which makes the toothbrush safer. The most important factor that should be ensured is that the toothbrush readily removes plaque without causing tissue damage.

Question 14

End-Rounded Nylon Bristles

Answer 14

Most current toothbrushes have nylon filaments. Some evidence suggests that end-rounded bristles are less abrasive to gingival damage than bristles that are non-end rounded. However current research is inconclusive.

The physical properties of natural bristles cannot be
standardized. Natural bristles cannot be end-rounded.

Question 15

Soft Nylon Brush

Answer 15

1. More effective in cleaning cervical areas
2. Less traumatic to tissue
3. Can be directed into the sulcus
4. Toothbrush abrasion and/or recession prevented or lessened
5. More effective for sensitive gingiva A variety of filament designs are available and may include, but are not limited to, end-rounded, feathered, microfine, and conical shaped.
6. Another factor to keep in mind is that the quality of end-rounding varies in both adult and children’s toothbrushes depending on the manufacturer.

Question 16

Power Toothbrushes

Answer 16

• Have larger handles that contain a rechargeable battery
• The larger handle also makes them useful for patients with physical disabilities
• Automatic toothbrushes use one of several motions, including back and forth, up and down, or circular
• Some models feature pulsating and ultrasonic action
  -Moderate evidence indicates power toothbrushes reduce plaque by 10-20%
  and gingivitis by about 10% compared to manual toothbrushes.
• Rotating oscillating power toothbrushes are more effective than side-to-side
  brushes for reducing plaque and gingivitis.
• Sonic power toothbrushes are not shown to be more effective than other power toothbrush types.
• Power toothbrushes generally cause less damage to gingival tissues than manual brushes, as they often include alerts for excessive pressure.
• Improper use of power toothbrushes can lead to increased abrasiveness.
• Recommendations for toothbrushes should be based on individual patient needs and preferences.

Question 17

Indications for Use of Power Toothbrush

Answer 17

1. Fixed orthodontic appliances
2. Decalcification
3. Uncontrolled oral biofilm and periodontal diseases
4. Extensive prosthodontics or dental implants
5. Dexterity and motivational challenges
6. Gingival recession or noncarious cervical hard-tissue lesions
7. Caregiver responsibilities

Question 18

Factors influencing the selection of a proper manual or power toothbrush

Answer 18

Patient - ability of the patient to use the brush and remove dental biofilm from the tooth surfaces without damage to the soft tissue or tooth structure, manual dexterity of the patient, age of the patient

Gingiva - status of gingival and periodontal health, anatomic configurations of the gingiva

Position of the teeth - crowded teeth, open contacts

Compliance - patient preference may dictate which brush is recommended, patients may have preference and may resist change, patients may lack motivation, ability of willingness to follow the prescribed procedure

Power toothbrush - replaceable brush head, features that include a timer and pressure sensor, patient affordability

Question 19

Fones (Tooth Brushing Method)

Answer 19

-Circular method/motion
-usually for young children, toddlers, and patients with decreased dexterity
-bring anterior teeth end-to-end emphasizing getting all teeth
-for lingual surfaces we do an in-and-out stroke

Question 20

Rolling (Tooth Brushing Methods)

Answer 20

Cleaning gingiva, removal of
dental plaque, materia alba and
food debris from the teeth without focusing on the sulcus

Place brush apically close to
attached gingiva and apply slight
pressure and roll down or up

Usually used in combination with another technique

Question 21

Modified Bass (Toothbrushing method)

Answer 21

The most widely accepted method for plaque removal adjacent and
directly below the gingival margin

Removal of dental plaque at the
cervical third

The brush is placed at 45 degrees
apically with 1-2 bristle rows
directed into the sulcus very gently

Vibrate the brush back-and-forth
for 5-10 strokes without removing the brush tips from the sulcus
Roll down or up after vibration

Question 22

Modified Stillman (Tooth Brushing Method)

Answer 22

Ideal for individuals that have
recession
Removes plaque and massages
gingiva
Bristles help at 45 degrees apically and partly on the attached gingiva
Flex bristles so tissues blanch slightly
Vibrate gently, keeping the tips of
bristles in position
Roll down or up after vibration

Question 23

Charters (Tooth Brushing Method)

Answer 23

Patients receiving orthodontic treatment
Patients with prosthetic appliances
Individuals with severe loss of
interdental papillae height

Question 24

Toothbrushing for Acute Oral Inflammatory or Traumatic Lesions

Answer 24

Brush all areas of the mouth not affected and if tolerable clean the affected area with an extrasoft toothbrush. Reducing the bacterial load is essential to aid in healing.
Rinse with a warm saline solution to encourage healing and debris removal.
Consider prescribing an antimicrobial rinse like chlorhexidine to aid in the reduction of
bacterial load until normal oral self-care can
resume.
Resume regular biofilm control measures on the affected area as soon as possible.

Question 25

Toothbrushing following periodontal surgery

Answer 25

Perform oral self-care in the areas not involved in the surgery as usual.
Follow directions provided by the
periodontal office for care of the surgical area.
Rinsing and brushing the surgical area may not be recommended until at least 24 hours after surgery care should be taken to avoid the gingival areas when brushing. If gingival grafting was done, no brushing may be
allowed until the postoperative follow-up appointment.

Question 26

Toothbrushing following dental extraction

Answer 26

Clean the teeth adjacent to the extraction site the day following surgery.
Brush areas not involved in the surgery, as usual, to reduce biofilm and promote healing.
Beginning 24 hours after surgery, rinse the mouth with a warm, mild saline solution after each meal or snack to help remove
food debris from the extraction site.

Question 27

Oral Self-Care for the Neutropenic

Answer 27

Patient Neutropenia or a low white blood cell count (<500 absolute neutrophil count)
occurs during treatment such as
chemotherapy, radiotherapy, and bone marrow transplant associated with many
cancers. Neutropenia puts the patient at increased risk for life-threatening infection.

Question 28

Tongue Cleaning/Brushing

Answer 28

• Doral surface of tongue hosts an abundance of organisms
• Halitosis (bad breath): common
  patient complaint
• Tongue cleaners, or scrapers, are designed and intended for
  removal of debris and bacteria
  from tongue’s dorsal surface
• Brushing tongue with toothbrush also can remove bacteria and debris

Question 29

How do the public and dental professionals make informed choices about oral healthcare products?

Answer 29

The ADA and CDA work to evaluate and interpret information regarding:

1. Safety and efficacy
2. Promotional claims
3. Proper use of dental products
4. Both for public and professional use

The CDA reviews manufacturer submissions to verify the research methodology and evidence that the manufacturer’s statement of claim can be scientifically supported.
These reviews will evaluate the data from all clinical and laboratory tests mentioned in the submission. The CDA may also require additional data to be gathered for
further testing.

2. Contour of Gingival Tissue: The shape and health of the gums can affect the ease
   of flossing; certain types may be better for sensitive or irregular gum contours.
3. Roughness of Interproximal Surface: Rough surfaces may require more durable
   floss to withstand abrasion and effectively remove plaque.
4. User’s Manual Dexterity and Preference: Individual comfort and skill level in handling floss can influence the choice, with some preferring traditional floss and others opting for floss picks or other alternatives.

Question 36

Waxed vs. unwaxed dental floss

Answer 36

Research has shown no difference in the effectiveness of waxed or unwaxed floss for biofilm removal however, the effectiveness of flossing for biofilm removal is not supported by evidence

Question 37

(PTFE) Floss

Answer 39

Monofilament PTFE is used for biofilm removal from proximal tooth surfaces.

Question 40

Flossing Steps

Answer 40

1. Hold a 12- to 15-inch length of floss with the thumb and index finger of each hand; grasp firmly with only 1/2-inch of floss
   between the fingertips.
2. The ends of the floss may be tucked into the palm and held by the ring and little finger, or the floss may be wrapped around
   the middle fingers

Question 41

Flossing “Loop Method”

Answer 41

A circle of floss or “floss loop” may be made by tying the ends together; the circle may be rotated as the floss is used

Circle of Floss. The ends of the
floss can be tied together for
convenient holding.

A child may be able to manage
floss better with this technique.

Question 42

Prevention of Flossing Injuries

Answer 42

Location:
Floss cuts or clefts occur primarily on facial and lingual or palatal surfaces directly beside or in the middle of an interdental papilla. They appear as straight-line cuts beginning at the gingival margin and may result in a floss cleft if the tissue is repeatedly injured.

Causes
* Using a piece of floss that is too long between the fingers when held for insertion.
* Snapping the floss forcefully through the contact area.
* Not curving the floss about the tooth adequately and cutting into the gingival margin.

Question 43

Flossing for Children

Answer 43

1. Importance: Flossing helps remove plaque and food particles between teeth where brushes can’t reach, reducing
   the risk of cavities and gum disease.
2. Age Recommendations: Children should start flossing as soon as they have two teeth that touch. This typically occurs around age 2-3.
3. Parental Guidance: Young children need help with flossing until they can handle it on their own, usually around age 8-10. Parents should assist and supervise.
4. Techniques: Use a gentle sawing motion to slide the floss between teeth, and curve it around each tooth to clean below the gumline.
5. Floss Picks: Consider using floss picks or devices designed for kids to make the process easier and more engaging.
6. Education: Teach children the importance of flossing through fun activities or by setting a good example with their
   own dental care routine.
7. Regularity: Encourage daily flossing, ideally before bedtime, to instill good habits early on.
8. Dental Visits: Regular check-ups with a dentist can reinforce the importance of flossing and provide personalized
   guidance

Question 44

Dental Flossing Limitations

Answer 44

1. Technique Sensitivity: Proper technique is crucial; incorrect use can lead to gum injury or ineffective cleaning.
2. Access Issues: Some individuals may have difficulty accessing certain areas of their mouth, making flossing challenging.
3. Time-Consuming: Flossing can be seen as time-consuming, leading some people to skip it.
4. Discomfort: Some may experience discomfort or bleeding when starting to floss, which can discourage consistent use.
5. Not Always Effective: Flossing may not adequately clean areas with tight contacts or gaps that are too wide.
6. Children’s Compliance: Younger children may resist flossing or not do it correctly without parental supervision.
7. Cost of Alternatives: Some may find alternatives, like water flossers, more expensive and not as accessible.
8. Misunderstandings: Many people might not understand the importance of flossing, leading to inconsistent habits.
9. Limited Impact on Certain Conditions: Flossing alone may not significantly reduce issues like periodontal disease if other factors (e.g., genetics, overall dental hygiene) are at play
