22. The basic principles and tools of the mechanical plaque control

Question 1

1. What is the role of mechanical plaque control?

Answer 1

1/ Prevention of periodontal diseases
2/ Treatment of periodontal diseases

Question 1

2. What are the basic principles of mechanical plaque control?

Answer 1

Each person is different! As is each mouth, each tooth and each interdental space. For that reason, optimal teeth cleaning needs to be adapted to the individual anatomy, age and ability of each person.

• atraumatic
• effective
• acceptable

Question 2

3. List the tools for mechanical plaque control

Answer 2

1. Toothbrush – manual, oscillating, sonic
2. Floss
3. Interdental brush
4. Water flow (woodpecker)
5. US tool (cavitron)

Question 3

3. Tools for mechanical plaque control
   a/ How is brushing participate in mechanical plaque control?

Answer 3

Bass technique. 50%-tooth, 50% - gingiva coverage.

For labial/buccal and oral surfaces
- Toothbrush at 45 degrees
- Bristles projecting into pockts
- Using smooth circular motion
- From gum to occlusal surface

For occlusal surfaces:
- Forward and backward movements;
- swiping from fissures towards the cusps

Question 4

3. Tools for mechanical plaque control
   b/ How does solo toothbrush participate in mechanical plaque control?

Answer 4

solo toothbrush for hard to access areas

Question 5

3. Tools for mechanical plaque control
   c/ What are the interdental aids for mechanical plaque control?

Answer 5

sulcus cleaning and gingival stimulation

Question 6

3. Tools for mechanical plaque control
   d/ How does US tool (cavitron) mechanical plaque control?

Answer 6

professional removal with US tool and polishing of the surface to prevent / reduce plaque adhesion.

Question 7

3. Tools for mechanical plaque control
   e/ Characteristics of manual toothbrush

Answer 7

• Small head
• Soft and dense bristles

Question 8

3. Tools for mechanical plaque control
   f/ Characteristics of electric toothbrush

Answer 8

That makes rapid automatic bristle motions
- back-and-forth oscillation
- or rotation-oscillation (where the brush head alternates clockwise and counterclockwise
rotation),
- Motions at sonic speeds or below are made by a motor.

Question 9

3. Tools for mechanical plaque control
   g/ Characteristics of Ultrasonic toothbrush

Answer 9

• is an electric toothbrush that operates by generating ultrasound in order to aid in removing plaque and rendering plaque bacteria.
• work by generating an ultrasonic wave usually from an implanted piezo crystal, the frequency of which technically could begin at 20,000 Hz (2,400,000 movements per minute).
• typically operates on a frequency of 1.6 MHz, which translates to 96,000,000 pulses or 192,000,000 movements per minute

Question 10

3. Tools for mechanical plaque control
   I/ Advantages of powered toothbrush (automatic or mechanical or electric toothbrush)

Answer 10

1. It increases patient motivation resulting in better patient compliance
2. Increased accessibility in interproximal and lingual tooth surface
3. No specific brushing technique required
4. uses less brushing force than manual toothbrushes
5. Brushing timer is incorporated in some brushes to help the patient in brushing for the required duration
