  6. A sulcus brush is a
    specific type of brush that has 2 to 3 rows
  7. A _________ brush head may enable better access to posterior teeth
  8. Tufts closely spaced allow the filaments to
    support each other, making the brush firmer
  9. Filaments should be ________ for safety to oral soft tissues and tooth structure
    soft and end-rounded
  10. The firmness/stiffness of a toothbrush depends on the
    • 1.Diameter of the Filament–The smaller the diameter the softer the brush
    • 2.Length of the Filament–The longer the filament the softer the brush
    • 3.Number of Filaments in a Tuft–The more filaments in a tuft and/or the more tufts in a head increase stiffness
    • 4.Angle of Filaments–Angled filaments are more flexible than straight filaments of equal length
  11. Most current toothbrushes have ______ filaments
  12. Natural bristles (animal hair) are unsanitary because the bristle tip
    can not be end-rounded
  13. ________ can occur with the absence of end-rounding
    Gingival damage
  14. What are the two tooth-brushing systems
    • The Count System: The patient counts 5, 6 or 10 strokes in each area
    • The Clock System: 2 minutes
  15. Acquired pellicle reaches its full thickness ____ following brushing. If the acquired pellicle is removed often due to factors such as excessive brushing, it will not be allowed to reach maximal thickness and risk of _______ is higher
    • 2 hours
    • erosion
  16. Negative Effects of Tooth-brushing are frequently found over
    canines and premolars
  17. Acute Lesions usually occur from
    incorrect placement of the brush, stiffness of the filaments or over zealous brushing

    Stillman's cleft

    Contour with a groove or slit that extends from the crest of the gingiva to the attached gingiva
  20. What is dental abrasion and what is it caused by
    • Wedge-shaped indentations with smooth, shiny surfaces
    • results from a repetitive mechanical habit
  21. Most abraded areas are on the
    cervical areas of exposed root surfaces
  22. Most tooth brushing methods are classified based on the
    position and motion of the brush
  23. Which tooth-brushing method is described as Vibratory
    Bass, Charters and Stillman
  24. The distinguishing characteristic of the Bass method is the toothbrush head is placed
    directly beneath the gingival margin
  25. Describe the Bass method
    • 1. Direct the filaments apically at a 45° angle to the long axis of the tooth
    • 2. The tips are lightly pressed into the gingival sulcus (Bass/Below the gum)
    • 3. Vibrate the brush back and forth with very short strokes
  26. What TB method is used for children or when a technique, such as the Bass or Stillman’s is too difficult to master
    Rolling stroke method
  27. What is the technique of the Rolling Stroke method
    • 1. Place the side of the brush on the attached gingiva with the filaments directed apically
    • 2. The filaments are pressed lightly against the gingiva
    • 3. Roll the brush slowly over the teeth
    • 4. The stroke is repeated at least 5 times for each tooth or group of teeth
  28. The Stillman’s Method was designed for
    gingival massage and stimulation
  29. What is the Stillman’s Technique
    • 1. The brush ends are placed partly on the gingiva and partly on the cervical areas of the teeth and directed slightly apically
    • 2. The tips of the bristles are pressed lightly
    • 3. The handle is given a slight rotary motion, and the brush ends are maintained in position on the teeth surface
  30. The modified Stillman incorporates a ________ after the rotary phase
    rolling stroke
  31. In the Charters method, the brush is held with filaments placed against the tooth at approximately 45° toward
    the occlusal or incisal plane of the teeth
  32. What is the Fones tooth brushing method
    • 1.With the teeth closed, the brush is placed inside the cheek over the last maxillary molar, lightly contacting the gingiva
    • 2.Using a wide, circular motion with light pressure the brush moves from the maxillary to the mandibular gingiva (the maxillary and mandibular teeth are brushed at the same time)
    • 3.The anterior teeth are in edge-to-edge contact when brushed with the circular strokes
  33. With the horizontal method the bristles are placed at a ______ to the tooth
    90° angle
  34. Describe the Vertical (Leonard technique)
    • 1. With the teeth edge-to-edge the bristles are placed at a 90° angle to the tooth
    • 2. The bristles are moved in an up-and-down stroke (vertically)
    • 3. The maxillary and mandibular teeth are usually brushed separately
  35. A scrub-brush procedure consists of combining
    horizontal, vertical, and circular strokes, with some vibratory motions for certain areas
  36. The correct method for occlusal brushing is
    Vibrate the brush with light pressure while maintaining filament tips on the occlusal surface
  37. What are some different ways of Disinfecting a Toothbrush
    • 1. Use a UV toothbrush cleaner
    • 2. Store a toothbrush in a 3% Hydrogen Peroxide solution (changed daily, as it turns to water in a matter of hours)
    • 3. Pour a small amount of Listerine into a cup and stir the bristled end of the brush for 30 seconds
    • 4. Place a toothbrush on the top rack in the dishwasher
  38. Power toothbrush motions can be grouped into four general categories:
    • 1. Rotating
    • 2. Counter-rotational
    • 3. Side-to-side
    • 4. Oscillating-rotating
  39. Describe the movement of a Rotating Power Toothbrush
    The entire brush head turns in a full circle, moving in one direction (Rota-dent)
  40. Describe the movement of a Counter-rotational Toothbrush
    The individual tufts rotate in different directions (Interplak)
  41. Describe the movement of Sonic Toothbrushes
    The filaments move side-to-side (Sonicare)
  42. Describe the Oscillating-rotating Toothbrush
    The brush head oscillates from the center point but does not rotate in a full circle (Oral-B)
  43. _________ technologies  are the most commonly used in power toothbrushes today
    Sonic and oscillating-rotating
  44. Systemic Conditions such as ________ may contribute to offensive breath odor
    diabetes, liver and kidney disorders, and pulmonary disease
