• Dental professionals must become familiar with the many
available products to advise patients appropriately

23. • Conforms to individual patient requirements
• Easily and efficiently manipulated
• Is readily cleaned
• Is durable and inexpensive
• Flexible, soft, and of strength, rigidity and lightness
of the handle
• Has end rounded filaments or bristles

24. Complete tooth brushing instruction for patients involves teaching;
• What, when, where and how
• The grasp of the brush
• The sequence and amount of brushing
• Supplementary brushing for occlusal surfaces
and the tongue
• Effect from improper brushing

3. Short head (about 2.5cm) with flat brushing surface
(2.5x0.5cm) to permit access to all surfaces of the teeth.

times a day ….

32.  The Bass Method
 The Rolling Stroke
 The Stillman’s Method
 The Charters Method

33.  Position the filaments
up toward the root at
a 45° angle to the teeth.
 Place the brush with
the filament tips
directed into the
gingival sulcus.
Bass Method

34.  Using a vibratory stroke brush back and forth
with very short strokes for the count of ten.
 Reposition the brush to the next group of
teeth.

35.  Direct the filaments
toward the root of the
tooth.
 Place side of the brush
on the gingiva and
have the plastic part of
the brush even with the
tooth.

36.  When the plastic portion is even with the
tooth press the filaments against the gingiva
and roll the brush over the teeth.
 The wrist is turned slightly and the filaments
follow the contours of the teeth.

37.  Like the Bass Method the
filaments are placed at a
45° angle to the tooth.
 Unlike the Bass Method the
filaments are placed half in
the sulcus and half on the
gingiva.
 The same stroke is used as
the Bass.

38.  Position the filaments
toward the chewing
surface of the tooth.
 Place the sides of the
filaments against the
enamel and angle
them at a 45° to the
tooth.

keeping the filaments against the tooth.
