1. A look at the new
toothbrush technologies
SUBMITTED BY:
Dr. Ritu Gupta
Intern (Batch 2013-14)

2. HISTORICAL BACKGROUND
 Initially, aromatic plants like chewing twings
were used and Meswak from Arak trees were
used
 Then Chinese invented the modern toothbrush
in the year 1600
 In 1780, William Addis designed a toothbrush
with bone handle and hog bristles
 In 1900, celluloid (plastic) brushes with bone
handle were introduced.
 In World War II – nylon bristles were introduced.

3. ADA SPECIFICATIONS OF A TOOTHBRUSH
THE HEAD OF THE BRUSH SHOULD BE:
a. 1-1.25 inches long
b. 2-4 rows of bristles
c. 5/16 to 3/8 inches wide
d. 5-12 tufts per row
e. 80-60 bristles per tuft

4. DESIGN OF THE TOOTHBRUSH
 A toothbrush consists of handle, shank and
head
 It has bristles, which when bunched together
are called tufts
 The extreme end of the head is toe and that,
close to the handle is the heel.
a. Size- large, medium and small
b. Lateral profile- flat , convex , concave and
scalloped

5. BRISTLES
 2 types of bristles are available, nylon
(synthetic) and natural (hog)
 Nylon bristles are preferred
 Natural bristles are more susceptible to
breakage and fraying, contamination with
bacteria is high

6. HARDNESS
Depends on material, diameter and length.
a. Nylon bristles are more flexible
b. Soft : 0.007-0.009 inches (No. 7,8,9)
c. Medium : 0.010-0.012 inches (No. 10,11,12)
d. Hard : 0.013-0.014 inches (No. 13,14)
e. Extra hard : 0.015 inches (No. 15)
If the bristles are soft , they should be set
close. If they are hard they should be more
widely spaced.

7. HANDLE DESIGN
a. Straight
b. Angulation in the shank
c. Indentation of handle for a better grip
i) Frequency of brushing-every 12 hours
ii) Frequency of change of brush-every 3
months
iii) Length of brushing time- initially 10-20
minutes is required until the patient
becomes
more precise. Later 3-5 min may suffice.

8. BRUSHING MOTIONS IN BRUSHING TECHNIQUES
1.HORIZONTAL
a. Reciprocating (scrub)
2.VIBRATORY
a. Bass method
b. Stillman’s method
c. Charter’s method
3.VERTICAL SWEEPING
a. Rolling stroke
b. Modified Bass
c. Modified Stillman’s
d. Leonard
e. Smith-Bell (physiological technique)
4.Rotary (Fones’) technique

technique should be identified and

must be replaced as soon as the bristles begin
