This document discusses different types of toothbrushes, including classifications based on length, bristle diameter, and head and bristle designs. It also covers modifications to toothbrush handles and heads over time. Sonic and ionic toothbrushes are described as using high frequency vibrations or charged ions, respectively, to aid in plaque and bacteria removal. The document recommends replacing toothbrushes every 3 months and discusses various methods for disinfecting toothbrushes, including chemical treatments and UV light sanitization. Finally, it reviews several studies that have compared the plaque removal effectiveness of worn versus new toothbrushes and high versus low brushing forces.
8. Sonic Toothbrushes
8
These types of toothbrushes produce high frequency vibrations
(1.6MHz)which leads to the phenomenon of cavitation and
acoustic micro streaming. This phenomenon aids in stain
removal as well as disruption of the bacterial cell wall
(bactericidal).
9. Ionic Toothbrushes
9
Ionic toothbrushes change the surface charge of a tooth by
an influx of positively charged ions.
11. Brush Replacement
11
Frequent replacement recommended; every 3 months
Brushes need to be replaced before filaments become splayed or frayed
or lose resiliency.
Brush contamination occurs with use.
Patients who are debilitated, immunosuppresed, have a known
infection can be advised to disinfect their brushes or use disposable
brushes.
13. Modes of Disinfection
1. Chemical disinfectants.
2. Brush sprays.
13
3. UV light tooth brush sanitizers.
14. Chemical Disinfectants
Nelson et al. (1994)
1% sodium hypochlorite
0.12% chlorhexidine gluconate
Caudry et al.
1% Virkon,
Listerine,
Cepacol,
Scope
Plax
14
15. Brush Sprays
15
Brushtox is a disinfecting or decontaminating
solution, consisting of activated ethanol (40%) with
biocide parabens
16. Ultraviolet Sanitizers
16
These products eliminate the pathogens by a constant stream
of UV light for 3 min.
1. Steam cycle.
2. Dry heat cycle.
17. Brush Storage
17
Open air – upright position, apart from contact with other brushes.
Portable brush containers – with sufficient holes.
At least 6 feet away from the toilet.

Impact of progressive wear of toothbrush on plaque control
Each individual is capable of maintaining good oral hygiene
with a low plaque index even by using a toothbrush that
shows evidence of wear.

High & low brushing force in relation to plaque
removing efficacy & gingival abrasion.
Use of high force is less efficient in plaque removal as
compared to low force where as the difference in the
incidence of gingival abrasion was negligible when
comparing the two forces.

Compare the efficacy of sonic & ionic toothbrushes
The sonic toothbrush was better than ionic toothbrush but
the difference was statistically insignificant.

Comparison of the clinical effectiveness of a single &
double headed toothbrush
The double headed toothbrush was equally as
efficient as a single headed toothbrush in removing
dental plaque from the buccal surfaces but
significantly more efficient on the lingual surfaces.

History – Gold toothpicks from mesopotamia in 3000 BC to the invention of first toothbrush by William Addis in the year1780…followed by the invention of the first nylon bristle toothbrush by DuPont in 1938 to the first electric toothbrush, Broxodent, in 1954…which was invented in switzerland.
Design of a toothbrush – parts included the handle, shank & the toothbrush head – the toothbrush head further included the toe, the heel, the bristles together forming tufts and the brushing plane i.e. the surface formed by the free ends of the bristles or filaments.
15 to 19 cm – adult
Soft bristle - 0.2mm (0.007inch)
Medium bristle - 0.3mm (0.012 inch)
Hard bristle - 0.4mm (0.014 inch)
Softer bristles are more flexible, clean slightly below the gingival margin & reacH farther onto the proximal surfaces.
The offset and angled offset keep the bristles in line with handle.
evaluated a brush with a 17-degree angulation handle and compared it with the same brush with straight handle. A significant improvement in plaque removal was found out by the angulated one.
Long handle brushes > Short handle brushes
Colgate 360° is an advanced design manual toothbrush which includes the following bristle features: cleaning tips on the heel and toe of the brush for cleaning in hard to reach areas; polishing cups to hold toothpaste against the teeth; and vertical tapered bristles for interdental cleaning.
Philips Sonicare is based on patented sonic technology.
Sonicare achieves its bristle velocity through a combination of high frequency and high amplitude bristle motions. These motions create dynamic cleaning action that drives fluids deep into the tight spaces between your teeth and along the gum line, which results in a cleaner, healthier mouth.
Bristles are placed at precise angles to maximize coverage. Finally, it uses extremely soft bristles that are rounded at the top by a diamond grinding wheel, to create a safe and gentle brush head that effectively delivers a powerful clean.
Dual Charging System: Charging glass and travel case.
Sensitive Mode: Gentle teeth and gum cleaning
The plaque with a similar charge is thus repelled from the tooth surface & is attracted by the negatively charged brush.
Instead of cleaning the teeth, it might be contaminating it.
As clinicians, one must take utmost care in our daily disinfection procedures for our instruments and working environment. However, one often neglects to disinfect the one that is used to clean our mouth daily, that is, toothbrush.
Clean thoroughly after each use.
Hold brush under strong stream of warm water from faucet to force particles, dentrifice and bacteria from between the filaments.
Tap the handle on the edge of sink and completely remove the excess water.
Use one toothbrush to clean another brush.
C. albicans, Mycobactrium, M. Bovis & Streptococcus mitis.
Virkon and Listerine
killed all the test species and virtually all microorganisms on
toothbrush bristles. Soaking toothbrush in Listerine for 20 min
is sufficient to eliminate bacterial contamination.

Steam cycle starts automatically when you add water. Your toothbrush is being sanitized when you see and hear steam filling the chamber.
Dry heat cycle follows automatically and keeps your toothbrush sanitized in the clean chamber until your next brushing.
However, costs are a little prohibitive.
Under usual conditions of storage, tooth brushes can be a source or a vector for transmission or reinfection of diseases such as herpes or periodontopathogenic microorganisms and coliforms from bathroom environment
enteric bacteria dispersed via aerosols from toilet flushing
Plaque removal by worn toothbrush…3 month double – blind study…20 students selected…12 teeth selected one molar , one premolar & one incisor in each quadrant.
3 times a day. Two groups.
No significant difference.
35 subjects selected….baseline index…brushed by hygeinist in two randomly selected contra-lateral quadrants for 60s wither either a low force 1.5N or High force 3.5N…the alternative force was used in opposing quadrant.
Significant difference seen in force…but not in abrasion.
22 subjects selected…single blind split mouth study over a period of 45 days was carried out…PI…GBI…GI…recorded after every 15 days…subjects advised to brush twice daily for 3 minutes.
3 way blind cross over study method carried out with 39 patients
the most stylish and futuristic toothbrush/toothpaste contraption on the market today. The toothpaste is self dispensing and easily refillable by turning the handle one direction which creates a suction, bringing the toothpaste into the handle. There is a nozzle below the bristles that delivers toothpaste by turning the end cap the other way– and of course the top is a watertight cap which doubles as a rinsing cup.
Massage gums, teeth whitening, kids to old age patients, bristles are replaced by sponge
This toothbrush incorporates a toothpaste deposit; before you brush your teeth, just twist the grip to push up the toothpaste onto your toothbrush.
This Steward Oralcare toothbrush by Emami comes with toothpaste, mouthwash and floss.
This high-tech toothbrush comes integrated with a camera and a UV system; while you brush your teeth the camera takes the images that are displayed on the side screen on the mirror simultaneously. The UV light keeps your toothbrush clean while the camera lets you know the state of your teeth.
