Electric Toothbrush Basics

Electric Toothbrush Basics


The electric toothbrush (es. Interplak®) may be a valuable alternative to the manual toothbrush.

Some electric toothbrushes remove plaque more effectively than conventional toothbrushes especially on interproximal tooth surfaces.

In fact, as compared to the manual toothbrush, the electric toothbrush removes a larger quantity of plaque in an equal length of time (Van der Weijden et al. 1993).
It is particularly suitable for patients with limited manual dexterity, those who are lazy, patients with disabilities, and those with a fixed orthodontic appliance, for whom it is an indispensable aid (Mantovani et al. 1996). I always choose electric toothbrushes that clean delicately and I use them at a low speed.

Furthermore, I prefer to recommend electric toothbrushes with a very small head that permit adequate access to all areas of the mouth making the use of the manual single tufted toothbrush, superfluous.

The Interplak® electric toothbrush has instead six independent tufts of bristles, that perform rotary and counter-rotary movements.

This electric toothbrush executes a movement that is sufficiently reduced.
Glavind – Zeuner (1986) e Baab – Johnson (1989) assessed, respectively, the efficacy of the Interplak, concluding that the potential of these single-tufted electric toothbrushes to reduce plaque on the tooth surfaces is equal to that of a complete hygiene kit.


Toothpasteit is advisable to use toothpaste to polish teeth and to clean, refresh, and deodorize the oral cavity.

Toothpastes make it possible to deliver some active agents to the tooth surfaces for preventive and therapeutic purposes.



Toothpastes contain various ingredients, and each of these components has its own function:

• Abrasive substances (e.g. Silica, Alumina, Calcium Phosphate, Calcium Carbonate) polish the tooth surfaces, but they can also scratch them to the extent that it is possible to find lesions on the teeth caused by an excessively abrasive toothpaste.

The abrasive effect of toothpastes should clean adequately without scratching.
Some toothpastes, among them Eburdent®, Elmex ®, declare their degree of abrasiveness, that is, the relative dentin abrasion (RDA=Relative Dentin Abrasion).

• Detergents give the product its foaminess and reinforce the action of the abrasives. The detergent most commonly used is Sodium Lauryl Sulphate.

• Thickeners and emollients, such as glycerin and silicates, prevent the toothpaste from drying out.

• Sweeteners, such as Xylitol and Sorbitol, sweeten the toothpaste.

• Flavorings, such as menthol or aromatic substances with a fruit flavor, make toothpaste more refreshing and pleasant to use. • Active ingredients, such as antiseptics, fluoride, desensitizers and other substances are delivered to the tooth surfaces by means of toothpastes, which are an excellent vehicle.
