ELECTRIC BRUSH : New Innovation


1. Introduction

Electric brushes, often referred to as electric brushes, , are dental hygiene devices designed to clean teeth and gums more effectively than traditional manual toothbrushes. These brushes have become increasingly popular due to their convenience and ability to provide a thorough and consistent cleaning experience. Here is a detailed description of the concept of electric brushes:

Basic action: Electric brushes are powered by electricity, usually using rechargeable batteries or direct electrical connections. The main feature that distinguishes them from manual toothbrushes is their ability to automatically move the bristle head in either rotating or vibrational motion to help clean teeth and gums.

Electric Brush

Cleaning mechanism:

  • Rotation: Some electric brushes have a small, round brush head that rotates in circular motion. These brushes are designed to mimic the speed of manual brushing, but do so with much greater speed and accuracy.
  • Vibration: Others use high-frequency vibrations to stimulate the bristle head. These vibrations create a pulsating effect, removing plaque and food particles from the teeth and gums.

2. Types of electric brushes and benefits of electric brushes

Electric brushes come in different types, each of which have its own unique mechanism of action and associated benefits. Here’s an overview of the three main types: oscillating, sonic and ultrasonic toothbrushes, as well as how each type works and its benefits: 

  • Oscillating Electric Toothbrush:

How it works:

Oscillating toothbrushes have a small, round brush head that usually rotates or rotates back and forth rapidly in circular motion.

Some oscillating toothbrushes also include pulsed movements in addition to oscillations.

Rotation and pulsation help to remove plaque and debris from teeth and gums.


Effective plaque removal: The oscillating speed provides a thorough and efficient cleaning action, making it easy to remove plaque and maintain oral hygiene.

Ease of use: These toothbrushes are user-friendly, as rotating speed does most of the work, requiring minimal effort from the user.

Timer and pressure sensor: Many oscillating toothbrushes come with built-in timers to ensure users brush for the recommended two minutes. Some also have pressure sensors to prevent excessive force while brushing.

  • Sonic Electric Toothbrush:

How it works:

Sonic toothbrushes use high-frequency vibrations (usually 30,000 to 40,000 strokes per minute) to create a dynamic fluid action in the mouth.

This fluid action generates small bubbles and vibrations, effectively removing plaque and debris from teeth and gums.

The bristle motion in a sonic toothbrush is side-to-side or back-to-side rather than a circular rotation.


Deep cleaning: Rapid vibrations produce a broad action that can reach areas beyond bristle tips, providing a deep and thorough cleaning.

Gum stimulates health: Gentle vibrations can stimulate blood flow to the gums, potentially promoting gum health.

Variety of brush heads: Sonic toothbrushes often come with interchangeable brush heads for a variety of purposes, such as sensitive teeth, whitening or gum care.

  • Ultrasonic Electric Toothbrush:

How it works:

Ultrasonic toothbrushes operate at even higher frequencies, typically more than 100,000 vibrations per minute.

They use ultrasonic waves to create bubbles in toothpaste or mouthwash, which freeze on the surface of teeth, effectively removing plaque and bacteria.


High frequency cleaning: Ultrasonic toothbrushes provide extremely fast vibration and a unique cleaning action, which can be more effective in removing plaque and bacteria.

Benign on teeth and gums: Despite their high frequency, ultrasonic toothbrushes are usually gentle on teeth and gums, making them suitable for individuals with sensitivity.

Reduction of friction: Lack of physical bristle movement reduces the risk of enamel wear and damage to the gums.


In summary, each type of electric brush has its own mechanism of action and benefits:

The choice between these types largely depends on individual preferences and oral health needs, as all three can provide effective cleansing when used correctly.

3. Scientific studies that show the advantages of electric brushes


Several scientific studies have examined the advantages of electric brushes over manual toothbrushes in terms of plaque removal, gum health, and overall oral hygiene. Here are some of the major studies and their findings:

Plaque removal:

A study published in the Journal of Clinical Periodontology in 2005 compared the effectiveness of electric brushes to manual toothbrushes. Researchers found that electric brushes, especially those with oscillating-rotating heads, were more effective at reducing plaque and gingivitis than manual toothbrushes [1].

Another study published in the Journal of Dentistry in 2007 examined the efficacy of plaque removal of sonic toothbrushes compared to manual toothbrushes. Results indicated that sonic toothbrushes were more effective in reducing plaque and improving gum health [2].

Gum health:

Research published in the Journal of Clinical Periodontology in 2011 conducted a systematic review of several studies and concluded that electric brushes, including sonic and oscillating-rotating types, showed a consistently greater reduction in gingivitis and bleeding than manual toothbrushes [3].

A study published in the International Journal of Dental Hygiene in 2019 examined the effects of using an ultrasonic toothbrush on gum health. Researchers found that ultrasonic toothbrushes led to a significant reduction in gum bleeding and improved gum health compared to manual toothbrushes [4].

Compliance and Technique:

A study published in the Journal of Clinical Dentistry in 2019 assessed the brushing technique and compliance of individuals using electric brushes compared to manual toothbrushes. The study found that electric brush users were more likely to follow recommended brushing techniques and maintain better compliance with brushing periods [5].


Children and Special Populations:

Research published in the Journal of Clinical Pediatric Dentistry in 2016 examined the use of electric brushes in children with special needs. The study found that electric brushes were well tolerated and effective in maintaining oral hygiene in this population [6].

It is important to note that while these studies generally support the advantages of electric brushes, specific results may vary depending on the type of electric brush used, the duration of the study, and individual oral health conditions. Additionally, since the publication of some of these studies electric brush technology has continued to progress, potentially improving their effectiveness.

Overall, these studies provide scientific evidence that electric brushes, including oscillating-rotating, sonic and ultrasonic types, may be more effective at removing plaque, improving gum health, and promoting better brushing techniques and compliance than manual toothbrushes.
