Tooth brushing is a common daily activity aimed to maintaining the dental health. However, sometimes during the activity, there are some parts in the mouth that are difficult to be reached using a manual toothbrush. Therefore, now there is an innovations which are called as smart electric toothbrush. This type of toothbrush combine the electric toothbrush with wireless technology.
In this article we will discuss all about smart electric toothbrush and its DJID certification requirements in Indonesia.
What is smart electric toothbrush?
Nowadays, toothbrushes are available in various forms, including toothbrushes that use electricity, called electric toothbrush. This type of toothbrush works by moving and rotating the bristles automatically.
Starting from this electric toothbrush, it was then developed into a smart electric toothbrush that allows the electric toothbrush to be connected to an application on a smartphone using Bluetooth technology.
How smart electric toothbrush works?
Smart electric toothbrush operates by utilizing Bluetooth radio waves. This type of toothbrush can help users clean their teeth more effectively and informatively.
Smart electric toothbrush can be connected to an application on a smartphone via Bluetooth. When the user starts brushing their teeth, the application will show how long the tooth brushing should be and provide guidance on which parts of the mouth that need to be brushed.
In addition, smart electric toothbrush can also provide a variety of information for their users. This toothbrush will send data to a smartphone application, including a history of the user’s brushing habits, tips for tooth brushing, and even a timer to ensure that the user brushes their teeth for two minutes.
Smart electric toothbrush can also send data to play music while the users are brushing their teeth so that they do not get bored.
Difference between manual and smart electric toothbrush
Both manual and smart toothbrushes work to clean teeth. However, it is important to know the differences between these two types of toothbrushes.
Manual toothbrush
Manual toothbrushes are quite effective in cleaning teeth. In addition, this toothbrush also has several advantages such as:
- Easily available, whether in pharmacies, small stores, or supermarkets
- More practical and does not require batteries
- The price is relatively cheap
- Available in many shapes and bristle choices
Despite its advantages, manual toothbrushes also have disadvantages. When using this type of toothbrush, people tend to brush their teeth too hard, which can damage their teeth and injure their gums.
Smart electric toothbrush
Several studies have shown that smart electric toothbrushes are more effective at cleaning teeth than manual toothbrushes, some of the advantages are:
- Cleans teeth better than a manual toothbrush
- Smart timer of 2 minutes brushing will help users to ensure the ideal brushing time
- Has a pressure sensor feature that can detect when teeth are brushed too hard
- Supported by Bluetooth technology to ensure water resistance
- Equipped with a battery indicator to help users know the battery status
Some of the disadvantages of smart electric toothbrush including:
- The price is quite expensive and not available everywhere, especially in areas far from big cities
- It is quite impractical to use when traveling because you need to bring a spare brush head
- The waste contains batteries and electricity so it is less environmentally friendly
- Not everyone is comfortable with the vibrations it causes
DJID certification for smart electric toothbrush
As previously mentioned, smart electric toothbrush operates with Bluetooth connectivity. The use of Bluetooth technology requires every smart electric toothbrush to meet the applicable Bluetooth technical standards in Indonesia.
The fulfillment of these technical requirements are carried out through a product certification process, called DJID certification. Therefore, it is important for Indonesian distributors of smart electric toothbrush to carry out DJID certification before marketing the products in Indonesia.
Before submitting application of DJID certification, Indonesian distributors need to complete the RF and EMC test first.
RF testing
Bluetooth testing needs to be done before applying for DJID certification. The testing parameters for Bluetooth will refer to the technical regulations of KEPMEN KOMINFO No 260 year 2024. Below are the testing parameters for Bluetooth.
| Frequency band | Output power | Spurious emission | Testing method |
| 2400 – 2483.5 MHz | < 20 dBm EIRP | EN 300 328 | EN 300 328 |
The required testing sample to perform a Bluetooth test is one conducted sample. During the Bluetooth testing, the sample will be transmitted on the low and high channel with continuous and modulation waves.
EMC testing
Since smart electric toothbrush generally use batteries as their power supply, then the EMC testing parameters that need to be done are usually only radiated emission.
Smart electric toothbrush must pass the EMC radiated emission test in the frequency of 30 MHz – 1 GHz and 1 – 6 GHz. The EMC testing is performed based on the international standard of CISPR 32.
