Comparison B.Well WI-922 vs Revyline RL 500

The number of operating modes provided in the device. For flossing systems (see "Type"), this paragraph takes into account the characteristics of the irrigator; data on the toothbrush (if they differ) are indicated in the note.

The mode in this case means the general format of operation, as explained in more detail in the "Modes" section below. It's important not to confuse this parameter with the number of power settings, which are discussed separately in the "Power modes" section. These characteristics are generally distinct from each other. For instance, a toothbrush with one operating mode may have multiple power settings, and conversely, there can be just one power level with several operating formats.

Anyway, the presence of several modes significantly expands the functionality of the brush/irrigator, allowing the device to be used for different procedures (or for several users with different needs in terms of oral hygiene). The flip side of this versatility is the increased cost. In addition, note that with the same number of modes, a specific set of these modes in different models may be different; so before buying, be sure to clarify how the capabilities of the selected model meet your requirements.

It's important to distinguish between the number of power settings and the number of operating modes, as these are distinct parameters. Refer to the "Operating modes" section for details on the various modes. In this context, we emphasize that power adjustment, if available, may not be accessible in all modes. For example, in an irrigator offering two modes of operation—continuous jet and pulsation—power adjustment might only be available in the continuous jet mode.

Having multiple power settings enhances the versatility of the device. Even if a device technically offers only one operating mode, the ability to adjust the intensity of the treatment allows users to tailor the device for various tasks. For instance, in many toothbrushes, the traditional 2D brushing mode at its lowest power setting effectively serves as a gentle treatment option. However, it's worth noting that the capability to adjust power levels can somewhat increase the device's cost.

The pressure of the water supplied by the irrigator (see "Type") to the operating nozzle. Usually, this pressure can be adjusted within a certain range, since different situations and purposes require different processing intensity. The wider this range, the more versatile the device.

The lower limit of the pressure range in modern irrigators is around 30 kPa; similar values are set for procedures for sensitive teeth, for certain gum diseases and in other cases where the most gentle treatment is required. 400 – 500 kPa is considered an average level, and 600 – 650 kPa is considered high, such indicators allow for deep cleaning (see "Functions"). And higher values are rare, and they are used mainly when cleaning the tongue. However, it is best to consult with a dentist before purchasing an irrigator and choose a model for working pressure based on the recommendations received.

This parameter represents the highest pulsation frequency achievable by the device. It's specified for brushes that support pulsating cleaning technology (as explained above), as well as for irrigators equipped with a jet pulsation mode. In the case of flossing systems (as mentioned in the "Type" section), this section typically provides information about the irrigator's pulsation frequency, and details about the toothbrush's pulsation frequency (if applicable) are mentioned separately in a note to this paragraph.

The high frequency of pulsation (40 000/min and more) in toothbrushes provides high efficiency, allowing you to quickly and efficiently deal with dense plaque and even tartar. On the other hand, too intensive processing is also undesirable — for example, with high sensitivity of the teeth. All this is also true for irrigators — except that the operating frequencies in them are noticeably lower, such devices rarely produce more than 2K pulsations per minute.

In view of all this, it does not always make sense to chase the maximum frequency of pulsations — it is worth considering the individual characteristics of the user. And ideally, before choosing a brush or irrigator with pulsation, you should consult a dentist; this will not hurt even with healthy teeth, and even with problems with teeth or gums, it is highly recommended.

Additional items supplied with the device (in addition to the base and attachment set).

The most popular types of such items nowadays are charging stand, accessory stand, UV sanitizer and case ; Here is a more detailed description of each option:

— Charging stand. A battery charging device designed as a stand serves the dual purpose of recharging the battery and offering added convenience for storing the device. It's worth noting that this function can apply to dental centers, even if they primarily operate on mains power (as indicated in the "Type of power" section). In such cases, the toothbrush included with the dental center typically runs on batteries, and the charging stand is typically integrated directly into the main unit of the dental center for ease of use.

— Stand for accessories. A device designed to hold various accessories, primarily interchangeable nozzles, can come in different designs. For example, in toothbrushes and portable irrigators, this device is often integrated into a charging stand, which includes both a charging socket and open compartments for accessories. In irrigators and fixed-layout dental centers, these compartments are usually built into the main unit or the lid of the water tank. In this case, the compartments are typically covered with lids for hygiene reasons, making it...a more hygienic option. Regardless of the design, having a dedicated stand for accessories enhances the convenience of storing them.

— UV sanitizer. A device that uses ultraviolet (UV) radiation for disinfecting the device, particularly replaceable nozzles, is typically designed as a distinctive container. In some models, this container also serves as a cover or case. The disinfection process effectively eliminates the majority of pathogenic bacteria and viruses, all without the need for additional chemicals and ensuring safety as the radiation remains confined within the container. However, it's important to note that UV disinfection is not effective against regular dirt and debris, so having this function doesn't eliminate the need to clean the nozzle through washing.

— Case / cover. The device comes with a storage and carrying container, which can be either a hard case or a soft cover. Hard cases offer better protection, while soft covers are more compact and can be rolled up when not in use. Regardless, both of these accessories are highly convenient for storage and transportation. They safeguard the contents from dirt and damage, and in many cases, provide space to store additional accessories, reducing the risk of losing them. While you could use makeshift packaging for the same purpose, the provided container is typically more practical.
