Comparison Oral-B Pro 2500 Cross Action vs Oral-B Pro 570 Cross Action

The number of working nozzles that are standardly supplied with the device. Nowadays, options are quite common with both one and two or three nozzles in the kit; and in the most extensive sets, this number can be four or five or even more.

In many sets, several nozzles may have different purposes. For instance, an irrigator, in addition to its standard nozzle, might include orthodontic and periodontal nozzles. However, it's important to note that models with the same number of accessories in the kit can have different specific specializations. So, when making a choice, it's wise to consider not just the quantity but also the types of nozzles available. Additionally, there's an option where several identical interchangeable heads come with one handle. This configuration is particularly common in toothbrushes. It enables multiple individuals, such as family members, to use a single device, and such a set is usually more cost-effective than purchasing individual toothbrushes for each person.

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.
