Comparison Panasonic EW-1611 vs Oral-B Professional Care MD20

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.

Models of replacement heads supplied with the device.

This information is valuable for assessing the capabilities of a specific model and for sourcing additional, spare, or replacement nozzles, particularly for toothbrushes and dental centers that naturally use such devices (as indicated in "Type"). Firstly, it's advisable to replace the heads in these devices every 3-6 months, similar to regular toothbrushes. Secondly, if each user purchases their own nozzle while sharing a single handle, it's a cost-effective alternative to buying a separate brush for each individual, although it may be less convenient. Regardless, knowing the model of the interchangeable nozzle will save you time and effort when searching for compatible accessories.

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.

The number of power 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.

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.

The brushing technology used by the toothbrush (see "Type").

In today's market, toothbrushes mainly feature cleaning technologies such as a href="/list/420/pr-14372/">reciprocating, reciprocating-sweeping, sonic and ultrasonic. The first two options can also include the additional feature of pulsating technology. The main difference between these methods lies in the nature of the movement of the bristles; Here is a more detailed description of each option:

— Reciprocating. This cleaning technology involves the bristles on brushes with round heads moving in a traditional manner. As the name suggests, the head rotates back and forth at a slight angle during operation. This technology is considered somewhat more advanced than reciprocating-sweeping, particularly because it offers improved cleaning in interdental and similar areas. However, it's important to note that brushes with this technology still don't match the efficiency of sonic and ultrasonic brushes but are generally more budget-friendly.

— Reciprocating-sweeping. Historically, this technology was the first to be used in brushes with oval nozzles. In brushes employing this principle, the bristles oscillate from left to right, resembling the motion of a broomstick—hence the name "reciprocating." Classic reciprocating brushes are characterized by a sim...ple design but are not particularly effective. Consequently, there are few such models available today, primarily found in low-cost devices. Most toothbrushes with oval heads now use more advanced sonic or ultrasonic technology.

— Pulsating. Usually, this term refers to the format of operating, in which the bristles move up and down relative to the surface of the nozzle, in other words, they go deep into the head and move back. This technology is rarely used in its pure form, it usually complements a reciprocating or reciprocating sweeping head, providing 3D cleaning capabilities (refer to "Modes"). But if the 3D mode is not claimed in the toothbrush, it is worth clarifying separately what is meant by pulsating technology. So, in some models, we are actually talking about the whitening mode, when, for maximum intensity of exposure, the device does not work constantly, but in separate pulses; in others, the term "pulsating" actually refers to the sonic or ultrasonic mode of operation.

— Sound. Sonic cleaning technology involves bristle vibrations with a small amplitude at a high frequency, reaching up to 40K vibrations per minute — this speed aligns with audible sound frequencies, hence the name "sonic." This cleaning method is considered more advanced than reciprocating and even reciprocating-sweeping technology. Sonic brushes, thanks to their high vibration speed, create a fine, uniform foam by mixing toothpaste, saliva, and air during cleaning. This foam can effectively penetrate hard-to-reach areas, and the vibrations themselves prove highly efficient at removing plaque, including from interdental spaces. While ultrasonic cleaning is considered even more advanced (as discussed below), sonic brushes are generally more affordable.

— Ultrasonic. Ultrasonic cleaning technology represents a further advancement of the sonic technology described earlier, distinguished primarily by a higher oscillation frequency. It's important to note that not all brushes in this category operate in the ultrasonic range; some models have oscillation frequencies that only slightly exceed 40K per minute, which is still within the range of audible sound. However, the operating frequency of such devices is significantly higher than that of standard sound devices. Ultrasonic technology offers several advantages, including thorough cleaning with access to hard-to-reach areas and a bactericidal effect. Ultrasound is capable of destroying bacteria responsible for plaque formation. However, brushes with this technology tend to be somewhat more expensive than their sonic counterparts.
It's important to mention that ultrasound technology is not as effective as conventional sound vibrations for cleaning braces and similar structures. As a result, some devices in this category incorporate both ultrasonic and conventional sound vibrations to ensure thorough cleaning in all situations.

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.

Possibility of mounting the device on the wall.

The design of the mount for these devices depends on the device type (as mentioned earlier) and how it's typically used. In the case of most toothbrushes, which are typically self-powered, they come with a wall-mounted stand that also functions as a charger. Some irrigators and dental centers follow a similar setup, but many of these devices are designed for stationary use and have a larger main unit to which a handle with a nozzle attaches. In such models, the wall mount is designed to accommodate the entire main unit.

Wall installation offers a significant advantage by saving shelf space, which is particularly beneficial in tight spaces. However, this installation method entails additional preparatory work, which can be somewhat challenging. Furthermore, not all wall mounts facilitate easy removal and installation of the device, making it less suitable for situations where you frequently need to take the toothbrush or irrigator with you on trips.

General dimensions of the device. Most manufacturers report this data only for stationary devices — irrigators of the appropriate variety and dental centers (see "Type") — because it is believed that toothbrushes (even with stands) are not so large as to be inconvenient, and not so varied in size, to pay attention to this difference.

Note that the dimensions are usually given only for the main unit, without taking into account the tools installed on it; however, the size of these instruments, again, it is not large enough to cause serious inconvenience.
