Comparison Oral-B Kids Power Toothbrush D10.513 vs Oral-B Stages Power DB-4

The frequency of working movements of a toothbrush with a reciprocating-rotating or reciprocating-brushing brushing technology (see above). In modern models, this figure can be from 4 – 5 to 40K movements per minute.

The higher the speed of the toorhbrush, the faster and more efficiently it handles with its task. On the other hand, high speed and intensity of processing is not always desirable — for example, with sensitive teeth or weak gums, such a brush can create problems. Therefore, you need to choose a device according to the frequency of rotation, taking into account the characteristics of your teeth; Ideally, you should consult with your dentist first. However, modern toothbrushes may have several modes, including gentle (see "Functions").

The presence of a nozzle wear indicator in the design of the device.

This function is primarily relevant for toothbrushes, including complete dental center brushes (as mentioned in the "Type" section). It pertains to the brush nozzles with bristles, which are prone to wear and require regular replacement to maintain their effectiveness. Neglecting to replace worn-out nozzles can even pose risks to dental health. The implementation of this indicator can vary. In some models, it's integrated directly into the nozzle, often taking the form of bristles with a special color. When these bristles lose their color, it serves as a signal that it's time to replace the nozzle. Other devices, especially those synchronized with a smartphone (as discussed below), may offer more advanced indicators. These can include a timer that monitors the depletion of the nozzle's resource or a sensor that detects critical wear by analyzing changes in the nozzle's vibration pattern. In any case, this feature makes it easy to monitor the condition of the working part and reduces the risk of missing the moment when it should be replaced.

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.

The type of power used by the device.

Battery powered is the most popular nowadays — it is provided in most toothbrushes, as well as many irrigators and portable flossing systems. Battery power is much less common, and the mains connection is used by powerful irrigators and flossing systems designed for stationary use. Here is a more detailed description of each of these types of power:

— Battery. Battery-powered devices have a built-in, usually non-removable battery that allows them to function without being constantly plugged into an outlet. These batteries are advantageous for several reasons. They are compact, lightweight, and provide longer usage time. Additionally, batteries are typically included with the device, saving you the expense of buying separate power sources. Some models even come partially charged, ready to use right out of the box. Maintenance costs for battery-powered devices are minimal since you only need to recharge the battery when it's depleted, eliminating the need for battery replacements. However, it's important to note that replacing a dead battery with a fresh one is not as quick and easy as with disposable batteries. In the case of items like toothbrushes and irrigators, this inconvenience is often not a significant issue. These devices can be conveniently charged on a stand connected to a standard outlet, and the chargin...g time is relatively short. While battery-powered models may be slightly more expensive initially, their added features and convenience often justify the higher price in the long run.

— Batteries. Devices powered by replaceable standard-sized batteries, such as AA, are generally more affordable than rechargeable ones. However, this cost advantage is because the batteries are usually not included, requiring separate purchase. While this incurs additional expenses, it grants users the flexibility to choose their preferred type of battery. In the case of toothbrushes and similar devices, there's a choice between disposable and rechargeable batteries in the appropriate size. One clear advantage of replaceable batteries over built-in ones is the ability to quickly swap them out. This minimizes interruptions for charging and even allows the device to function without needing a power outlet, as long as you have a supply of batteries on hand. However, this feature is often not essential, and replaceable batteries of similar size typically have lower capacity and may require more frequent replacement or recharging. As a result, this power source is primarily found in inexpensive toothbrushes, where it helps keep costs down.

— Mains. Some devices are powered by a standard household outlet, which is suitable for high-performance equipment and offers uninterrupted operation. However, the downside is that these devices are stationary due to their need to be connected to a power source. You'll typically find this type of power source in flossing systems and irrigators designed for permanent installation rather than on-the-go use. These devices typically consist of a central unit with a built-in water tank. The irrigator handle, equipped with a nozzle, connects to this unit via a hose. In flossing systems, there is also a socket for a toothbrush (usually battery-powered, as mentioned earlier). In addition to the advantage of unlimited operating time, these devices have much larger water tank capacities, usually starting at 400 ml and sometimes exceeding 1.5 L in certain models.

This refers to the maximum duration a device can run continuously when powered by a fully charged battery or fresh batteries. It's worth noting that this metric may also apply to models designed for mains power, such as flossing systems that include rechargeable toothbrushes, in which case we're referring to the battery life of these toothbrushes.

It's important to note that device specifications typically indicate the maximum runtime under ideal conditions, often in the most energy-efficient mode of operation (and for models with replaceable batteries, using high-quality batteries). The actual battery life can vary depending on specific usage conditions. However, this parameter still serves as a valuable basis for comparing different models. Generally, differences in the claimed operating time correspond proportionally to the real differences in battery life. For example, if one toothbrush has a stated operating time of 20 minutes and another boasts 40 minutes, in practice, their battery life (under similar conditions) will likely differ by approximately two times.

It's important to consider that, for toothbrushes, this parameter can help estimate the number of brushing sessions you can expect on a single charge. Typically, the recommended daily brushing duration is 2 minutes. So, if a toothbrush has an operating time of 30 minutes, it's sufficient for approximately 15 cleaning sessions (or more realistically, around 14 or 13).

The time required to charge the battery from zero to 100% in a device with the appropriate power type (see above). This parameter can vary from 1 – 3 hours in relatively simple and low-power devices to a day in advanced models with capacious batteries. At the same time, the longer the maximum operating time on a charge (see above), the longer, usually, the time required for charging, although there is no hard dependence here.

In general, having fast charging capabilities improves the convenience of a device by reducing interruptions in its operation. However, there is a trade-off to consider: fast charging often means either a smaller battery capacity or a higher price due to the use of specialized technologies to speed up the charging process. When evaluating this parameter, it's essential to think about how you intend to use the device. For instance, if a toothbrush or irrigator is solely used at home by one person and comes with a charging stand, fast charging may not be a critical factor. The device remains consistently charged as it's constantly on the charger, and its battery doesn't deplete significantly during one use. The time between sessions, usually around 8 to 12 hours, is more than enough to maintain a charged battery, even for devices with slower charging. However, if you plan to use the device while traveling, where access to power outlets is sporadic, it's preferable to have minima...l charging time to ensure you can recharge quickly during your 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.

The total weight of the device is an important consideration. In the case of stationary irrigators and dental centers (as mentioned in the "Type" section), weight isn't a significant factor since the main unit is placed on a stand or wall, and you don't have to hold it. In fact, for some of these models, weight may not even be specified. However, when it comes to toothbrushes or portable irrigators, the device's weight becomes a crucial factor. A heavy device can strain your hand and make it challenging to use during teeth brushing or other procedures. It's generally recommended that the weight of a portable device should not exceed 200 g, and lighter is often better. It's worth noting that in models that come with stands (as discussed earlier), the total weight is typically provided, accounting for both the main unit and the stand. The weight of the main unit alone is usually around 1.5 to 2 times less than the total weight.
