Comparison Oral-B Pro 400 Junior vs Oral-B Vitality Sensitive D12.513S

Devices intended for use by children. Such models are created taking into account the fact that a child's teeth require a softer treatment than in the case of an adult; in addition, children's toothbrushes usually have a bright design that is attractive to children and smaller brush heads.

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.

Modes of operation supported by the device.

Toothbrushes nowadays offer a wide range of modes beyond the traditional daily cleaning (often referred to as "2D" mode). You can find toothbrushes with options like the advanced 3D mode, as well as programs for gentle and deep cleaning, polishing, whitening, gum massage and tongue cleaning. On the other hand, irrigators typically offer different modes in addition to the standard continuous water jet. These additional modes often include pulsation and spray options.

Here is a detailed description of the most popular options found in brushes:

— Daily cleaning (2D). The "2D" mode of operation in toothbrushes closely resembles the traditional manual toothbrush experience. In this mode, the bristles of the brush move in a single plane, and the exact movement pattern may vary depending on the cleaning technology used. The intensity of brushing is typically medium to high, making it suitable for individuals with relatively healthy and not overly sensitive teeth. The recommended daily brushing time is 2 minutes, with 30 seconds allocated to each quadrant of the mouth. These corresponding settings are usually available in the timer function, if the toothbrush is equipped...with one. While "2D" brushing is somewhat less effective than "3D" (as mentioned below), it's a feature that can even be found in more affordable toothbrush models.

— Daily cleaning (3D). This feature, available in brushes with reciprocating-rotating and reciprocating-sweeping technology, involves bristle pulsation in addition to the standard cleaning motion. The pulsating movement, which goes deep into the brush head and back, enables cleaning in three dimensions simultaneously. This greatly enhances efficiency compared to the 2D cleaning mentioned earlier. These bristles not only address the outer tooth surfaces but also reach the sides and interdental spaces to some extent (though it's not a complete replacement for dental floss). However, it's worth noting that this advanced functionality typically comes at a higher cost.

— Gentle cleaning. The gentle treatment program, typically used for sensitive teeth and gums prone to bleeding, is common in brushes with reciprocating-rotating and reciprocating-brushing technologies. In these brushes, the gentle mode often involves reducing the nozzle's rotation or vibration speed. In sonic and ultrasonic models, gentler treatment is achieved by reducing vibration intensity. Regardless of the technology, this mode aims to minimize discomfort during brushing and the risk of gum damage, even when using standard nozzles. For the gentlest effect, it's advisable to use this function with a nozzle designed for sensitive teeth.

— Deep cleaning. Most often, this name means cleaning with a standard intensity, but an increased duration — for example, 3 minutes instead of the usual 2 minutes (45 seconds for each quadrant of the mouth instead of the traditional 30 seconds). This mode allows you to effectively clean your teeth and remove dirt, for which normal daily brushing is not enough.

— Polishing. A mode for treating relatively clean teeth that do not require a full-length cleaning. Usually, polishing is carried out at a reduced frequency of vibrations (rotations) and takes noticeably less time than conventional processing (for example, 1 minute instead of the traditional 2 minutes).

— Whitening. A special mode for whitening tooth enamel and removing stains, especially from the front teeth, is often an extended version of the regular brushing mode. For example, in a whitening mode, the brush might operate normally for 2 minutes and then switch to increased intensity for 30 seconds. Specific details about this mode, including any contraindications (especially for individuals with sensitive teeth or gum issues), should be checked separately.

— Massage gums. Gum treatment can be offered either as a separate program or as an add-on to the regular brushing routine. In the latter case, it typically involves a standard 2-minute toothbrushing program followed by activating an additional mode. This function not only ensures effective cleaning but also contributes to gum strengthening. It can be beneficial for addressing issues like inflammation and bleeding gums, although consulting a dentist is advisable in such cases.

— Cleaning the tongue. A separate mode for tongue cleaning is available in many electric toothbrushes. Brushing the tongue with an electric toothbrush can often cause discomfort due to tickling, so this mode typically offers a brief cleaning session lasting about 20 seconds. If needed, you can perform multiple sessions. It's important to note that the presence of a tongue cleaning mode doesn't necessarily mean that a specialized nozzle for tongue cleaning is included in the kit (as discussed in the "Nozzles" section), although it's commonly included.

It should be noted that in some toothbrushes, the mode change is carried out due to “smart” nozzles: when such a nozzle is installed, the device recognizes it by the built-in chip and automatically switches to the appropriate programme.

In turn, in irrigators, the features of the main modes are as follows:

— Jet (monoflow). The classic, most popular working format: a constant jet with a constant pressure. Provides sufficient efficiency for most tasks for which irrigators are used, while being extremely simple to implement and can be provided even in the most inexpensive models.

— Pulsating. Water supply with variable pressure. This mode is especially effective for removing dirt from the interdental space, under braces and in other hard-to-reach places.

— Spray. In this mode, a mixture of water and air is fed through the nozzle, due to which, instead of the usual jet, a cloud of small droplets flying at high speed is obtained at the exit. This mode is great for massaging the gums and general cleaning of the mouth.

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 pressure sensor in the device — a sensor that monitors the force with which the working nozzle is pressed against the teeth/gums.

This feature is primarily found in toothbrushes, including those that are part of flossing system units (as discussed in the "Type" section), but it can also be included in irrigators. Its primary function is to prevent potential harm to the teeth and gums caused by excessive pressure during brushing. The sensor's response can vary from one device to another; some devices emit a warning signal, while others reduce the bristle movement speed, and some may even shut off entirely in response to excessive pressure.

Having a pressure sensor in such devices can be beneficial not only for individuals with healthy teeth but also for those with heightened sensitivity or gum issues. It's a highly desirable feature for maintaining oral health. However, it's important to note that in many models, the pressure sensor is not integrated into the main body of the device but is instead part of the replaceable nozzle. Additionally, not all complete nozzle options may have this function, so it's essential to verify these details separately when choosing a device.

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).

An indicator showing the battery charge level.

This function is predominantly found in battery-powered devices (as mentioned in the "Type of power" section). Implementing a charge indicator with replaceable batteries is challenging but occasionally seen. The specifics of this feature and how it operates can vary. The simplest form of a charge indicator is composed of LEDs. For instance, a green light might indicate a normal charge level, yellow signals a low charge, red signifies the need for charging, and blinking typically indicates that charging is in progress. More advanced indicators exist as well, such as those with their own displays that can show the specific charge level using a battery icon or even as a percentage. Regardless of the design, this feature simplifies monitoring battery status and reduces the risk of finding yourself with a dead battery at an inconvenient time.

The cable length for connecting the device to the power source is an important consideration. It's worth noting that this specification may also apply to battery-powered models (as mentioned in the "Type of power" section), where it refers to the cable for connecting the charger stand or the device itself to a power outlet.

Typically, shorter cable lengths (up to 1 m) are common for battery-powered models that don't require a direct connection to the power source for operation. Some of these models don't even include charging stands and are intended to be charged outside the bathroom. In contrast, longer cables are primarily found in devices powered by mains electricity designed for stationary use. In these devices, the power cord can be nearly 2 meters in length. This design allows for the cord to be extended outside the bathroom if needed because not all bathrooms have electrical sockets, and using extension cords in such humid environments is generally discouraged.

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.
