Comparison Seago E2 vs Seago SG-507

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.

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.

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 presence of a timer in the design of the device. All types of dental hygiene appliances can be equipped with this function (see "Type").

The timer function counts down and provides alerts, often at specific intervals, to help users monitor the time spent on brushing their teeth and mouth. This ensures that the oral care routine is effective without unnecessary prolongation. The timer settings can vary depending on the selected brushing program (as discussed in the "Modes" section). Following the standard recommendations of dentists, a typical daily brushing session should last at least 2 minutes, with 30 seconds allocated for each quadrant of the teeth. Consequently, when using this mode, the timer typically counts down from 2 minutes and signals every 30 seconds to prompt the user to move the brush to another section of the mouth.

The timer function can vary in its operation, depending on the specific model of the toothbrush or irrigator. The simplest approach involves fixed time settings for each mode, accompanied by audible and/or visual signals. Models equipped with smartphone synchronization (as discussed in the "Synchronization with a smartphone" section) often display timer data on the smartphone screen and allow users to customize the countdown duration to their preferences. In some children's brushes (as mentioned earlier), a musical timer is used, where the countdown continues until a melody finishes playin...g. There are also other unique features related to this function. Regardless of the specific implementation, the timer simplifies the use of the toothbrush or irrigator, eliminating the need for users to manually track the time themselves.

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.

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.

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 ability to charge the battery in the device from a standard USB port.

Refer to the "Type of power" section for battery details. Charging via USB offers several advantages over traditional mains charging. The primary benefit is the widespread availability of USB ports in computers, laptops, tablets, and various electronic devices. USB connectors are standard outputs in portable power banks, and USB adapters can convert 230V socket and car cigarette lighter socket outputs. This power source allows you to charge your toothbrush or irrigator not only from mains power but also from various other sources, even when sockets are unavailable, such as from a laptop or a power bank. This is particularly convenient during travel.

Another notable aspect of this charging method is that it often eliminates the need for a dedicated charger. All you need is a basic cable to connect the toothbrush or irrigator to a USB port. Typically, such a cable is included with the device, and the device itself features a standard microUSB port for power connection. This flexibility allows you to use alternative cables if needed, which are compatible with the plug type, making it more convenient and adaptable.

However, it's important to mention that these standard sockets on the device are not well-suited for use with charging stands, as discussed in the "Additionally in the kit" section. Consequently, some toothbrushes and irrigators...that use USB charging may not include charging stands at all, while others employ a unique design. In these cases, a dedicated socket for the charging stand is integrated into the device, and USB charging becomes accessible when the device is placed within a travel case, which also serves as a transitional component.

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.
