Comparison Oral-B Pro 760 Cross Action vs Oral-B Pro 790 Cross Action

General device type. In addition to classic toothbrushes (including those sold in the form of sets), nowadays you can find hygienic mouthwash devices — irrigators — as well as multifunctional flossing systems that combine the capabilities of a brush and an irrigator. Here are the features of each of these options:

— Toothbrush. These devices are designed for traditional toothbrushing using special bristles, essentially serving as electric versions of manual toothbrushes. While various models can differ significantly in terms of bristle movement (for more details, see "Cleaning Technology"), they share several common features. On the positive side, they are highly effective at cleaning the visible surfaces of teeth, surpassing irrigators in this regard. Some models are even capable of removing dense plaque and tartar with ease. Additionally, brushes are incredibly user-friendly and familiar to most people. However, they have limitations when it comes to cleaning the interdental spaces, even with specialized nozzles. To achieve the highest quality teeth cleaning, it's often necessary to use these devices in combination with an irrigator and/or dental floss. It's also worth noting that brushes with overly hard bristles or intense brushing can potentially damage the gums, particularly if they are already sensitive or inflamed. While the likelihood of such issues is re...latively low, it is higher compared to using irrigators.

— Set of toothbrushes 2 pcs. A set typically consists of two electric toothbrushes, which are often identical in terms of their characteristics (though exceptions exist). For detailed information about the toothbrushes themselves, please refer to the previous sections. Such a set can be particularly convenient for couples or households, and some options even offer brushes in "male" and "female" colors, like black and pink. Purchasing this set is not only more convenient than buying the brushes separately, but it is often more cost-effective as well, especially since there is usually only one charger included for the pair of brushes.
As for sets with unequal toothbrushes, they may include, for example, models with different types of nozzles, or an adult and a children's toothbrush.

— Irrigator. Irrigators are devices that clean the teeth and oral cavity by directing a high-pressure jet of water. This procedure effectively removes debris, food particles, and massages the gums, promoting gum health and preventing various oral issues. Irrigators can access areas where regular toothbrushes may struggle, making them suitable for cleaning braces and providing intense yet safe gum massages compared to bristle-based brushing. However, irrigators may not clean the visible surfaces of teeth as effectively as toothbrushes. Therefore, it's recommended to use an irrigator after regular brushing. Brushing can tackle more persistent dirt, while the water jet can address hard-to-reach spots that bristles might miss. Nevertheless, the spaces between teeth still require dental floss for thorough cleaning.
Separately, we note that irrigators can be both portable and stationary. The second type is more bulky and not suitable for travel, but stationary devices are equipped with capacious water tanks, have an almost unlimited operating time (thanks to mains power) and, usually, are more powerful than portable solutions.

— Flossing system. lossing systems are versatile devices that combine the functions of both toothbrushes and irrigators, as discussed in previous sections. This combination is particularly convenient because toothbrushes and irrigators have slightly different purposes, and having both can be beneficial. However, flossing systems come in various designs. Some models feature a universal handle that can switch between brushing and irrigating, depending on the nozzle used. Another common configuration is a rechargeable toothbrush paired with a stationary irrigator that also serves as a stand and charger. Alternatively, some sets include two separate devices, each with its own independent power source. Specific details about the flossing system's design should be checked separately.
In general, flossing systems are quite expensive, but most often they are still cheaper than separately purchased toothbrush and irrigator with similar characteristics.

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.

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.
