Compositions for use in dentistry and related devices for treatment of the oral cavity

Abstract

A composition (C) for use in dentistry and a device (1) for treating the oral cavity, the device comprising: a housing chamber (2) containing the composition (C) in liquid state; a conduit (3) comprising For discharging a composition (C) configured to generate a flow (F) at a given discharge pressure; and a delivery valve (4) interposed between the holding chamber (2) and the discharge conduit (3) During the period, the valve (4) can be switched between a delivery state and a closed state. In the delivery state, the accommodating chamber (2) is fluidly connected with the conduit (3) to allow a predetermined amount of the composition (C) to pass through. In the closed state , the composition (C) is not allowed to pass between the holding chamber (2) and said duct (3). The composition comprises 10-15 wt% sodium bicarbonate and 100 wt% water.

Description

technical field [0001] The present invention relates to a composition for use in dentistry and to an oral treatment device. [0002] In particular, the invention relates to a device and a composition dispensed by the device, which device enables the treatment in the oral cavity and in particular enables oral cleaning, whitening and prevention of bacterial formation on the teeth and gums . Background technique [0003] It is well known to routinely perform oral cleaning procedures by using a manual or electric toothbrush to spread a semi-solid composition (usually toothpaste in paste form) suitable for cleaning the teeth and gums. [0004] Using such systems, the composition is spread on a toothbrush and the bristles are then rubbed over the teeth and portions of the gums to clean the tooth surfaces and gingival sulcus and keep the oral cavity clean. [0005] This rubbing action removes any remaining food particles, bacterial film and plaque to limit caries and tartar forma...

AI Technical Summary

Problems solved by technology

[0019] However, the systems used by dentists also have significant disadvantages, mainly related to the invasive nature of such systems, which must therefore be performed intraoperatively by professionals

[0020] This leads to important disadvantages in terms of cost per tooth whitening procedure, since this procedure cannot be performed autonomously and routinely

[0021] Finally, another significant disadvantage of devices capable of delivering whitening powder is that they require extensive maintenance operations to remove all accumulated powder

After a series of operating cycles, the powder tends to accumulate and deposit on the delivery pipes, thereby clogging the pipes and thus preventing the correct application of the powder
