Description

A device for instructing oral hygiene The invention relates to a device for instructing a user how to maintain oral hygiene, the device comprising a mirror and a frame, and the mirror is fixed to the frame.The invention applies to a device for instructing the user how to maintain oral hygiene, the device comprises a mirror and a frame, and the mirror is fixed to the frame.

BACKGROUND Oral diseases pose a major health burden for many countries and affect people throughout their lifetime, causing pain, discomfort, disfigurement and even death. Treatment for oral health conditions is expensive and usually not part of universal health coverage (UHC). In most high-income countries, dental treatment averages 5% of total health expenditure and 20% of out-of-pocket health expenditure. The — majority of oral health diseases such as dental caries and periodontitis are largely preventable and can be treated in their early stages. Reducing oral health conditions calls for a reform of oral health systems to shift the focus from invasive dental treatment to prevention and more minor treatment. It has been found that personal instructions significally improve this. The burden of oral diseases can be reduced — through instructions by addressing common risk factors. Oral self-care guidance is part of preventive work and includes patient motivation, teaching a healthy diet and lifestyle, analyzing one's own risks, and directing home care such as tooth brushing. It is a well-known fact that many people have improper habits when performing oral hygiene. This includes, for example, tooth brushing. Oral self-care guidance is given in the dental clinics, but there are not enough resources for adequate preventive work. Preventive work can often also be targeted at specific groups of patients. In order to effectively prevent oral diseases, preventive work should be increased and targeted to all patient groups. However, this is guite time-consuming and people o may not respond to the instructions. In order to transfer knowledge more effectively, O 25 it would be good to use self-learning as a form of teaching. S Interactive mirrors are known for projecting images onto the mirror surface. This - may be done during tooth brushing or similar oral hygiene processes. However, they E are mainly meant for entertainment purposes. Using a mirror for instructing is not N easy because one has to be quite close to the mirror and therefore the instructions O 30 projected onto the mirror may not be visible. Usually a dental hygienist has to stand S beside the person to be instructed, follow how he or she brushes his or her teeth N and give instructions based on on observations from the mirror.BACKGROUND Oral diseases pose a major health burden for many countries and affect people throughout their lifetime, causing pain, discomfort, disfigurement and even death.

Figure 1 shows an embodiment of a device 100 for instructing a user how to maintain oral hygiene. When the device is activated, it will perform an instruction session for the user. The device comprises a mirror 101, a frame 102, a processing unit, and a touchscreen display 103. The touchscreen display is behind the mirror. The mirror 101 is a vertically elongated structure. This means that the height of the mirror is greater than its width. This is the preferred shape, because the device 100 is meant for one user at a time. The mirror comprises a reflective part and a semi- reflective part 104. The touchscreen display 103 is at least partly behind the semi- reflective part. The semi-reflective part of the mirror is made such that it reflects light when the touchscreen display or some area of the touchscreen display is inactive, S i.e. the touchscreen display is not emitting light. The emitted light of the touchscreen N display is more intense than the reflection of the semi-reflective part, so the images ro 25 rendered on the touchscreen display are more prominent than the reflection. If the = intensity of the touchscreen display is reduced or the touchscreen display is turned I off, the reflection on the semi-reflective part can be seen again. The semi-reflective part of the mirror is positioned in such a way that when the user stands before the & device, the user's face is at the same level as the semi-reflective part of the mirror, S 30 i.e. the user's face is in front of the semi-reflective part. This means that the mirror S is positioned in such a way that the upper edge of the mirror is at least slightly above the average height of the users.DETAILED DESCRIPTIONS OF THE FIGURES 5 The embodiments in the following description are given as examples only and someone skilled in the art can carry out the basic idea of the invention also in some other way than what is described in the description.
