Description
Technical Field
The invention relates to the field of oral health care, in particular to a novel toothbrush which is provided with a pressure sensor and can correct tooth brushing angles and postures.
Background
Caries and periodontal disease are two major diseases that are detrimental to oral health, the presence of plaque being the major cause. Brushing is an important self-oral care method to remove plaque, soft scale and food debris, keeping the mouth clean. Factors influencing the brushing effect include the type of toothbrush, the type of toothpaste, the brushing method, the brushing frequency, the brushing time, etc. It has been found that although most people are educated from oral care and develop good oral care habits, knowledge about the correct brushing regimen is not deep enough to make the caries rate and periodontal status of the population optimistic. Therefore, the popularity of a proper and effective brushing regimen is essential.
Common brushing methods are Papanicolaou brushing, modified Papanicolaou brushing, circular brushing and transverse brushing. Papanicolaou brushing, also known as horizontal vibration, is a method that is effective in removing plaque and food debris from the gingival sulcus. The improved Papanicolaou brushing method is also called a horizontal vibration brushing method, and is characterized in that brushing action from a gingival part to a coronal part is increased before each step is finished on the basis of the Papanicolaou brushing method, so that the cleaning efficiency of the Papanicolaou brushing method is improved. The research shows that the oral health state of children, adults and orthodontic patients is obviously improved by using the Papanicolaou brushing method and/or the improved Papanicolaou brushing method, so the Papanicolaou brushing method is considered to be a scientific and effective oral health method, and is worthy of being widely popularized in community and children oral health.
Common methods for popularizing the Papanicolaou brushing method at present include oral declaration, picture and text, multimedia teaching, model demonstration and the like. Investigation and research show that the influence of the conventional public oral hygiene propaganda on the correct tooth brushing behavior is limited; in traditional oral health education, a subject gradually forgets learned knowledge after receiving health education for a period of time and reverts to previous behavioral habits. Multimedia teaching and model demonstration can correct the incorrect brushing method of the subject to a certain extent, thereby improving the oral health state of the subject. Researchers at home and abroad also design mobile phone monitoring software and mobile phone videos to assist a subject to learn the Papanicolaou brushing method by themselves, so that learning efficiency is improved to a certain extent, and the duration of a correct brushing method is prolonged. The model demonstration method applied at present is to apply a common dentition model, carry out the teaching of the Papanicolaou brushing method step on the subjects by the oral professional or the person trained by the oral professional knowledge, correct the brushing mode of the subjects in a short period and improve the oral cleaning degree of the subjects. However, the lack of a marker on the dentition model is unfavorable for the subjects to repeatedly learn the method alone, and long-term effects are not optimistic enough with the recovery of the subjects' brushing methods and behaviors. Furthermore, the model demonstration method has extremely limited benefit and is generally lacking in middle and primary school units.
Therefore, it is necessary to develop interactive, participatory oral hygiene guidelines and design a toothbrush that can effectively supervise and correct a person's brushing method for a long period of time. Therefore, the novel scientific and efficient toothbrush with the sensor provides great convenience for popularizing and popularizing oral hygiene guidance of the Papanic brushing method, and can be popularized and alive and has a corrective action on daily brushing of people so as to ensure long-term habit formation.
