1. Open your mouth as wide as possible, make a mouth shape when you shout "ah", keep this action for about 10 minutes, then close your mouth and relax your facial muscles. Repeat this for 3 ~ 6 times. This action can exercise the muscles of the cheeks and chin.

2. Gently pout your lips like whistling, slowly blow to make your cheeks swell, and keep this action for 5 seconds. Then relax the facial muscles, which can be repeated 3 times. This action can exercise the muscles of the cheek and enhance the elasticity of the cheek skin.

Clinically related diseases

1, malocclusion often makes the tension of masticatory muscles in an unbalanced state for a long time, which makes the condyle work in different States for a long time, thus causing the movement of masticatory muscles to be uncoordinated, the mandibular position to move and the condyle position to change, resulting in inconsistent joint pressure. On the high pressure side, the condyle moved backward and repeatedly hit the posterior region of the articular disc, resulting in injury of the posterior region.

2. The results showed that there was no significant difference in the changes of masticatory muscle potential in each group at rest. During mastication, the masseter potential of Angle Class Ⅲ malocclusion group was significantly higher than that of normal control group, Angle Class Ⅰ malocclusion group and Angle Class Ⅱ malocclusion group, and the difference was significant.

3. This shows that the muscle tension of maxillary muscle in Angle Ⅲ malocclusion patients is significantly higher than that in other malocclusion patients. When swallowing, the masseter potential of Angle Class Ⅱ malocclusion group was significantly higher than that of normal control group, and the difference was significant. The masseter potential of Angle Class Ⅲ malocclusion group was also higher than that of normal control group and Angle Class Ⅰ malocclusion group, and the difference was significant. Compared with the other three groups, the digastric potential of Angle Ⅲ malocclusion group was lower than that of the other three groups, with significant difference.

4. Related research shows that chewing betel nut often increases the possibility of oral mucosal lesions, among which oral mucosal leukoplakia and oral mucosal erythema are common oral precancerous lesions, which increase the incidence of oral cancer. There are three main reasons:

(1) Physical injury. Chewing betel nut, in which the fiber friction will cause oral mucosal damage, such as long-term chewing will also lead to the injury is difficult to heal, forming chronic damage, causing chronic inflammation and other diseases.

(2) Biological toxicity. Arecoline is the main component of areca catechu. Studies have shown that arecoline can obviously promote epithelial cell apoptosis and interfere with the precipitation and degradation of extracellular matrix macromolecules (collagen, elastin, etc.). ). At present, betel nut chewing in China is mainly processed by shepherd's purse and lime, and nitrosamines, clove polyphenols and active oxidants contained in them may also produce certain toxicity.

(3) Used with tobacco. Using betel nut chewing tablets together with tobacco can promote the occurrence of oral cancer more than chewing betel nut alone. This is mainly because smoking itself is an independent risk factor for oral cancer. Chewing betel nut containing tobacco will obviously increase the toxic substances in saliva and obviously destroy the process of DNA synthesis in cells.
