How can people look after their oral healthcare during summer?
(02.21.2008)

1. Be careful of cool temperatures

In summer, doctors often see such patients: they are normal before going to sleep, but when they awake, they suddenly find they cannot drink water or wash their mouth out; they suffer from facial distortions, leak water from the mouth when drinking, have an inability to inflate the cheeks with air, leak air when blowing out, their forehead wrinkles disappear, they have an inability to frown, suffer hypophasis and conjunctiva, etc. This disease is called Bell Paralysis, and is a simple type of paralysis of the peripheral facial nerves. Bell Paralysis usually occurs after a local region of the body is blown on or exposed to a cold temperature by cold wind; it is probably caused by a spasm of blood vessels supplying the facial nerves, thus the nerves suffer from ischemia and injury, followed by edema (swelling) of the tissues. Edema aggravates the oppression of the nerves and hinders the flow of lymph and blood, so the vicious cycle results in facial paralysis. Therefore, in order to prevent Bell Paralysis, avoid suffering from a chilling of the face, especially in the retroauricular region, and do not sleep near open windows or on the roof at night; moreover, avoid the retroauricular region being chilled by the cold wind when riding.

2. Keep good oral health habits and avoid suffering from foul breath

Foul breath often greatly worries many patients. It may affect interpersonal communication severely and have a negative impact on the patient. As a disease, foul breath is receiving increasing attention from a growing number of stomatologic doctors and is getting extensive care from people. About 85 to 90% of foul breath comes from the mouth; bad oral health, thick lingual fur, decayed teeth, peridentitis, food residues, impurities in artificial teeth or smoking may all cause foul breath. In addition, rhinitis, nasosinusitis, gastritis, gastric ulcers, diabetes mellitus, liver dysfunction or uremia are also associated with foul breath. Due to the heat in summer, people may suffer from insufficient sleep, mental stress, and overtiredness, and these may lead to temporary physiological foul breath. Good oral habits may cure most cases of foul breath; cleaning the back of the tongue, tooth brushing and rinsing the mouth are all effective methods. When a patient suffers from chronic refractory foul breath, he/she should be examined to see whether he/she has other diseases.

3. Prevent children from tooth trauma in summer

Children belong to a special group of oral patients. With the arrival of summer, some oral diseases suffered only by children show a trend of high incidence. In summer, a decrease of immunity caused by a lack of temperance in eating and drinking, excessive amusement and an irregular lifestyle may lead to many kinds of oral disease, for example, decayed teeth, endodontitis, periapical periodontitis and so on. Children are lively and active and they have no supervising teachers during the summer holidays, so the morbidity of tooth trauma increases greatly. After a tooth trauma, a child should see a stomatologic doctor in a normal hospital. The doctor will give the child corresponding treatment according to their condition. If a damaged tooth is loosened obviously, it should be fixed with epithesis to accelerate its recovery. If a child suffers from the complete dislocation of a tooth, the tooth should immediately be put in a cup that contains physiological saline, milk or tap water, or stored sublingually or in the oral vestibule of the child, and a doctor should be seen without delay. To greatly increase the survival rate of re-implanting the tooth, one should definitely avoid storing the tooth in a dry state. Generally, regular returns to hospital are needed after a tooth trauma in order to observe the survival and therapeutic effect of the dental nerve.
