According to the Daily Mail, 600 people took part in the study of Tel Aviv University in Israel. The researchers divided these 600 people into two categories, one is the commonly used smartphones that use most apps, and the other is the ordinary smartphones that use almost no apps. After comparing the sleep habits and patterns of the two groups, the researchers said that smart phones not only make people sleep less and grind their teeth more frequently, but also deepen the degree of mandibular pain.
Pessia, the author of this study? Friedman? Dr Rubin explained that people have been using smartphones, and they will check social software and other applications from time to time for fear of missing some information. This kind of psychology makes people more and more dependent on smart phones, and it also makes people feel pressure and anxiety. Excessive use of smart phones will also cause substantial harm to people's health. As mentioned above, grinding teeth, insomnia, jaw pain, etc. These are the hazards of smart phones to human health.
And smart phones may really damage people's teeth, because grinding teeth is harmful to teeth. First of all, grinding teeth is harmful to periodontal tissue. The biting force produced by molars is very large. When this occlusal force acts on periodontal tissue, periodontal ligament will widen and thicken, alveolar bone hyperplasia and so on. In severe cases, tooth wear, occlusal trauma, periodontal disease and so on will occur.
Not only that, molars also have effects on teeth and pulp tissue. The most direct influence of molars is the loss of tooth tissue and the destruction of tooth shape. When the edges of teeth are sharp, they often stab the soft tissues of lips, cheeks and tongue. The loss of tooth tissue and the destruction of tooth shape will also change the face shape, that is, 1/3 under the face will become shorter and the face will become older. Such changes will affect people's beauty and pronunciation. So the use of smart phones needs to be moderate!
