From the beginning, drugs and alcohol were part of society for medical and entertainment purposes. Alcohol existed as early as 10,000 BC. Other harmful medicines such as methamphetamine have spread in the past few decades. They have as much harmful and addictive prescription drugs as street drugs because they are taken over time like such Dirantin. This report details the long-term damage to drugs and alcohol abuse in the oral cavity in detail.
The mouth is essentially the same as the mouth, and the cavity consists of the cheeks, the soft palate and hard palate, and the lips as the vestibule of the mouth. The vestibule is between the gums and the cheeks. The oral opening is the oral cavity, generally called the oral cavity, and the oral cavity is the opening between the pharynx and the oral cavity. Oral cancer is the development of the oral mucosa or buccal mucosa, the tongue is the first two-thirds of the tongue, the tongue under the tongue is a hard palate, the upper part of the tooth is a triangle, the space behind the wisdom of the wisdom teeth. The tumor was found to be a malignant tumor. Uncontrolled proliferation of cells leads to the development of oral cancer and throat cancer. The most common cancer found in the mouth is squamous cell carcinoma
The use of tobacco is the main cause of oral cancer. The exposure-response relationship between the amount of tobacco consumed and the risk of oral cancer has been determined taking into consideration the effect of alcohol intake. Mortality due to oral cancer in the United States in 1985 is estimated to account for 92% of men and 61% of women (USDHHS 1990, p. 147). Oral cancer and pharyngeal cancer are predominantly epithelial cells, and about 90% are classified as squamous cell carcinomas (Silverman 1998). Most oral cancers have preceded the onset of precancerous lesions and dysplasia, as normal mucosa is transformed into intraepithelial carcinoma and eventually into invasive carcinoma.
