1, dental cosmetic methods
Method one: porcelain teeth
The metal porcelain crown in dental plastic surgery is made of metal with an inner crown, and then fused porcelain on the surface of the inner crown on the high temperature to form a crown with the same color as the natural teeth, good color, realistic appearance. Porcelain crown technology was successfully developed by the United States in 1950, and its technology is relatively mature, metal and ceramic combined to form a composite material is strong and beautiful. It is especially ideal for front teeth restoration and is favored by young beauty lovers. It is wear-resistant, corrosion-resistant, non-discoloring, non-deformation, is a more ideal restoration.
In addition to dental plastic surgery in the low-fusing porcelain and gold alloy inner crown joint restorations, precious metal porcelain crowns, in addition to non-precious metal porcelain crowns. For human tissue, occlusal function and aesthetic effect, the precious metal porcelain crowns are better than non-precious metal porcelain crowns, and the aesthetics can be chosen according to their own financial ability.
Method 2: All-Ceramic Dentistry
Why are all-ceramic crowns in cosmetic dentistry so attractive in the dental profession? Because many people, especially women, may be allergic to the metal in non-metallic porcelain crowns. This allergic reaction can occur several years after the crown is placed, manifesting itself as gum murmurings along the margins of the poorly placed full crowns, which eventually develops into unsightly purplish-red gum tissue.
For those who demand more, dentists believe that all-ceramic crowns offer more predictable and desirable aesthetic results. However, to date, no all-ceramic crown has the same durability and longevity as a metal crown.
2, oral cancer prevention
1, new mouthwash to prevent oral cancer
A gene therapy mouthwash holds promise for preventing oral cancer by eliminating undesirable tumors before they become malignant. The method attacks mucosal spots that are not yet cancerous by releasing a virus controlled by a genetic code that kills cells containing cancer-causing genes.
Scientists have known for the past 20 years that all cancers start with genetic defects. These genes, which accumulate over a lifetime and usually include six or more defects, cause cells to grow unchecked and spread throughout the body.
2. Drinking black tea can help prevent oral cancer
The tea polyphenols contained in black tea can stop the cancerous process of oral cell DNA and help prevent oral cancer.
Scientists selected 15 patients for a year of observation. These patients all suffered from oral leukoplakia, a common precancerous condition in which white patches appear on the patient's tongue and oral mucosa. Typically, 50 percent of white patches transform into oral cancer. However, by drinking black tea three times a day, the patients' leukoplakia was significantly relieved, and some white spots even disappeared.
3, compounds in soy can prevent oral cancer
Reportedly: soy-based products have many health functions, including the prevention of breast, colon and prostate cancer. Now, a new study proposes that a compound found in soybeans also prevents oral cancer. The compounds, called Bowman-Birk inhibitors, are extracts of soybeans. Researchers focused on mucosal leukoplakia, a precancerous stage of oral cancer, and found that the compound in soy effectively prevented mucosal leukoplakia from developing into oral cancer.
4, eat curcumin food to help prevent oral cancer
Expert research has found: eat more ginger, mustard, curry and other curcumin-rich foods, help prevent oral cancer. Let seven patients with precancerous lesions of oral cancer to take home cooking commonly used curcumin, three months after two patients with oral cancer leukoplakia symptoms were significantly improved. In addition, in animal experiments, researchers will PUMA gene injection into the mouse body, less than 1 month, the mouse oral cancer disappeared 2/3, proving that the PUMA gene to curb the growth of mouse tumors have a good effect. This study is still in the animal experimental stage, to be practically applied to the clinic there is still a period of time.
