The use of mouthwash in Brazil grew 2277% from 1992 to 2007, shows a survey conducted by the dental surgeon Marco Antônio Manfredini, a researcher at the School of Public Health at USP (Universidade de Sao Paulo), based on information from the Brazilian Association Personal Hygiene, Perfumery and Cosmetics. From 2002 to 2007, the increase was 190%.
For Manfredini, encouraging the indiscriminate use of mouthwash should be criticized. "We observed a large investment in inducing the use of the product. And it's important to say that, unlike the paste, brush and floss, mouthwash does not have universal statement. We need to concentrate to use specific cases."
Besides not being essential to oral health, the frequent use of mouthwash with alcohol increases the risk of cancer of the mouth and pharynx. A scientific review published in late 2008 in the journal of the Australian Academy Dental compiled studies from around the world who have found this relationship. According to the researchers, there is enough evidence to accept the idea that mouthwash with alcohol contributing to higher rates of oral cancer.
Much of the products sold in Brazil contains ethanol. A Brazilian study conducted with 309 patients last year and published in the Journal of Public Health also found the same association. Some brands have up to 26% alcohol, and there are people who use every day. Today there are products on the market without alcohol, which should be the chosen, the oncologist said Luiz Paulo Kowalski, director of the Department of Head and Neck Surgery, Hospital A. C. Camargo and an author of the work.
According to Anvisa (National Agency for Sanitary Vigilance), manufacturers are obliged to inform the packaging the presence of alcohol in the composition. The alcohol present in enxaguantes contributes to increasing rates of oral cancer in a manner similar to alcohol - and it is known that alcohol is a second risk factor for the disease, after smoking, increasing from five to nine times the risks.
Joke that the person drinks without enjoying the good part of the drink. The product is not because alcohol is an antiseptic, but because it is a very efficient vehicle, industrially convenient and very cheap. So no alcohol versions tend to be more expensive, explains Alberto Consolaro dentist, professor of pathology, Faculty of Dentistry of Bauru, USP.
Alcohol is not a cancer-causing agent in isolation, but an enzyme the body turns into acetaldehyde, a substance that can alter cells in the mouth and cause tumors in the region. The problem is to use the product every day, because the harm of not giving the cells time to repair. The use of mouthwash [alcohol] needs further study, but it's something like what happens with the cigarette, the more exposure the greater the risk, says Kowalski. Therefore, dentists recommend the use of the product without alcohol, be manipulated, either brand.
The product is a good helper to clean the mouth but do not contain alcohol. People think that burning a mouth rinse is best, but good product need not give that feeling. The antiseptic is not Alcoa, says Consolaro.
Dentists recommend using mouthwash after surgery, tooth scaling, cases of high incidence of tooth decay, gum disease and for people who have no motor skills to accomplish a good brushing. For the general population, the use is optional, although much of this type of product advertising to suggest that he fights bad breath.
From the viewpoint of oral hygiene, it is not necessary. Who has good oral hygiene usually does not have halitosis - and, if so, is not the mouthwash will solve the problem, says Manfredini.
