Acetylsalicylic acid causes tooth erosion?
Several published studies indicate that the use of acetylsalicylic acid may contribute to tooth erosion. These studies report laboratory studies (extracted teeth placed in water and acetylsalicylic acid solutions) and clinical case studies of people who ingested six doses of acetylsalicylic acid powder per day over a period of two to three years. In the laboratory study, the researchers looked at the surface of the enamel (outer layer) and dentin (structural layer below the enamel) of the extracted teeth immersed in the water solution with acetylsalicylic acid.

In the clinical study, the occlusal surface of the molars, lower premolars presented severe erosion, as did the lower anterior teeth on the side facing the tongue. The use of acetylsalicylic acid powder was the cause of erosion. (2)
Another study, with 42 children suffering from rheumatoid arthritis and taking acetylsalicylic acid tablets, chewing or swallowing them whole, showed severe erosion in the upper and lower primary molars and the first permanent molars. The 17 children who swallowed the tablets had no dental erosion. Thus, the study concluded that tooth erosion developed by children was due to the chewing of acetylsalicylic acid tablets. (3)
Acetylsalicylic acid can affect the structure of the tooth surface and, depending on how it is ingested, may cause irritation to the soft tissues of the mouth. Consult your dentist and your doctor if there is a recommendation for acetylsalicylic acid for the treatment of any health problem.

Bathroom dryers blow coconut bacteria into their hands, a study has found that hand dryers suck bacteria in the bathroom and blow in the hand. A study published this month in the journal Applied and Environmental Microbiology found that hand dryers, often present in public toilets, suck in the air from the site filled with fecal coliforms, and they blow back into their hand and the whole environment.
When we do our bathroom hygiene, we end up dumping our dirt in the environment. . Therefore, the bathroom can be understood as a place with a large amount of body fluids, such as urine, faeces, saliva and sweat.

Generic drugs have been sold in Brazil for over 11 years. According to a study by ProTeste (Brazilian Association of Consumer Protection), this type of medicine corresponds to 21% of sales of medicines in the country and 86% of Brazilians have had a brand-name drug replaced by its generic version. Even with increasing use, however, many people still wring their noses when they look at a generic medicine in the prescription.
