Car Wash harmful to your teeth!

 In a report from the Sahlgrenska Hospital, we read that there is a risk of dental injuries if you work with car wash and car care.
 
  That acid can corrode the enamel have been known for a long time, but now a new study from the Sahlgrenska Academy also determine that strongly alkaline substances can damage teeth.

 

Subjects with high pH can include destroying the plaque so enamel becomes more vulnerable.
 

The study was conducted at the Department of Work and Environmental Medicine at the Sahlgrenska Academy and published in the scientific journal Journal of Dentistry.
 

- The study also shows that alkaline substances are harmful to the teeth, but the injury process is different compared to the exposure of acidic drinks or acid vapors in the industry, “said Fabian Taube, occupational hygienic and one of the researchers behind the study.
 

There were no cases of occupational injuries in the car wash and reconditioning, which attracted scientists’ interest. Common to all cases was the exposure of an alkaline degreasing agent that was sprayed on parts of cars. Product proved to have a pH of between 12 and 14, and is very alkaline.
  – Exposure to this medium led to tooth enamel surface was damaged and peeling away. The type of injury makes the risk of tooth decay and other dental injuries increases significantly, “says Jörgen Norén, the dentist and professor at the Sahlgrenska Academy.
  The alkaline degreasing agent used primarily in the food industry, including the cleaning of kitchens, but are also common in the car care industry.
  – Occupational Injuries in the teeth from exposure to alkaline medium is probably not as common as the damage caused by the acidic medium, but it becomes a problem when employers do not inform about the risks or do not provide access to the right protective equipment, “says Fabian Taube.
  The study suffered prolonged teeth for degreasing and other basic solutions. Enamel samples was subsequently examined by scanning electron microscopy and various spectroscopic methods. The researchers note that the rapid dissolution of organic material on the tooth surface, such as plaque.

 

The results suggest that although the organic components of enamel affected by exposure, as the enamel becomes more porous.
  – However, we have been able to show that the basic means changing the composition of the minerals that make up the bulk of enamel. Thus differs from the effects arising from exposure to acids, “says Fabian Taube.
  The study has been supported by, inter alia, Research Council for Working Life and Social Sciences (FAS) and Magnus Berg Walls Foundation
