A study conducted by researchers at the Catholic University of Minas Gerais (PUC-MG), concluded that the addition of 10% of Brazil nut oil or a mineral oil (liquid paraffin) to the composition of commercial toothpaste can prevent tooth decay and periodontal diseases.
The tests were performed for 90 days with three folders with different formulations of 30 people.
One group brushed their teeth with toothpaste on the market, without any alteration. Another used the same folder with nut oil and a third the toothpaste with mineral oil. At the end of the experiment there was a statistically significant reduction of problems associated with oral hygiene in two groups using paste with oils.
With the change in composition, toothpaste seems to be more effective in fighting bacteria. The research was published in the journal Brazilian Oral Research.
