Frequent tooth brushing reduces risk of nonalcoholic fatty liver disease: Study
It has been recently found out that frequent tooth brushing was shown to significantly reduce the risk of developing the nonalcoholic fatty liver disease (NAFLD), as published in the Karger Journal.
Hence, Yamamoto K and colleagues from the St Luke's International Hospital, Tokyo, Japan conducted this study to evaluate the association between the frequency of daily tooth brushing and the development of nonalcoholic fatty liver disease (NAFLD).
The authors carried out a retrospective longitudinal study at the Center for Preventive Medicine at St. Luke's International Hospital, Japan. Data on all participants who underwent a health checkup during the study period were collected. A total of 25,804 people participated in the study. A total of 3,289 (12.7%) participants developed NAFLD. The mean age was 45.2 years, and 6,901 (26.7%) of the participants were male.
Nonalcoholic fatty liver disease (NAFLD) is an umbrella term for a range of liver conditions affecting people who drink little to no alcohol. As the name implies, the main characteristic of NAFLD is too much fat stored in liver cells. NAFLD is increasingly common around the world, especially in Western nations. In the United States, it is the most common form of chronic liver disease, affecting about one-quarter of the population. However, there is seldom literature that studies the association of tooth brushing and NAFLD.
