The research team of the School of Dentistry of Tohoku University in Japan recently pointed out in the medical journal Neurology that the health of teeth and gums is related to the shrinkage of the hippocampus of the human brain. The shrinkage rate of the brain is faster, and if the average elderly person loses 1 tooth, the rate of brain decline will be accelerated by 1 year.
according to”News1“reported that Tetsushi Yamaguchi, a lecturer in the Dental Function Department of Tohoku University Hospital, Sendai City, Miyagi Prefecture, Japan, led a research team to conduct a survey on dental health, past medical history and memory among middle-aged people over the age of 55; Unharmed adults were tracked and observed for a period of 4 years, and then the number of teeth and whether they had gum disease were investigated. At the same time, MRI images were used to examine the volume of the hippocampal gyrus of the brain.
The results analyzed by the research team showed that the number of teeth, the health of the gums and the condition of the brain all interacted with each other. Among them, people with mild gum disease with fewer teeth and people with severe gum disease with more healthy teeth, their left hippocampus shrinks faster than ordinary people, and in the early stage of Alzheimer’s disease (senile dementia), The size of the hippocampus will be reduced.
The research team said that the left hippocampal gyrus shrunk quickly in people with mild gum disease who had fewer teeth, with an average reduction of 1 tooth, and the speed of brain aging was accelerated by 1 year; , the atrophy rate of the hippocampus will not be reduced, an average increase of 1 tooth, and the rate of brain aging will be accelerated by 1.3 years.
In view of this, the research team pointed out that maintaining the health of teeth and gums not only affects oral hygiene, but also improves the condition of the brain. “It is advisable to treat gum and tooth diseases as early as possible through regular dental check-ups.”
