A research group led by Assistant Professor Shinya Kageyama, Professor Toru Takeshita, and Emeritus Professor Yoshihisa Yamashita of Kyushu University Graduate School of Dentistry investigated the oral flora of infants who came for checkups at the age of 1 year and 6 months. It was found to be similar to the oral flora.This suggests that the oral flora of infants has rapidly approached that of adults over the past year and two months.
According to Kyushu University, the research group is continuing to conduct research on the oral flora of infants, and investigated the oral flora of 1 infants who visited Higashi Ward, Fukuoka City for checkups at the age of 6 year and 216 months. The results were compared with the survey results.
The results showed that the oral flora of 1 year and 6 month old infants was similar to that of their mothers from the time they were 4 months old.The influence of dietary habits during the weaning period has been suggested.In addition, some infants show signs of imbalances seen in adults, particularly those who consume more sweetened drinks and sweets, less fruit, are not fully weaned, and share eating utensils with their parents. It was more common in infants with
These results suggest that it is possible to maintain a healthy balance of oral flora by appropriately managing dietary habits during and immediately after weaning.The research group believes that the results of this study have the potential to establish preventive dental care that controls oral bacterial flora.
