The first in the country to set up a specialist clinic for pregnant women’s oral cavity, to provide special oral health protection for mothers-to-be and newborns. Dr. Ye Changchang, the specialist clinic for pregnant women in West China Dental Hospital, introduced that during pregnancy, women’s chances of oral conditions increase exponentially because of the endocrine environment of the body plus pregnancy reactions, as well as changes in living rules, eating habits and other factors. Since 1996, many studies at home and abroad have shown that pregnant women with periodontal disease are significantly more likely to have preterm births and low birth weight babies than those with healthy periodontals. After delivery, bacteria in the mother’s mouth can also be transmitted directly to the baby during intimate contact. In order to improve the rate of eugenics, Japan, the United States and other developed countries have carried out oral examination during pregnancy. This time, West China Stomatological Hospital set up a specialist clinic for pregnant women’s oral cavity, it is with the international advanced medical concept. Ye Changchang said, the best period of treatment is before pregnancy should go to the hospital, do a comprehensive oral examination, to eliminate hidden problems in the mouth. Miss the best period of treatment, should come to the hospital in the middle of pregnancy, that is, 3 months to 6 months, a relatively safe period. Oral diseases can develop faster during pregnancy, and regular checkups can ensure early detection and treatment, so that lesions are limited to a small area. In addition, pregnant women should pay more attention to oral care during pregnancy to maintain oral health and avoid acute inflammation. Pregnant women who are prone to dental caries can use fluoride topically as appropriate, and chewing xylitol gum in appropriate amount can also inhibit bacteria and clean teeth, which is beneficial to reduce the incidence of tooth decay.
