85 pregnant women were observed, aged 19 to 30 years old, 8 to 24 weeks of pregnancy. Of 53 cases, there were multiple demineralized lesions of the dental neck, 23 cases of enamel lesions, and 8 cases of hard tooth wear. Use 2% methylene blue staining to diagnose caries and enamel demineralization, oral health care, teeth remineralization treatment of teeth, divided into 4 groups, the first group of 25 cases, daily with 3% ремодент liquid local application 20 A total of 20 days. The second group of 20 cases, each day with calcium nitrate and acidic ammonium phosphate local application of 10 minutes for a total of 7 days. The third group of 20 cases, 3% local application daily ремодент liquid helium neon laser penetrated 60 seconds for 5 days. Laser wavelength 632.8nm, power density 60mW / cm ~ 2.
