In a longitudinal observational study of 958 women, 30% had no periodontal disease at enrollment, 60% had mild periodontal disease, and 14% had moderate/severe periodontal disease. Of those with moderate/severe disease, 79% were black, suggesting that the rate of periodontal disease in the pregnant population mirrors that of the nonpregnant population, said Dr. Boggess of the University of North Carolina at Chapel Hill.
The literature shows that, compared with white women, black women have a higher rate of periodontal disease, she noted.
Black women also have a higher rate of preterm birth, and this was true in the current study, as well. Preterm birth occurred in 23% of the 471 black women in the study, compared with 6% of the 487 white women.
Furthermore, the study supports previous research that suggests periodontal disease is associated with preterm delivery. Delivery before 37 weeks' gestation occurred in 29% of those ...
