Background and Objective Studies performed over the last 15 years have suggested that periodontal diseases may be associated with adverse pregnancy outcomes. However, this association has not been found in all populations. The aim of this study was to evaluate whether periodontal status and the presence of specific periodontal pathogens may influence the incidence of adverse pregnancy outcomes. Material and Methods Pregnant women were clinically examined before 26th week of gestation, and divided in two groups: non‐periodontitis and periodontitis. Microbial samples were obtained in the periodontitis group and processed by anaerobic culturing. After delivery, data on the pregnancy outcome were taken; mother's socio‐demographic and risk factors were obtained at inclusion. Simple and multiple regression analysis were performed. Results One hundred and seventy women were included in the study (116 non‐periodontitis and 54 with periodontitis). The incidence of preterm ( PTB ) and low‐birth weight ( LBW ) was 2.94% and 3.53%, respectively. Periodontal status did not show any association with adverse pregnancy outcomes. The presence of Eikenella corrodens was significantly related to PTB ( p = 0.022) and the presence Capnocytophaga spp. was related to LBW ( p = 0.008). The multivariate analyses showed a significant association between PTB and newborn weight and counts of E. corrodens . Maternal health and counts of E. corrodens were significantly associated with PTB or LBW . Conclusion The clinical periodontal condition was not associated with adverse pregnancy outcomes in a S panish Caucasian population with medium‐high educational level. The presence and counts of E. corrodens and the presence of Capnocytophaga spp. showed a significant association with PTB and LBW , respectively, in the bivariate and/or multivariate model.
