Introduction: In a previous study, we showed that the growth of Campylobacter rectus is stimulated by the presence of female sex hormones in the culture medium. In the present study, we examined the relationship between C. rectus levels in the saliva and the periodontal status of pregnant women.
Methods: Unstimulated whole saliva was collected from 22 pregnant and 15 nonpregnant women. Periodontal pocket depth (PD) and bleeding on probing (BOP) were recorded. A quantitative real-time polymerase chain reaction was performed to determine the concentrations of suspected periodontopathogenic bacteria in the saliva samples. In addition, the concentration of estradiol in the saliva samples was measured by enzyme immunoassay.
Results: The average age, number of teeth, and total number of bacteria in the saliva of subjects in both groups were similar. The percentage of sites with a PD = 4 mm and the salivary estradiol concentrations were significantly higher in pregnant women than in non-pregnant women. In addition, the percentage of BOP sites and the C. rectus levels in the saliva of the pregnant women tended to be higher than in non-pregnant women, although these differences were not statistically significant. There were positive correlations between C. rectus levels and estradiol concentrations, and between C. rectus levels and the percentage of sites with PD = 4 mm in the pregnant women.
Conclusion: These results indicate that C. rectus levels are higher in the oral. ora of pregnant women and that this may be associated with increased salivary estradiol concentrations. This may contribute to periodontal disease progression during pregnancy.
