Microbial profile of placentas from Tanzanian mothers with adverse pregnancy outcomes and periodontitis.

Aim: To investigate microbial profiles in placentas from a population of East African mothers with and without adverse pregnancy outcomes and with regard to their periodontal status.

Material And Methods: Thirty-six placentas from pregnant women from Tanzania were classified into three groups according to both pregnancy outcome and the mother's periodontal health. The microbial composition in each group was then compared using 16S rRNA metagenomics.

Do the clinical criteria used to diagnose periodontitis affect the association with prematurity?

In recent years, several studies have examined the possible relationship between periodontal disease in pregnant women and preterm birth. One of the difficulties facing these studies is the heterogeneity of the clinical criteria used to define periodontitis. The aim of this cross-sectional study was to determine the degree of association between maternal periodontitis and preterm birth according to different consensus definitions of periodontal disease.

Prevalence of sleep-related breathing disorders in children with malocclusion.
