Associations between systemic status, periodontal status, serum cytokine levels, and delivery outcomes in pregnant women with a diagnosis of threatened premature labor.

Background: Threatened premature labor (TPL) often results in preterm birth (PB). The aim of the present study was to evaluate the associations of periodontal and general health conditions with TPL and PB in relation to serum cytokine levels and the composition of subgingival plaque.

Methods: Eighty-eight women were enrolled in the study.

Associations of periodontal status with general health conditions and serum antibody titers for Porphyromonas gingivalis and Actinobacillus actinomycetemcomitans.

Background: The purpose of the present study was to evaluate associations of periodontal status with general health conditions and with serum antibody titers for Porphyromonas gingivalis (Pg) and Actinobacillus actinomycetemcomitans (Aa) in a Japanese population.

Methods: Subjects (1,314) aged 40 years or older were recruited for the study. Their periodontal status was evaluated using the community periodontal index of treatment needs (CPITN).
