Background: Although there is increasing evidence to suggest an association between periodontal disease and adverse pregnancy outcomes, the issue remains controversial.
Study objective: This study tested the hypothesis that periodontal disease is a risk indicator for preterm delivery of low-birthweight infants.
Materials and methods: The study sample comprised 443 pregnant women with a mean (± standard deviation) age of 24.13 (±5.30) years. At first visit, maternal oral health status was assessed by the measurement of probing pocket depth and clinical attachment loss, and periodontal status was graded as absent, mild, moderate or severe. An association was sought between pregnancy outcomes and maternal periodontal status.
Results: While controlling for other factors, significant associations were found between pregnancy outcomes and maternal periodontal index scores.
Conclusion: This study provides further evidence that periodontal disease is a risk indicator for adverse pregnancy outcomes.
