The relationship between periodontal diseases and preterm low birth weight / 实用口腔医学杂志

ABSTRACT

Objective:To assess the periodontal diseases as a possible risk factor for preterm and low birth weight. Methods: A population-based, cross-sectional study was carried out in Hubei. The samples were chosen randomly by the rule of admittance. Socio-demographic information relating to health and maternal habits was collected through a questionnaire. The clinical parameters were debris index-simplified (DI-S), sulcus bleeding index (SBI), probing pocket depth (PD) and clinical attachment loss (CAJ). The birth time and weight were recorded. The result was analyzed with chi-square test and logistic regression analysis.Results: The incidence of preterm low birth weight was 12.3%. The gingivitis and periodontitis were diagnosed in 86.6% and 64.2% of preterm low birth weight cases. The odds ratio of having gingivitis and preterm low birth weight was 1.30(95%confidence interval 0.53-3.22). The odds ratio of having periodontitis and preterm low birth weight was 2.69(95%confidence interval 1.37-5.27). Conclusion: The periodontal diseases of pregnancy can be regarded as an important risk factor for preterm low birth weight.
