Investigation on the influence of periodontal disease in gestation on small for gestational age
Abstract
Objective The purpose of this study was to investigate the relevant social and environmental factors affecting the occurrence of periodontal diseases during pregnancy in pregnant women and to analyze the influence of the periodontal status of women in the second trimester of pregnancy on small for gestational age (SGA) delivery.Methods A total of 215 pregnant women were enrolled in this study in the Department of Periodontology of the West China Hospital of Stomatology of Sichuan University from May 2015 to May 2018. Periodontal parameters, such as bleeding on probing (BOP), probing depth (PD) and clinical attachment loss (CAL), were recorded at 16-24 weeks of gestational age. Subjects were divided into the periodontitis (n=32) group, gingivitis (n=171) group and periodontally healthy (n=12) group according to their periodontal conditions. With the patient′s informed consent, the patient decided whether to receive periodontal treatment. Basic and socioeconomic information was collected through questionnaires. After delivery, subjects were divided into the SGA group and non-SGA group according to their birth results. The periodontal clinical indicators, questionnaire results and delivery results were compared among the groups.Results The mean PD (P=0.005, r=-0.192) and BOP% (P=0.003, r=-0.199) were negatively correlated with economic income. The family income in the periodontitis group was significantly lower than that in the healthy group and the gingivitis group (P 0.05). PD ≥ 5 mm% and PD ≥ 4 mm% (P 0.05).Conclusion Family income and dental flossing use have an impact on the incidence of periodontal diseases during pregnancy. The severity of periodontitis in pregnant women is correlated with the incidence of SGA.
