Periodontal Health Status and Associated Factors: Findings of a Prenatal Oral Health Program in South Brazil

Objective. The aims of this study were to evaluate the periodontal health of pregnant women and to investigate the association of periodontal status with demographic and socioeconomic characteristics, as well as medical and dental history. Materials and Methods. A total of 311 pregnant women were interviewed to obtain sociodemographic data along with medical and dental histories. Clinical examinations were performed to record the presence of visible plaque, gingival bleeding, and caries activity. The periodontal condition was evaluated by Community Periodontal Index of Treatment Needs (CPITN) in one tooth of each sextant (16, 11, 26, 36, 31, and 46). Results. After the adjustment analysis, the presence of visible plaque remained the main determinant of gingival bleeding (OR = 2.91, CI = 1.91–4.48). First-trimester pregnancy status was also a predictor, with a lower prevalence of gingival bleeding observed in the second (OR = 0.87, CI = 0.77–0.99) and third (OR = 0.82, CI = 0.73–0.93) trimesters. Conclusion. In pregnant women, the presence of dental plaque and first-trimester pregnancy status were the main implicated factors predicting gingival bleeding.
