To demonstrate the role of periodontal treatment (PT) in the prevention of preterm delivery (PD).A comparative prospective study of two groups of pregnant women with threatening PD was carried out at the Department of Obstetrics and Gynaecology of the University of Szeged: group A (n = 39) comprised patients who were merely examined dentally for periodontitis, and group B (n = 44) consisted of patients who received periodontal treatment during pregnancy.Periodontitis was identified in 19 cases (48.7%) in group A and in 18 cases (40.9%) in group B. The mean birth weight of the newborns was significantly higher in group B (3,009.1 g) than in group A (2,580.8 g; p = 0.007). The rate of premature birth was significantly lower in the group who received PT (p = 0.012, odds ratio = 3.5, 95% confidence interval = 1.38-8.86).The PT of pregnant women can decrease the rate of premature birth and consequently lead to a better neonatal health outcome.
