| خلاصه مقاله | Background: The idea of oral infections spreading to other systems has long been of interest to clinicians. The possibility of periodontitis and dental caries being a risk factor for preterm birth has been suggested in some researches. The purpose of this study was to investigate the relationship between periodontal health indicators and pregnant women's dental health status with preterm birth.
Methods: In this case-control study, 82 pregnant women were evaluated in the age range of 20-35 years old. The case group included mothers who gave birth to preterm infants (gestational age of less than 37 weeks), and the control group included mothers who had term labors (gestational age of 37-42 weeks).Oral examinations were carried out up to 48 hours after giving birth. Periodontal and dental health indicators, Including Decayed, missed, filled teeth (DMFT), periodontal pocket depth, clinical attachment loss, bleeding on probing, gingival index were recorded. The data were analyzed by SPSS17 through Mann-Whitney and Kruskal Wallis tests. Informed consent of all patients was obtained (IR.TBZMED.REC.1397.244).
Results: DMFT in mothers with preterm infants was 7.34 ± 4.45 and 5.68 ± 4.29 in control group (P=0.023). clinical attachment loss (P= 0.001) and bleeding on probing(P=0.012) were significantly higher in mothers with preterm infants, but there was no significant difference in Pocket depth (P=0.57) and gingival index(P=0.51) between groups.
Conclusion: There is a relationship between some maternal periodontal and dental health indicators and pre term births. Therefore, eliminating any oral sources of inflammation can reduce the risk of premature birth. |
