Introduction: Periodontal disease is an infectious disease, and infection is a risk factor for adverse pregnancy outcome recently, periodontal disease has been investigated as a risk factor for preterm delivery and abortion. In this study we tend to measure gingival indices in mothers with early abortion comparing with who gives birth to healthy neonate.
Materials and methods: This cross sectional study was conducted on 60 pregnant women admitted to Imam Reza hospital Mashhad in 1389-90. 30 women who had early abortion were studied in experimental group and 30 women who had healthy were studied in control.attachment loss, probing Depths, gingival index and bleeding on probing were measured using a dental mirror and a periodontal probe.Data were analyzed by SPSS software version 11.5 and Chi square, Independent t test and Mann-whitney tests. P value less than 0.05 was considered significant.
Results: Mean AL(P=0.138), mean PD(P=0.232) and Gingival index(P=0.071) was not different in case and control groups.But The amount of bleeding on probing was significantly more in cases than controls (P=0.045).
Conclusion: Periodontal disease can't be a risk factor for early abortion.
