Brief Summary

The main causes of adverse pregnancy outcome(s) are reported to be maternal infection and placental, foetal, or uterine pathosis. Maternal infection and placental pathosis appear to be the most important causal factors, possibly causing pre-term labour, premature pre-term membrane rupture, or result in medically induced pregnancy interruption. There are reports of a link between poor maternal periodontal health and composite adverse pregnancy outcome of pre-term low birth weight (PLBW). however, the reason for such correlation is still not clear. In the current study the investigators will try to follow a possible path between periodontal infection and uterus physiology, by signaling out inflammatory markers that may leak from the gingival fluid into the serum and from there to the amniotic fluid. the investigators will collect GCF, serum and amniotic fluid from patients undergoing elective amniocentesis and analyse inflammatory markers in the collected samples.

Outcome Measures

Primary Outcomes (1)

  • cytokines levels

    Using ELISA we will quantify the levels of inflammatory markers such as IL-6, TNFα and IL-1β.

    analysed at the end of sample collection. participants will be followed for the duration of pregnancy, an expected average of 5 months

Secondary Outcomes (1)

  • presence of endotoxin and perio-pathogens DNA in the serum and amnionic fluid

    analysed at the end of sample collection. participants will be followed for the duration of pregnancy, an expected average of 5 months

Study Arms (2)

periodontitis patients

according to american academy of periodontology classification of periodontal diagnosis.
