Periodontal disease as a risk factor for pre-eclampsia: a case control study

Area of Science:

• Obstetrics and Gynecology
• Periodontology
• Public Health

Background:

• Pre-eclampsia is a serious pregnancy complication with multifactorial causes.
• Periodontal disease, a common oral infection, has been investigated for its potential systemic effects.
• Understanding risk factors for pre-eclampsia is crucial for maternal and fetal health.

Purpose of the Study:

• To investigate the association between periodontal disease and pre-eclampsia.
• To control for known risk factors of pre-eclampsia in this investigation.

Main Methods:

• A matched case-control study involving 41 pre-eclamptic women and 41 healthy pregnant controls.
• Matching was performed for age, gravidity, parity, smoking, and prenatal care.
• Clinical periodontal parameters and dental health were assessed within 48 hours before delivery.

Main Results:

• Pre-eclamptic patients exhibited significantly greater mean probing depth and clinical attachment levels.
• Higher percentages of sites with bleeding on probing and deeper periodontal pockets were observed in the pre-eclamptic group.
• Periodontal disease was significantly associated with pre-eclampsia, with affected patients being 3.47 times more likely to have the condition.

Conclusions:

• Maternal periodontal disease during pregnancy is associated with an increased risk of pre-eclampsia.
• The findings suggest a possible role for periodontal disease in the development of pre-eclampsia.
• Given the multifactorial nature of both conditions, caution is advised when inferring causation.
