Methods: : In this historical cohort study, 200 women including 100 pregnant women as case group and 100 women as control group, matched regarding age, level of education, occupation, daily tooth brushing. Pregnant women were all under 40 years old, in their second or third trimester without any systemic disease. They did not smoke or take any drug with gingival hyperplastic effect. Gingival indices indicating gingival inflammation and gingival hyperplasia were investigated, both clinically and by a dental probe in both group and analyzed by t-test.
Results:
Gingival indices showed a significant increase among pregnant women comparing to the controls (P<0.001).
Conclusions:
Pregnancy increase gingival hyperplasia. The performance of an experimental study, to determine the role of training pregnant women in the prevention of periodontal disease, is recommended.
