Effects of an oral health education program for pregnant women.

Purpose: The purpose of this study was to evaluate the gain in knowledge of oral health after education to pregnant women on dental anticipatory guidance and to determine how much of this information pregnant women retain over time.

Methods: The study consisted of 40 pregnant women. Inclusion criteria included: (1) between the ages of 21-40; (2) in 12-40th week of pregnancy; and (3) spoke English. During the first visit, all subjects were asked to complete a pre-test (24 questions), watch a ten minute presentation and complete the post-test (24 questions). During the second visit (4 weeks/1 month after the first visit), all subjects were asked to complete the follow-up test (24 questions).

Results: All of the tests (pre, post and follow-up) were scored and used to determine the changes in knowledge of the pregnant women after the presentation. The mean age for all 40 pregnant women was 26.88 (SD +/- 4.3) years and the mean number of weeks pregnant was 25.2 at the first visit. The mean overall correct scores for the pre-test was 12.9 (53.75%), post-test was 20.9 (87.08%) and follow-up test was 20.17 (84.05%). These overall scores show an improvement of 8 (33.33%, p<0.05) questions correct from the first to second test, and a digression of 0.73 (3.08%) questions correct from the second to third test.

Conclusions: These observations indicate that in this study population pregnant women's knowledge improved after a presentation on dental anticipatory guidance. These observations also indicate that after four weeks, pregnant women were able to retain most of the information, as only a slight digression in overall scores was noticed from the follow-up test to the post-test.
