Abstract:
To develop and test the infant oral health educational audio-visual aid for pregnant women. The audio-visual aid containing evidence-based information about infant oral health care and early childhood caries prevention has been developed and test in 91 pregnant women having prenatal care at U-Thong hospital, Suphanburi province during October 1, 2008 to November 30, 2008. A questionnaire was developed to test knowledge and attitude of expectant mother before and after viewing the audio-visual aid. The efficiency and effectiveness index of the audio-visual aid were determined. The differences of knowledge score were tested with Wilcoxon match-pair signed-ranks test. Kruskal-Wallis test and Mann-Whitney test were used to determine factors related to knowledge score. The efficiency of an audio-visual aid is 87/70 and effectiveness index is 0.64. The pregnant women significantly improve their infant oral health knowledge (p < 0.05). The pre-test knowledge scores are statistically significantly related to income and educational level (p < 0.05). The post-test knowledge scores are statistically significantly related to educational level and occupation (p < 0.05). Approximately or more than 80% of the participants rate proper timing, speed and contents of audiovisual aid, and highly satisfaction on narration, illustration, easy understanding, interesting presentation, and useful. This infant oral health educational audio-visual aid promises to be an effective tool for pregnant women in providing anticipatory guidance regarding infant oral health care to prevent early childhood caries.
