Aim: The objective of this study was to evaluate the efficacy of a PowerPoint Presentation in
Up-grading the knowledge and awareness towards infant oral health care among expectant
mothers.
Methods: This was a cross sectional survey conducted in various maternity hospitals
throughout Jaipur city, India. A 15 minute PowerPoint Presentation based on infant oral
health care was presented to a total of 120 expectant mothers. The participants were made to
fill a 15-point questionnaire on the same subject before and after the presentation. Based on a
formulated scoring criterion, the knowledge and awareness level of each participant was
quantified pre-intervention and post-intervention. The data thus obtained was analysed using
descriptive statistics and chi square test, with the level of significance set at P<0.05.
Results: There was a very high statistical difference (p=0.000) between the mean scores of
the participants before and after the presentation, from 5.55 to 13.96 out of a maximum
possible score of 15. The range of scores improved from 0-14 pre-presentation to 9-15 post-
presentation. A significant improvement was seen in the mean scores of every socio-
demographic group (p=0.000). A relatively high number of participants (85.8%) agreed that
the presentation would change how they care for their child in the future.
Conclusion: Based on the results of the study, it can be concluded that the use of audio-visual
aids is beneficial in improving the knowledge and awareness towards infant oral health care
among expectant mothers. Further research can be conducted to evaluate different designs
of various audio-visual aids and their long-term efficacy catering to different socio-
demographic groups.
