Knowledge and attitude of pregnant women in Urmia, Iran, about oral health care during pregnancy.

Objectives: Physiological changes during pregnancy make mothers susceptible to periodontal diseases, in particular gingivitis, which could be prevented by good oral hygiene. Therefore, their knowledge and attitude could affect their oral hygiene and general health. This study therefore aimed to investigate the knowledge, attitude, and practice regarding oral hygiene, of pregnant women living in a city in Iran. Material and Methods: It was a cross‐sectional study that was performed in Urmia City in 2019. After completing an informed consent form, pregnant women completed a specially designed questionnaire, which included questions on demographic characteristics and assessed participants' knowledge and attitude about oral health care during pregnancy. A clinical examination of each participant's oral cavity was performed and dental plaque index (PI), gingival index (GI), and number of decayed, missed, filled teeth (DMFT) index were recorded. Any correlations between participants' knowledge and attitude and oral health indices were evaluated. A paired t test and Pearson's correlation coefficient were employed for statistical analysis. Results: A total of 96 pregnant women (mean age of 29.11 ± 6.80 years) participated in this study. Among them, 67 had a moderate level of knowledge. There was no significant correlation between participants' knowledge, and attitude levels and educational level (p =.88 and p =.43, respectively). Also, there was no correlation between knowledge and attitude levels and GI, PI, and DMFT (p >.05). Conclusions: This study showed that the knowledge and attitude of the pregnant women who participated were not favorable and their oral hygiene needed to be improved.
