Objectives: Objectify the knowledge and attitudes of surveyed pregnant women and gynecological patients in regard to the role of oral health in pregnancies as well as oral diseases (gingivitis, periodontitis), pregnancy diseases (high blood pressure during pregnancy with the onset of pre-eclampsia, gestational diabetes, premature delivery as well as the birth children with low birth weight). To determine the level of knowledge within these groups of surveyed patients, the connection between attitudes of patients and their oral hygiene habits during pregnancy in relation to their level of education. The obtained survey results of both groups of examinees will be statistically analyzed, compared and valid conclusions drawn. Study design: A cross-sectional study Participants and methods: The examinees were divided into two groups. The first group consisted of 75 gynecological patients while the second consisted of 79 patients. Both groups of surveyed patients were patients from the General Women’s Healthcare Practice at the Knin Health Centre. This survey was conducted from 15 February to 13 March of 2022. The data was obtained through an anonymous survey consisting of 13 questions. Results: Information on oral health during pregnancy was sought by the pregnant women from the doctor in 34.67% of cases. Gynecological patients sought this information from their dental medicine doctors in 65.82% of cases. In 26,67% of these cases, pregnant women searched for information on oral health on the Internet. Gynecological patients sought this information on the Internet in 11,23% of cases. Based on the above cited, the conclusion is that pregnant women are much more willing to search online for information on oral health. Gynecological patients prefer to discuss these topics directly with their doctors. The results of this survey indicate that pregnant women from all professional educational backgrounds possess insufficient knowledge compared to gynecological patients who showed a better knowledge and clearer attitudes. SUMMARY 43 Conclusion: Taking into consideration the results of this survey, the conclusion is that pregnant women in the City of Knin and its surroundings do not possess an adequate level of knowledge when it comes to oral health and oral diseases during pregnancy nor their impact on pregnancy diseases.
