Background. Since nurses are considered a role model in society, they should have sufficient knowledge, attitude, and practice in the field of oral hygiene. is study was aimed to assess the nurses’ knowledge, practice, and attitude towards toothbrush maintenance and use. Methods. In this cross-sectional study, 325 nurses working in hospitals affiliated to Kermanshah University of Medical Sciences were randomly recruited. Data collection tools included a demographic information form and a researcher- made questionnaire on knowledge, attitude, and practice regarding toothbrush maintenance and use. Data were analyzed by SPSS software using descriptive and inferential statistics (Mann–Whitney U and Kruskal–Wallis H). Results. e mean scores of nurses’ knowledge, attitude, and practice were 59.2 ± 16.4, 64.2 ± 20.6, and 51.4 ± 17.0 out of 100, respectively. ere was no statistically significant relation between nurses’ knowledge, attitude, and practice and their gender, age, level of education, and work ex- perience. Conclusions. Nurses had moderate knowledge, attitude, and practice regarding toothbrush maintenance and use, which is not very desirable given their role model. erefore, training courses are recommended to be held to increase the nurses’ knowledge, attitude, and practice regarding toothbrush maintenance and use. 1. Background Brushing is one of the most important and effective self-care methods which prevents oral diseases [1–3]. In addition, brushing reduces dental plaque and thus prevents decay and related diseases [4–8]. erefore, it is highly important for nurses to have adequate knowledge about the correct brushing method and also toothbrush maintenance, re- placement, and cleaning [9–12]. If the toothbrush is not properly maintained and used, it can cause oral infections and diseases [9–15]. Changing the toothbrush every 2.5–6 months and brushing for two minutes or more twice a day are some correct methods of toothbrush use [13, 16–22]. Today, as the largest group in the health sector, nurses have an important role in promoting health policies in the field of oral health [23–27]. erefore, adequate knowledge and practice and positive attitude regarding toothbrush maintenance and use is of special importance for nurses [28–32]. Surveys in Europe and the United States show that nurses consider oral health one of the most important nursing practices [1, 33]. A study in Malaysia showed that despite the limited knowledge of nurses about oral health, they had a good attitude to it [34]. e results of a study in India (2018) on oral health showed that 70% of nurses had poor knowledge, 83% had a positive attitude, and 69% had poor practice [30]. A study also showed that 82% of Iranian nurses had poor oral care practice [35]. e results of a study in Norway (2012) showed that 80% of nurses considered oral health an important issue, while 9.1% found patient oral care unpleasant [36].
