Oral Health Knowledge and Self-Reported Practices among a Sample of University Students in Jordan

Abstract

This cross-sectional survey gathered data on dental health knowledge from 21- to 23-year-old university students in Jordan, including self-reported dental health behaviors and factors affecting regular dental attendance. A representative random sample of 806 students in their final academic year was surveyed. A self-administered questionnaire resulted in a 93.2% response rate. The majority (51.8%) were able to correctly identify the definition of dental plaque and were aware of the periodontal diseases which could be prevented by brushing and flossing. Nonetheless, there are more participants who incorrectly believed that fluoride in toothpaste cleans and whitens teeth (78% and 65%, respectively), and only 7% recognized that fluoride can heal initial cavities. Female students have a significantly higher level of oral health knowledge than their male counterparts (p < 0.001). Tooth brushing at least once and twice a day was claimed by 57.8% and 14.1% respectively. Only 10.4% spend more than two minutes for tooth brushing which is performed before going to bed by 56.2% of the study population. Thirty-three percent of male students and 36% of female students went to the dental clinic at some time during the last year and were more likely to receive dental extraction (41.1%) or dental filling (32.2%) at their last visit to the dentist. The mass media (TV, radio, newspapers, and magazines) were found to be the number one source of dental health information while formal academic courses and extracurricular activities at the university came at the bottom of the list of the six potential sources for health awareness information. Appropriate recommendations aimed at raising the oral health awareness and increasing the demand for dental health services among university students are suggested.
