Title:
Assessing oral cancer knowledge in Romanian undergraduate dental students.

Abstract:
The aim of this study is to investigate the level of Romanian dental students' knowledge regarding the oral cancer risk and non-risk factors as well as oral cancer signs, symptoms, and diagnostic signs. A total of 192 first- to sixth-year undergraduate dental students (mean age 22.20 ± 2.94 years) who consented to participate in the study filled in a questionnaire enquiring about their knowledge of oral cancer. A score of the oral cancer knowledge was calculated for each participant based on their correct answers. Regarding the knowledge of oral cancer risk factors, the vast majority of the students correctly recognized tobacco (96.8 %), having a prior oral cancer lesion (85.1 %), the consumption of alcohol (77.7 %), and older age (64.2 %). Respectively, 87.7 and 54.3 % knew the tongue and the floor of mouth to be the most common oral cancer sites. Of the students, 71.3 % agreed that oral cancer examinations for those 20 years of age and older should be provided during regular periodic health examinations, 92.9 % considered that patients with suspicious oral lesions should be referred to specialists, and 84.6 % agreed that oral cancer examinations should be a routine part of a comprehensive oral examination. A significant association was found between the year of study in the dental school, age, and knowledge of the oral cancer knowledge scores. Although students' knowledge increased with academic year, there is a clear need to enhance the dental curricula in oral cancer clinical training in oral cancer prevention and examination for dental students.
