Background: Halitosis or oral malodor is defined as an unpleasant breath odor. It can become a serious problem affecting individuals’ social communication and self-confidence. Furthermore, it is a discomforting issue for the people around the person affected, because they consider it embarrassing to inform the person of the problem. Aim: This study was designed to measure self-perception, knowledge, and awareness of halitosis among female university students in Saudi Arabia. Materials and methods: A cross-sectional survey was implemented with 392 volunteer participants who responded to a questionnaire on their self-perception, knowledge, and awareness of halitosis. Results: The response rate was 89.1% (392/440). Self-perception of halitosis was low (21.4%), whereas a larger percentage (78.1%) indicated noticing people with bad breath. Most participants (80.4%) thought that the gastrointestinal tract is the primary source of halitosis. Seventy-seven percent preferred using personal methods such as mouthwash and chewing gum to treat oral malodor. According to 82.1% of respondents, a dentist is the most appropriate professional to treat halitosis. Conclusion: The investigation revealed low self-perception and limited knowledge regarding halitosis. Therefore, the role of dentists in informing and educating their patients concerning oral malodor should be enhanced. Public education about the causes of and possible ways of managing bad breath should be increased.

Road traffic crashes represent a substantial global public health issue. In Saudi Arabia, which is the focus area of this research, road traffic crashes kill over 130,000 people annually, accounting for almost 5% of deaths in that country. A cross-sectional study with 316 participants holding a valid Saudi driver’s license was conducted via the internet from December 2019 to March 2020 to collect information about the prevalence of risky driving habits among Saudi drivers. The sample was predominantly men and aged between 20 and 39, which is representative of the population of drivers in Saudi Arabia. Drivers generally reported engaging in safe behaviors, although they did state that they drove above the legal speed limit, drove aggressively around slow drivers, and became distracted while driving with some frequency. Multivariate analyses suggested men took more risks than women and younger drivers took more risks than older ones. We conclude that the behavior among drivers in Saudi Arabia generally matches those in other cultures and countries, with men and young adults taking the most risks while driving. Preventative strategies should be developed and implemented in Saudi Arabia.
