Yemeni dental and medical students have shown markedly poor oral health attitude and behavior. Further studies are required to reveal possible shortcoming in these schools' education process. Dental and medical curricula should emphasize the importance of proper oral hygiene, and further participation of medical and dental students in oral hygiene seminars is highly encouraged.

Background:A needle stick injury (NSI) is an accidental skin-penetrating stab wound from a hollow-bore needle containing another person's blood or body fluid. Healthcare workers (HCWs) including dental professionals are at an occupational risk of exposure to blood-borne pathogens following NSIs and sharps injuries (SIs). A thorough understanding of the safe practices while handling needles and sharps is crucial for HCWs to create a risk-free work place environment.Aims and Objectives:To assess the knowledge, attitude, practice, and prevalence of NSIs and SIs among dental professionals in a dental college at Bangalore.Materials and Methods:A cross-sectional survey was conducted in September 2012 using a structured, pretested, guided interview-based questionnaire that was administered to 200 dental professionals in a dental college at Bangalore to assess the knowledge, attitude, practices, and self-report information of NSIs.Results:In the present study, 81.5% of dental professionals were vaccinated against hepatitis B. A total of 27.5% participants had an NSI during the previous 12 months. About 41.80% of NSIs occurred during device recapping. Most common reason for failure to report the incidents of NSIs, as declared by 29.09% of the participants, included the fear of being blamed or getting into trouble for having an NSI.Conclusion:The knowledge of dental professionals on NSIs and their preventive measures are inadequate; however, training on Universal Precaution Guidelines, protocols regarding post-exposure prophylaxis, and safety devices has to be provided to prevent such injuries in future among the dental professionals.

Background The coronavirus outbreak (COVID-19) in China has influenced every aspect of life worldwide. Given the unique characteristics of the dental setting, the risk of cross-infection between dental practitioners and patients is high in the absence of adequate protective measures, and dentists may develop severe anxiety in relation to the current pandemic. The limited provision of services and widespread closure of dental practices have raised concerns among dental professionals about the financial impact. The present study assessed the frequency of dental practice closure during the pandemic’s first wave in several countries and whether closures and their associated factors differ between the private and non-private sectors. Methods An electronic cross-sectional survey questionnaire was sent to dentists in several countries, from April to May 2020. The survey assessed professional, practice related and country-level structural factors elucidating the reason for practice closure. Multilevel logistic regression was used to assess the association between practice closure and these factors, and differences were evaluated by sector type. Results Dentists from 29 countries (n = 3243) participated in this study. Most of the participants (75.9%) reported practice closure with significantly higher percentage in the private sector than the non-private sector. Greater pandemic-related fears were associated with a significantly higher likelihood of practice closure in the private (odds ratio [OR] = 1.54, 95% confidence interval [CI] 1.24, 1.92) and non-private (OR = 1.38, 95% CI 1.04, 1.82) sectors. Dentists in non-private rural areas (OR = 0.58, 95% CI 0.42, 0.81), and those in hospitals (overall OR = 0.60, 95% CI 0.36, 0.99) reported a low likelihood of closure. A high likelihood of closure was reported by dentists in the academia (OR = 2.13, 95% CI 1.23, 3.71). More hospital beds at the country-level were associated with a lower likelihood of closure in the non-private sector (OR = 0.65, 95% CI 0.46, 0.91). Private- sector dentists in high- income countries (HICs) reported fewer closures than those in non-HICs (OR = 0.55, 95% CI 0.15, 1.93). Conclusions Most dentists reported practice closure because of COVID-19, and greater impacts were reported in the private sector than in the non-private sector. Closure was associated with professional, practice, and country-levels factors.
