Article Synopsis
- The study wanted to find out how much dental students in six European countries know about oral potentially malignant disorders (OPMDs) and how they feel about learning more.
- The researchers gave an online questionnaire to final-year dental students to assess their knowledge, clinical experience, and preferences for future education on OPMDs.
- Results showed that while many students learned about OPMDs in school, not all had hands-on experience with patients, and there were gaps in their knowledge that need to be filled with more educational resources.
Article Synopsis
- Oral submucous fibrosis (OSF) is a chronic condition that affects the mouth and throat, and has a potential risk for becoming cancerous.
- The authors analyzed literature from 1956 to 2021 to calculate the overall malignant transformation rate (MTR), finding a 6% risk of malignancy across various studies.
- The study highlighted significant differences in malignancy rates based on ethnicity, with Pakistan showing the highest risk (27%), while the results indicated a need for further research to explore these discrepancies among different groups.
There is a strong association between tobacco use and the development of oral mucosal lesions, often with malignant potential. Nicotine is the primary component of tobacco responsible for addiction. The use of nicotine replacement therapy (NRT) aims to replace nicotine from cigarettes, allowing smoother transition to complete smoking cessation and greatly reducing risks of tobacco-related disease.

However, comparisons of POMR have been restricted by absence of standardised approaches to when it is measured, the ideal denominator, need for risk adjustment, and whether data are available. We aimed to address these issues and recommend a minimum dataset by analysing four large mixed surgical datasets, two from well-resourced settings with sophisticated electronic patient information systems and two from resource-limited settings where clinicians maintain locally developed databases.

Its accuracy and usefulness as a metric, however, particularly one that enables valid comparisons over time or between jurisdictions, has been limited by lack of a standardized approach to measurement and calculation, poor understanding of when in relation to surgery it is best measured, and whether risk-adjustment is needed. Our aim was to evaluate the value of POMR as a global surgery metric by addressing these issues using 4, large, mixed, surgical datasets that represent high-, middle-, and low-income countries.
