Recent years have seen significant positive changes and developments in oral health-related policy and data on oral health and oral health care in Canada. Simultaneously, on the international stage, the momentum for oral health and related research continues to build. These changes have led to an initiative to create Canada's first National Oral Health Research Strategy (NOHRS), which was recently published by the Canadian Institutes of Health Research-Institute of Musculoskeletal Health and Arthritis (Allison and Rock 2024).

Objective: Dental caries is one of the most prevalent chronic non-communicable diseases worldwide. There is a lack of evidence, especially in adult populations, documenting caries disease progression considering lesion severity, activity and tooth surface-level characteristics. The study aimed to investigate the extent to which primary active caries lesions in adults affect caries lesions progression compared with inactive caries lesions over a 2-year follow-up period, considering their severity, surface and tooth type.

- The study investigates the effectiveness of DNA barcoding for identifying crayfish species, revealing that while local barcoding gaps exist, only a few genera show global barcoding gaps meeting the typical threshold for species discovery.
- Analysis of mitochondrial COI sequence data from 81 crayfish species indicates that global barcoding gaps are below the previously suggested 10× threshold, leading researchers to propose a new ~5× threshold for better species identification.
- The findings suggest that the existing taxonomy of most crayfish species may be insufficient, indicating a need for taxonomic revisions even for species with identifiable local barcoding gaps.
Objective: To describe the personal and professional behavior and assess the perceptions of protection and fear of contracting coronavirus disease 2019 (COVID-19) among faculty, staff, and students from all 10 Canadian dental schools during the second year of the pandemic.
Method: Participants from a Pan-Canadian prospective study answered monthly questionnaires about their activities between April 2021 and March 2022. In May 2022, additional questions were asked about their perception of protection, fear of infection, and instances of COVID-19 testing.
