Canada's First National Oral Health Research Strategy (2024-2030).

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).

Caries lesions progression in adults: A prospective 2-year cohort study.

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 dental COVID-19 paradox: Disparity in behaviors inside and outside dental schools in Canada.

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.

Microstructure and Mechanical Behavior Comparison between Cast and Additive Friction Stir-Deposited High-Entropy Alloy AlCoCrFeNi.

High-entropy alloys (HEAs) are new alloy systems that leverage solid solution strengthening to develop high-strength structural materials. However, HEAs are typically cast alloys, which may suffer from large as-cast grains and entrapped porosity, allowing for opportunities to further refine the microstructure in a non-melting near-net shape solid-state additive manufacturing process, additive friction stir deposition (AFSD). The present research compares the microstructure and mechanical behavior of the as-deposited AFSD AlCoCrFeNi to the cast heat-treated properties to assess its viability for structural applications for the first time.

Investigating the perceptions and experiences of Canadian dentists on dental regulatory bodies' communications and guidelines during the COVID-19 pandemic.

Objective: Dental regulatory bodies aim to ensure the health and safety of dentists, dental staff patients and the public. An important responsibility during a pandemic is to communicate risk and guidelines for patient care. Limited data exist on the perceptions and experiences of dentists navigating new guidelines for mitigating risk in dental care during the pandemic.

Teledentistry for improving access to, and quality of oral health care: A protocol for an overview of systematic reviews and meta-analyses.

Digital technologies are becoming essential to address and optimize the suboptimal performance of healthcare systems. Teledentistry involves the use of information and communication technology to improve access to oral health care and the quality of oral health care delivery. Several systematic reviews (SRs) have been conducted to synthesize evidence on the effectiveness of teledentistry but with conflicting results.

Community health worker navigation to improve allostatic load: The Integrated Population Health (IPOP) study.

Background: Social determinants of health (SDOH) and cumulative stress contribute to chronic disease development. The physiological response to repeated stressors typical of lower-income environments can be measured through allostatic load - a composite measure of cardiovascular, metabolic, and immune variables. Healthcare systems have employed patient navigation for social and medical needs to improve SDOH that has demonstrated limited impact on chronic disease outcomes.

The Fruit and Veggies for Kidney Health Study: A Prospective Randomized Trial.

Rationale & Objective: Providing fruits and vegetables (F&Vs) to health care system patients with elevated urine albumin-creatinine ratio (ACR) reduced ACR, slowed chronic kidney disease (CKD) progression and reduced cardiovascular disease (CVD) risk factors in previous studies. This study evaluated a community-based strategy in lower-income populations to identify African Americans with elevated ACR before health care system involvement and sustain them in a 6-month F&V protocol with (F&V + Cook) and without (F&V Only) cooking instructions, with the hypothesis that adjuvant cooking instructions with F&Vs would further reduce ACR.

Study Design: Prospective, randomized, parallel 2-arm design.

Personal protective equipment during COVID-19: A natural history of dental and dental hygiene regulatory guidance in Canada.

Background: Due to the evolving nature of COVID-19, there is evidence that COVID-19-specific infection prevention and control guideline (IPCG) documents formulated for oral health care settings are also changing rapidly. To better inform future policies, a comprehensive review of all IPCG documents across different phases of restrictions for oral health care practitioners is required.

Types Of Studies Reviewed: A search was performed for documents shared from March 2020 through January 2022 on websites of oral health regulatory authorities in Canada's 10 provinces and 3 territories.

Validity and reliability of the COVID-19 Anxiety Syndrome Scale in Canadian dentists.

Background: The COVID-19 pandemic has resulted in a high level of mental health problems for the population worldwide including healthcare workers. Several studies have assessed these using measurements for anxiety for general populations. The COVID-19 Anxiety Syndrome Scale (C-19ASS) is a self-report measure developed to assess maladaptive forms of coping with COVID-19 (avoidance, threat monitoring and worry) among a general adult population in the United States.

Salivary Cortisol and Anxiety in Canadian Dentists over 1 Year of COVID-19.

The dental profession has endured unprecedented disruption amid COVID-19. Novel stressors have included a high risk of occupational exposure to COVID-19, financial losses, and stricter infection prevention and control requirements. The present study investigated the longitudinal impact of COVID-19 on the stress and anxiety levels of a cohort of Canadian dentists ( = 222) between September 2020 and October 2021.

Identifying potentially undiagnosed nontuberculous mycobacterial lung disease among patients with chronic obstructive pulmonary disease: Development of a predictive algorithm using claims data.

Nontuberculous mycobacterial lung disease (NTMLD) is a debilitating disease. Chronic obstructive pulmonary disease (COPD) is the leading comorbidity associated with NTMLD in the United States. Their similarities in symptoms and overlapping radiological findings may delay NTMLD diagnosis in patients with COPD.

Indicators of integrating oral health care within universal health coverage and general health care in low-, middle-, and high-income countries: a scoping review.

Background: The World Health Organization (WHO) has recently devoted special attention to oral health and oral health care recommending the latter becoming part of universal health coverage (UHC) so as to reduce oral health inequalities across the globe. In this context, as countries consider acting on this recommendation, it is essential to develop a monitoring framework to measure the progress of integrating oral health/health care into UHC. This study aimed to identify existing measures in the literature that could be used to indicate oral health/health care integration within UHC across a range of low-, middle- and high-income countries.

Virtual Oral Health across Canada: A Critical Comparative Analysis of Clinical Practice Guidances during the COVID-19 Pandemic.

During the COVID-19 pandemic, teledentistry was suggested as a cost-effective and promising approach to improve access to oral health care. In response, Canadian provincial and territorial dental regulatory authorities (DRAs) published teledentistry-related clinical practice guidances (TCPGs). However, an in-depth comparison between them is needed to understand their gaps and commonalities so as to inform research, practice, and policy.

Mental Health Treatment Reported by US Workers before and during the COVID-19 Pandemic: United States (2019-2020).

The COVID-19 pandemic introduced a significant and unprecedented exacerbation of community mental health challenges. We compared the prevalence of mental health treatment (MHT) before and during the COVID-19 pandemic among US workers. Self-reported MHT data (N = 30,680) were obtained from the Sample Adult data of the National Health Interview Survey (2019 and 2020).

Canadian dental hygienists' experiences and perceptions of regulatory guidelines during the COVID-19 pandemic: a qualitative descriptive analysis.

Background: In Spring of 2020, due to the COVID-19 pandemic, Canadian provincial dental hygiene regulatory bodies implemented new practice guidelines. Reports of stress, anxiety and conflict experienced by dental hygienists have been linked to miscommunication between oral health regulators at this time. Limited data exists on the perceptions and experiences of dental hygienists navigating new guidelines for dental hygiene care during the pandemic.

COVID-19 incidence and vaccination rates among Canadian dental hygienists.

Background: Oral health care settings potentially carry a high risk of cross-infection due to close contact and aerosol-generating procedures. There is limited evidence of the impact of COVID-19 among dental hygienists. This longitudinal study aimed to 1) estimate COVID-19 incidence rates among Canadian dental hygienists over a 1-year period; and 2) estimate vaccination rates among Canadian dental hygienists.

Required sample size to detect mediation in 3-level implementation studies.

Background: Statistical tests of mediation are important for advancing implementation science; however, little research has examined the sample sizes needed to detect mediation in 3-level designs (e.g., organization, provider, patient) that are common in implementation research.

Infection Prevention Strategies Concordance in Canadian Dental Schools During the COVID-19 Pandemic.

Objective: The aim of this research was to identify variation in specific infection prevention and control (IPC) strategies across all dental schools in Canada and to evaluate the concordance concerning COVID-19 pandemic-related IPC strategies reported by clinic directors or IPC officers (CDs/IPCOs) and those reported by students, staff, and faculty in the schools.

Method: A cross-sectional analysis within a prospective cohort study. Participants in the cohort study reported IPC strategies used in their schools during April or May 2021.

Association Between the Metabolic Syndrome and Retinal Microvascular Diameters Among Police Officers.

Objectives: We examined the associations of the metabolic syndrome severity score (MSSS) and the metabolic syndrome (MetSyn) components with central retinal arteriolar equivalent (CRAE) and central retinal venular equivalent (CRVE).

Methods: Participants in this cross-sectional study were 253 officers from the Buffalo Cardio-Metabolic Occupational Police Stress study (2011-2014). The MSSS is a z -score that represents the severity of MetSyn and was estimated using a sex/race-specific equation and the five MetSyn components.
