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

Teledentistry utilization by oral health professionals and policy considerations: A mixed methods case study

OBJECTIVES

To examine variations in the delivery of teledentistry after the COVID-19 pandemic and to explore oral health professionals' utilization of various teledentistry modes of delivery.

METHODS

In this mixed methods case study, we collected teledentistry claims data from patient electronic health records (n = 78,756) encompassing various types of teledentistry utilization in clinical settings and through community outreach from a Dental Support Organization (DSO) in Oregon from January 2021 to November 2022. We analyzed the patient demographic and claims data using descriptive statistics and logistic regression analyses to identify patterns of teledentistry service delivery. Qualitatively, we conducted virtual interviews (n = 13) through Microsoft Teams with oral health professionals about their experiences with teledentistry utilization. We used inductive and deductive coding to code individual transcripts and identify common themes among provider experiences.

RESULTS

Out of the 78,756 electronic health record claims for teledentistry, 75.7% used synchronous audio, 13.4% used synchronous video, and 10.9% used asynchronous teledentistry methods. We observed a 8.6% increase in synchronous audio teledentistry utilization at the end of the study period, compared with a 4.2% increase in synchronous video and a 4.4% decrease in asynchronous teledentistry. Oral health professionals interviewed reported choosing the type of teledentistry delivery based on patient and provider access to the virtual teledentistry platform.

CONCLUSION

Oral health professionals' knowledge of and experiences with teledentistry need to be considered when developing policy and best practices for the use of teledentistry for patient care.

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. The aim of this review is to comprehensively summarize available SRs and provide evidence on the impact of teledentistry on access to oral care, patients' and oral healthcare providers' outcomes, quality of oral health care and costs. This protocol has been registered with the International Prospective Register of Systematic Reviews (PROSPERO CRD42022373964). Six electronic databases including MEDLINE (Ovid), Embase (Embase.com), CINAHL (EBSCO), Web of Science, Cochrane Library and Epistemonikos will be searched for SRs of quantitative, qualitative, and mixed reviews evaluating teledentistry modalities involving both patients and/or oral health care providers (OHCPs). We will include studies published in English or French. The outcomes will include patients' outcomes (e.g., access to oral health care, patient-reported outcomes, and patient-reported experiences); patient indicators (e.g., clinical outcomes, adherence to treatment, adverse outcomes and costs); and OHCP indicators (e.g., diagnostic accuracy, barriers and enablers costs and equity). Two independent reviewers will perform data screening, data extraction and will assess the quality of included studies using AMSTAR 2 and ROBIS tools. Data will be synthesized narratively and presented by tables and graphs. We will report any overlap of primary studies in the SRs. A statement on the strength of evidence for each outcome will be provided if possible. This review will inform decision-makers, patients, OHCPs, and researchers on the potential effectiveness, benefits, and challenges of teledentistry and support them in making recommendations for its use. Results will be disseminated through peer-reviewed publications, presentations at conferences, and on social media.

What does teledentistry mean? Mapping of current definitions

Access to timely oral healthcare services is paramount for any oral healthcare system, as good oral health contributes to overall quality of life and wellbeing. Despite several initiatives' efforts, there are still persistent deficiencies in accessing oral healthcare. As a result, teledentistry is recognized as a promising and cost-effective intervention to reduce oral health inequalities, enhance patients' outcomes and experiences, improve oral healthcare providers' wellbeing, reduce costs, and contribute to environmental sustainability in dentistry. However, there is confusion in its terminology with many interchangeably used terms referring to this concept. Therefore, based on our research on systematic reviews on teledentistry, we define teledentistry as the use of technology for remote oral healthcare delivery between patients and oral healthcare providers or between healthcare providers. Its goals are to facilitate access to care, reduce oral health inequalities, mitigate the economic impact of oral diseases and treatment, and foster interprofessional collaboration.

Applying an extended theoretical approach to identifying Canadian dental students' acceptance of teledentistry: A cross-sectional study

Objective

Teledentistry is a promising innovation for improving service quality and patient outcomes. While studies have shown the relevance of theoretical frameworks in understanding behaviour change predictors for telehealth implementation efforts, their application in dentistry is limited. This study aimed to test different theoretical approaches to identify the factors affecting dental students' behavioural intention to use teledentistry.

Methods

This cross-sectional study involved students in their final two years of undergraduate dental programmes, from three Canadian provinces (Quebec, Nova Scotia, and Saskatchewan) using an electronic self-reported questionnaire. Following descriptive analyses, we tested three theoretical models (the technology acceptance model, psychosocial model, and integrated model) using path analysis and multiple linear regression analysis. We analyzed the modifying effect of sociodemographic characteristics and prior use of teledentistry.

Results

Out of the 46 students who participated, the majority were female (53.5%) and aged over 25 years (62.8%). The three models successfully explained a substantial portion of the variance in behavioural intention to use teledentistry, ranging from 58.0% to 76.6%. Social role beliefs (p < 0.001) and control beliefs (p < 0.001) were the most significant predictors of behavioural intention to use. Prior use of teledentistry modified the association between control beliefs and behavioural intention to use teledentistry.

Conclusions

The original technology acceptance model was a good predictive model of behavioural intention to use teledentistry with perceived use as the strongest predictor. However, the integrated model performed the best in highlighting the relevance of training and education to foster teledentistry implementation in dental schools. The generalizability of the findings is constrained by the modest sample size, warranting larger studies for validation.
