摘要

Objectives

This survey aimed to explore the attitudes, knowledge, and acceptance levels of consumers and dentists towards saliva as a diagnostic tool for periodontitis, in order to identify the potential advantages and barriers to its implementation in periodontitis diagnosis.

Methods

With approved human ethics from The University of Queensland (2023/HE000413), this cross-sectional questionnaire study included 69 consumers and 32 clinicians, all of whom completed the survey between September 2023 and March 2024. We proposed a four-step saliva diagnosis workflow: (1) Collect saliva at home or in a dental clinic; (2) Send the sample to the laboratory for analysis; (3) Provide test results to the dentist and patient; (4) Schedule further consultation or treatment if necessary. Attitudes towards the proposed saliva diagnosis protocol were analysed in relation to consumers’ demographic characteristics and clinicians’ professional backgrounds.

Results

Most consumers surveyed were aged 20–29, while most clinicians (~ 56%) were general dentists. Approximately 80% of consumers expressed optimistic views on saliva diagnostics, whereas around 50% of clinicians were uncertain about the overall accuracy, despite recognizing the value of saliva tests. Both consumers and clinicians indicated that a chair-side or at-home rapid antigen test (RAT) could enhance the accuracy of saliva testing and address transport issues.

Conclusion

The potential for saliva-based diagnostics for periodontitis shows promising acceptance among both consumers and clinicians. However, further modifications and specifications of the proposed workflow are needed to enhance its viability and accuracy.

Clinical relevance

This study highlights significant consumer interest in saliva diagnostics for periodontitis, indicating a preference for a shift toward personalised, non-invasive diagnostic methods. The mixed responses from clinicians highlight the need for ongoing education and evidence to foster confidence in saliva-based testing, potentially improving early detection and treatment outcomes in periodontal care.
