Sensors and wearables as key to monitor oral health: A scoping review

The integration of intraoral sensors and wearables in digital dentistry offers potential advancements in personalized oral healthcare. This scoping review aims to evaluate the types of technologies and parameters investigated for continuous oral monitoring, assess their clinical relevance, and explore the future outlook of these innovations in dentistry. A scoping review was conducted in accordance with the PRISMA-ScR guidelines. Clinical trials in English involving intraoral sensors and wearables, were included. Studies exclusively of extraoral wearables were excluded. A comprehensive literature search was performed in PubMed and Web of Science, selecting clinical trials relevant to oral health, biomarker monitoring, and personalized dentistry. The scoping review identified a total of 656 titles, while 11 clinical trials met the inclusion criteria, published between 2020-2024. The majority of the trials focused on oral function, endodontics, and periodontology. The most frequent monitoring parameters were bite force, pressure application, and temperature changes. Key findings indicate that intraoral sensors can monitor mechanical and biological parameters, contributing to more personalized and preventive dental care. There is a growing interest in wearable and sensor technologies for oral health monitoring. Intraoral sensor technologies hold significant potential for improving personalized oral healthcare. The current evidence supports their potential for improving clinical outcomes through continuous monitoring and personalized interventions. Future research should focus on data standardization, patient compliance, and patient satisfaction with personalized approaches improving oral and general health. • Intraoral sensors and wearables enabled continuous monitoring of oral health. • Key dental disciplines explored included oral function, periodontology, and endodontics. • The current evidence supports their potential for improving clinical outcomes through continuous monitoring and personalized interventions. • Research is needed on data standardization, patient compliance, and patient satisfaction.
