Monitoring Occupational Dental Stress Using Apple Watch

* This study will enroll 10 dental students (primary subjects) and up to 200 patients (secondary subjects), approximately 10 special-needs and 10 non-special-needs encounters per student, totaling about 200 treatment sessions. * Students will wear an Apple Watch to continuously monitor heart rate (HR) during routine care. The Apple Watch contains built-in physiological sensors that automatically record heart rate and heart rate variability. These data are stored locally in the Apple Health app on a study-designated iPhone that is assigned for the research and handled solely by the Principal Investigator (PI). No real-time transmission or cloud-based sharing occurs during data recording. No additional apps, accounts, or third-party software are used. At designated intervals, the PI will use the health app's built-in "Export Health Data" function on the study iPhone. This function generates a ZIP file containing an export.xml file with sensor-recorded data. The PI will then upload the ZIP file from the study iPhone directly to a secure, university-approved UI Box Health Data Folder designated for the study. No research account will be set up for this purpose. * A trained observer will record start/stop timepoints of procedure phases (e.g., seating, anesthesia start, operative phase, dismissal) to align with HR signals and will document only minimal patient variables needed for analysis: behavior/cooperation score (e.g., Frankl), sedation status, and broad procedure category (e.g., preventive, restorative, surgical). * Each dental student will complete the Perceived Stress Questionnaire (PSQ) only once at the beginning of the study to stablish a baseline measure of stress. The Questionnaire takes approximately 5 minutes to complete. Students do not need to complete the PSQ for each patient encounter. Student HR data and permitted minimal patient variables will be coded and de-identified, stored securely in UI Box Health Data Folder, and analyzed to compare special-needs vs non-special-needs encounters and to evaluate associations between student HR and the listed patient factors. No additional patient identifiers or PHI will be collected beyond what is specified above.
