Mixed reality (MR), encompassing augmented reality (AR) and virtual reality (VR) technologies, is an emerging tool in clinical dentistry that enables digital information to be displayed directly within the clinician’s field of view. Modern dental practice relies heavily on electronic health records, radiographic imaging, and computer-assisted diagnostic and surgical systems, often requiring clinicians to divert attention away from the operative field. These interruptions can disrupt workflow and increase cognitive load. This study aimed to quantify computer dependence across common general dentistry and oral surgery procedures and to evaluate which clinical discipline may benefit most from MR integration into dental loupes. A retrospective observational analysis was conducted on fifty patients treated by a single general dentist, with ten patients included in each procedure category: Extraction(s), Root Canal Treatment(s), Crown(s), Filling(s), and Prophylaxis. An additional fifty patients were treated by two oral surgeons across six procedure categories, with ten patients per category except for implant procedures, which included five patients each: Surgical Extraction(s) with IV Sedation, Implant without Assisted Reality Glasses, Implant with Assisted Reality Glasses, Bone Graft with IV Sedation, Bone Graft with Local Anesthesia, and Biopsy. Computer usage was quantified as seconds per interaction with digital devices during active treatment. A two-sample t-test demonstrated a statistically significant difference in computer usage between general dentistry and oral surgery procedures (p < 0.001), with oral surgery exhibiting more frequent digital interactions and greater computer dependence. One-way ANOVA tests conducted independently within each discipline revealed significant variation in computer usage among procedure types. These findings suggest that targeted MR integration may be particularly beneficial in oral surgery workflows, where frequent consultation of digital systems is essential. Prioritizing MR and assisted reality technologies in high-dependence procedures may reduce attention shifts, lower cognitive load, and enhance clinical efficiency.
