Aim: This study aimed to compare between patient's and clinician's interpretations of dental occlusion in eccentric mandibular positions when T-Scan III was used as a standard device. Materials and methods: Forty-three participants were trained to slide their jaw to the eccentric mandibular positions (right excursion, left excursion, and protrusion). The eccentric positions were determined at the edge-to-edge contact of anterior teeth in protrusion, the edge-to-edge contact opposing canines, and/or contact of buccal cusps of the opposing premolars in the working position. Contacting pairs of teeth were recorded based on the patient's perception, clinician's interpretation using traditional occlusal indicators, and a digital occlusal indicator; T-Scan III. Weighted kappa was used to determine the correlation of dental occlusion obtained from the patient's perception and clinician's interpretation compared to T-Scan III. Results: The highest correlation was in protrusion (substantial agreement; κω = 0.661 for the patient group and 0.772 for clinician group) followed by left and right excursion (moderate agreement; the left excursion, κω = 0.569 in both groups; the right excursion, κω = 0.430 for the patient group and 0.545 for clinician group), respectively. Conclusion: In a clinical situation, the interpretation of dental occlusion in eccentric mandibular positions acquired from a clinician is more dependable than information from patients. Clinical significance: Dental occlusion evaluated by a clinician is more compatible with T-Scan III than that by patients.
