Eye-tracking metrics to compare visual attention in prosthodontic preclinical evaluations.

ABSTRACT: The study aimed to evaluate gaze behavior during tooth preparation assessments by analyzing and comparing eye-tracking metrics between novice and expert groups. Thirty-five participants, divided into novices (n = 18, mean age = 22.9 ± 1.5 years) and experts (n = 17, mean age = 44.3 ± 13.1 years), were recruited for this observational study. The novice group consisted of third-year dental students, while the expert group comprised licensed dentists with an average of 18.9 ± 12.7 years of clinical experience. Eye-tracking metrics, including total duration of fixation (TDF), number of fixations (NF), time to first fixation (TFF), and pupil size, were measured across different areas of interest (AOIs). The data was analyzed with a two-way repeated measures analysis of variance (ANOVA) model. B
