Table 1_Prevalence of color vision deficiency among Saudi dentists and its effect on shade selection: a cross-sectional study.docx

Color vision deficiency (CVD) may impair this ability, yet data on its prevalence and clinical impact among dentists in Saudi Arabia are limited. This study aimed to determine the prevalence of CVD and its association with shade-matching accuracy.</p>Methodology<p>This cross-sectional study included 150 dental students, interns, general dentists, and specialists.

Color vision was assessed using the Ishihara test and categorized as normal, borderline, or red–green CVD. Shade-matching accuracy was evaluated using the VITA Classical Shade Guide under standardized lighting. Group differences were analysed using the Kruskal–Wallis test with post-hoc Wilcoxon rank-sum tests and Holm adjustment.</p>Results<p>Normal color vision was observed in 78.7% of participants, 6.0% had red–green CVD, and 15.3% showed borderline findings.
