Descriptive values (median, iqr: inter quartile range, z-value, p-value, N) for group comparisons (Wilcoxon signed-rank tests) of dental anxiety measured with the DAS based on Sex (male/female), Age (years), Partners (yes/no), Life satisfaction (high/low), Annual dentist appointments (≥ 2/<2), Daily frequency of tooth brushing (≥ 2/<2), G-Score (healthy/unhealthy), Perceived condition of health (good/poor), Perceived influence over health (high/low), indication for depression measured with PHQ-2 (yes/no), indication for anxiety measured with GAD-2 (yes/no), and social support measured with OSSS-3 (moderate to high/low).
