Table 8 Dental anxiety scale (DAS) score of the participating students (n = 120)

Variable	Outcome	DAS Score	Sig.
Gender	Female	6.17 ± 1.57	0.030
	Male	5.53 ± 1.56
Chronic illness	Yes	6.17 ± 1.40	0.510
	No	5.94 ± 1.61
Medical treatment	Yes	6.33 ± 1.56	0.336
	No	5.93 ± 1.59
Smoking	Yes	5.50 ± 0.93	0.534
	No	6.00 ± 1.62
Operator	Student	5.84 ± 1.50	0.454
	Dentist	6.10 ± 1.68
Injection technique	Infiltration	6.01 ± 1.51	0.669
	Nerve Block	5.84 ± 1.62
Injection method	Computer-controlled	5.97 ± 1.59	1.000
	Conventional	5.97 ± 1.59

Bold value is significant ≤ 0.05
Mann-Whitney (U) test was used was a significance level (Sig.) ≤ 0.05
Using Spearman’s rank coefficient, the bivariate correlation revealed that VAS on puncture and VAS during injection had a moderate correlation (ρ = 0.449; Sig. < 0.001). On the other hand, the total DAS score was not correlated with either VAS on puncture or VAS during the injection (Table 9)
