Comparison of perceived pain and patients’ satisfaction with traditional local anesthesia and single tooth anesthesia: A randomized clinical trial

Table 2 Perceived pain among the patients of infiltration and single tooth anesthesia group using Wong-Baker FACES pain scale

Perceived pain	Patient group	Mean ± SD before	Mean ± SD After / during	Mean difference	P value
Before anesthesia vs During anesthesia	Infiltration	1.35 ± 1.79	1.2 ± 1.5	0.15	0.68
	STA	1.5 ± 1.95	1.02 ± 1.4	0.48	0.15
Before anesthesia vs After anesthesia	Infiltration	1.35 ± 1.79	0.32 ± 0.53	1.03	0.001
	STA	1.5 ± 1.95	0.15 ± 0.66	1.35	< 0.001
Before anesthesia vs During procedure	Infiltration	1.35 ± 1.79	0.9 ± 1.35	0.45	0.18
	STA	1.5 ± 1.95	0.22 ± 0.77	1.28	< 0.001

STA: Single tooth anesthesia.
