Comparisons between mean onset time of anaesthesia for patients in anterior, middle and posterior teeth groups

Groups		Number of patients n	Mean (SD) (min)	ANOVAt-test (df=89)	P
	Anterior teeth	30	3.73 (3.10)
Anesthesia onset time	Middle teeth	23	4.96 (3.90)	0.808	0.449
	Posterior teeth	39	4.36 (3.52)

Bold value is not statistically significant because P value > 0.05
