Comparative Evaluation of Apically Extruded Debris during Pulpectomy Procedure in Primary Molar Teeth Using Two Different Rotary Systems and Hand Files: An In Vitro Study

Table 1

Mean, standard deviation, standard error, confidence interval, and value for weight of extruded debris in groups A, B, and C, respectively.

Group	n	Mean	Standard deviation	Standard error	95% confidence interval for mean		value
					Lower bound	Upper bound
Group A	20	0.0009614	0.000500	0.000111	0.000727	0.001195	0.001
Group B	20	0.0011119	0.000705	0.000157	0.000781	0.001442
Group C	20	0.0018902	0.000850	0.000190	0.001492	0.002288

Note. Level of significance set at . The bold value suggests that the result was significant between the three groups. It suggests that the result was significant as p value is less than 0.005.
