Time-Dependent Effect of Chitosan Nanoparticles as Final Irrigation on the Apical Sealing Ability and Push-Out Bond Strength of Root Canal Obturation

Table 1

Mean and standard deviation of the sealing ability of root canal obturation (in mm).

Final irrigation	Application time	Mean ± standard deviation
17% EDTA	1	5.17 ± 1.35^a
	3	2.06 ± 0.43^b
0.5% chitosan nanoparticle	1	4.88 ± 1.62^a
	3	1.97 ± 0.61^b

Different letters indicate that there were statistically significant differences.
