Technical Quality of Root Fillings Performed by Undergraduate Students: A Radiographic Study

Table 2

Length and density of root canal fillings in straight and curved canals.

	Root canal	Length			Density
		Adequate	Overextended	Short	Adequate	Inadequate
Straight	411 (72.74%)	387 (94.16%)*	7 (1.70%)	17 (4.14%)	379 (92.21%)^†	32 (7.99%)
Curved	154 (27.26%)	120 (77.92%)	3 (1.95%)	31 (20.13%)	144 (93.51%)	10 (6.49%)
Total	565 (100%)	507 (89.73%)	10 (1.77%)	48 (8.50%)	523 (92.57%)	42 (7.43%)

∗Statistically significant difference (𝑃<0.01) between adequate lengths of root canal fillings in straight and curved root canals.
^†No statistically significant difference (𝑃>0.05) between adequate densities of root canal fillings in straight and curved root canals.
