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

Table 3

Length and density of root fillings by canal location (maxilla/mandible).

Canal location	Total	Length			Density
		Adequate	Overextended	Short	Adequate	Inadequate
Maxillary canals	316 (55.93%)	293 (92.72%)*	4 (1.26%)	19 (6.02%)	292 (92.40%)^†	24 (7.60%)
Mandibular canals	249 (44.07%)	214 (85.94%)	6 (2.41%)	29 (11.65%)	231 (92.77%)	18 (7.23%)
Total	565 (100%)	507 (89.7%)	10 (1.8%)	48 (8.5%)	523 (92.6%)	42 (7.4%)

∗Statistically significant difference (𝑃<0.05) between adequate lengths of root canal fillings in maxillary and mandibular teeth.
^†No statistically significant difference (𝑃>0.05) between adequate density of root canal fillings in maxillary and mandibular teeth.
