Multidimensional Analysis of Curved Root Canal Preparation Using Continuous or Reciprocating Nickel-titanium Instruments

Table 4: Median, minimum and maximum values of T(BL) at different points in root canal (mm).

–	2 mm Short of Apex	3 mm Short of Apex	4 mm Short of Apex	2 mm Below Furcation	3 mm Below Furcation	4 mm Below Furcation
Median	0.050^a	0.050^a	0.070^a	0.070^a	0.060^a	0.060^a
Minimum	0.000	0.000	0.000	0.000	0.000	0.000
Maximum	0.220	0.220	0.430	0.210	0.270	0.270

*In each column, medians with a common superscript letter are not statistically different (p<0.05).
