“…Various research methods have been used to examine root canal morphologies, such as decalcifying and ink dye [ 5 , 6 , 7 , 8 , 9 , 10 , 42 ], radiographic [ 15 ], cross-sectional [ 12 ], CBCT imaging [ 6 , 13 , 14 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ], and micro-CT imaging [ 34 , 37 ]. While the sectioning method requires the destruction of the specimens and, due to the thickness of the slices, an exact reconstruction of the canal anatomy is not possible, radiographic examination is a largely subjective method that is difficult to interpret.…”
