“…A study to examine the potential and accuracy of micro-CT for imaging of filled root canals showed it to be a highly accurate and nondestructive method for the evaluation of root canal fillings and their constituents. Qualitative and quantitative correlation between histological and micro-CT examination of root canal fillings was high (42,44). However, note that micro-CT remains a research tool and cannot be employed for human imaging in vivo.…”

“…Lammertyn et al (22) used a sectioning method and profile projector to assess the furcation grooves in the buccal roots of MFPs. This approach is complicated, time consuming, and can introduce artifacts and distortion of internal tooth anatomy (23). Although the authors produced three horizontal slices (2 mm from the furcation, 2 mm from the anatomic apex, and the third slice equidistant between the first and second slices), they still could not provide a complete picture of the furcation grooves.…”

SummaryObjectives. The aims of this study were to conduct a morphometric analysis on the buccal furcation grooves in freshly extracted bifurcated maxillary first premolars (MFPs) and to correlate all anatomical measurements using microcomputed tomography. Materials and Methods. Twenty-three human MFPs with bifurcated canals were selected for this study. The specimens were analyzed with microcomputed tomography. The length, the beginning, and the ending of the grooves were measured. The minimum cross-sectional canal wall thickness in the grooves was located, and the width of the dentin thickness was calculated. All measurements were recorded and statistically analyzed. Results. The concavity of the grooves begins before the bifurcation site in 9/23 samples and after the bifurcation in 56.5% of samples. The groove length varied between 1.1-9 mm; the cross-sectional area with minimum palatal dentin thickness was 0.78±0.14 mm, which was located at a mean distance of 7.1 mm from the cementoenamel junction (CEJ) and 1.38 mm from the furcation. Conclusions. The presence of the furcation grooves in the palatal aspects of the buccal roots of the MFPs was 100%. The length, depth, location, and width of the dentin thickness of the grooves varied in relation to tooth length, bifurcation, and CEJ. These parameters should be taken into consideration before any endodontic or restorative procedures are performed. Reducing dentin width too vigorously by intracanal instrumentation can predispose to vertical root fractures or perforations; if a post cannot be avoided, it should not extend 6.5 mm from the CEJ.

“…Microcomputed tomography scanning as a nondestructive method and with the ability to view three-dimensional structures has had promising applications in endodontics (16,17). It has been used to investigate the presence of anatomic structures (18,19) and to evaluate the centering ability and the efficiency of rotary systems and hand files when used for root canal preparation (20 -26). However, to date, there is no report on the use of microcomputed tomography scanning to assess changes of root canal space after the removal of fractured files.…”
