Clinical ResearchChange in Periapical Lesion and Adjacent Mucosal Thickening Dimensions One Year after Endodontic Treatment: Volumetric Cone-beam Computed Tomography Assessment
Section snippets
Materials and Methods
Ethical approval for the present study was obtained through Başkent University Ethical Committee, Ankara, Turkey (D-KA15/9). Patients were asked to sign an informed consent before the treatment.
Twenty-one maxillary first molar teeth (11 left and 10 right molars) of 21 patients (14 female and 7 male) with periapical lesion that had local mucosal thickening ≥ 2 mm (defined by Maillet et al [9]) in the vicinity of the affected root and without prior endodontic treatment were treated by an
Results
There was no significant difference between the 2 software (Kodak and 3D DOCTOR) used for the width (P = .857), height (P = .948), and mucosal thickening measurements (maximum mucosal thickening, P = .757; medium mucosal thickening, P = .805; minimum mucosal thickening, P = .803). Therefore, dedicated Kodak software was taken for width, height, and mucosal thickening measurements, and 3D DOCTOR was taken for surface area and volume measurements for the rest of the statistical analyses. We found
Discussion
This study revealed that periapical lesion dimensions along with mucosal thickening in the vicinity of roots with periapical lesions showed a significant reduction when assessed by CBCT. Periapical lesions and sinus mucosal thickening measured in this study had obscure borders; therefore, observer performance, selection of reference points, mouse sensitivity and software capabilities along with segmentation process are all important factors affecting measurement process. In this study, a very
Conclusion
Within the limitations of this study, we found significant reduction in periapical lesion width, lesion height, surface area, and volume in maxillary molar teeth along with adjacent sinus mucosal thickening by using CBCT and specific software 1 year after endodontic treatment. The results of this study are to be considered specific to the one CBCT system and software used under certain settings.
