Difference of Morphometric Value of Microtomography according to Section Plane Histomorphometry
Objective: The aim of this study was to evaluate the difference of morphometric value from microcomputed tomography (MCT) according to the section plane, and to compare conventional histomorphometric data from alveolar ridge preservation in canine model. Method: Mandibular second and fourth premolars of four beagle dogs were extracted and porcine hydroxyapatite graft + polytetrafluoroethylene (PTFE) membranes were applied with primary wound closure. After 8 weeks of healing, animals were euthanized for specimen preparation for both MCT and histomorphometry. For MCT data, section plane was set to the histomorphometric specimen as close as possible, and then the plane was moved by 50 µm offsets and 10 degree rotations. The area occupied by bone and soft tissue were analyzed and compared. Result: The comparison of measured value from between histomorphometry and MCT in a similar plane showed minimum differences. However, the differences of value from MCT image from different plane were very significant. Conclusion: Within the limit of the present study, there can occur significant differences when the specimens are analyzed in the different planes with small offsets or angles. In this regards, it can be concluded that monoplane histomorphometric analysis could have severe selection errors.
