Abstract
Objective: To evaluate the intra-examiner and inter-examiner reliability of linear and curvilinear measurements for the complete assessment of implant sites and jaw pathologies using Cone-Beam Computed Tomography (CBCT). Material and Methods: Fifty cone-beam computed tomographic images of patients were retrieved from the archives of Dentomaxillofacial Radiology. CBCT images taken for implant planning and evaluation of intrabony jaw pathologies (benign cyst/tumor) were included. Two expert oral and maxillofacial radiologists analyzed the images independently and made the measurements. The images for implant planning were analyzed for width, the height of the edentulous site, and the qualitative analysis of bone in the region. Jaw pathologies were assessed for linear dimensions and curvilinear measurements. Results: The inter-observer measurement error for implant site analysis ranged from 0.12 to 0.42 mm with almost perfect agreement (ICC: 0.94 to 1). The inter-observer measurement error for jaw pathology was 0.09 to 0.25 mm (ICC: 0.98-1). Curvilinear measurements showed perfect agreement between the observers. The intraobserver reliability for the various parameters used for the assessment of the implant site and jaw pathologies indicated almost perfect agreement. Conclusion: Reliability between the radiologists is high for various measurements on CBCT images taken for implant planning and jaw pathologies.
Highlights
Cone-beam computed tomography (CBCT) imaging provides detailed information by providing a three-dimensional view for the assessment of lesions affecting the maxillofacial region [1]
Reliability between the radiologists is high for various measurements on Cone-Beam Computed Tomography (CBCT) images taken for implant planning and jaw pathologies
This study was done on 50 CBCT images of patients whose images were analyzed for possible implant placement and assessment of the extent of jaw pathologies
Summary
Cone-beam computed tomography (CBCT) imaging provides detailed information by providing a three-dimensional view for the assessment of lesions affecting the maxillofacial region [1]. Measurements made on CBCT images play an important role in clinical situations These include the evaluation of edentulous sites for implant placement, extent and size of cysts, tumors that affect the jaws, measuring airway spaces, and cephalometric analysis. Linear measurements on CBCT images are made for assessing the bone height and width for implant placement along with their distances from adjacent vital structures. These measurements are used for predicting the dimensions of jaw pathologies and envisage their effect on the surrounding structures [7]. The accurate reproducibility and reliability of such measurements become crucial in clinical decision-making and appropriate treatment planning
