Comparative Measurement of Tooth Length: Actual vs. Orthopantomography and CBCT-Based Measurements

Abstract

Objective: To compare the reliability of cone beam computed tomography (CBCT) in assessing the tooth length in comparison to orthopantomography (OPG). Material and Methods: Forty patients scheduled for extraction as result of caries or periodontal involvements were randomly selected. Panoramic radiographs and CBCT images were obtained and subsequently patients were subjected for extraction. Teeth with poor prognosis were extracted and stored in 10% formalin. Radiographic teeth measurements were carried out on OPG and CBCT images using a software and the actual tooth length (A-L) measurements were carried out with a digital vernier caliper. The data collected were statistically analyzed for paired "t" test significance of differences and Pearson's correlation at 5% level of confidence. Results: There was significant difference comparing all three actual tooth length (A-L) and CBCT-and OPG-measured tooth lengths. A significant positive correlation was observed among all the measurements. Conclusion: CBCT images exhibited accuracy over panoramic images even though the measurements are still significantly different from actual anatomical tooth lengths.

Mandibular assessment of panoramic radiographs for sex identification

“…The precision of digital PR in delivering anatomical measurements has made it an invaluable tool in forensic science. Moreover, it offers several advantages, including costeffectiveness, reduced radiation exposure compared to methods such as computed tomography, shorter chair time for patients, and decreased workload for operators, as images can be promptly evaluated after acquisition [10]. Furthermore, PR allows for fine-tuning through contrast and brightness adjustments and offers the option of image enlargement, ensuring a precise and reproducible means of measuring specific points [11].…”

Accuracy of Cone Beam Computed Tomography in the Assessment of Mandibular Molar Furcation Defects

“…Cone-beam computed tomography (CBCT) allows the clinicians to visualize all of the required parameters easily in all dental fields. The utilization CBCT seems to improve the diagnosis and the management in the conventional periodontal treatment and surgeries for the treatment of furcation involved; however, more clinical studies are needed to support this conclusion [13][14][15][16][17][18]. Therefore, the current study is designed to evaluate the accuracy of CBCT in the assessment of mandibular molar furcation defects.…”
