Intra- and Inter-operator Reliability of Cephalometric Landmark Identification

Pages : 84
Book Description
The purpose of this study was to compare examiner reliability of cephalometric measurements from cone beam computed tomography (CBCT) and conventional digital cephalograms. Three imaging modalities were compared: CBCT using maximum intensity projection and ray-sum algorithms, and conventional digital cephalograms. Blinded examiners were calibrated, and intra- and inter-examiner reliability were assessed. Data were collected on a convenience sample of seven subjects. Examiners obtained linear and angular measures on each of the subjects' images, and rater consistency among the three methods were assessed using repeated measures analysis of variance of intraclass correlation coefficient ratios. A statistically significantly greater level of consistency for linear measurements was seen with the CBCT images. For the conventional digital images, linear measurements showed less consistency than angular measurements. This statistical significance unlikely correlates to a clinical significance. For orthodontic diagnosis, treatment planning, and treatment evaluation, CBCT generated cephalograms are equally effective to conventional digital cephalograms.

An Atlas on Cephalometric Landmarks
Author: Basavaraj Phulari
Publisher: JP Medical Ltd
ISBN: 9350903245
Category : Medical
Languages : en
Pages : 233
Book Description
Cephalometry is an imaging technique used in orthodontics to measure the size and spatial relationships of the head, jaws and teeth, making use of landmarks or points on the skull. It is used for diagnosis, treatment planning and evaluating dentofacial changes during treatment. This book focuses on understanding the different cephalometric landmarks/points. Beginning with an introduction to the technique and classification of the landmarks, the following chapters explain each point in detail, by section of the head – cranial bones, facial bones and dentition, soft tissue, cervical bones and pharynx. The final sections discuss the different types of imaging used to trace cephalometric landmarks and their applications. Key points Presents technique of cephalometry to diagnose, and plan and evaluate treatment in orthodontics Describes every landmark by section of the head, including abbreviation, definition and applications Compares alternative radiological imaging techniques Includes more than 350 colour images and illustrations

The Reliability of Cephalometric Tracing Using AI

Book Description
Introduction: The objective of this study is to compare the difference between manual cephalometric analysis and automatic analysis by artificial intelligence to confirm the reliability of the latter. Our research hypothesis is that the manual technique is the most reliable of the methods and is still considered the gold standard. Method: A total of 99 lateral cephalometric radiographs were collected in this study. Manual technique (MT) and automatic localization by artificial intelligence (AI) tracings were performed for all radiographs. The localization of 29 commonly used landmarks were compared between both groups. Mean radial error (MRE) and a successful detection rate (SDR) of 2mm were used to compare both groups. AudaxCeph software version 6.2.57.4225 (Audax d.o.o., Ljubljana, Slovenia) was used for both manual and AI analysis. Results: The MRE and SDR for the inter-examinator reliability test were 0.87 ± 0.61mm and 95% respectively. For the comparison between the manual technique MT and landmarking with artificial intelligence AI, the MRE and SDR for all landmarks were 1.48 ± 1.42mm and 78% respectively. When dental landmarks are excluded, the MRE decreases to 1.33 ± 1.39mm and the SDR increases to 84%. When only hard tissue landmarks are included (excluding soft tissue and dental points) the MRE decreases further to 1.25 ± 1.09mm and the SDR increases to 85%. When only soft tissue landmarks are included the MRE increases to 1.68 ± 1.89mm and the SDR decreases to 78%. Conclusion: The software performed similarly to what was previously reported in literature for software that use analogous modeling framework. Comparing the software's landmarking to manual landmarking our results reveal that the manual landmarking resulted in higher accuracy. The software operated very well for hard tissue points, but its accuracy went down for soft and dental tissue. Our conclusion is this technology shows great promise for application in clinical settings under the doctor's supervision.
