Efficacy of a Newly Designed Cephalometric Analysis Software for McNamara Analysis in Comparison
2016
Objectives: Cephalometric norms of McNamara analysis have been studied in various populations due to their optimal efficiency. Dolphin cephalometric software greatly en-hances the conduction of this analysis for orthodontic measurements. However, Dolphin is very expensive and cannot be afforded by many clinicians in developing countries. A suit-able alternative software program in Farsi/English will greatly help Farsi speaking clini-cians. The present study aimed to develop an affordable Iranian cephalometric analysis software program and compare it with Dolphin, the standard software available on the market for cephalometric analysis. Materials and Methods: In this diagnostic, descriptive study, 150 lateral cephalograms of normal occlusion individuals were selected in Mashhad and Qazvin, two major cities of Iran mainly populated with Fars ethnicity, the main Iranian ethnic group. After tracing the cephalograms, the McNamara analysis standards were measured both with Dolphin and

Assessment of the Reliability of Automatic Cephalometric Analysis Software
International Journal of Mechanical Engineering and Robotics Research
The aim of this study was to evaluate and compare the reliability of a fully automatic cephalometric analysis software with manual cephalometric tracing. The lateral cephalograms of 108 orthodontic patients were selected. Eight linear (Pg-NB, Co-A, Co-Gn, U1-NA, L1-NB, Lower lip to E-plane, S-Go, and N-Me) and 9 angular (NS-Ba, SNA, SNB, NS-MP, FH-FO, U1-NA, L1-NB, L1-MP, and U1-L1) measurements were used in this study. The cephalometric analyses were performed by both manual method and automatic software. The differences between two methods were compared by paired t-test with p<0.05. Analysis of interexaminer calibration of the measurement revealed a high reliability. The result showed that there were statistically significant differences (p<0.05) in 13/17 parameters between the two methods, which consisted of 6 linear parameters (Pg-NB, Co-A, Co-Gn, U1-NA, L1-NB, and Lower lip to E-plane) and 7 angular parameters (SNA, NS-MP, FH-FO, U1-NA, L1-NB, L1-MP, and U1-L1). Only 4 parameters (NS-Ba, SNB, S-Go, and N-Me) did not show any significant differences. It is summarized that 76.47% (13/17 parameters) of cephalometric measurements performed automatically by the dental imaging software showed statistically significant differences when compared with the manual method. The automatic software could not reliably locate all cephalometric landmarks. Hence, the clinicians should not rely on the fully automatic analysis mode since the algorithm of the software still needs improvement for the higher accuracy in locating the cephalometric landmarks. Thus, to obtain accurate results, manual adjustments to the automatically located cephalometric landmarks are recommended.

Cephalometric radiography is an indispensable tool in orthodontics for studying growth and development of dentofacial skeleton, diagnosis, treatment planning, and evaluating treatment results. [1-4] Conventionally, manual tracing is considered "Gold standard" in cephalometric analysis. However, it is cumbersome, time consuming and can be associated with various errors. These errors can occur due to improper tracing, inaccurate landmark identification, measurement and calculation errors in addition to errors occurring due to human fatigue. [3-8] With recent technological advances and increasing use of computers in the field of orthodontics cephalometric analysis using computerized cephalometric analysis softwares have gained popularity. These softwares have eliminated various errors associated with manual tracings and are less time consuming. Another big advantage of using computerized cephalometry is that multiple analyses can be done in a very short period. [9-14] Over the years, various softwares have been developed which claim to be as reliable and accurate if not more than manual tracings. Most of the studies which evaluated the reliability
Evaluation of the reliability of computerized profile cephalometric analysis
Brazilian Dental Journal, 2002
The use of computers as an auxiliary instrument for case evaluation and procedures in health sciences is not new, and their advantages are well known. A growing number of orthodontists are using computerized systems for cephalometric analysis. Thus, this study evaluated the reliability of both computerized and manual methods used for creating profile cephalograms. Fifty profile radiographs were selected from the files of the Post-Graduate Course in Orthodontics at the Dental School of the Federal University of Rio de Janeiro. The good quality of the material was the only necessary requirement for selection. Results were submitted to the interclass correlation coefficient and a reliable similarity between cephalometric data obtained through both evaluated methods was found. However, the clinical utilization of computerized cephalometric analysis is not absolutely reliable.

Introduction: Cephalometry is an important tool in orthodontic diagnosis, treatment planning, for evaluation of treatment results and prediction of growth. With standardized radiographs, the orientation of various anatomical structures can be studied using angular and linear measurements. Hand traced cephalometric analysis on traditional radiographic films has been the gold standard for analyzing a cephalometric radiograph for the past few decades. Despite its widespread use in orthodontics, the technique is time-consuming including risks of error during hand tracing, landmark identification, and measurements. Aim: The aim of this study was to compare the accuracy and reliability of cephalometric measurements made on digital software (Dolphin imaging and management solution) with that of hand traced conventional methods. Materials and Methods: A total of 52 cephalometric digital radiographs of patients within the age group of 18-25 years were selected. A total of 10 angular and 5 linear measurements were obtained from the radiographs using both the manual and digital technique. Results: Statistical analyses were performed using analysis of variance and post hoc Bonferroni tests. Angular measurements upper incisor to palatal plane, angle of convexity and among linear N' to Me', N to ANS showed variation in measurement but were found to be statistically insignificant. Conclusion: Measurements obtained from both the softwares on digital cephalograms were found to be reproducible and comparable to the manual method done on its hard copy.
Comparison of two three-dimensional cephalometric analysis computer software
Journal of Orthodontic Science, 2014
Background: Three-dimensional cephalometric analyses are getting more attraction in orthodontics. The aim of this study was to compare two softwares to evaluate three-dimensional cephalometric analyses of orthodontic treatment outcomes. Materials and Methods: Twenty cone beam computed tomography images were obtained using i-CAT ® imaging system from patient's records as part of their regular orthodontic records. The images were analyzed using InVivoDental5.0 (Anatomage Inc.) and 3DCeph™ (University of Illinois at Chicago, Chicago, IL, USA) software. Before and after orthodontic treatments data were analyzed using t-test. Results: Reliability test using interclass correlation coefficient was stronger for InVivoDental5.0 (0.83-0.98) compared with 3DCeph™ (0.51-0.90). Paired t-test comparison of the two softwares shows no statistical significant difference in the measurements made in the two softwares. Conclusions: InVivoDental5.0 measurements are more reproducible and user friendly when compared to 3DCeph™. No statistical difference between the two softwares in linear or angular measurements. 3DCeph™ is more time-consuming in performing three-dimensional analysis compared with InVivoDental5.0. Clinical Implications: InVivoDental5.0 utilizes less time in performing three-dimensional cephalometric measurements compared to 3DCeph™ system.
