Over a dozen tools emulate measurements from protractor, ruler, and caliper measurements, completely automated to reduce time and effort. After the tracings were done on the lateral cephalogram, the following hard tissue landmarks were identified: S (sella turcica), N (nasion), A (subspinale), B (supramentale), Gn (gnathion), and Go (gonion). Materials and Methods: The conventional lateral cephalograms of twenty participants were obtained. Six hard tissue landmarks were identified, and Steiners analysis was carried out. The radiographs were manually traced, and the readings were recorded. Following this, the radiographs were uploaded in the FACAD digital software for digital tracing. Results: SNA, SNB, lower incisor to NB angle, and linear values show statistically significant differences. Conclusion: The results show a statistical difference between manual and digital tracing. The variation lies in the difference in identification of the hard tissue landmarks. Comparison of cephalometric readings between manual tracing and digital software tracing: A pilot study. Cephalometric Tracing Software Serial Online 2016Int J Orthod Rehabil serial online 2016 cited 2020 Aug 31;7:135-8. The manual method was previously the only available method used for achieving and procuring cephalometric tracings and angular and linear measurements required for their interpretation. The main drawback of this method was in the fact that it was more time-consuming, particularly for orthodontists and was subjected to a high degree of operator error. Although the radiographic film is quite stable, it tends to deteriorate over time which leads to a loss in the quality of the radiographic image. With the rapid growth of computer radiography, digital tracing has slowly replaced the manual tracing methods. The concept of the digital radiographic image refers to the image captured from X-rays incidence and shown on the computer. It can be achieved by two different ways: through systems with or without the adoption of radiographic films. These methods can also be called indirect or direct method. In the direct method, the image is acquired directly through a charged coupled device eliminating the use of radiographic film and darkroom. In the indirect method, also called hybrid system, a conventional radiography is registered by a video camera or scanner and transformed into digital format in a computer through a software program. According to manufacturers, it also provides approximately 80 radiation dose reduction compared to conventional radiographies. Previous studies have shown that computer-aided cephalometric analysis does not introduce more measurement error as long as the landmarks are identified manually. Therefore, manually identifying landmarks on a screen displayed digital images for cephalometric analysis is still a better alternative. However, there are still some orthodontists who prefer manual method than the use of computers. One of the reasons is the inevitability of the financial investments in the software and the belief that the conventional method is the adequate technique. For digital cephalometry to develop as a better clinical tool in orthodontics, the cephalometric analysis represented by often used linear and angular measurements must be as comparable and reliable as it is on a conventional radiographic film. Hence, the present study was carried out to find which method is superior in terms of accuracy and adequacy. Materials and Methods Twenty pretreatment cephalometric radiographs Figure 1 of patients were chosen based on the following criteria: Good quality radiographs with no obstruction in identification of anatomical landmarks No previous history of orthodontic treatment Patient biting in centric occlusion. Figure 1: Preoperative lateral cephalogram Click here to view The cephalometric analysis was done by the following two methods: 1. Manual 2. Digital. Manual method All the lateral cephalograms were traced using a sheet of acetate tracing paper. The tracings were done on a view box with the tracing paper securely positioned over the radiograph with a masking tape.
