Abstract

Introduction: The purpose of this study was to evaluate the accuracy of cephalometric measurements obtained from digital tracing software compared with equivalent hand traced measurements to determine the more accurate and useful method.Materials & Methods: Digital and analogue radiographic images of 30 orthodontic patients were obtained through SANDWICH TECHNIQUE (a conventional radiographic film and a digital image are produced simultaneously). Fifteen cephalometric landmarks were identified and 10 linear and angular measurements calculated, both manually and with digital tracing software. Measurement errors were assessed for each method by duplicating measurements of 15 randomly selected radiographs using Pearson’s correlation coefficient. A paired t- test was used to detect differences between the manual and digital methods.Results: Differences between the two methods for SNA, U1-L1and Wit’s appraisal were statistically significant (P<0.05). In error measurements, an overall greater variability in the digital cephalometric measurements was found.Conclusion: The two tracing methods provided similar clinical results; therefore, efficient digital cephalometric software could be reliably chosen as a routine diagnostic tool due to its advantages (lower exposure to X-ray, image development bypass, image quality enhancement through computer).
