Evaluation of the Reliability of an Android-based Application OneCeph with Computerized Cephalometric Program Nemoceph: A Comparative Study

Abstract

Aim: To assess the reliability of the OneCeph application in comparison with the Nemoceph cephalometric analysis program in determining five angular and five linear parameters. Materials and methods: A total of 54 pretreatment lateral cephalometric radiographs were obtained using a digital cephalometer (Gendex Orthoralix 9200 developmental defects of enamel (DDE), Gendex Dental Systems) were taken. After the identification of landmarks, five angular and five linear measurements were recorded, and cephalometric analysis was performed using computer-based software Nemoceph, and an android-based application OneCeph, respectively. The reliability (intraexaminer error) was evaluated using Spearman’s correlation. Results: Spearman’s correlation coefficient of angular and linear parameters for each method was r ≥ 0.8. A statistically significant difference was found between Nemoceph and OneCeph for two parameters, namely sella, nasion and point A (SNA) (p = 0.049) and upper incisor to nasion-point A (UI-NA) (mm) (p = 0.03), respectively. Conclusion: Using five angular and five linear measurements, the reliability of OneCeph was compared with the Nemoceph cephalometric analysis program, and the difference was found to be clinically insignificant for most of the parameters. Clinical significance: The android-based cephalometric application OneCeph seems to be reliable and could be considered as an alternative to Nemoceph. Thus, it fulfills the need for instant cephalometric values anytime and anywhere, especially in clinical practice.
