Comparative study between digital and manual cephalometry with digital radiographs

Resumen

Objective: The objective of this study was to compare the reliability of the measures of the computerized cephalometric program Nemoceph Nx, with the tracing done manually with digital lateral skull radiographs to 91% printed on photographic paper. Methods: We used 20 digital lateral radiographs of the skull taken from 20 patients with a Sirona brand direct digital ORTHOPHOS XG Plus cephalostat. Once the captured image was transferred directly to the same computer program (Nemoceph Nx) it was also printed for the tracing of 12 measures: 6 linear a nd 6 angular. Results: A comparison between the manual tracing and the program Nemoceph Nx measures was performed and we found no statistically signifi cant differences (p > 0.05) between the two groups. Conclusions: The results show an excellent reliability for everyday use of the NX Nemoceph program for diagnosis using cephalometric digital radiography.

Key words: Cephalometric software, digital radiography, digital cephalometry.
