Resumo: The objective of this study was to evaluate the accuracy and reproducibility of photogrammetric principles and techniques over periapical radiographic images. Twelve stereoscopic radiographic pairs were obtained by means of an Auxiliary Aiming Device (AAD) fixed to a human jaw. The best angle of convergence to allow stereoscopy was verified to be 20°. The radiograph images were digitalized on a photogrammetric scanner and the data transferred to a computer memory. For each pair of images, ten readings of the coordinates of a same point were recorded. The precision obtained for the measurements of X, Y, Z coordinates were respectively 3 µm, 3 µm and 18 µm. The reproducibility of the experiment was possible due to the high rigidity and stability of the device created to hold the X-ray instrument in the right position. The method shows to be high accurate for radiodiagnosis in three-dimensional periapical radiographic images.
