The aim of this study was compared two direct digital devices with the periapical radiograph and with the real measure evaluated by a digital caliper  being analyzed the results how to the degree of allegiance of the measurement. Twenty uniroot permanent teeth were utilized to realize the digital caliper  measurement. After that, the teeth were included in nº7 wax utility and conventional periapical and digital radiographs were taken. The X-Ray machine used was the 765 DC^® (Gendex^® -Il- USA) with 65 kVp, 7mA, 30cm distance focus- film and exposure time to digital and conventional periapical of the 0.02s and 0,16s respectively. The direct digital devices used were the RVG^® (Trophy,Vallée- France) and the Visualix^® (Gendex^® -Il- USA). The measurement of the teeth were realized using the own measure tool of the digitals devices software. To conventional technique, the digital caliper  were used to realize the measurement. The values obtained were submitted to Tukey test and t paread test with the Bonferroni correction. The results showed possess statistically significant difference. However, it’s possible to conclude that the direct digital devices and the conventional method are trustworthily in measurement in the dental clinical pratice, being the Visualix^® showed the best results.
