RESUMO
The aim of this study was to evaluate three radiographys techniques: periapical radiography, panoramic and digital radiography, about diagnostic accuracy of artificially produced bony lesions in human jaw dry. The periapical diseases were done using burs numbers 6, 8 and 10 thus allowing the lesions diameter to incresing according to burs size. Therefore, the study was dividided in four phases: phase 1 without periapical disease, phase 2 periapical disease made by bur number 6, phase 3 periapical disease made by bur number 8, phase 4 periapical disease made by bur number 10 and phase 5 periapical disease touchs junction area of the cortex. The phases were in four regions in the jaw, anterior, canine, premolar and molar. The radiographies were evaluated by four oral radiologists observers. The results showed that in the anterior region there was a significant statistically difference only at phase 2, that is the lesion was produced with bur 6, the digital radiography was more successfull and it was also observed in the premolar region in the cortical phase. In the molar region there was a false true result during the inicial phase, without lesion. During phase 4 (burn 10 ) and cortical phase there was a statistically significant difference in favor of the panoramic radiography
