The use of Cone Beam Computed Tomography (CBCT) can favor the early diagnosis of apical periodontitis and influence its prognosis and treatment; however, there is no standardization among the indexes that determine the presence of periapical lesions in this radiological technique. For this reason, the aim of this study was to evaluate periapical lesions using three indices on CBCT. The study population consisted of all the CBCT scans performed in a Peruvian radiological center for one year, a non-probabilistic sampling was performed and 36 Cone Beam tomography’s were evaluated with the CBCT-PAI, COPI and CBCT-ERI indexes; the data collected were analyzed statistically and it was determined that the CBCT-PAI index identified 91.7 % periapical lesions; the COPI index, 72.2 % and the CBCT-ERI index, 88.9 %. Likewise, Pearson’s x2 test was applied and a value of p=0.05 was determined. Therefore, it was concluded that the diagnosis of periapical lesions on Cone Beam computed tomography can present similar results when evaluated with any of the CBCT-PAI, COPI or CBCT-ERI indexes.

KEY WORDS: Periapical periodontitis, index, tomography, X-Ray computed.
