Objective: Determine the concordance and relationship between periodontal clinical attachment level and radiographic examination in patients with chronic periodontitis. Methods: Cross-sectional study of 135 participants over 16 years, randomly selected, diagnosed with chronic periodontitis. Of which 352 were obtained in 1292 periapical interproximal sites. It was measured the height of the ridge with a millimeter ruler. Furthermore, were examined the type of defect, the continuity of the lamina dura and widening of the periodontal ligament space. The data were analyzed using measures of central tendency and dispersion. To quantify the correlation test was used for Kappa and relationships were used odds ratios with confidence intervals of 95%, and was used to establish significance Chi-square test assuming a decision limit of 0.05. Results: There was a statistically significant relationship between attachment levels 4, 5 and 6 mm and radiographic bone loss. For the other relationships were not statistically significant. Regarding the type of defect, the horizontal pattern loss was the most common with 23% of the sites examined. Conclusion: For the diagnosis of chronic periodontitis is not enough with the assessment of radiographic examination, because attachment levels 1, 2 and 3 mm bone loss occurs not visible. It is clear that using only this method of diagnosis would increase the false negative underreported disease.
