Title

Correlation between the Periapical Index and Lesion Volume in Cone-beam Computed Tomography Images

Pages

  155-158

Abstract

 Introduction: The study aimed to correlate the Periapical Index (PAI), obtained by way of periapical radiographs, with the volume of chronic periapical lesion, obtained through conebeam computed tomography (CBCT), in the permanent teeth. Methods and Materials: Radiographs and CBCT images were selected from 35 single-rooted permanent teeth, with fully formed apices, with a diagnosis of pulp necrosis and chronic Apical Periodontitis that was radiographically visible. Two independent raters evaluated the radiographs on two separate occasions and classified the periapical lesions in accordance with Ø rstavik’ s PAI. The periapical lesion volume was calculated in the CBCT images. The correlation between the PAI and the lesion volume was calculated using Spearman’ s correlation test. Results: There was a positive, moderate correlation between the PAI and the volume (rs=0. 596; P<0. 001) where rs 2 is equal to 0. 355, showing that only 35% of the PAI variation was dependent upon the variation in periapical lesion volume. Conclusion: The radiographic evaluation of the periapical lesion does not reflect the lesion’ s volumetric characteristics as the volume had a moderate effect on the choice of PAI score.
