The inflammatory resorption of dental root apex (i.e., the process removal cementum and/or dentine through activity resorbing cells) may show different configurations and damage apical structure. As knowing morphology areas human teeth is essential for success endodontic treatments, we investigated by scanning electron microscopy, focusing on roots with granulomas. A total 30 (with penetrating carious lesions chronic periapical lesions) were examined, third removed analyzed to estimate periforaminal foraminal resorption, shape foramen centering area, diameters each foramen. Periforaminal was present in all samples, whereas 92% cases (mainly funnel shaped). Lacunae observed area an average diameter 35±14 μm. major minor foramina 443 313 μm, respectively (higher than healthy teeth). This result indicates expansion caused pathology, which could encourage a clinical instrumentation these teeth.
