Radiographic morphology of intrabony defects in the first molars of patients with localized aggressive periodontitis: Comparison with health and chronic periodontitis.

First molars of patients with LAgP affected by intrabony defects may have some distinct radiographic anatomical characteristics to those of healthy subjects. The shape of intrabony defects seems to differ between LAgP and chronic periodontitis cases. Further studies need to confirm these features and investigate if they are related to the initiation and progression of periodontitis.
