Background and Objective The aim of this study was to describe the radiographic features of the first molars of patients with localized aggressive periodontitis ( LA gP) and of their associated intrabony defects and to compare them with a control sample of chronic periodontitis cases and healthy subjects. Methods Data from a total of 93 patients were included in this analysis. First, dental panoramic tomograms of 34 patients with LA gP (131 first molars) and 30 periodontally healthy patients (110 first molars) were compared. Then, periapical radiographs of the first molars of the same patients with LA gP and of 29 patients with chronic periodontitis affected by intrabony defects were analysed. Results Shorter root trunks were associated with the presence of intrabony defects in patients with LA gP ( P = .002 at multilevel logistic regression), also when LA gP molars were compared with healthy subjects ( P = .036). Although no difference in defect depth and angle was noted between LA gP and chronic periodontitis intrabony defects, LA gP intrabony defects appeared to be more frequently symmetrical and arch‐shaped than in chronic periodontitis ( P = .008), with positive predictive value and negative predictive value of for ‘wide arch’ defect of 87.3% (95% CI = 77.2%‐93.3%) and 32.3% (95% CI = 27.7%‐37.2%) respectively. Conclusion First molars of patients with LA gP 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 LA gP and chronic periodontitis cases. Further studies need to confirm these features and investigate if they are related to the initiation and progression of periodontitis.
