The purpose of this cross-sectional study was to evaluate the occurrence of bilateral symmetry in the distribution of clinical parameters in subjects with generalized aggressive periodontitis (GAP) and severe chronic periodontitis (SCP). The sample comprised 53 subjects with GAP and 33 with SCP. Probing depth (PD) and clinical attachment loss (CAL) were recorded from both buccal and lingual interproximal sites of incisors and molars. The symmetry of periodontal destruction was analyzed in terms of intraclass coefficient correlations (ICC) for pairs of contralateral sites at which PD and/or CAL was ≥5 mm at one of the sites of the subjects in each group. GAP patients had a higher proportion of both PD and CAL ≥ 5 mm and also a higher mean proportion of subjects having PD and/or CAL ≥ 5 mm at one or both sites. The GAP group had 20 pairs of contralateral sites with PD (ICC = 0.22-0.63) and 26 pairs with CAL (ICC = 0.20-0.63), the correlation being statistically significant, while the SCP group had only 2 pairs (ICC = 0.36-0.48) with PD and 5 pairs with CAL (ICC = 0.33-0.58) showing a significant correlation. It can be concluded that GAP shows more symmetric periodontal destruction than SCP.
