Comparisons of pocket depth (PD), clinical attachment level (CAL), and JP2 presence alone or with non-JP2, in terms of localized aggressive periodontitis (LAP diseased sites only (LAPd; a, c) or all diseased and healthy sites in LAP patients (b, d). No difference was found on PD by analysis of variance among the 3 categories of JP2 (b), but Mann-Whitney test comparing only presence versus absence of JP2 was significant (*P < 0.05). Kruskal-Wallis with Dunn’s multiple comparisons test showed a difference in mean CAL between JP2-positive and JP2-negative sites in all LAP sites (d; *P < 0.05), specifically between sites negative for JP2 and sites with only JP2.
