Generalized aggressive periodontitis.

摘要

The interesting case report of Olgun-Erdemir and her colleagues entitled "Generalized aggressive periodontitis in a child with 92,XXYY/46,XY mosaicism: report of a second case" was well received (Turk J Pediatr 2010; 52: 94-96).Although this kind of mosaicism might be etiologically related to the pathology, I regret to say that the pathogenesis of it, which is more important, was not mentioned.Since the immunological studies did not reveal any pathology, acatalasia should not be ignored in the pathophysiology of aggressive periodontitis1. This pathology could easily be tested by determining catalase level or simply by applying hydrogen peroxide to the oral mucosa or to the blood.
