Factitious gingival ulceration: as presenting sign of Munchausen's syndrome?

abstract：:A role for activated B-lymphocytes in mediating the initiation and/or progression of periodontal diseases has been proposed in previous work. The present study was conducted to: (1) assess the proportion of total lymphocyte blastogenic response to selected oral bacteria which is composed of T-cell and B-cell activatio...
