In this study the authors evaluated radiographic variations of alveolar bone treated with periodontal therapy, through computerized analysis. Five adult patients with severe periodontitis were included in this study. In everyone of these patients, three sites were selected and treated in the following ways: 1) root planing (LCC), 2) open flap debridement (LCA) and 3) guided tissue regeneration with polytetrafluoroethylene membrane (GTR-PTFE). Every site was subjected to radiographic examination before treatment and six, eight, twelve and twenty-four weeks later. Radiographic images were evaluated through digital processing in order to show and compare one to another changes of alveolar bone of sites treated with different therapeutic procedures. Analysis of data indicated that sites treated by GTR-PTFE developed better than sites treated with other therapeutic procedures and evolution of sites treated with surgery was usually characterized by a beginning phase of alveolar bone loss and by a phase of variable bone regeneration later. Early variations of alveolar bone have been pointed out by mean of this computerized analysis.

This paper presents an unusual case of gingival ALCL, which mimicked a benign hyperplastic lesion that occurred in a 57-year-old white man representing the first clinical manifestation of acquired immunodeficiency syndrome (AIDS). The patient was referred to the Dental Clinic of PUCPR complaining of a lobulated nodule on the gingiva of his upper central incisors. The presence of advanced chronic periodontitis and dental plaque raised suspicion for a benignancy. An excisional biopsy was performed, and large pleomorphic cells with an abundant cytoplasm, sometimes containing prominent nucleoli and "Hallmark" cells, were observed through hematoxylin and eosin staining. The tumor cells showed strong CD30 expression, EMA, Ki-67, and LCA, and negative stain for p80(NPM/ALK), CKAE1/AE3, CD20, CD3, CD56, and CD15. The final diagnosis was ALCL (ALK-negative). Further laboratory tests revealed positivity for human immunodeficiency virus (HIV). The patient was submitted to chemotherapy, but four months after diagnosis, the patient died due to pneumonia and respiratory failure. Oral anaplastic large-cell lymphoma (ALCL) is a rare disorder. Only 5 cases involving the gingiva have been reported, and to our knowledge, this is the first case reported of the ALCL, which mimicked a hyperplastic benignancy as the first clinical manifestation of AIDS.
