Histomorphometric comparison of three bioabsorbable GTR barrier membranes in the canine model.

Guided tissue regeneration (GTR) using bioabsorbable barrier membranes has shown promising and somewhat predictable clinical results. However, limited information is available on the stages of histologic healing when these types of barriers are used. Therefore, the aim of this study was to compare three currently available bioabsorbable GTR barriers (type 1 collagen, polylactide/polyglycolide copolymer, and citric acid copolymer) for the treatment of surgically created periodontal dehiscences in dogs.

Chronic Sialadenitis revealing hepatitis C: a case report.

One 53-year-old male was referred with a history of sensitive peripheral neuropathy and Raynaud disease leading to suspect a Sjögren syndrome (SS). Labial salivary gland biopsy shown the classical features of chronic lymphocytic sialadenitis. As clinical and immunologic tests were positive, we conclude to a chronic lymphocytic sialadenitis simulating SS.
