The desmoplastic fibroblastoma (DF) is a rare benign soft-tissue tumor of fibroblastic and myofibroblastic origin, and its occurrence in the oral cavity is rare. This study details a new case of an elevated lesion in the alveolar ridge of a 59-year-old woman, painful during mastication. The histopathological exam sh...

Objectives: To evaluate the in vitro cytotoxic effects of hydrogen peroxide (H2O2) on periodontal cells, based on the cellular viability and morphology of immortalized osteoblast and gingival fibroblast cultures, with different exposure times and concentrations. Methods: Immortalized human gingival fibroblast and hu...

In vitro cytotoxicity testing of dental acrylic resins is fundamental to establish clinical safety limits, requiring suitable cell models that closely simulate physiological processes. This study’s main aim is to evaluate the viability of an untransformed human gingival fibroblast cell line, as an oral cell mo...

Aim: To evaluate the effect of acetylcholinesterase on the cytotoxicity of three autopolymer-izing acrylic reline resins through the effect of the materials’ eluates, liquids and respective pure compounds on the cellular viability of primary dermal fibroblasts cultures. Methods: Disk shaped specimens of two direc...
