Abstrakt: Tumors of the oral cavity include combinations of hard and soft tissues that may be difficult to identify using routine hematoxylin and eosin (H & E) staining. Although combination stains can demonstrate hard and soft tissues, trichrome stains, such as VanGieson and Masson, cannot differentiate dental hard tissues, such as dentin, cementum and osteoid. Modified Gallegos (MGS) and verdeluz orange G-acid fuchsin (VOF) stains can differentiate components of teeth. We used 10 tissue sections of decalcified bone and 10 pathologic tissue sections that contained different calcified tissues including peripheral ossifying fibroma, odontoma, central ossifying fibroma and cemento-ossifying fibroma. Sections were stained with H & E, VOF or MGS. H and E stained both hard tissues pink. VOF stained bone purple-red, cementum red and collagen blue. MGS stained bone green-blue, cementum red and collagen blue. VOF staining intensity and differentiation was better than MGS staining. VOF staining demonstrated hard tissue components distinctly and exhibited good contrast with the surrounding connective tissue. VOF also is a simple, single step, rapid staining procedure.
