With most cases occurring in children younger than 10 years, it is remarkably rare in adults. Further in adults, the typical pediatric rhabdomyosarcoma variants (embryonal and alveolar sub-types) occur less frequently(More)
Myxomas of the head and neck are rare tumors of uncertain histogenesis. Odontogenic myxomas in maxilla are less common but behave more aggressively, as it spreads through maxillary antrum. It therefore reaches considerable size before being detected. The current case arouses particular interest due to the rapid growth and infiltrating nature of the lesion(More)

The spontaneous eruption may be associated with pain, inflammation of adjacent soft tissues or recurrent infection. The present case of complex odontoma is of particular interest due to its apparent eruption in(More)
BACKGROUND Dental plaque being one of the most-studied biofilm communities, is particularly complex because it consists of thousands of bacterial species, and new species are still being isolated and characterized. The aim of the present study is to characterize surface topography of the biofilm formed by a new bacterial isolate, obtained from the dental(More)
