Cystic Lesions and Odontogenic Tumors in Older People: A Brazilian Multicenter Study.

Background: Some odontogenic cysts (OCs) and odontogenic tumors (OTs) are infiltrative and often recur, causing bone destruction and tooth loss. In the elderly, in particular, these injuries cause significant morbidity, making rehabilitation difficult and compromising the quality of life of these individuals. Objective: To determine the prevalence and demographic characteristics of OCs, non-odontogenic cysts (NOCs), and OTs diagnosed in an elderly Brazilian population (≥60 years).

Diversity, prevalence and phylogenetic positioning of Botrytis species in Brazil.

Botrytis is a necrotrophic fungal genus of great economic importance worldwide. Together, the Botrytis species are able to infect over one thousand host plant species, including dicotyledons and monocotyledons. As the identification of Botrytis species in Brazil has mostly been based only on morphological characterization and comparisons of the rDNA ITS region, which is not informative in the genus, its diversity remains unknown.
