Hidróxido de cálcio como medicação intracanal em casos de necrose pulpar com lesão periapical

Prevalence of microorganisms in root canals of human deciduous teeth with necrotic pulp and chronic periapical lesions Prevalência de microrganismos em canais radiculares de dentes decíduos de humanos com necrose pulpar e lesão periapical crônica

The objective of this study was to evaluate bacterial prevalence in 31 root canals of human deciduous teeth with necrotic pulp and periapical lesions using bacterial culture. After crown access, the material was collected using absorbent paper points for microbiological evaluation and determination of colony forming units (CFU). Anaerobic microorganisms were found in 96.7% of the samples, black...

Um Modelo Integrado de Requisitos com Casos de Uso

Elaboração de Especificações de Casos de Uso para Linhas de Produto de Software Baseada em Fragmentos

Use cases are widely used for functional requirements elicitation and specification of information systems. However, writing use case textual specifications for Software Product Lines is a laborious task and the resulting model can become overloaded for practical use. To overcome these issues, a two-phase method is proposed: in the first phase, a set of domain use case fragments is elaborated f...

Nevo de Reed (nevo de células fusiformes): relato de três casos com padrões dermatoscópicos distintos

Reed nevus or pigmented spindle-cell nevus may mimic cutaneous melanoma; however, its dermoscopic and histopathological characteristics are different. This case report describes three patients with distinct clinical, dermoscopic and histopathological presentations, which were correlated to enable a differential diagnosis to be made between melanoma and Spitz nevus

Disseminacao de mensagens DTN com base em grupos de interesses

Recent works explore social characteristics of nodes to improve message delivery rate in Delay Tolerant Networks (DTN). This work uses machine learning techniques to create node groups organized by common interests. Messages are sent to target groups, and from there to the final destination. Simulation results using The ONE simulator show that the larger the group size the higher the message de...
