Spontaneous healing responses detected by cone-beam computed tomography of horizontal root fractures: a report of two cases

Horizontal root fractures (HRF) usually affect the anterior teeth as a result of trauma, and generally heal spontaneously, depending on the vitality of the pulp. Diagnosis based on clinical findings, sensitivity tests, and radiographic examination is important to determine the presence of a root fracture and to prevent a root fracture from passing unnoticed. Cone-beam computed tomography (CBCT) has been used successfully for diagnosis and prognosis imaging of root fractures and has proved to be superior to other radiographic methods. This study reports two cases of dental trauma caused by a collision and a sports accident. The patients suffered horizontal root fractures in the maxillary left central incisor and in the mandibular left central incisor. The diagnosis of root fracture was confirmed by cone-beam computed tomography (CBCT) images, which also demonstrated spontaneous healing of the fracture line. The repair occurred by interposition of connective tissue in the former case and by interposition of bone and connective tissue in the latter case. The final diagnoses of both cases were based on CBCT images, indicating the importance of a CBCT examination to reach a firm diagnosis and to follow the healing process of root fracture cases, avoiding unnecessary radical endodontic treatment.

Superação da dormência de sementes de Tucum (Astrocaryum huaimi Mart.)

The objective of this study was to evaluate the effect of immersion for varying periods in different concentrations of gibberellic acid and separate methods of scarification on the germination of seeds tucum. In the first trial, testing different soaking periods (24 and 48 hours), different forms of soaking (fast and slow) and different concentrations of gibberellic acid (0, 100 and 200 mg L-(1)) compared to the control (water) under completely randomized design in a factorial 2x2x3. The second experiment evaluated the different scarification treatments being: physical (seed coat removal in the hilar region with the aid of a scalpel), chemical (sulfuric acid 98 PA for 2:04 minutes) and thermal (hot water at approximately 98 degrees C and cold water at about 2 degrees C for 4 minutes). In the first trial were evaluated % of contaminated seeds (seeds infected by microorganisms) and hard seeds (who did not start the germination process, but not soiled), and in the second we assessed germination percentage (%) every two days for three months; germination Speed Index (GSI), time to occurrence of 50 % germination (T50) and Emergency Speed Index (ESI). The use of gibberellic acid was ineffective in promoting germination of Tucum (Astrocaryum Huaimi Mart.). Scarification treatments were effective in promoting germination and emergence of seedlings in the nursery and the most efficient physical removal scarification of the seed coat in the hilar region with the highest percentage of germination.

Youtube: práticas discursivas e identitárias no ciberespaço

Inegavelmente, as mídias tradicionais como a televisão, o rádio e a mídia impressa detêm grande influência na sociedade contemporânea, tanto para o delineamento do pensamento coletivo, quanto para a sugestão à formação cultural por meio de enunciados produzidos por sujeitos que ocupam determinadas formações sócio- ideológicas. Entretanto, atualmente, um objeto que tem ganhado espaço privilegiado, diferente das mídias tradicionais, são as mídias digitais. Fluidos no grande oceano do ciberespaço que se constitui como um aglutinador de mídias, onde se mesclam mídias tradicionais e novas mídias, centros recepto-difusores encontram-se dispersos em toda parte e, efetivamente, em parte alguma, tornando-se, assim, um espaço onde a cultura participativa e (d)a interatividade ganham traços. Dessa maneira, o presente trabalho, embasado principalmente pelo aporte teórico da Análise do Discurso de linha francesa, tendo como fio condutor as reflexões de Michel Foucault, procura discutir questões de identidades produzidas e veiculadas nos meios digitais. Toma-se como corpus de análise vídeos caseiros de pessoas “anônimas” que transmitem-se pelo canal do YouTube, onde mostram suas habilidades vocais, artísticas e até mesmo conhecimentos de técnicas áudio-visuais para a produção de efeitos de sentido. Estes sujeitos fazem uso de técnicas de confissão para a construção e afirmação de uma identidade de “artista” e, por essas práticas, produzem novas subjetividades. Em torno destes vídeos, ainda, são originadas comunidades inteligentes de pertencimento pontuadas no próprio YouTube e em outras plataformas, como no Twitter, Facebook, My Space, etc. onde são mobilizados e compartilhados os savoir-faire desses sujeitos e virtualizadas e atualizadas as identidades à luz de uma cultura da convergência.

Preservação do patrimônio escolar no Brasil: notas para um debate

This article comprises of a reflection on the challenges of the school heritage conservation in Brazil. First, it analyses the place for school heritage thin in a much more ample field of cultural heritage. Then, it points out problematic questions assumed in the debate on heritage in the education area and examines the consequent sense of the school converted in “place of memory”. The text defends the indispensability of the insertion of the school heritage in the public, political and specialized debate in the field of conservation as a condition for the development of education heritage in the country.
