The aim of the study was to evaluate the sealing ability of five root-end filling materials. Methods: Fifty human single rooted teeth were treated endodontically; roots were resected at 3 mm from the apex, and root end cavities were prepared with ultrasonic tips. Root ends were filled with one of the following materials: silver amalgam (control group); mineral trioxide aggregate; white Portland cement; Vitremer; and Fuji Ortho. Apical sealing was evaluated by evaluating microleakage of 50% silver nitrate solution. The apical portion of the roots was sectioned to obtain 1-mm thick transversal slices, and epoxy resin replicas of these apical slices were produced. A scanning electron microscope (SEM) was used for analyses. The Kruskal-Wallis test and a multiple comparisons test were used for statistical data analysis. Results: Results showed microleakage and variable adaptation gaps on the interface between dentin and root-end filling material in all specimens. Conclusion: All the studied materials exhibited some degree of apical microleakage and marginal gaps. No correlation was found between data obtained from analyses of apical sealing and marginal adaptation.

The International Association of Dental Traumatology divides this trauma into several categories and guides the conduct according to each category. The aim of the present study is to report a case of dental reimplantation of the upper central incisor in a patient with incomplete rhizogenesis. An 8-year-old male patient sought care after undergoing avulsion of upper left central incisor and left superior deciduous lateral incisor teeth and subluxation of the upper right central incisor tooth. The upper left central incisor tooth was maintained in dry medium and reimplanted in < 60 min after avulsion. The flexible restraint from the upper right canine deciduous to upper left canine deciduous remained for approximately 21 days. The clinical-radiographic follow-up was periodic and after 34 months posttrauma was observed crown integrity, root growth continuity, calcification of the canal of upper left central incisor, absence of radiographic image compatible with periapical lesion, and negative response to the pulp vitality test in the upper left central incisor tooth. We conclude from the exposed clinical case that, even with predictable sequelae, such as calcification of the root canal space and dental reimplantation is the procedure of choice in cases of dental avulsion.

Objetivo: Obter um perfil de pacientes com TEA atendidos em um centro de especialidades odontológicas (CEO) do sul do Brasil, verificar a necessidade de atendimento odontológico sob anestesia geral (AG) e analisar fatores sociodemográficos, comportamentais, médicos e odontológicos associados. Material e métodos: Este estudo observacional transversal utilizou dados secundários de prontuários de pacientes com TEA atendidos no CEO Jequitibá da Faculdade de Odontologia da Universidade Federal de Pelotas, localizado na cidade de Pelotas/RS.

O presente caso clínico visa a relatar a técnica de obturação do canal radicular simultânea ao ato cirúrgico, bem como enfatizar os passos operatórios a serem seguidos para obtenção do sucesso operatório.

MATERIAL AND METHODS: Eighty human maxillary canines were selected and treated endodontically. The apical ends were sectioned and root-end cavities were prepared. The sample was randomly divided in four groups of 20 specimens each. In each group, root-end cavities were filled with one of the following materials: ethyl cyanoacrylate (EC); silver zinc freea amalgam (AM); resin-modified glass-ionomer cement (GIC); or resin-modified glass-ionomer cement and light curing (GIC+light). Specimens were immersed in 0.2% methylene blue for 24 hours at 37° C and then sectioned longitudinally. The analysis of dye penetration was conducted by means of visual inspection of the buccal and lingual sections of the roots. RESULTS: Analysis of variance was used to compare results. The least marginal leakage was found in the EC group, followed by the GIC+light, GIC a...

Em resposta ao traumatismo, a mandibula, devido a sua morfologia ser semelhante a uma ferradura, distribui a forca de impacto por todo seu comprimento. Todavia, ela nao possui uma curva suave de osso uniforme, mas sim descontinuidades como, por exemplo: forames, curvaturas agudas, bordas alveolares e regioes com seccao transversal diminuida. Como resultado, partes da mandibula desenvolvem maior forca por unidade de area e, consequentemente, a deformacao de tracao e concentrada nesses locais.
