    Accurate diagnosis, immediate care and proper treatment planning are important factors for the successful treatment of dental traumatic injuries. In extrusive luxation, postponement in treatment may lead to the need for new strategies for the resolution of unwanted consequences. The present case report describes an unusual condition of delayed treatment regarding extrusive luxation of two anterior teeth treated by intentional replantation. An 18-year-old female patient attended the Dental School for the treatment of a traumatic injury to the anterior teeth 5 days after a fall from a bicycle. Clinically, teeth #21 and #22 were extruded in incisal edges for 5 mm from their neighboring teeth, had edematous gingiva, showed grade II mobility and were painful to percussion. Radiographically, the roots were intact and the periodontal ligament space was thickened along its entire length. As immediate repositioning could not be performed, intentional replantation was recommended. After detaching the periodontal ligament, the teeth were extracted and the alveolus was curetted and irrigated with saline solution to remove the already-formed clot. After replantation, the teeth were restrained and the patient was medicated with antibiotics as well as analgesics. After 10 days, the splint was removed, the root canals were instrumented and then, filled with calcium hydroxide. After 30 days, they were completely obturated using gutta-percha. The 5-year follow-up showed root integrity, absence of mobility and normal periodontium. The outcomes of the current case report revealed that when intentional replantation was properly conducted, it could be considered an option for the treatment of extrusive luxation where the teeth were not to be immediately repositioned

    Abstract The aim of this study is to evaluate the action of paramonochlorophenol associated with Furacin followed by calcium hydroxide (CH) dressing in the control of inflammatory root resorption in cases of immediate tooth replantation with delayed endodontic treatment. A total of 28 incisors of 3 male dogs were extracted and replanted after 15 minutes, and randomly divided into 3 groups: Group I (n = 8) - endodontic treatment was performed before the extraction and replantation; Group II (n = 10) - endodontic treatment was performed 30 days after replantation and the root canal was filled with CH dressing; Group III (n = 10) - endodontic treatment was performed 30 days after replantation and root canals received temporary medication of paramonochlorophenol-Furacin followed by CH dressing. The animals were euthanized 90 days after replantation. The histomorphological events analyzed at the epithelial reattachment site were the intensity and extent of acute and chronic inflammatory processes, periodontal ligament (PDL) organization, the intensity and extent of acute and chronic inflammatory processes in the PDL space, root resorption, bone tissue, and ankylosis. Data were submitted to the Wilcoxon Signed Ranks Test for group comparison (α = 5%). In Groups I, II and III the periodontal ligament was regenerated and most of the resorption areas were repaired by newly formed cementum. The depth and extent of root resorption were significantly higher in Group II than in Group III. The use of paramonochlorophenol-furacin followed by CH dressing was more effective in controlling inflammatory root resorption after immediate tooth replantation

    http://dx.doi.org/10.5902/010283085718A tradição (ou a Educação Física tradicional) vem demonstrando mais resistência à mudança do que o esperado pelo movimento renovador da década de 1980. Aos poucos as esperanças iniciais de mudanças massivas da prática, deram lugar a uma expectativa mais modesta de fomentar inovações ou mudanças locais. Uma mudança no enfrentamento teórico-metodológico do problema está relacionada ao reconhecimento da importância do professor e de sua formação nesse processo, bem como, da consideração do ambiente concreto da escola, ou seja, o “chão da escola” ou o cotidiano escolar. Assim sendo, o presente artigo constitui-se numa tentativa de identificar e compreender os processos de inovação pedagógica na Educação Física, levados a efeito por professores em contextos específicos. Tem a intenção também, de dar visibilidade a estas experiências na expectativa de potencializar outras.Palavras chave: Educação Física. Inovação. Prática pedagógica

    Systematic review of the effects of excessive occlusal mechanical load on the periodontum of rats

    Objective: This study aims to systematically evaluate the effects of traumatic occlusion on the periodontal tissue of rats. The set of questions to be answered were–Can traumatic occlusion acting on a healthy and an unhealthy periodontium cause periodontal destruction? Design: The protocols for systematic review were all developed, following the Preferred Reporting Items for Systematic reviews and Meta-Analyses statement and applied to animal research. Reporting of In vivo experiment guidelines for reporting animal research to assess the risk of bias of the studies. Materials and Methods: A literature search was conducted using MEDLINE through PubMed and manual search from the reference lists of main articles related to the theme. Results: This search strategy identified 65 references, of which 33 were considered inappropriate. The full texts of 32 articles were read, 31 of which did not meet the eligibility criteria and were excluded. The final selection included 1 article for which data was extracted for further evaluation. The article included shows a strongest reaction in the periodontium in front of a secondary occlusal trauma as inflammation and apical migration of the junctional epithelium, bone degradation, and decrease in the quantity of collagen fiber. However, primary occlusal trauma also presents these alterations, with the exception of apical migration of the junctional epithelium. Conclusions: Although only one study was included in the systematic review of traumatic occlusion, there is some evidence from experimental studies on animals that shows a coherent picture of the effects of traumatic occlusion on the periodontium. However, new studies are needed to fully answer the questions posed by this systematic review
