Tratamiento endodóncico en diente permanente avulsionado y con ápice inmaduro / Endodontic treatment in avulsed permanent teeth with immature apex

La avulsión es un desafío para la integridad dental y puede llevar a necrosis pulpar. En vista de estas características, es imperativo una apexificación para obtener una implantación periodontal más larga y un sellado apical adecuado. El siguiente caso clínico describe una reimplantación de un incisivo central avulsionado y el tratamiento de apexificación a través de curativos a base de hidróxido de calcio. Se concluye que la reimplantación asociada con la obturación radicular con mineral trióxido agregado (MTA) en el incisivo central llevó a una exitosa finalización terapéutica

Dental trauma such as avulsion is a challenge to dental integrity and can result in pulp necrosis. When these characteristics are observed, apexification becomes imperative to obtain an adequate apical seal. The objective of this case report is to demonstrate a replantation of an avulsed central incisor and apexification treatment through calcium-hydroxide-based dressing. It is concluded that the replantation associated with a mineral trioxide aggregate (MTA) root obturation in the central incisor led to a successful endodontic procedure

Apexificación del incisivo central con rizogénesis incompleta y pulpa necrótica asociada con lesión periapical / Apexification of the central incisor with incomplete root formation and pulp necrosis associated with apical periodontitis

Dientes inmaduros con pulpa necrótica presentando foramen apical amplio y paredes delgadas y frágiles, se convierten en un desafío para el tratamiento endodóntico. En vista de estas características, es imperativo una apexificación para obtener un sellado apical adecuado. El siguiente caso clínico describe el tratamiento de apexificación a través de curativos a base de hidróxido de calcio, donde se ha logrado éxito en la formación de una barrera apical osteocementaria. Hemos encontrado que la apexificación a través del uso de la terapia recomendada en el incisivo central con formación radicular incompleta y necrosis, llevó una exitosa finalización endodóntica (AU)

Immature teeth with necrotic pulp and apical foramen presenting large thin and fragile walls, become a challenge to treat conventional endodontic. Faced with these characteristics, it becomes apexification to obtain an adequate apical seal. The objective of this study is to demonstrate a clinical case in which the apexification through calcium hydroxide-based dressing, succeeded in forming an apical osteocement barrier. It is concluded that the apexification through the use of therapy advocated in the central incisor with incomplete root formation and necrotic pulp led a successful endodontic procedure (AU)

Sensitometric evaluation of a periapical radiographic film Dentix E?: effect of different processing conditions / Avaliação sensitométrica do filme radiográfico periapical Dentix E: efeito de diferentes condições de processamento

Objective: Knowing the properties of new radiogra-phic films is essentially important, because from this evaluation depends the learning of such films, directly affecting the radiation dose received by the patient in radiographic examination. Thus, the aim of this study was to evaluate the sensitometric properties of a new film ? Dentix E?, and compare it to E-speed? and Insight? films, processed with different liquids and under different conditions. Methods: The films were exposed at predetermined times and manually processed, using the temperature/time method and ready-to-use liquids from Kodak and Prograd, and were automatically processed with Kodak liquids. Later, the density of those X-rays was measured and the characteristic curves were built in order to determine their sensitometric properties, such as contrast, indicative value of sensibility, and latitude. The values of properties were evaluated by the inclination of curves in the graphs and by descriptive statistics. Results: It was possible to observe that Dentix E? film presented similar characteristic curves and sensitometric properties to E-speed? film, regardless of processing. Conclusion: This result indicates that Dentix E? presents contrast, sensibility, and latitude compatible to films classified as E sensibility.
