Indiana University-Purdue University Indianapolis (IUPUI) / This investigation examined the relationships of preparation and resin material types in the reattachment of fractured anterior tooth fragments. A total of 44 extracted maxillary central incisors were tested. Statistical analysis revealed that no-handpiece preparation was as retentive as a 45° circumferential bevel (p <.01). In addition, the light-cured resin proved as retentive as did the chemically-cured resin (p<.01). Also examined was the effect of the initial fracture angle on retention of the fragment after reluting. Teeth fractured with an angle sloping cervically in a lingual-to-facial direction when viewed proximally were more retentive than other types of fractures when subjected to a lingually directed force from the labial (p L.OS).

É necessário um conhecimento sedimentado, permanentemente atualizado que, aliado a vivência clínica, pode resultar em planos adequados que possibilitem um melhor prognóstico. A proposta deste trabalho é avaliar os planos de tratamento propostos e os tratamentos efetivamente realizados, nos casos de fraturas coronárias e corono-radiculares, no período de 1992 a 2006. Segundo a classificação de Andreasen, os dados foram obtidos a partir de fichas clínicas da Disciplina de Clínica Integrada e registrados em fichas elaboradas para o estudo. Dos 1552 prontuários registrados no Serviço de Triagem da Faculdade de Odontologia de Araçatuba - UNESP, 549 estão relacionados com algum tipo de fratura coronária e corono-radicular e 1014 dentes foram envolvidos. Os achados foram divididos entre o plano proposto e os procedimentos efetivamente realizados. Nas fraturas envolvendo esmalte, dentina e polpa foram propostos 127 tratamentos endodônticos, enquanto que 54 foram efetivamente realizados. Quanto ao envolvimento das fraturas de esmalte, dentina, cemento e polpa, as alterações estão relacionadas aos 68 procedimentos protéticos propostos x 25 efetivamente realizados, 39 exodontias x 60 realizados, 145 tratamentos de canal x 110 realizados. Houve mudanças entre os planos propostos e o tratamento realizado, sendo que as fraturas corono-radiculares, com ou sem exposição pulpar, mostraram maiores variações, talvez pela complexidade do seu diagnóstico que, em muitas vezes, só é definido após a remoção do fragmento fraturado. / Abstract: Elaborating a treatment plan could be a difficult task, especially if dealing with crown or crown-root fractures. It is necessary a consistent knowledge, permanently updated, that, connected to the clinic experience, could result in adequate plans that make a better prognostics. The purpose of this project is to evaluate the plans of a proposed treatment and the treatment actually performed in the cases of crown and crown-root fractures during the period between 1992 to 2006. The fractures were divided according to the type of dental traumatism (Andreasen, 1974). Data was obtained based on the clinic files of the Integrated Clinic Discipline. Out of 1552 files registered at the Triage Department from Dentistry School in Araçatuba-SP State - UNESP, 549 were related to some type of crown and crown-root fractures and 1014 teeth were involved. The findings were divided between the proposed plan and the procedures actually performed. For the fractures involving enamel, dentin and pulp 127 endodontics treatments were proposed, while 54 were actually performed. As for the involvement of enamel, dentin, cement and pulp fractures, alterations are related to the 68 prothetic procedures proposed x 25 actually performed, 39 procedures of exodontics x 60 performed, 145 canal treatments procedures x 110 performed. There was a change between the proposed plans and the performed treatment. The fractures involving cement with or without pulp exposure, showed more variations. / Doutor
