Avaliação imediata e após 6 meses da resistência de união a dentina de restaurações de resina composta classe I in vivo e in vitro /

Rêgo, Heleine Maria Chagas. January 2015 (has links)
Orientador: César Rogério Pucci / Co-orientador: Eduardo Bresciani / Banca: Taciana Marco Ferraz Caneppele / Banca: Daphne Barcelos / Banca: Dulce Maria Santos Simões / Banca: André Figueiredo Reis / Resumo: Este estudo avaliou a resistência de união a dentina de restaurações de resina composta de forma imediata (24 horas) e em longo prazo (6 meses), submetidos a diferentes protocolos de envelhecimento. Cem dentes posteriores humanos foram divididos em cinco grupos (n = 20) de acordo protocolo de envelhecimento que receberam e posteriormente subdivididos em dois subgrupos (n = 10) de acordo com o tempo de armazenamento, totalizando dez subgrupos: In vivo (permaneceu em atividade bucal por 24 horas ou 6 meses); Estufa (armazenado em água destilada em estufa a 37 °C por 24 horas ou 6 meses); Ciclagem (submetidos a 27/666 ou 5000/120000 ciclos termomecânicos); Estufa com Pressão Pulpar Simulada (PPS) (restauração realizada sob PPS e em seguida armazenado em água destilada em estufa a 37 °C por 24 horas ou 6 meses); Ciclagem com PPS (restauração realizada sob PPS e em seguida submetidos a 27/666 -24 horas- ou 5000/120000 -6 meses- ciclos termomecânicos). Após a abertura da cavidade, a restauração foi realizada com a aplicação de ácido fosfórico a 37% (Vigodent), sistema adesivo Adper Single Bond 2 (3M ESPE) e resina composta Grandio (Voco), seguindo a orientação dos fabricantes. Após os diferentes tratamentos os espécimes foram seccionados obtendo-se palitos que foram submetidos ao teste de microtração. Os valores obtidos foram submetidos ao teste ANOVA dois fatores (protocolo de envelhecimento e tempo de armazenamento) e em seguida ao Teste de Tukey (5%). Os resultados para os testes de microtração foram (em MPa ±dp): Grupo estufa 24 h, 24,96±0,95A; Grupo ciclagem 24 horas, 23,96 ± 0,56AB; Grupo in vivo 24 horas, 23,21 ± 1,23AB; Grupo ciclagem com PPS 24 horas, 19,49 ± 1,51BC, Grupo ciclagem 6 meses, 18,16 ± 0,80CD; Grupo ciclagem com PPS 6 meses, 17,88 ± 1,25CD; Grupo estufa com PPS 24 horas, 17,65 ± 0,45CD; Grupo estufa 6 meses, 16,68 ± 1,30CD; Grupo estufa com PPS 6 meses, 14,33 ± 1,48D; Grupo in vivo 6 meses,.... / Abstract: This study evaluated the bond strength of composite resin restorations submitted to different storage aging protocols, immediately and long-term (6 months). One hundred human posterior teeth were divided into five groups (n = 20) according storage aging protocol: Group, Group in vivo, Group water, Group cycling, Group water with Simulated Pulpal Pressure (PPS) and Group cycling with Simulated Pulpal Pressure. As further subdivided into two subgroups (n = 10) according to the time of storage were performed: 24 hours (24 hours in vivo 24 hours in water, 27/666 thermal and mechanical cycles) 6 months (6 months in vivo, 6 months in water and 5000/120000 thermal and mechanical cycles). After the opening of the cavity, the restoration was carried out with the use of phosphoric acid 37% (Vigodent), Single Bond 2 adhesive system (3M ESPE) and composite resin Grandio (Voco), following the lead of the manufacturers. After being held aging protocols for the storage time subgroup belonging specimens were sectioned obtaining sticks were submitted to microtensile test. Data were submitted to ANOVA two factors (aging and storage time) and then Tukey test (5%). The results for the microtensile tests were (MPa) ± SD: Group water 24 hours, 24.96 ± 0.95A; Group cycling 24 hours, 23.96 ± 0.56AB; Group in vivo 24h, 23.21 ± 1.23AB; Group cycling with PPS 24 hours, 19.49 ± 1.51BC, group cycling six months, 18.16 ± 0.80CD; Group cycling with PPS 6 months, 17.88 ± 1.25CD; Group water with PPS 24 hours, 17.65 ± 0.45CD; Group water 6 months, 16.68 ± 1.30CD; Group water with PPS 6 months, 14.33 ± 1,48D; In vivo group 6 months, 14.16 ± 1,51D. It was concluded that the different aging protocols used as storage times influence the bond strength dentin-resin / Doutor
