ABSTRACT
Abstract The aim of this study was to evaluate in vitro the influence of 20% glycolic ginger extract on the bond strength of glass-fiber post cemented with etch-and-rinse or self-etching resin cement. Forty-eight bovine roots were standardized (17±0.5 mm) and randomly divided into two groups, according to irrigant used during biomechanical preparation NaOCl 1% sodium hypochlorite and GEN 20% glycolic ginger extract. Root canal was prepared and randomly assigned to one of two subgroups (n=12), according to luting protocol self-etching (RelyX U200) and etch-and-rinse (RelyX ARC). After 48 h, the roots were sectioned perpendicularly (4 in cervical third and 3 in middle third) and submitted to push-out bond strength test (50 kgf load cell, 1.0 mm/min). Failure mode was analyzed in SEM and stereomicroscopy. Data were analyzed by three-way ANOVA and Tukey tests (p<0.05). ANOVA revealed that there were no significant differences between U200 (2.01±0.17)B and ARC (1.93±0.12)B in GEN group, and at the cervical third for both irrigants, 2.69±0.16A and 2.54±0.17A, respectively. Middle third showed lower bond strength than cervical third, regardless the irrigant. Overall, the cervical third regardless the irrigant employed and the association between NaOCl and ARC, presented better adhesive performance.
RESUMO
Resumo O objetivo deste estudo foi avaliar in vitro a influência do extrato de gengibre 20% na resistência adesiva de pinos de fibra de vidro cimentados com cimentos resinosos convencional ou autocondicionantes. Quarenta e oito raízes bovinas foram padronizadas (17±0.5mm) e aleatoriamente divididas em dois grupos (n=24), de acordo com o irrigante utilizado durante o preparo biomecânico NaOCl hipoclorito de sódio 1%; e GEN extrato glicólico de gengibre 20%. Os canais radiculares foram preparados e aleatoriamente distribuídos em dois subgrupos (n=12), conforme o protocolo de cimentação autocondicionante (RelyX U200) e convencional (RelyX ARC). Após 48 h, as raízes foram seccionadas perpendicularmente (4 no terço cervical e 3 no terço médio) e submetidas ao teste de resistência adesiva push-out (50 kgf carga, 1.0 mm/min). O modo de falha foi analisado em MEV e estereomicroscopia. Os dados foram analisados pelos testes ANOVA 3-fatores e Tukey (p<0.05). ANOVA mostrou que não houve diferenças significativas entre U200 (2.01±0.17)B e ARC (1.93±0.12)B no grupo GEN, e no terço cervical para ambos os irrigantes (2.69±0.16A and 2.54±0.17A, respectivamente). O terço médio apresentou menor resistência adesiva que o terço cervical, independente do irrigante. Em geral, o terço cervical, independentemente do irrigante empregado, e a associação entre NaOCl e ARC apresentaram melhores desempenhos adesivos.
