Abstract
Aim: To evaluate the effect of different methods of fiber post cleaning on post resistance to dislodgement after cementation. Methodology: Sixty bovine incisors were divided into six groups according to the cleaning method applied to the fiber posts. GC: no cleaning; GES: autoclave sterilization; GHP: 2.5% sodium hypochlorite; GCL: 2% chlorhexidine digluconate; GAL: 70% alcohol; GAF: 35% phosphoric acid. The posts were cemented in the canals using a self-adhesive resin cement. The specimens wer ...
Aim: To evaluate the effect of different methods of fiber post cleaning on post resistance to dislodgement after cementation. Methodology: Sixty bovine incisors were divided into six groups according to the cleaning method applied to the fiber posts. GC: no cleaning; GES: autoclave sterilization; GHP: 2.5% sodium hypochlorite; GCL: 2% chlorhexidine digluconate; GAL: 70% alcohol; GAF: 35% phosphoric acid. The posts were cemented in the canals using a self-adhesive resin cement. The specimens were sectioned perpendicularly along the long axis of the root with an av-erage thickness of 1.61 mm at the cervical, middle, and apical root thirds and subjected to the push-out test. After the test, they were examined under a stereomicroscope to de-termine failure mode. Data were analyzed using one-way ANOVA and the Tukey test (α=0.05). Results: The comparisons with the GC group revealed statistical differences only in the middle and apical thirds of the GCL group and in the apical third of the GHP group. Only the apical thirds were different from the middle and cervical thirds in the GC group, and the cervical thirds, from the middle and apical thirds of the GES group. Conclusions: The resistance to dislodgement of fiber posts cemented in root canals was not affected by the different cleaning methods under study. ...
