Compare push -out in the cementing fiber post with resin BulkFill and posts previously adapted in ducts of different diameters
Objectives: Objetive: To Compare the value of adhesive strength measured in megapascals (Mpa) in the cementing fiber post (PF) in ducts of different diameters cemented resin BulkFill SureFil (BK) and posts previously adapted with conventional resin bonded with cement RelyX Ultimated (RU).
Methods: Methods: 20 human teeth were endodontically treated and remove the crown. The endodontic filling was partially removed and divided in four groups according to the cementation material and diameter of the root canal. The groups BD4, BD6, AD4, AD6 were formed. The used fiber postes were N°2 and they were cemented using universal adhesive No., the BD4 and BD6 groups with BK resin and AD4 and AD6 groups were cemented with RU. The teeth went under 500 thermocycling cycles, then were sectioned transversely with a Isomet 1000 cutter into 3 sections of 2 mm height in the apical, medium and apical third, finally they were subjected to push-out test with a speed of 0.5mm / min. force eviction Mpa extent was assessed and observed the failure with 4x optical microscopy. Statistical analysis based on ANOVA two way and post-hoc Tukey with a significance level of 95%. Results: The mean and standard deviation (DS) for BD4 was 27.74(±6.93), to BD6 of 23.21(±8.11) to AD4 of 23.53(±5.87) and AD6 19.21 (±5.99)
Results: Results: The mean and standard deviation (DS) for BD4 was 27.74(±6.93), to BD6 of 23.21(±8.11) to AD4 of 23.53(±5.87) and AD6 19.21 (±5.99)
Conclusions: Conclusion: There is only statistically significant difference between groups BD4 and AD6 with a lower value of adhesive strength for the AD6 group cementing adapted and fiber posts cemented with resin cement (UK).
