Abstract

GROBLER, SR; PATEL, N; FORTUIN, A  and  MOODLEY, DS. Insights into a comparison of three different cements on the push-out bond strength of a glass-fibre post. S. Afr. dent. j. [online]. 2017, vol.72, n.3, pp.126-127. ISSN 0375-1562.

One of the main causes of failure of fibre posts is de-bonding of the post in the prepared post space. The adhesive properties of total etch adhesive cements were assessed by comparing the performance of cements using self-etching adhesive resins, to verify which system provided the best retentive capabilities with a double tapered post system. Extracted maxillary central incisors were endodontically treated and randomly divided into three groups: the Calibra (Dentsply), RelyX Ultimate (3M ESPE) and Panavia F2.0 (Kuraray) groups. RelyX Ultimate produced significantly the highest de-bond stress values (p<0.05) in the overall performance, as well as in the coronal, middle and apical sections of the tooth. Thus RelyX Ultimate with self-etching adhesive reliably can be used for post cementation with a double tapered post system in endodontically treated anterior teeth.
