One of the main causes of failure of fibre posts is debonding
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.
