AB  - Purpose: To determine the fracture resistance of different sizes of standardized single fiber posts and the combinations of multiple small experimental posts. Methods: Single posts in three different sizes (l, 2 and 3; DT Light Posts, RTD; DT), as control, and seven different combinations of experimental small posts (Abrasive Technology), reproducing the sizes of several endodontic files were cemented in endodontic resin blocks. The combinations of small posts were made combining 2-4 small posts so as to reach the sizes of standardized DT posts. The posts were loaded at an angle of 45 to the long axis of the block using a crosshead speed of 1 mm/minute until specimen failure. Ten posts/combinations were tested. Statistical analysis was performed using one-way ANOVA followed by Tamhane test for the post hoc comparisons (P lt  0.05). Results: For the single posts, fracture resistance increased when increasing the diameter of the post. The use of multiple posts resulted in fracture resistances comparable to that of the single post for two of the three diameters studied (DT1 and DT2). For the largest diameter (DT3), the use of multiple posts resulted in lower fracture resistances than did the single post. (Am J Dent 2008;21:373-376).

AB  - Purpose: The aim of this study was to evaluate the influence of the operator's experience on the outcome of fiber post cementation using an etch-and-rinse acetone-based adhesive. Materials and Methods: Fifteen human anterior teeth were used in the study. One trained operator performed the endodontic procedures and prepared the roots for the insertion and cementation of the posts. At this point, teeth were divided into 3 groups and distributed to 3 operators to lute the posts: an expert operator (EO), a moderately experienced operator (ME), and an operator with a low level of experience (LE). Quartz fiber posts (DT Light Post #1 or #2, RTD) were used. Posts were cemented using Prime&Bond NT Dual Cure adhesive system (Dentsply Caulk) in combination with the dual-curing resin cement Calibra (Dentsply Caulk). The post retention was assessed with the "thin-slice" push-out test. One-way ANOVA was performed to examine the effect of the operator on push-out strength, followed by post-hoc multiple comparisons using Tukey's test, with the significance level set at alpha = 95%. Results: The results of push-out strength testing were as follows: EO (12.44 +/- 3.63 MPa), ME (11.68 +/- 2.64 MPa), LE (11.18 +/- 3.12 MPa). No statistically significant differences were determined among the three groups. Conclusion: There was no statistically significant difference in the retention measured for fiber posts luted by operators with different levels of clinical experience. Given the parameters of this investigation, the level of operator experience in luting fiber posts does not affect post retention under laboratory conditions.
