Purpose:
This study investigated the influence of the fiber sleeve on push-out bond strength (PBS), both with and without aging in a mastication simulator.
Materials And Methods:
Sixty straight-rooted mandibular premolars were randomly divided into four groups (n = 15). Groups S and SMS included fiber sleeves and posts, while Groups P and PMS included posts only. Groups SMS and PMS underwent aging in a mastication simulator (50 N load, 240,000 cycles). Specimens were sectioned into 1 mm slices (coronal, middle, apical thirds), and PBS testing was performed using a universal testing machine. Failure modes were analyzed under 40× magnification. Statistical analysis used one-way ANOVA and Tukey tests (α = 0.05).
Results:
Group S had the highest PBS, significantly surpassing Group P (P < 0.001). Aging significantly reduced PBS in sleeve groups (S vs. SMS, P = 0.029) Adhesive failure between dentin and cement was most common.
Conclusion:
The use of fiber sleeves significantly improved PBS; however, this enhancement diminished following aging procedures.

Posttensioned Masonry Walls
Post-tensioned masonry walls use high-strength steel rods or flexible tendons to enhance the strength and efficiency of masonry structures. These elements are securely anchored to the foundation and extend vertically either within the cores of the masonry units or between the masonry wythes. The construction process involves building the wall with these tensioning elements in place and allowing the mortar to fully cure.
Following the curing process, the tensioning begins. Steel rods are...
