Impact of post adhesion on stress distribution: an in silico study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objectives: This study aimed to evaluate the stress distribution in teeth restored with different post materials and bonding conditions using finite element analysis (FEA). Methods: A two-dimensional FEA model of a maxillary central incisor restored with IPS-Empress-2 crown (Ivoclar Vivadent), composite resin core, and posts were created. The model simulated bonded and non-bonded conditions for both fiber-reinforced composite (FRC) and titanium (Ti) posts. Stress distribution was analyzed using ANSYS 14.0 software under a 100-N load applied at a 45° angle to the long axis of the tooth. Results: The results revealed that stress concentration was significantly higher in non-bonded posts compared to bonded ones. FRC posts exhibited stress values closer to those of dentin, whereas Ti posts demonstrated higher stress concentration, particularly in non-bonded states, increasing the potential risk of damage to surrounding tissues. Conclusions: FRC posts, with elastic properties similar to dentin and proper adhesion, minimize stress concentration and potential damage to surrounding tissues. Conversely, materials with higher elastic modulus like Ti, can cause unfavorable stress concentrations if not properly bonded, emphasizing the importance of post adhesion in tooth restoration.
