“…The high configuration cavity factor (C-factor) within the canal and the shrinkage of polymers in a thick layer of cement can lead to the formation of gaps. Gaps can form along the interface of cement and post or cement and dentin [66]. Moreover, a thick layer of cement increases the likelihood that bubbles or voids will form during application [66].…”

“…It was proposed to use a relining technique to customize the post with RBC to fit the canal's shape, resulting in minimum cement thickness. This is advantageous for several reasons, including the retention of the post, the improvement of tooth fracture strength, and the reduction of stress transferred to the surface of the cervical root [66].…”

The field of dental medicine is constantly evolving and advancing toward minimally invasive techniques. Several studies have demonstrated that bonding to the tooth structure, particularly enamel, yields the most predictable results. In some instances, however, significant tooth loss, pulpal necrosis, or irreversible pulpitis may limit the options available to the restorative dentist. In these cases, placement of a post and core followed by a crown is the preferred treatment option, provided all requirements are met. This literature review provides an overview of the historical development of dental FRC post systems as well as a comprehensive examination of the currently available posts and their bonding requirements. In addition, it offers valuable insights for dental professionals seeking to understand the current state of the field and the prospects of dental FRC post systems.

Previous clinical studies have indicated that the loss of retention between post and tooth is a major cause of failure in the restoration of endodontically treated teeth. Since bubble-like defects were found in the cement layer of the debonded post, we hypothesized that this cement defect decreases the adhesive strength. The purpose of this study was to evaluate if the technique used to insert resin cement influences the presence of bubbles and the push-out bond strength. Methods: The root canal of a transparent resin block and bovine tooth were parallel-wall drilled with a Peeso Reamer to achieve a post length of 10 mm. Prefabricated metal posts were cemented using self-adhesive resin cement, for nine combinations of three tools and three cement application sites. The resin block was scanned with a digital camera, then image analysis software was used to calculate the percentage of bubbles in the cement layer. Bovine teeth were sectioned into five 1-mm thick slices for the push-out bond strength test. Results: The bubbles were concentrated at the apical side for all methods. When we used the plastic needle to apply cement to the post and root canal, the bubble mixture rate was significantly lower than that of the other methods. Using the brush resulted in a significant decrease in the push-out bond strength at the apical side, whereas there was no significant difference in the push-out bond strength between the sites with other tools. Conclusions: It is considered that there is less adherence at the site of air bubbles, and therefore a decrease in the adhesive strength. We conclude that it is important to use a tool that reaches the deepest part of the prepared root canal to reduce the air bubble mixture rate and to obtain the highest adhesive strength.
