The aim of this study was to investigate whether resin core build-ups with glass fiber posts were less likely to cause root fractures than metal post cores, as well as to determine appropriate pretreatment methods for fiber posts and cavities of root canal dentin.
In a systematic review and meta-analysis, the survival and success rates of prostheses using fiber or metal posts were found to differ, with fiber posts displaying higher survival rates or no significant difference between the two. Additionally, the references showed variations in root fractures and secondary caries, with fiber posts exhibiting significantly fewer occurrences or no significant differences.
Silane treatment for fiber posts was determined to be ineffective, while air-abrasion with alumina at 0.15 MPa was found to be effective in bonding resin to fiber posts. As for the pretreatment of root canal dentin cavities, it is recommended to use a combination of phosphoric acid, sodium hypochlorite, and antioxidant sulfinates, followed by a one-step self-etching primer or bonding resin.
