This systematic review aimed to investigate the fracture resistance and mode of failure of endodontically-treated permanent teeth restored with Ribbond posts (Ribbond, Inc.) compared with endodontically-treated permanent teeth restored with other post systems.
Methods
A comprehensive, systematic literature search was carried out using several electronic databases: MEDLINE/PubMed, Google Scholar, and Cochrane Library. Two separate researchers were appointed to identify the studies meeting the eligibility criteria, and to perform the data extraction, risk of bias, and quality assessment.
Results
Twelve studies were included in the quantitative analysis. Meta-analysis was performed with 11 of the 12 included articles. The meta-analysis showed that Ribbond posts have a fracture strength less than prefabricated metal posts, cast metal posts, and prefabricated fiber posts and greater than custom e-glass fiber posts. Mode of failure analysis revealed that Ribbond posts have the most favorable non-catastrophic fractures.
Conclusions
Although Ribbond posts have lower fracture resistance, their favorable mode of failure makes them potentially the most biomimetic post system.

Objectives The purpose of this study was to compare the microshear bond strength (uSBS) of two total-etch and four self-etch adhesive systems and a flowable resin to enamel.
Materials and Methods Enamels of sixty human molars were used. They were divided into one of six equal groups (
n = 10) by adhesives used; OS group (One-Step Plus), SB group (Single Bond), CE group (Clearfil SE Bond), TY group (Tyrian SPE/One-Step Plus), AP group (Adper Prompt L-Pop) and GB group (G-Bond).After enamel surfaces were treated with six adhesive systems, a flowable composite resin (Filek Z 350) was bonded to enamel surface using Tygon tubes. the bonded specimens were subjected to uSBS testing and the failure modes of each group were observed under FE-SEM.
Results 1. The
u SBS of SB group was statistically higher than that of all other groups, and theu SBS of OS, SE and AP group was statistically higher than that of TY and GB group (p < 0.05).2. The
u SBS for TY group was statistically higher than that for GB group (p < 0.05).3. Adhesive failures in TY and GB group and mixed failures in SB group and SE group were often analysed. One cohesive failure was observed in OS, SB, SE and AP group, respectively.
Conclusions Although adhesives using the same step were applied the enamel surface, the uSBS of a flowable resin to enamel was different.
