Non-metal carbon-fibre post and core (Category III; Composipost) vs Metal custom-cast post and core (Category I): Clinical/technical failure (root fracture)
- Population
- Participants with permanent endodontically-treated (root-filled) teeth for which a post is indicated to retain the final restoration
- Intervention
- Non-metal carbon-fibre post and core (Category III; Composipost)
- Comparison
- Metal custom-cast post and core (Category I)
- Outcome
- Clinical/technical failure (root fracture)
Non-metal carbon-fibre post and core (Category III; Composipost) led to lower clinical/technical failure (root fracture) compared with metal custom-cast post and core (Category I; gold alloy); GRADE not reported.

How reviews are matched to this question
Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
