Survival rates of a novel intra-canal fiber post system: a retrospective comparative cohort study.
Article in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThis retrospective cohort study aimed to evaluate the survival rates of a novel fiber post system designed to adapt to the shape of the canal and to compare it with a parallel-shaped post system featuring stepped grooves. MATERIALS AND
methodsThe survival rates of cases with service periods ranging from 12 to 48 months were assessed using diagnostic, post-treatment, and routine periodic control radiographs of teeth restored with either Splendor SAP or Reforpost. A total of 220 patients were randomly selected from the patient database and included in the study. Radiographs and clinical records were evaluated based on parameters such as tooth type, coronal restoration, and vertical and horizontal fiber post adaptation. The survival rates and radiographic outcomes of the two fiber post systems were analyzed using Pearson's chi-square test, McNemar's analysis, Kaplan-Meier analysis and logistic regression analysis (p = 0.05).
resultsThe Splendor SAP group exhibited a slightly higher survival rate (99.1%) compared to the Reforpost group (96.4%) (p > 0.05). However, Splendor SAP demonstrated superior vertical and horizontal adaptation (p < 0.05). Kaplan-Meier analysis revealed similar survival rates (p = 0.281), and tooth type, localization, and restoration type did not significantly affect survival (p > 0.05).
conclusionsThe findings suggest that both Splendor SAP and Reforpost systems show high survival rates, with Splendor SAP potentially offering advantages in post adaptation. However, further clinical studies are needed to validate these findings and assess the long-term performance of the novel fiber post system. CLINICAL RELEVANCE: The Splendor SAP fiber post system exhibited favorable outcomes compared to the Reforpost system in terms of coherence and survival rates based on radiographic analyses. It may be particularly advantageous for canals with excessive flare and/or an oval cross-section.
