O EFEITO FÉRULA TEM INFLUÊNCIA NA OCORRÊNCIA DE FALHA E SOBREVIDA EM DENTES COM RESTAURAÇÕES RETIDAS POR PINO DE FIBRA? REVISÃO DE LITERATURA
Bibliographic record
Abstract
This study aimed to perform a literature review about the influence of the ferula effect on the occurrence of failure and clinical survival of fiber-reinforced composite post-andcore restorations. A search was performed in the PubMed / MEDLINE, Scopus and Cochrane Library databases. A search strategy centered on terms related to DM and PA was used, using the following MESH terms: "Ferrule", "Ferrule effect", "Fiber posts" and "Post and Core Technique". Articles published until July 2019 were reviewed. After the search, it was possible to observe only 4 clinical studies investigating the influence of the ferula effect on the occurrence of failure and clinical survival of fiber-reinforced composite post-and-core restorations. It was observed that the preservation of at least one coronary wall helped to reduce the occurrence of failures and increase the survival of teeth restored using fiber posts. In addition, fiber post placement also made a significant contribution to failure and survival rates. Survival rates ranged from 72.5% to 95% in the teeth with ferula groups and from 62.5% to 95.2% in the groups without ferula effect. However, only one study showed difference in survival of restored teeth, with the ferula effect favoring survival. Thus, it was possible to conclude that the ferula effect does not seem to significantly influence the reduction of failure rates and the increased survival of fiber-reinforced composite post-and-core restorations. However, there are still few studies related to this subject, requiring well-designed clinical trials.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
