DOI: 10.11607/ijp.6428, PubMed ID (PMID): 32956433Pages 523-526, Language: EnglishCekic-Nagas, Isil / Nagas, Emre / Egilmez, Ferhan / Ergun, Gulfem / Vallittu, Pekka / Lassila, LippoPurpose: To investigate the three-point flexural strength of a novel CAD/CAM fiber-reinforced composite (FRC) material following different aging conditions.
Materials and Methods: The specimens were randomly assigned to one of five groups based on aging condition: (1) control (no treatment); (2) short-term water storage; (3) thermal degradation with autoclaving; (4) chemical degradation with hydrochloric acid; and (5) chemical degradation with citric acid (n = 10 per group). The specimens in the control group received no treatment. Following each treatment protocol, the three-point bending test was used to calculate the flexural strength. Data were statistically analyzed (α = .05), and scanning electron microscopy (SEM) analysis of the specimens was conducted.
Results: No significant differences in flexural strength were observed among the groups (P = .199). In addition, no distinct morphologic differences were detected in the SEM images of the specimens.
Conclusion: The flexural strength of this novel CAD/CAM FRC material was unaffected by different aging methods.
