Abstrakt:	Objectives: The purpose of this study was to compare the retention properties between fiberglass pins with chemically activated acrylic resin and metallic intraradicular retainers often used for the purpose of temporary prosthetic retention. Materials and Methods: Two mechanical tests, pushout and traction, were performed on specimens distributed in three groups ( n = 10) for each test; two metal pins G1: Metalpin Ângelus and G2: Provisional Pivot Jon in addition to one fiberglass pin G3: Whitepost DC-E, FGM. One-way analysis of variance (ANOVA) followed by Tukey's post hoc test was used at the level of significance α = 0.05. Results: The fiberglass pins (G3) showed higher values in the traction test than the metal pins (G1 and G2) with a statistically significant difference ( P < 0.05); however, they performed similarly to the metal pin groups in the pushout test ( P > 0.05). They also presented a lower occurrence of failure in the relining acrylic resin. Conclusion: The study pointed out the use of fiberglass pins as suitable alternatives for provisional intracanal metallic retainers. Competing Interests: There are no conflicts of interest.
