    In contemporary restorative dentistry, short-fiber reinforced composite (SFRC) frequently serves as a dentin replacement material. However, its mechanical limitations within the harsh oral environment often necessitate restorative repairs over time. Because validating the durability of these repairs requires artificial aging methods that accurately mimic intraoral conditions, this study evaluates and compares the effects of thermocycling and long-term water storage on microtensile repair bond strength. The comprehensive in vitro methodology encompassed specimen preparation, surface treatment, composite repair, load testing, artificial aging, and subsequent statistical analysis of the bond strength. Results demonstrated no statistically significant differences in microtensile bond strength between the two aging methods. Consequently, thermocycling is established as the superior experimental protocol, offering a reliable assessment of SFRC repair durability within a significantly condensed timeframe.
