Abstract :Objective: The longevity of dental restorative materials is a critical factor for successful clinical outcomes. This study aims to analyze the aging protocols used to evaluate the performance of restorative materials under oral conditions, discuss the strengths and limitations of these methods, and highlight the need for new protocols that provide improved simulation. Materials and Methods: Aging protocols have been developed to mimic oral conditions such as temperature fluctuations, pH changes, enzymatic activity, and mechanical forces. Commonly used methods include water storage, sodium hypochlorite (NaOCl) exposure, pH cycling, thermal cycling, and chewing simulation. These techniques focus on assessing specific performance properties, such as hydrolytic degradation, chemical resistance, thermal stability, and mechanical wear. Results: Each aging method provides valuable insights into the durability of restorative materials. However, current protocols often fail to fully replicate the complex and multifactorial environment of the oral cavity. This highlights the need for more sophisticated protocols that better simulate clinical conditions. Conclusion: Evaluating the advantages and limitations of existing aging methods underscores the necessity for developing more accurate and reliable protocols for clinical simulation. This advancement would enhance the durability and clinical efficacy of restorative materials, promoting long-term success.
