From Surface to Interface: Understanding Staining and Fatigue of Direct and Indirect Restorations

Featuring:

Vesna Miletic (University of Sydney, Australia)

This talk summarizes the effects of staining and aging on the optical properties of contemporary restorative materials. Across resin cements, composites, and gingiva-colored materials, optical properties were consistently found to be material- and condition-dependent. Factors such as resin cement translucency, type of dentin replacement, staining medium (e.g., red wine, coffee, tea), and aging duration significantly influenced final appearance. Highly translucent restorative materials particularly affected colour changes and appearance of restorations. While bulk-fill and universal composites performed comparably in some cases, sorption, solubility, and dentin replacement materials impacted optical outcomes. Some bioflavonoid-containing mouth rinses showed promise for reducing staining effects compared to traditional chlorhexidine. Clinically, these findings underscore the need for careful material selection and aesthetic layering to ensure long-term stability of appearance in restorations exposed to common dietary and oral hygiene conditions.

Nicola Scotti (University of Turin, Italy) 

In adhesive restorative dentistry, maintaining marginal integrity remains a key clinical challenge. Gaps at the tooth-restoration interface could compromise the long-term success, often leading to marginal staining, secondary caries, sensitivity, and restoration failure. A critical  factor contributing to this deterioration is cyclic fatigue induced by repetitive occlusal loading over time. Cyclic fatigue progressively undermines the stability of the adhesive interface, especially in high-stress areas, weakening the hybrid layer and promoting interfacial degradation. In vitro studies simulating physiological loading conditions have provided insight into the fatigue behavior of different adhesive systems and direct/indirect restorative materials. Understanding the pathways of fatigue-induced damage is essential for the development of more durable restorative strategies and can inform clinical insights aimed at proper clinical interpretation of the marginal gap.
