Stress distributions at dentine–composite interface from occlusal (a) and distal (b) surfaces. Both tensile and compressive stresses (MPa) concentrations are shown at the dentine–enamel junction. CPRESS (contact pressure) indicates interfacial stress, positive values indicate interfacial compressive stress while negative indicate interfacial tensile stress. The interfacial tensile stress contributes most to debonding
