The influence of a continuous increase in thickness of opaque-shade composite resin on masking ability and translucency

Abstract

The brands and shades of the composite resins were shown to have a clear effect on TP, but an inconsistent tendency for ΔE*(ab).

Translucency of esthetic dental restorative CAD/CAM materials and composite resins with respect to thickness and surface roughness

“…Whether a linear or exponential relation exists within a clinical relevant thickness of 1 to 2 mm is unclear. 22,29,30 Moreover, the total refractive index is directly related to the thickness of the material. The loss of translucency in the case of increased thickness is of clinical relevance.…”

“…[24][25][26][27][28] Accurate knowledge of the relationship between translucency and thickness and surface roughness is fundamental to improving the esthetic outcome of dental restorations. 22,29,30 The null hypotheses tested were that material thickness would not affect translucency; that the pretreatment method (roughening) would not affect translucency; and that the material type would not affect translucency.…”

Translucency and masking properties of two ceramic materials for heat‐press technology

“…The appearance of a full‐ceramic restoration is influenced by the color of the underlying tooth structures, the color, and thickness of the luting cement, the color and optical properties of the restorative material, surface texture, and glaze . The thickness of the restorative material is also contributing to the outcome of the restoration and there are studies demonstrating the close relationship between the masking effect and thickness . However, there are certain situations in practice, particularly in the case of discolored teeth, when a large amount of tooth structure cannot be removed without jeopardizing the vitality of teeth.…”

Review of Translucency Determinations and Applications to Dental Materials

“…Using straight‐line light transmittance calculated from the peak gain at an angle of zero degrees, and the transmitted light diffusion property calculated as the diffusion factor, combinations of composite materials were studied with and without TP determinations. Thickness effects were well noted for dental composite materials. Staining effects were verified using transmittance and TP determinations.…”
