Resin composite thickness' influence on L*a*b* coordinates and translucency

Clinical Oral Investigations

Abstract

To evaluate if material thickness can influence the L*a*b* coordinates and translucency of different composite shades. Twelve composite disc specimens made of three different resin composite materials (dentin A2, Essentia, GC; body shade A2, Brillant Everglow, Coltene-Whaledent; enamel skin neutral, Inspiro, Edelweiss DR) and of three different thicknesses 0.5, 1.0, and 1.5 mm were readied. L*a*b* coordinates of the 118 specimens were assessed by a calibrated reflectance spectrophotometer over a black as well as a white background. Over the black background, median ΔE00 values varied from 0.7 (Brilliant Everglow) to 1.5 (Inspiro SN) for 0.5-mm composite thickness (intrinsic color variation) and from 3.2 (Essentia) to 7.5 (Inspiro SN) for 1.0 mm, respectively 6.1 (Essentia) to 11.1 (Inspiro SN) for 1.5-mm composite thickness (color variation related to thickness). Over the white background, median ΔE00 values varied from 0.6 (Essentia) to 1.6 (Inspiro SN) for 0.5-mm composite thickness and from 2.9 (Inspiro SN) to 4.3 (Essentia) for 1.0 mm, respectively 4.9 (Inspiro SN) to 7.0 (Essentia) for 1.5-mm composite thickness. Transparency varied from 25.2% (Essentia) to 34.6% (Inspiro SN) for 0.5-mm composite thickness, from 20.3% (Ess...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
