Study on the Behaviour of the Luting Cement for Aesthetic Inlays

Abstract

The clinical success of any indirect prosthodontic restoration is strongly related, among other numerous factors, to the fixing procedure. The technological deficiencies into the inlay cementation lead to defects, either in depth or on surface, which often cause failures. The longevity of inlays depends, to a large extent, on the quality of the dental-prosthetic joint. This marginal adaptation is influenced by the thickness and the type of the luting cement. The aim of this study is a comparative analysis on the behavior of the luting cement for composite resin and ceramic inlays in two different solutions: ANFOR-type artificial saliva and a 20% citric acid solution. Fixing composites are the material of choice for works with high aesthetic potential, our study revealing that their depreciation and alteration is reduced, even in aggressive environments. Cementation seems to be the most critical step, and its long-term success relies on adherence to the clinical protocols.

Metal leaching from antimicrobial cloth face masks intended to slow the spread of COVID-19

“…In the case of a face mask covering the mouth, the environment is warm air/CO 2 , humidified by saliva, a fluid with known antioxidant properties. Fusayama artificial saliva solution (denoted saliva F; pH = 5) 59 and Anfor saliva solution (denoted saliva A; pH = 6.7) 60 were used as a simulated leaching fluid for as-received masks. Artificial saliva solutions were mixed in house by dissolving and vortexing the following compounds in Milli-Q water; saliva F contained NaCl (0.4 g/L), KCl (0.9 g/L), CaCl 2 ⋅2H 2 O (0.795 g/L), NaH 2 PO 4 (0.69 g/L), and urea (1 g/L), and saliva A contained NaCl (0.7 g/L), KCl (1.2 g/L), Na 2 HPO 4 (0.26 g/L), NaHCO 3 (1.5 g/L), KSCN (0.33 g/L), and urea (1 g/L).…”

Metal Leaching from Antimicrobial Cloth Face Masks Intended to Slow the Spread of COVID-19

“…Fusayama arti cial saliva solution (denoted saliva F; pH = 5) was used as a simulated leaching uid for both as-received masks and washed masks 41 . As received masks were also exposed to Anfor saliva solution (denoted saliva A; pH = 6.7) 42 . While Fusayama solution is one of the most commonly used in the evaluation of dental implants, the composition of human saliva is known to vary widely, with the calcium component in Fusayama tempering the oxidant nature of the more pro-oxidant Anfor solution 43 .…”

Development of nystatin‐based antifungal, biodegradable polymer composite materials for food packaging via melt processing approach

“…All PHA films prevented biofilm formation against C. albicans , although they proved inefficient in eliminating mature biofilms. Bargan et al synthesized hydroxyapatite and nystatin‐based cellulose acetate composites via phase inversion, which exhibited improved local therapeutic effects in candidiasis therapy 29 . The nystatin‐based composites exhibited a strong inhibition effect on the Candida albicans growth, suggesting their clinical potential application with a great appeal toward the treatment of localized infections.…”
