“…Generally, the surfaces of RCs are rougher than those of SSCs and milled crowns [31]. In addition, polishing in resin can affect bacterial adherence [32] and owing to the lack of an established RC polishing method, the surface roughness of the crown is higher than that of the SSC surface. Therefore, the index score may be poor.…”

The importance of aesthetics in children has increased over time. Therefore, this multicenter randomized clinical trial aimed to analyze and compare three-dimensional (3D)-printed resin crowns (RCs) as a potential alternative to stainless-steel crowns (SSCs) for restoring primary molars with extensive carious lesions. According to the null hypothesis, no statistically significant difference was observed in restoration failure between RC and SSC groups. A total of 56 primary molars after pulp treatment at two dental hospitals were included. After pulp treatment, the teeth were randomly divided into two groups: SSCs (n = 28) and RCs (n = 28). At 1 week and 3, 6 and 12 months, the Quigley-Hein plaque index (QHI), gingival index (GI), occlusal wear, and survival rate were assessed by examination, radiography and alginate impressions. No significant difference in QHI was observed between the two groups. However, the GI at 12 months and occlusal wear in the RC group were significantly higher than those in the SSC group (p < 0.05). The survival rates were 100% in the SSC group and 82.1% in the RC group (p = 0.047). Cracks and discoloration were also observed in the RCs. Within the limitations of this study, 3D-printed RCs are aesthetically superior to SSCs and clinically easy to repair. However, if clinical effectiveness and safety are improved, RCs could potentially become a viable aesthetic alternative in the future.

“…The synthetic saliva sample was prepared with inorganic components and a thickener, as described in the literature [ 41 ]. Briefly, the synthetic saliva sample were prepared in ultrapure water with the following composition: 1.5 mmol L −1 CaCl 2 , 8.2 mmol L −1 NaHCO 3 , 4.8 mmol L −1 NaCl, 137 mmol L −1 KCl, and 4 mmol L −1 KH 2 PO 4 and 0.5% of carboxmethylcellulose (DS = 0.7)…”

Multiple Pulse Amperometry—An Antifouling Approach for Nitrite Determination Using Carbon Fiber Microelectrodes

et al. 2023

Nitrite is a ubiquitous pollutant in modern society. Developing new strategies for its determination is very important, and electroanalytical methods present outstanding performance on this task. However, the use of bare electrodes is not recommended because of their predisposition to poisoning and passivation. We herein report a procedure to overcome these limitations on carbon fiber microelectrodes through pulsed amperometry. A three-pulse amperometry approach was used to reduce the current decay from 47% (after 20 min under constant potential) to virtually 0%. Repeatability and reproducibility were found to have an RSD lower than 0.5% and 7%, respectively. Tap water and synthetic inorganic saliva samples were fortified with nitrite, and the results obtained with the proposed sensor were in good agreement with the amount added.

“…More precisely, after a thorough investigation of the recent literature concerning biofilm formation on resin-based CAD/CAM blocks for permanent indirect restorations, a total of eleven research articles were found [69][70][71][72][73][74][75][76][77][78][79]. These studies investigated one or more hybrid, resin-based CAD/ CAM materials with regard to biofilm attachment and growth.…”

“…The materials investigated in each study differed. Some researchers solely examined resinbased CAD/CAM blocks [70,[76][77][78]. Others compared resin-based CAD/CAM blocks to conventional composite resins [74], whereas some in vitro research incorporated direct composite resins, indirect CAD/CAM blocks and human enamel [72,73].…”

Hybrid materials are a recent addition in the field of restorative dentistry for computer-aided design/computer-aided manufacturing (CAD/CAM) indirect restorations. The long-term clinical success of modern dental restorative materials is influenced by multiple factors. Among the characteristics affecting the longevity of a restoration, the mechanical properties and physicοchemical interactions are of utmost importance. While numerous researchers constantly evaluate mechanical properties, the biological background of resin-based CAD/CAM biomaterials is scarcely investigated and, therefore, less described in the literature. This review aims to analyze biofilm formation on the surfaces of novel, hybrid, resin-based CAD/CAM materials and evaluate the methodological protocols followed to assess microbial growth. It is demonstrated that the surface structure, the composition and the finishing and polishing procedures on the surface of a dental restorative material influence initial bacterial adhesion; however, most studies focus on in vitro protocols, and in vivo and/or in situ research of microbiomics in CAD/CAM restorative materials is lacking, obstructing an accurate understanding of the bioadhesion phenomenon in the oral cavity.
