“…On one hand, researchers are exploring the influence of adhesive components on bonding strength, including the types and concentrations of monomers, fillers, and additives (Cramer et al, 2011). On the other hand, optimizing surface treatment processes to enhance bonding strength and further exploring innovative methods such as laser irradiation, air abrasion, and plasma treatment to improve the tooth surface and enhance bonding efficiency are current research focuses (Ye et al, 2022;Liu et al, 2023;Peng et al, 2023). These techniques aim to create a micromechanical interlocking or alter the chemical properties of the tooth structure to enhance bonding strength.…”

Objective: A visual analysis of the literature in the field of dental adhesives is conducted in order to explore the current state of research, cutting-edge areas of interest, and future development trends in this domain.Methods: English literature related to dental adhesives published between 2000 and 2023 was searched in the Web of Science Core Collection database. The retrieved results were then imported into VOSviewer and CiteSpace software in plain text format. Various data, such as journal names, authors, institutions, countries, and keywords, were extracted for further bibliometric analysis.Results: A total of 19,403 publications were retrieved, featuring 42,365 authors, 7,359 institutions, 121 countries, and 1,523 journals. The annual publication and cumulative publication rates in this field are both on the rise. Among them, DENTAL MATERIALS is the journal with the highest publication rate, cumulative publication rate, and number of citations. Ozcan M is the author with the most publications and within the limitations of this study, is considered an influential author in the field (with the highest intermediary centrality score) and Meerbeek B is the author with the highest number of citations. UNIV SAO PAULO is the institution with the highest publication rate. The United States is the country with the highest publication rate and has the most collaborative partnerships with other countries. Collaboration between different authors, institutions, and countries in this field is indeed close, which has greatly contributed to the rapid development of dental adhesives. Current research focuses on various aspects such as the types of dental adhesives, adhesive strength, dental diseases, and clinical trials. Future research directions mainly concentrate on aspects such as nanoparticles, 3D printing, universal adhesives, antibacterial properties of adhesives, and adhesive strength.Conclusion: Within the defined scope of this study, we have conducted a quantitative and objective analysis of the current research status and emerging trends in dental adhesives. This analysis establishes a knowledge foundation and introduces novel perspectives for future in-depth investigations in this field.

The rotor or impeller is a rotational and key part of a pump and compressor. This article presents the detailed development process of a rotor of small size constructed from an EN8 steel cylindrical blank using a novel technique based on a computer numerical control engraving milling machine (CNC-EMM) equipped with a 4 mm tungsten carbide end mill cutter. We fabricated a total of twenty-eight stepped rotors following the Box–Behnken Design (BBD) DoE technique at fourteen distinct combinations of CNC-EMM variable parameters, namely rotational speed, feed, and plunge feed. Average roughness ‘Ra’, an important surface quality indicator, has been considered and presented in this article, as a quality measure for the fabricated rotors. Feed and plunge feed have been identified as the most influencing variable parameters as per an analysis of variance (ANOVA) test. The lowest average roughness value obtained by this process for the rotor blade was 0.11 µm. A micrograph obtained from a field-emission scanning electron microscope (FE-SEM) showed a uniform and accurate tooth profile along with burr formation at corner edges. This study claims to establish engraving milling as a viable alternative to other manufacturing processes used for rotor blades. The findings of this study are useful to scholars, engineers, and researchers who are exploring new ways to fabricate mechanical parts and components.

“…To ensure a secure and strong bond with other dental materials, including resin cement, acrylic resin, and composite resin [ 17 , 18 ], PEEK surfaces require adequate pretreatment, typically mechanical and chemical pretreatments, before bonding [ 19 ]. Mechanical pretreatment typically involves air-abrasion using alumina oxide particles [ 20 , 21 ], with optimal parameters being a blasting pressure of 2 bar and an alumina particle size of 110 μm [ 22 ].…”

Polyetheretherketone (PEEK) is widely used in dentistry owing to its exceptional properties, including its natural appearance; however, existing surface treatment methods for bonding PEEK have limitations. Autofocus laser cutters, known for their precise engraving and cutting capabilities, offer potential for surface treatment of PEEK; thus, the objective of this study was to investigate the creation of laser groove structures on PEEK to enhance its bonding capability with dental resin cement. A dental computer-aided design and manufacturing system was used to fabricate PEEK samples, and three groove patterns (circle, line, and grid) were generated on PEEK surfaces, with air-abrasion used as the control group. The surface characteristics, cell viability, and bond strength were evaluated, and the data were statistically analyzed using one-way analysis of variance and post hoc Tukey’s tests (α = 0.05). Laser-treated PEEK exhibited a uniform texture with a groove depth of approximately 39.4 µm, hydrophobic properties with a contact angle exceeding 90°, a surface roughness of 7.3–12.4 µm, consistent topography, and comparable cell viability compared with untreated PEEK. Despite a decrease in bond strength after thermal cycling, no significant intergroup differences were observed, except for the line-shaped laser pattern. These findings indicate that the autofocus laser cutter effectively enhances the surface characteristics of PEEK by creating a uniform texture and grooves, showing promise in improving bonding properties, even considering the impact of thermal cycling effects.
