A bibliometric and Altmetric analysis of the 100 top most cited articles on dentin adhesives.

OBJECTIVE: This study aimed to identify the 100 top-cited articles on dentin adhesives utilizing comprehensive bibliometric and altmetric analyses. MATERIALS AND METHODS: The Institute of Scientific Information Web of Knowledge database was used to compile the top-cited articles published from 1945 through February 12, 2023. Citation counts were manually retrieved for each article from Scopus, Google Scholar, Dimensions, and Altmetric. The articles were analyzed in terms of their number of citations, year, journal name, author (name, institution, and country), and type and specific field of study. We used descriptive statistics to summarize the results. RESULTS: The analysis revealed that the top 100 cited articles originated from 18 English-language journals and collectively accumulated a remarkable 34526 citations. The article with the highest number of citations garnered 1288 references. Among authors, Van Meerbeek B. stood out with nine articles and 4650 citations, followed by Pashley D.H. with six articles and 2769 citations. Japan was the leading contributor by country, while the Catholic University of Leuven led in terms of institutions with 20 articles. CONCLUSION: According to this study, basic research and review articles garnered the most citations, respectively. The citation analysis revealed different trends for researchers, the first being that researchers have focused on basic fields such as the ultramorphology of dentin and adhesive interfaces, followed by bond strength to dentin. Two studies on clinical experiences suggested that studies with high-level evidence, such as systematic reviews, meta-analyses, or randomized controlled clinical trials, are required. CLINICAL RELEVANCE: It is identified that more studies with high-level evidence-based research are needed in the field of dental adhesives.

The prevalence, clinical features, and related factors of dentin hypersensitivity in the Turkish population.

OBJECTIVES: The purpose of this study was to identify the prevalence and predisposing and etiologic factors of dentin hypersensitivity (DH), as well as the demographic characteristics of patients. MATERIALS AND METHODS: The 1210 patients were examined. The research was based on a two-step investigation: questionnaire and clinical examination. DH was evaluated by the response of the patient to tactile and air-blast stimuli. Loss of attachment and gingival recession of sensitive teeth was measured on the buccal and lingual surfaces. Also, the tooth wear of sensitive teeth was graded on the buccal and lingual surfaces. Comparisons of nonnormally distributed continuous variables were performed using the Mann-Whitney U test and Kruskal-Wallis one-way analysis of variance (ANOVA) and Dunn's post hoc test. Comparisons of categorical variables were performed using Pearson's chi-square, Fisher's exact chi-square, Yates's chi-square, and the Monte Carlo chi-square test. RESULTS: One hundred twenty-four patients reported DH, showing a prevalence for self-reported DH of 10.2%. Eight hundred forty teeth were diagnosed as having DH, giving a clinical diagnosis rate of DH of 29.4%. Females (76.8%), the 31-40 years age group (26%), housewives (36.8%), and high school education level (38%) had the highest prevalence of DH as demographic properties. A cold stimulus was the most common stimuli trigger for hypersensitivity (97.1%). Occasional pain (55.5%) showed the highest prevalence in terms of frequency of DH. A higher rate of DH was found with the use of medium brushes (47.4%) and brushing twice per day (59.4%) for 1-2 min (56.2%) with the circular method (33.8%) as oral hygiene habits. The buccal surface of the lower right central incisors (5.7%) had the highest prevalence. The most affected teeth by DH were incisors (38.4%). The buccal surfaces (86.3%) of teeth showed a higher high prevalence of DH compared with the lingual surface (52.7%), similar to gingival recession (40.9% vs. 15.7%) and loss of attachment (68.3% vs. 42.6%). CONCLUSIONS: Clinically diagnosed DH was more common than self-reported DH. Some factors related to patients such as sex (female), the 31-40 years age group, housewives, high school students, using medium brushes, brushing twice per day, and the circular brushing method were more likely to have a risk for DH. Also, buccal surfaces of teeth, gingival recession, and loss of attachment on the buccal surface of teeth should be considered as predisposing factors for DH. CLINICAL RELEVANCE: To control and prevent DH, clinicians should consider patients' demographics, predisposing factors, and etiologic factors.

Microtensile Bond Strength Between Self-Adhesive Resin Cements and Resin Based Ceramic CAD/CAM Block / Resistencia adhesiva microtensil entre cementos de resina autoadhesivos y bloques de cerámica CAD/CAM a base de resina

Abstract: Purpose: The objective of this study is to evaluate and compare the microtensile bond strength (μTBS) of four different self-adhesive resin cements to a resin-based ceramic CAD/CAM block, at the baseline, and after subjecting them to 5,000 thermo-cycles.Materials and Methods: Four self-adhesive dual-cured resin cements; G-CEM LinkAce (GC EUROPE, Leuven, Belgium), RelyX U200 (3M ESPE, Seefeld, Germany), Maxcem Elite (Kerr, CA, USA), TheraCem (Bisco, Schaumburg, USA) were applied to Cerasmart CAD/CAM blocks (GC EUROPE, Leuven, Belgium). CAD/CAM blocks were sectioned into sticks and subjected to µTBS tests at 24 hours, and the other half were subjected to tests after 5000 thermo-cycles. The data were tested by one-way variance analysis (p<0.05). Results: The highest bond strength values were observed in TheraCem, followed by G-CEM LinkAce and RelyX U200, respectively (p<0.05). At the baseline, G-CEM LinkAce, RelyX U200, and Maxcem Elite showed statistically similar results. After 5,000 thermal-cycles, a significant decrease was observed in the bond strength values of G-CEM LinkAce (p<0.05). Conclusion: Between the adhesive cements used in the study, TheraCem showed the highest micro-tensile bond strength values both in the baseline (24h) results, and after the 5,000 thermal- cycle aging procedures.

Resumen: Propósito: Evaluar y comparar la resistencia adhesiva microtensil (μTBS) de cuatro cementos de resina autoadhesivos diferentes con un bloque CAD/CAM de cerámica a base de resina, antes y después de 5.000 ciclos de termociclado. Materiales y métodos: cuatro cementos de resina de doble curado autoadhesivos; G-CEM LinkAce (GC EUROPE, Lovaina, Bélgica), RelyX U200 (3M ESPE, Seefeld, Alemania), Maxcem Elite (Kerr, CA, EE. UU.), TheraCem (Bisco, Schaumburg, EE. UU.) fueron aplicados a bloques Cerasmart CAD/CAM (GC EUROPE, Lovaina, Bélgica). Los bloques CAD/CAM se seccionaron en barras y se sometieron a pruebas µTBS a las 24 horas, y la otra mitad se sometió a pruebas después de 5000 ciclos térmicos. Los datos fueron probados por análisis de varianza unidireccional (p<0.05). Resultados: Los valores más altos de fuerza de unión se observaron en TheraCem, seguido de G-CEM LinkAce y RelyX U200, respectivamente (p<0.05). En la línea de base, G-CEM LinkAce, RelyX U200, Maxcem Elite mostró resultados estadísticamente similares. Después de 5.000 procesos de ciclo térmico, se observó una disminución significativa en los valores de resistencia de la unión de G-CEM LinkAce (p<0.05). Conclusión: entre los cementos adhesivos utilizados en el estudio, TheraCem mostró los valores más altos de resistencia de la unión micro-extensible tanto en la línea de base (24 h) como después de 5,000 procedimientos de envejecimiento térmico.
