Artificial Intelligence-Related Dental Research: Bibliometric and Altmetric Analysis.

BACKGROUND: Recent years have witnessed an explosive surge in dental research related to artificial intelligence (AI). These applications have optimised dental workflows, demonstrating significant clinical importance. Understanding the current landscape and trends of this topic is crucial for both clinicians and researchers to utilise and advance this technology. However, a comprehensive scientometric study regarding this field had yet to be performed. METHODS: A literature search was conducted in the Web of Science Core Collection database to identify eligible "research articles" and "reviews." Literature screening and exclusion were performed by 2 investigators. Thereafter, VOSviewer was utilised in co-occurrence analysis and CiteSpace in co-citation analysis. R package Bibliometrix was employed to automatically calculate scientific impacts, determining the core authors and journals. Altmetric data were described narratively and supplemented with Spearman correlation analysis. RESULTS: A total of 1558 research publications were included. During the past 5 years, AI-related dental publications drastically increased in number, from 36 to 581. Diagnostics and Scientific Reports published the most articles, whereas Journal of Dental Research received the highest number of citations per article. China, the US, and South Korea emerged as the most prolific countries, whilst Germany received the highest number of citations per article (23.29). Charité Universitätsmedizin Berlin was the institution with the highest number of publications and citations per article (29.16). Altmetric Attention Score was correlated with News Mentions (P < .001), and significant associations were observed amongst Dimension Citations, Mendeley Readers, and Web of Science Citations (P < .001). CONCLUSIONS: The publication numbers regarding AI-related dental research have been rising rapidly and may continue their upwards trend. China, the US, South Korea, and Germany had promoted the progress of AI-related dental research. Disease diagnosis, orthodontic applications, and morphology segmentation were current hotspots. Attention mechanism, explainable AI, multimodal data fusion, and AI-generated text assistants necessitate future research and exploration.

Amorphous-Crystalline Heterostructured Nanoporous High-Entropy Alloys for High-Efficiency pH-Universal Water Splitting.

Developing high-efficiency durable electrocatalysts in wide pH range for water splitting is significant for environmentally-friendly synthesis of renewable hydrogen energy. Herein, a facile method by dealloying designable multicomponent metallic glass precursors is reported to synthesize amorphous-crystalline heterostructured nanoporous high-entropy alloys (AC-HEAs) of CuAgAuPtPd, CuAgAuIrRu, and CuAgAuPtPdIrRu, heaped up by nanocrystalline particles with an average size of 2-3 nm and the amorphous glued phase. The synthesized AC-HEA-CuAgAuPtPd owns highly catalytic performances for hydrogen evolution reaction (HER), with 9.5 and 20 mV to reach 10 mA·cm-2 in 0.5 m H2SO4 and 1.0 m KOH, and AC-HEA-CuAgAuIrRu delivers 208 and 200 mV for oxygen evolution reaction (OER). Moreover, a two-electrode electrolyzer made of the AC-HEA-CuAgAuIrRu bifunctional electrodes exhibit a low cell voltage of 1.48 and 1.49 V in the acidic and alkaline conditions at 10 mA·cm-2 for overall water splitting. Combining the enhanced catalytic activities from nanoscale amorphous structure and atom-level synergistic catalyst in AC-HEAs provides an effective pathway for pH-universal electrocatalysts of water splitting.

Self-adhesive flowable composite resins and flowable composite resins in permanent teeth with occlusal cavities: A systematic review and meta-analysis.

OBJECTIVES: To compare the clinical performance (retention, secondary caries, marginal adaptation, marginal discoloration, and postoperative hypersensitivity) of self-adhesive flowable composite resins (SAFCs) and flowable composite resins (FCs) in permanent teeth with occlusal cavities. DATA: Randomized controlled trials (RCTs) of SAFCs versus FCs with a follow-up length of at least one year. No restrictions were placed on language or publication date. SOURCES: Five databases, including PubMed, Embase, Web of Science, Scopus, and the Cochrane Central Register of Controlled Trials, were searched manually by browsing ten related journals. On 14 June 2023, all electronic and manual searches were updated. STUDY SELECTION: Five RCTs with 138 participants were included. Cochrane's risk of bias tool (2.0) was implemented in selected studies, and the GRADE tool was utilised to evaluate the evidence quality. To summarize the effects of the treatments and pool the data, a random-effects model was used. CONCLUSIONS: According to the modified United States Public Health Service Evaluation (USPHS) criteria, there was no discernible difference between the groups during the two-year follow-up period (maximum follow-up time). Nevertheless, FCs applied with the etch-and-rinse mode demonstrated superior marginal adaptation and marginal discoloration at the two-year follow-up (relative risk = 3.21 [1.50 to 6.83], 3.40 [1.10, 10.48]). The evidence for marginal discoloration at any recall time and marginal adaptation at the one-year follow-up was graded as moderate quality due to inconsistency. Moreover, low-quality evidence for marginal adaptation at two-year follow-up was due to imprecision and inconsistency. CLINICAL SIGNIFICANCE: SAFCs exhibited clinical performance comparable to that of FCs in occlusal cavities. Further high-quality clinical trials are needed to provide solid evidence to support the clinical application of SAFCs. REGISTRATION: PROSPERO (CRD42022374983).

THE CONTENTS, METHODS, AND ASSESSMENT OF EVIDENCE-BASED DENTISTRY EDUCATION: A SCOPING REVIEW.

OBJECTIVE: With evidence-based dentistry (EBD) having a far-reaching influence on oral healthcare, dental educators worldwide have made joint efforts to integrate EBD-related knowledge and skills into dental education. The present scoping review aims to identify and summarize the existing teaching contents, teaching methods, and assessment strategies of EBD education. METHODS: Electronic (PubMed and Embase) and manual searches were performed to identify articles related to both "dental education" and "evidence-based practice." Based on predetermined eligibility criteria, articles were selected by 2 reviewers, independently and in duplicate. Data synthesis was conducted based on teaching contents, teaching strategies, and teaching assessment. RESULTS: Of the 1758 articles found in the literature searches, 74 were deemed eligible and included in this review. A total of 4 basic skills (problem formulation, literature searching, critical appraisal, and research methodology), 5 teaching methods, and 6 assessment strategies were identified. In most of the articles, 2, or more skills were taught, and a combination of traditional strategies for teaching and its assessment (eg, courses and questionnaire survey) was involved. Other teaching methods, such as journal clubs and workshops, were seldom used, and validated assessment tools accounted for a relatively small proportion of the assessment strategies involved. CONCLUSIONS: The contents, methods and assessment of EBD education have been widely studied and discussed. However, the current literature focuses mainly on teaching of critical appraisal skills, traditional teaching methods, and short-term outcome assessments. Future research in this area can be aimed at integrating all EBD-related skills into educational models, studying multifaceted teaching approaches, and developing comprehensive teaching outcome assessment methods based on validated tools and dental patient-reported outcomes.

A Bibliometric Mapping Study of the Literature on Oral Health-related Quality of Life.

BACKGROUND: Oral health is an indispensable component of overall health, and oral health status significantly influences people's physical, mental, and social well-being. Oral health-related quality of life (OHRQoL), an important and widely used dental patient-reported outcome (dPRO), is attracting more and more researchers' attention and interest. This study aimed to analyze and map the existing scientific literature regarding OHRQoL through a bibliometric approach, including a summary of the characteristics of OHRQoL-related publications, the identification of prolific entities, high-frequency keywords analysis, and research trend analysis via periodic high-impact keywords. METHODS: A literature search was conducted in the Web of Science Core Collection to collect OHRQoL-related original research and review articles. After examination and deduplication, the following bibliometric information was extracted from each article: title, abstract, keywords, authors, affiliations, geographic origin (countries/regions), year of publication, journal name, and references. Various scientometric mapping tools including Microsoft Office spreadsheet, VOSviewer, Biblioshiny R-package software, and Scimago Graphica were used to analyze basic bibliometric parameters, leading producers, high-impact keywords, and research trends. RESULTS: A total of 3324 OHRQoL-related articles (3119 original research articles and 205 review papers) were collected, which received 65,704 citations. A total of 9950 authors from 2429 organizations contributed to this body of research. Prolific authors from Europe, USA, Brazil, New Zealand, China, and Canada were identified, and they also centered collaboration clusters in the co-author network. Community Dentistry and Oral Epidemiology was the most prolific journal. Twenty-one keywords with more than 200 occurrences, and 23 keywords with more than 150 occurrences, were identified for publications of 1994-2021 and 2012-2021, respectively. Keyword analysis revealed hot topics such as instrument development and validation, studies targeting children and adolescents, as well as clinical studies in operative dentistry, implantology, orthodontics, and community dentistry. Oral Health Impact Profile is the most commonly used instrument in OHRQoL-related research. CONCLUSIONS: OHRQoL is an impactful topic in dental health care as it is not only useful in dental research and patient-centered clinical outcome measures but also provides valuable guidance in dental public health administration and policy making. OHRQoL-related research presents a dynamic landscape and is expected to continue presenting high productivity and broad application in the future.

Association between sleep-disordered breathing and periodontal diseases: A systematic review protocol.

Background: Sleep-disordered breathing (SDB) is a chronic sleep-related breathing disorder, considered associated with increased risk of cardiovascular disorders, metabolic disorders, cognitive dysfunction and behavior changes. Periodontal diseases are chronic infectious diseases that are also believed to be associated with cardiovascular diseases, metabolic syndrome and cognitive dysfunction. Several studies have indicated that SDB may be associated with periodontal diseases through certain mechanisms such as inflammation response, oxidative stress and oral dryness. The aim of this systematic review is to explore the association between SDB and periodontal diseases in an integrated approach. Materials and Methods: This systematic review will include cohort studies, cross-sectional studies and case-control studies that are identified by electronic and manual searches. Electronic searches will be conducted in the following databases: PubMed, Embase, Scopus and Web of Science. Our search will cover articles published from inception of databases to March 2022 without restrictions in language and settings. Pre-determined eligibility criteria include: participants (participants without a history of respiratory diseases, history of periodontal treatment within the past 6 months and history of medication that is known to influence SDB or periodontal diseases); exposure (participants who have been diagnosed with SDB or at high-risk for SDB); comparison (participants without SDB); and outcome (periodontal parameters, such as probing depth, clinical attachment level, bleeding on probing, radiographic bone loss). Two authors will perform study screening and data extraction independently and in duplicate. All discrepancies will be solved by discussion. The methodological quality of included studies will be assessed using the Newcastle-Ottawa Scale. Discussion: This systematic review will summarize the existing evidence on the association between SDB and periodontal diseases, a topic of controversy and clinical significance. Its findings can provide evidence for the development of relevant prevention and treatment strategies. The results will be disseminated through peer-reviewed journals.

The long-term influence of Open Access on the scientific and social impact of dental journal articles: An updated analysis.

OBJECTIVES: To investigate whether dental journal articles that are Open Access (OA) receive greater citation counts and higher Altmetric Attention Scores (AAS) than articles that are non-OA in the long term. METHODS: Eligible dental journal articles published in 2013 were identified via PubMed, and Web of science, Unpaywall and corresponding URLs were manually checked to determine the OA status of each included article 7 years after publication. Citation counts were extracted from Web of Science and Scopus, and AAS was harvested from the Altmetric Explorer. Multivariable general linear regression analyses were performed to investigate the association between OA and citation count, as well as between OA and AAS. RESULTS: Among the 755 included articles, 309 (40.9%) were freely available online. Among the 309 OA articles, articles available from publishers accounted for 64.4% (199/309) of all OA articles, and those available through self-archiving accounted for 56.0% (173/309). According to regression analyses, OA articles had significantly greater citation counts (P = 0.001) and AAS (P < 0.001) than non-OA articles. CONCLUSIONS/CLINICAL SIGNIFICANCE: In the field of dentistry, about 41% of journal articles are OA 7 years after publication, and OA articles available from the publishers are more common than those from authors through self-archiving. OA articles tend to have greater scientific and social impact than non-OA articles in the long term.

The additional benefit of professional fluoride application for children as an adjunct to regular fluoride toothpaste: a systematic review and meta-analysis.

OBJECTIVE: To assess whether professional fluoride application (PFA) used in addition to regular fluoride toothpaste (RFT, ≥ 1,000 ppm) is more effective than RFT alone in children. MATERIALS AND METHODS: A systematic search was conducted using the PubMed, Embase, Google Scholar and CENTRAL databases. Randomized controlled trials (RCTs) comparing the effectiveness of RFT + PFA and RFT alone were included. Meta-analyses with random-effects models were performed. The certainty of evidence was assessed using the GRADE approach. RESULTS: A total of 2,729 records were identified from electronic and manual searches, which were screened by two reviewers independently and in duplicate. Six RCTs (5,034 participants) were included, of which four had high risk of bias and two had unclear risk of bias. The PFA used in all these trials was fluoride varnish (FV). In meta-analyses, no significant difference was observed between participants receiving FV + RFT and RFT alone of d(m/e)fs increment (mean difference (MD) - 0.17, 95% confidence interval (CI) - 0.60 to 0.26, P = 0.43, I2 = 38%; 6 trials, 5,034 participants, moderate certainty evidence), incidence of caries (risk ratio (RR) 0.91, 95% CI 0.80 to 1.05, P = 0.21, I2 = 41%; 4 trials, 4,487 participants, moderate certainty evidence) or changes in prevalence of caries (RR 0.89, 95% CI 0.78 to 1.01, P = 0.07, I2 = 0%, 4 trials, 4,189 participants, low certainty evidence). CONCLUSIONS: Low to moderate certainty evidence suggests that FV does not have significant additional caries-preventive benefit for children (under 8 years old) when provided as an adjunct to daily tooth brushing with RFT (≥ 1,000 ppm). There is insufficient evidence regarding the additional benefit of other PFA interventions. CLINICAL RELEVANCE: The decision to apply FV to children needs to be made in light of their actual usage of RFT. TRIAL REGISTRATION: PROSPERO (CRD42020165270).

Is it necessary for children to receive professional fluoride in addition to regular fluoride toothpaste? Protocol for a systematic review.

INTRODUCTION: Regular toothbrushing with fluoride toothpaste is a fundamental intervention for caries prevention. Professional fluoride application (PFA) is widely considered a beneficial supplement to the routine use of fluoride toothpaste. However, some recent studies have failed to demonstrate the preventive effect of PFA. In addition, an increasing number of studies have highlighted the potential adverse effects of fluoride. However, little information exists on the effectiveness of additional PFA. The objective of this review is to systematically analyse the efficacy of PFA in addition to regular fluoride toothpaste among children under the age of 16. METHOD AND ANALYSIS: We will search the PubMed, Embase, Google Scholar and Cochrane Central Register of Controlled Trials databases for randomised controlled trials without language or publication date restrictions. Additional studies will be identified by manually searching the reference lists of the included studies and relevant reviews. At least two authors will carry out the selection of studies independently and in duplicate. The Cochrane Risk of Bias tool will be used to assess the risk of bias of the included studies. The random effects model will be used for meta-analyses. The data synthesis will be conducted using Review Manager software (RevMan V.5.3). The Grading of Recommendation, Assessment, Development and Evaluation will be used to assess the quality of supporting evidence for each major comparison. ETHICS AND DISSEMINATION: There is no need for ethical approval. The results of this review will be disseminated through peer-reviewed publications and social networks.
