Uncovering a pseudoscience: an analysis of 'biological dentistry' Instagram posts.

OBJECTIVE: This infodemiology study aimed to analyze characteristics of English-language Instagram posts on 'Biological Dentistry'. MATERIALS AND METHODS: Using CrowdTangle, we analyzed 500 'Biological Dentistry' posts published on Instagram from May 2017 to May 2022. Two researchers assessed each post for facticity, motivation, author's profile, sentiment, and interaction metrics. Statistical analysis was employed to compare interaction metrics between dichotomized categories of posts' characteristics and determine predictors of misinformation and user engagement. RESULTS: Over half of the posts (58.4%) were from health-related authors, and a considerable number contained misinformation (68.2%) or were financially motivated (52%). Sentiment was mostly negative or neutral (59.8%). Misinformation was associated with financial motivation (OR = 2.12) and health-related authors (OR = 5.56), while non-health-related authors' posts associated with higher engagement (OR = 1.98). Reliable content, non-health-related authorship, and positive sentiment were associated with increased user interaction. CONCLUSION: Misinformation about 'Biological Dentistry' on Instagram is mainly spread by financially incentivized health-related authors. Yet, non-health-related authors' posts resonate more with audiences, highlighting a nuanced relationship between content facticity, authorship, and engagement.

The phenomenological approach in dentistry - a narrative review.

PURPOSE: Phenomenology is a branch of philosophy that focuses on human lived experience. Illness including dental diseases can affect this living experience. Within the dental literature, there is very little reported on the use of phenomenology compared to other healthcare sciences. Hence, the aim was to review the literature and provide an overview of various applications of phenomenology in dental research. METHODS: This study was a narrative review using literature in the last 10 years identified by web-based search on PubMed and Scopus using keywords. A total of 33 articles that were closely related to the field and application in dentistry were included. The methodology, main results, and future research recommendations, if applicable, were extracted and reviewed. RESULTS: The authors in this study had identified several areas such as orofacial pain and pain control research, dental anxiety, dental education, oral healthcare perceptions and access, living with dental diseases and dental treatment experience in which the phenomenological method was used to gain an in-depth understanding of the topic. CONCLUSIONS: There are several advantages of using the phenomenological research method, such as the small sample size needed, the diverse and unique perspective that can be obtained and the ability to improve current understanding, especially from the first-person perspective.

Automotive Technology Revolutionized Restorative Dentistry Discovery of Alpha-diketone/Amine Catalyst: Part II -Reflections on Photopolymerization from Conception to Development of Composite Resin and Activator Light.

A full account of the preceded early research tribulation that led to the development of the first visible light activated composite resin and the first visible light activator source is documented. The events took place over four years since early 1974 when a raw industrial composite resin that was radiolucent, stiff paste, universal optically opaque white color, polymerized by exposure to a prototype visible light for 120 seconds was given to developed. Four years later, the developed restorative composite resin ended up as a radiopaque, optically translucent, universal color with an additional three shades that possessed the biologic, esthetic, mechanical and physical characteristics with proven efficacy be used for esthetic zone. This conservative account of early development of a technology that must count as one of a small number of inventions during the seventies, over the years has revolutionized restorative dental practice. We were privileged and very lucky to be associated with developmental stages, stumbling blocks, and final success of the first LC Composite resin that ignited the thought process worldwide and laid the foundation for modern esthetic restoratives practiced today.

Automotive Technology Revolutionized Restorative Dentistry Discovery of Alpha-diketone/Amine Catalyst: Part I.

A full account of early research that led to the discovery of the Alpha-diketone and Amine systems by two Imperial Chemical Industries (ICI) researchers. UK Chemists in the mid-sixties marked the beginning in the early development of a composite resin cured with visible light spectrum into a solid mass. Its incorporation into the newly developed Urethane based resin, led to conceiving the idea of developing the first light-activated restorative composite resin, which formed the prototype of modern composite restorative materials. How all that came about, and the ideas that were conceived and pursued in the development of these systems are discussed in detail.

Development and validation of a nomogram for predicting depressive symptoms in dentistry patients: A cross-sectional study.

Depressive symptoms are frequently occur among dentistry patients, many of whom struggle with dental anxiety and poor oral conditions. Identifying the factors that influence these symptoms can enable dentists to recognize and address mental health concerns more effectively. This study aimed to investigate the factors associated with depressive symptoms in dentistry patients and develop a clinical tool, a nomogram, to assist dentists in predicting these symptoms. Methods: After exclusion of ineligible participants, a total of 1355 patients from the dentistry department were included. The patients were randomly assigned to training and validation sets at a 2:1 ratio. The LASSO regression method was initially employed to select highly influrtial features. This was followed by the application of a multi-factor logistic regression to determine independent factors and construct a nomogram. And it was evaluated by 4 methods and 2 indicators. The nomograms were formulated based on questionnaire data collected from dentistry patients. Nomogram2 incorporated factors such as medical burden, personality traits (extraversion, conscientiousness, and emotional stability), life purpose, and life satisfaction. In the training set, Nomogram2 exhibited a Concordance index (C-index) of 0.805 and an Area Under the Receiver Operating Characteristic Curve (AUC) of 0.805 (95% CI: 0.775-0.835). In the validation set, Nomogram2 demonstrated an Area Under the Receiver Operating Characteristic Curve (AUC) of 0.810 (0.768-0.851) and a Concordance index (C-index) of 0.810. Similarly, Nomogram1 achieved an Area Under the Receiver Operating Characteristic Curve (AUC) of 0.816 (0.788-0.845) and a Concordance index (C-index) of 0.816 in the training set, and an Area Under the Receiver Operating Characteristic Curve (AUC) of 0.824 (95% CI: 0.784-0.864) and a Concordance index (C-index) of 0.824 in the validation set. Net Reclassification Improvement (NRI) and Integrated Discrimination Improvement (IDI) indicated that Nomogram1, which included oral-related factors (oral health and dental anxiety), outperformed Nomogram2. We developed a nomogram to predict depressive symptoms in dentistry patients. Importantly, this nomogram can serve as a valuable psychometric tool for dentists, facilitating the assessment of their patients' mental health and enabling more tailored treatment plans.

Could retaining the dental recall interval save NHS dentistry?

The World Health Assembly in May 2021 was a watershed moment in oral health, with the landmark resolution that designated oral diseases as non-communicable diseases (NCDs). This was strongly supported by a host of other NCDs in recognition of the common risk factor principle and acknowledgement of the fact that oral diseases do not occur in isolation from other NCDs, but are commonly associated with cardiovascular disease, diabetes/obesity, respiratory diseases, metabolic syndrome, a range of other inflammatory disorders and cancers. Regular monitoring and early detection would potentially intercept these NCDs and this could form a central plank of a revamped holistic 'health'- as opposed to 'disease'-oriented health care system.Consultation with patients and dentists reveals strong support for maintaining regular recall intervals, which maintains trust and optimises motivation and compliance. In-person visits could be minimised by using technology, such as remote consultations and longitudinal monitoring systems, making it adaptable to different health care settings and equitable, affordable, cost-effective and sustainable.A new paradigm with dentists as oral health professionals, and the mainstreaming of oral health and population-level prevention, means the future of health care can be guided by integration and workforce modification producing a surveillance-based, early interceptive, preventive model of care.

What is occlusion? Part 2.

Some dentists choose to ignore the subject of occlusion, while others propose a set of doctrinal rules. It is of little wonder therefore that it can become a source of confusion and even controversy. This series of two papers aims, firstly, to answer the very simple question of 'what is occlusion?'. It will put occlusion into the context of the articulatory system because that is the bio-mechanical environment where the majority of dentists do their work. The concept of jaw relation will also be discussed but within the context of this locomotive system. Ideal occlusion will be described but only after answering the question: for whom or what might an occlusion be considered ideal? Although, in the book of which this is the first chapter, he presents what has worked for him during many years as a general dental practitioner, university lecturer and specialist in restorative dentistry, he has tried not to be didactic because he feels that, in a profession, there are no right answers, only the right questions.

Bernard Geoffrey Norman Smith (1938-2016).

Bernard Smith was one of the most significant specialists in restorative dentistry of his generation. He was an inspiring undergraduate and postgraduate teacher, a noted international lecturer and a house-builder. Bernard was president of the British Society for Restorative Dentistry and first chairman of the Association of Consultants and Specialists in Restorative Dentistry.

Chapare virus infection and current perspectives on dentistry.

OBJECTIVES: This narrative review addresses relevant points about Chapare virus (CHAV) entry in oral cells, CHAV transmission, and preventive strategies in dental clinical settings. It is critical in dentistry due to the frequent presence of gingival hemorrhage occurred in CHAV-infected patients. MATERIALS AND METHODS: Studies related to CHAV were searched in MEDLINE/PubMed, Scopus, EMBASE, and Web-of-Science databases without language restriction or year of publication. RESULTS: Recently, the PAHO/WHO and CDC indicate a presence of human-to-human transmission of CHAV associated with direct contact with saliva, blood, or urine, and also through droplets or aerosols created in healthcare procedures. CHAV was detected in human oropharyngeal saliva and gingival bleeding was confirmed in all cases of CHAV hemorrhagic fever, including evidence of nosocomial CHAV transmission in healthcare workers. We revisited the human transferrin receptor 1 (TfR1) expression in oral, nasal, and salivary glands tissues, as well as, we firstly identified the critical residues in the pre-glycoprotein (GP) complex of CHAV that interacts with human TfR1 using cutting-edge in silico bioinformatics platforms associated with molecular dynamic analysis. CONCLUSIONS: In this multidisciplinary view, we also point out critical elements to provide perspectives on the preventive strategies for dentists and frontline healthcare workers against CHAV, and in the implementation of salivary diagnostic platforms for virus detection, which can be critical to an urgent plan to prevent human-to-human transmission based on current evidence. CLINICAL RELEVANCE: The preventive strategies in dental clinical settings are pivotal due to the aerosol-generating procedures in dentistry with infected patients or suspected cases of CHAV infection.

Ceramic biomaterials in dentistry: chemical structure and biosafety - a review and a bibliometric visual mapping on Scopus database.

OBJECTIVE: A biomaterial is any non-pharmaceutical substance or a mixture of synthetic or natural substances used independently or as part of a system for any amount of time with the aim of mending, supporting the growth, or replacing tissues, organs, or functions of the body. It is a non-renewable material that interacts with biological systems. The purpose of this study was to assess the advances in ceramic biomaterials and perform a bibliometric mapping of the literature on the subject. MATERIALS AND METHODS: The Scopus database was used for manuscript screening (Elsevier, Amsterdam, The Netherlands). The effect of the scientific production has been assessed using scientometric citational metrics. RESULTS: A total of 2,554 pieces of literature, including 2,234 papers, 170 conference proceedings, 109 reviews, 35 book chapters, 3 editorial letters, and 3 short surveys, were retrieved. Based on the research conducted, it is noted that ceramic materials are high-performing by being porous or glassy and can, therefore, serve as fillers, covering materials, and scaffolds in medicine and biotechnology. They are frequently employed not only in orthopedic and maxillofacial surgery but also in dentistry for dental prostheses. CONCLUSIONS: Materials monitoring methods enable us to track the three-dimensional evolution of ceramics' volume, as well as flaws or micro-cracks.

[Specification for the clinical application of Nd:YAG laser in dentistry].

The utilization of Nd: YAG laser in oral clinical practice has witnessed a notable surge, garnering recognition for its therapeutic efficacy through extensive domestic and foreign research. However, the establishment of specification for the clinical application of Nd: YAG laser in dentistry remains pending. The Oral Health Branch Association of China Association of Gerontology and Geriatrics has convened distinguished medical experts from diverse disciplines across China to engage in deliberations and develop a specification encompassing the application standard of Nd: YAG laser in various dental subspecialties. The purpose of this specification is to facilitate the standardization of clinical applications of Nd: YAG laser, effectively harnessing the advantages of laser technology in oral diagnosis and treatment, and ultimately enhancing the therapeutic outcomes of diseases.

Charting the Future of Oral Health: A Bibliometric Exploration of Quality-of-Life Research in Dentistry.

In recent decades, the focus of health research has shifted to the impact of disease or impairment on how people proceed, behave, and experience quality of life. People's lives are affected by oral diseases in various ways. Oral health-related quality of life (OHRQoL) is inextricably linked to general health and well-being, and it has far-reaching consequences for clinical practice and dentistry research. Particularly in Indonesia, increasing attention to OHRQoL is related to several concerning oral conditions, such as the extremely high number of cases of tooth decay and inflammation of dental supportive tissue that inexplicably lowers the population's OHRQoL. To date, there has yet to be a bibliometric study of OHRQoL research in Indonesia. We intend to map the existing scientific literature on OHRQoL research in Indonesia during the last five years and investigate its research gaps. Scopus and the Sinta Database (a national database through Google Scholar) were used to retrieve Indonesian OHRQoL research publications from 2018 to 2023. Bibliographic data were analyzed using SPSS Statistics 25.0 and VOS Viewer 1.6.19. The data demonstrate that the number of OHRQoL-related publications in Indonesia and the number of local writers have increased over time. More of these publications were published in prestigious national journals than foreign ones. The study found that local researchers tended to conduct OHRQoL research on children and older populations, raising the issue of tooth decay or tooth loss. Exploring other subjects, such as dental anxiety, patient satisfaction, chewing performance, aesthetics, and appearance, and other populations (people with oral cancer and other systemic conditions) could broaden the environment of OHRQoL research in Indonesia.
