The impact of digital healthcare and teledentistry on dentistry in the 21st Century: a survey of Hungarian dentists.

BACKGROUND: The era of digitalization has arrived in the field of dentistry. Teledentistry (TD), the use of digital solutions in dentistry, is already used in practice; however, only some possibilities are considered. During the COVID-19 pandemic, remote patient monitoring and patient communication had to be solved with TD, thus causing a rapid spread of new tools. In addition to digital workflows, patient communication, AI, and online forums are also available. METHODS: An online self-administered survey was developed for the study. The Hungarian Medical Chamber contacted potential respondents in a newsletter or e-mail. The Evasys survey system was used. The weighting procedure was executed for gender, age group, and type of settlement. A digital dental index variable was created and built with a linear regression model as a dependent variable. Explanatory variables are advantages, disadvantages, what would be necessary, experienced needs from the patients, and age. RESULTS: A total of 171 dentists completed the survey. The best-known digital technologies are online conferences (96.5%), E-prescriptions (94.6%), and digital impressions (86.0%). Unawareness is the highest in the field of artificial intelligence in dentistry (50.5%), store-forward solutions (43.5%), and real-time solutions (41.8%). The digital dental index is 14.24 (standard deviation (SD) = 5.5), with a high power of the model. CONCLUSION: Hungarian dentists need to be made aware of all the possibilities of TD. In addition to digital workflows, store-forward and real-time solutions can be beneficial to substitute face-to-face visits. TD can be used effectively to monitor oral cavity changes and develop dental confidence and proper oral care habits. Our survey suggests that it is necessary and inevitable to integrate TD into both graduate and postgraduate education, which may form the basis of primary health care in the next decade.

A phenomenological study on East and Southeast Asian dental educators: perceived importance, challenges, and strategies in teaching dental materials science.

BACKGROUND: Effective teaching of dental materials science is crucial for dental students to develop a comprehensive understanding of materials used in clinical practice. However, literature on educators' views on teaching this subject is still scarce. This qualitative study aimed to explore the lived experiences of dental educators in teaching dental materials science subjects, thereby addressing potential gaps and enhancing teaching practices. METHODS: Thirteen dental educators from East and Southeast Asian countries (Malaysia, China, Indonesia, Thailand, South Korea, and Japan) participated in the present study. The present study adopted a transcendental phenomenological approach. One-to-one semi-structured online interviews were conducted. Interviews were recorded and transcribed verbatim. Thematic analysis was employed to identify patterns in the educators' experiences. RESULTS: Three themes emerged from the present study. First, perceptions of the importance of dental materials science, highlighting its relevance in clinical practice, patient care, and lifelong learning. Second, the challenges faced in teaching dental materials science include limited instructional time, complex content, and insufficient resources. Third, specific strategies, such as applying interactive teaching methods, integrating clinical scenarios, and promoting critical thinking skills have been suggested to enhance teaching and learning. CONCLUSION: Understanding dental educators' experiences can improve dental materials science education, curriculum development, teaching methods, and faculty training programmes, ultimately enhancing the knowledge and skills of dental students in this field.

Modelo para la evaluación de la eficacia diagnóstica de la tomografía computarizada de haz cónico en odontología / A model of diagnostic efficacy for the evaluation of CBCT in dentistry

Introducción: Debido al riesgo que conlleva la exposición a radiación ionizante, se han establecido los principios de protección radiológica, con el propósito de regular las actividades que involucran su uso. Uno de estos principios es la justificación de los exámenes, es decir, la indicación del examen cuando exista la posibilidad de que éste entregue información en beneficio del paciente. Esto implica que dicho examen se evalúe en cuanto a su rendimiento, de manera que exista evidencia que indique su capacidad de entregar la información necesaria para la indicación específica del paciente. Revisión: Para evaluar el rendimiento de los exámenes imagenológicos, con el fin de orientar su uso como herramienta diagnóstica en las distintas indicaciones odontológicas, se ha usado el modelo de Eficacia Diagnóstica descrito por Fryback y Thornbury en 1991.En odontología, el uso de la tomografía computarizada de haz cónico (TCHC) ha aumentado debido a sus ventajas como herramienta diagnóstica. Aún así, son pocas las investigaciones en altos niveles del modelo de Eficacia Diagnóstica -más relacionados con características aplicables al paciente--y muchas las investigaciones en bajos niveles -más relacionado con calidad técnica y de exactitud diagnóstica-. Conclusiones: La evidencia del rendimiento de la TCHC en bajos niveles puede generar una idea equivoca sobre sus indicaciones, dando la impresión de que cuenta con respaldo científico suficiente que justifica su uso. Es necesaria investigación enfocada en el beneficio de los pacientes con el uso de TCHC para las distintas indicaciones en odontología. (AU)

Introduction: Due to the risk of exposure to ionizing radiation, principles of radiation protection have been established, with the aimto regulate activities that involve the use of ionizing radiation. The principle of justification means that the indication of the exam must be associated to the possibility of providing information for the benefit of the patient. The indication of an exam that results in a benefit for the patient entails the evaluation of the exam in terms of its performance. This evaluation should demonstrate the exam has ability to deliver the necessary information for the specific need of the patient. Review: The Diagnostic Efficacy model, described by Fryback and Thornbury in 1991, is used to evaluate the performance of imaging tests, in order to guide its use as a diagnostic tool in different dental indications. In dentistry, the use of TCHC has increased due to the advantages as a diagnostic tool. Still, there are few investigations at high levels of the Diagnostic Efficacy model - related to characteristics that involve the patient - and many investigations at low levels - more related to technical quality and diagnostic accuracy. Conclusions: Evidence of the performance of CBCT at low levels generates a misunderstanding about its use, giving the impression that CBCT has sufficient scientific support to justify its use. Currently, the evaluation of the performance of the TCHC has focused on evaluating the lowest levels of this model, the image quality and the diagnostic precision, although evidence at this level remains limited. Research focusing on the benefit of patients with the use of CBCT for the different indications in dentistry is needed. (AU)

Ultrasound protocol in odontogenic infections: a new proposal

Background: Point-of-care-ultrasound can be applied to preview a difficult airway, detect the presence of fluid collection, and soft-tissue edema, and guide the drainage location, although is rarely used. The purpose of this study is to validate a protocol for the assessment of these clinical features on patients with severe odontogenic infections.Material and methods: This was a single-group prospective cohort study (n=20) including patients with the diagnosis of deep-neck propagation of odontogenic infection. A transcervical linear high-frequency probe transducer (13-6 MHz) was used to scan the structures of the upper airway and the infectious collections. The drainage was guided by ultrasound and the patients were daily evaluated, according to the protocol. The data were extracted and the airway volume, midline deviation, and other important data such as length of hospital stay, dysphagia, voice alteration, raised floor of the mouth, dyspnea, and neck swelling were registered.Results: The ultrasound examination was correlated with multiple clinical findings, such as dyslalia (p=0,069), dysphagia (p=0,028), dyspnea (p=0,001), among others. This protocol has an advantage as it can be used at bedside evaluation, allowing the assessment of severe and unstable patients, and predicting the increase of the hospitalization time (p=0,019).Conclusions: This protocol is reliable for the assessment of the upper airway, even in an emergency, predicting not only the severity of the clinical features but aids in the determination of the length of the hospitalization time.

As Práticas Integrativas e Complementares (PICs) apresentam-se como métodos coadjuvantes, auxiliando na obtenção de sucesso em determinados tratamentos clínicos e/ou cirúrgicos, atuando na prevenção, auxiliando na cura e no equilíbrio psicossomático com a finalidade de reestabelecer concordância entre mente e corpo. O Conselho Federal de Odontologia (CFO) regulamentou práticas como acupuntura, hipnose, terapia floral e fitoterapia, entretanto, suas aplicabilidades dependem da emissão de uma habilitação e seu devido registro no Conselho (Resolução CFO 82/2008). Para a Odontologia, as PICs proporcionam novas ferramentas para exercer um atendimento integral do ser humano. Neste trabalho, propõe-se fazer uma revisão de literatura sobre as PICs e Odontologia. Esta revisão de literatura foi realizada por meio de busca de artigos na base de dados Scielo, PubMed e Scholar Google no período de 2000 a 2021. Foram encontrados artigos sobre as seguintes PICs atuando conjuntamente com a Odontologia: terapias florais, acupuntura, hipnodontia, ozonioterapia, laserterapia, fitoterapia, homeopatia e odontologia antroposófica. Essas práticas apresentam grande valia, pois promovem o bem-estar sem causar dano ao indivíduo, apresentando poucos ou nenhum efeito colateral possibilitando maior segurança aos pacientes, além de favorecer a relação entre paciente e cirurgião-dentista, otimizando o tempo de trabalho no consultório odontológico e reduzindo custos.

Integrative and Complementary Practices (PICs) are presented as supporting methods, helping to achieve success in certain clinical and/or surgical treatments, acting in prevention, assisting in healing and psychosomatic balance in order to reestablish agreement between mind and body. . The Federal Council of Dentistry (CFO) has regulated practices such as acupuncture, hypnosis, floral therapy and herbal medicine, however, their applicability depends on the issuance of a license and its proper registration with the Council (Resolution CFO 82/2008). For Dentistry, PICs provide new tools to provide comprehensive care to human beings. In this work, we propose to review the literature on PICs and Dentistry. This literature review was carried out by searching articles in the Scielo, PubMed and Scholar Google databases from 2000 to 2021. Articles were found on the following PICs working together with Dentistry: floral therapies, acupuncture, hypnodontics, ozone therapy , laser therapy, phytotherapy, homeopathy and anthroposophic dentistry. These practices are of great value, as they promote well-being without causing harm to the individual, presenting few or no side effects, allowing greater safety for patients, in addition to favoring the relationship between patient and dentist, optimizing working time in the dental office and reducing costs.

Inter-incisive index in Bulgarians and its application in dentistry / Indice interincisivo en búlgaros y su aplicación en odontología

SUMMARY: In recent years, aesthetic dentistry has become a major focus for the public. Facial attractiveness plays a key role on modern society and the creation of harmonious smile is an aim for every dentist. The objective of this study was to define certain values of the inter-incisive index in Bulgarians, the sexual dimorphism and bilateral asymmetry and to verify differences of this index between Bulgarians and other Balkan populations. The present study included 121 males and 111 females of Bulgarian origin aged 20- 40 years. Mesiodistal dimensions of maxillary central and lateral incisors were measured by Dentistry Sliding Vernier Caliper. We used the technique of direct anthropometry, modified by Prof. Y. Yordanov. We calculated the inter-incisive index as ratio of the mesiodistal dimension of maxillary lateral incisor to the mesiodistal dimension of the maxillary central incisor. The measurements were analyzed with SPSS 23. The level of statistical significance was set at P< 0.05. The inter-incisive index showed no statistically significant differences between left and right side of the dental arch in both sexes. We did not find statistically significant differences between males and females as well. On the other hand, we found statistically significant differences in MD values of incisors between Bulgarians and other Balkan nations. Inter-incisive index shows no sexual dimorphism and bilateral asymmetry in Bulgarians. This can be helpful in aesthetic dentistry, in prosthodontics and in orthodontic treatment planning.

RESUMEN: En los últimos años, la odontología estética se ha convertido en un foco importante para el público. El atractivo facial juega un papel clave en la sociedad moderna y la creación de una sonrisa armoniosa es importante para todos los dentistas. El objetivo de este estudio fue definir ciertos valores del índice interincisivo en búlgaros, el dimorfismo sexual y la asimetría bilateral y verificar diferencias de este índice entre búlgaros y otras poblaciones balcánicas. El presente estudio incluyó a 121 hombres y 111 mujeres de origen búlgaro entre 20 y 40 años de edad. Las dimensiones mesiodistales de los incisivos superiores centrales y laterales se midieron con un calibrador Vernier deslizante de odontología. Utilizamos la técnica de antropometría directa, modificada por el Prof. Y. Yordanov y se calculó el índice interincisivo como la relación entre la dimensión mesiodistal del incisivo lateral superior y la dimensión mesiodistal del incisivo central superior. Las medidas se analizaron con SPSS 23. El nivel de significancia estadística se fijó en P<0,05. El índice interincisivo no mostró diferencias estadísticamente significativas entre los lados izquierdo y derecho de la arcada dentaria en ambos sexos. Tampoco encontramos diferencias estadísticamente significativas entre hombres y mujeres. Por otro lado, encontramos diferencias estadísticamente significativas en los valores de DM de los incisivos entre búlgaros y otras naciones balcánicas. El índice interincisivo no muestra dimorfismo sexual ni asimetría bilateral en los búlgaros. Esto puede ser útil en odontología estética, en prostodoncia y en la planificación de tratamientos de ortodoncia.

A dental revolution: The association between occlusion and chewing behaviour.

Dentistry is confronted with the functional and aesthetic consequences that result from an increased prevalence of misaligned and discrepant dental occlusal relations in modern industrialised societies. Previous studies have indicated that a reduction in jaw size in response to softer and more heavily processed foods during and following the Industrial Revolution (1,700 CE to present) was an important factor in increased levels of poor dental occlusion. The functional demands placed on the masticatory system play a crucial role in jaw ontogenetic development; however, the way in which chewing behaviours changed in response to the consumption of softer foods during this period remains poorly understood. Here we show that eating more heavily processed food has radically transformed occlusal power stroke kinematics. Results of virtual 3D analysis of the dental macrowear patterns of molars in 104 individuals dating to the Industrial Revolution (1,700-1,900 CE), and 130 of their medieval and early post-medieval antecedents (1,100-1,700 CE) revealed changes in masticatory behaviour that occurred during the early stages of the transition towards eating more heavily processed foods. The industrial-era groups examined chewed with a reduced transverse component of jaw movement. These results show a diminished sequence of occlusal contacts indicating that a dental revolution has taken place in modern times, involving a dramatic shift in the way in which teeth occlude and wear during mastication. Molar macrowear suggests a close connection between progressive changes in chewing since the industrialization of food production and an increase in the prevalence of poor dental occlusion in modern societies.

Valoración de los estadios de maduración ósea a través de las vértebras cervicales / Assessment of skeletal maturation stages using cervical vertebrae

RESUMEN La Ortodoncia se preocupa por la corrección precoz de la maloclusión; esta especialidad prioriza la armonía de las bases óseas en relación con la discrepancia y el posicionamiento dentario, aspectos que pueden ser corregidos en cualquier época de la vida. Por estas razones, es de gran importancia conocer el pico de crecimiento. La tendencia actual en Ortodoncia, en la evaluación de la maduración ósea, es reducir el número de radiografías a las estrictamente necesarias, por lo que existen una serie de investigadores que han desarrollado índices de maduración esquelética con los perfiles de los cuerpos de las vértebras cervicales. Estas aparecen generalmente en las telerradiografías laterales de cráneo, y son utilizadas para el diagnóstico ortodóncico, lo cual favorece la eliminación de radiografías adicionales. Se recomienda utilizar el método de la evaluación de maduración ósea a través de las vértebras cervicales en los servicios cubanos de Ortodoncia.

ABSTRACT Orthodontics is concerned with the early correction of malocclusion; this speciality prioritizes the harmony of the bony bases in relation to the discrepancy and dental positioning, aspects that can be corrected at any time of life. For these reasons, it is of great importance to know the growth peak. The current trend in Orthodontics, in the evaluation of skeletal maturation, is to reduce the number of radiographs to those strictly necessary; that is why there are a number of researchers who have developed skeletal maturation indices with the profiles of the cervical vertebral bodies. These generally appear on lateral skull teleradiographs, and are used for orthodontic diagnosis, which favours the elimination of additional radiographs. It is recommended to use the method of skeletal maturation evaluation through the cervical vertebrae in Cuban orthodontic services.

The Teledentistry, Impact, Current Trends, and Application in Dentistry: A Global Study.

OBJECTIVE: The present study was aimed at assessing the impact of teledentistry, its application, and trends in uplifting dental practice and clinical care around the world. Material and Methods. The present observational study comprised of an electronic survey distributed among dental professionals around the globe. The validated survey form consisted of a total 26 questions with 5-point Likert scale response. The questionnaire used was divided into four domains: usefulness of teledentistry for patients, its usefulness in dental practice, its capacity to improve the existing practice, and the concerns attached to its use. The statistical analysis was performed using SPSS-25. ANOVA test was used to assess the effect of independent variables on dependent variables. A p value of ≤0.05 was taken as statistically significant. RESULTS: A total of 506 dental professionals participated in the study with the response rate of 89.39%. More than half of the participants (50-75%) endorsed that teledentistry is a useful tool for improving clinical practice as well as patient care. Two-thirds of the participants (69.96%) considered that teledentistry would reduce cost for the dental practices. On the other hand, about 50-70% of dental professionals expressed their concerns regarding the security of the data and consent of patients. The most preferred communication tool for teledentistry was reported to be videoconference followed by phone. The majority of participants recommended the use of teledentistry in the specialty of oral medicine, operative dentistry, and periodontics. There was a significant difference between the age, experience of dentists, and their qualifications with domains of teledentistry. CONCLUSIONS: The overall impact of dental professionals towards teledentistry was positive with adequate willingness to incorporate this modality in their clinical practice. However, the perceived concerns pertaining to teledentistry are significant impediments towards its integration within the oral health system. An in-depth study of its business model and cost-benefit needs of time, especially in the context of developing countries, in order to avail the optimum benefits of teledentistry.

Medical Clearance for Common Dental Procedures.

Medical consultations before dental procedures present opportunities to integrate cross-disciplinary preventive care and improve patient health. This article presents recommendations related to patients with certain medical conditions who are planning to undergo common dental procedures, such as cleanings, extractions, restorations, endodontic procedures, abscess drainage, and mucosal biopsies. Specifically, prophylactic antibiotics are not recommended for preventing prosthetic joint infections or infectious endocarditis except in certain circumstances. Anticoagulation and antiplatelet therapies typically should not be suspended for common dental treatments. Elective dental care should be avoided for six weeks after myocardial infarction or bare-metal stent placement or for six months after drug-eluting stent placement. It is important that any history of antiresorptive or antiangiogenic therapies be communicated to the dentist. Ascites is not an indication for initiating prophylactic antibiotics before dental treatment, and acetaminophen is the analgesic of choice for patients with liver dysfunction or cirrhosis who abstain from alcohol. Nephrotoxic medications should be avoided in patients with chronic kidney disease, and the consultation should include the patient's glomerular filtration rate. Although patients undergoing chemotherapy may receive routine dental care, it should be postponed when possible in those currently undergoing head and neck radiation therapy. A detailed history of head and neck radiation therapy should be provided to the dentist. Multimodal, nonnarcotic analgesia is recommended for managing acute dental pain.

In Vivo Study of Aerosol, Droplets and Splatter Reduction in Dentistry.

Oral health care workers (OHCW) are exposed to pathogenic microorganisms during dental aerosol-generating procedures. Technologies aimed at the reduction of aerosol, droplets and splatter are essential. This in vivo study assessed aerosol, droplet and splatter contamination in a simulated clinical scenario. The coolant of the high-speed air turbine was colored with red concentrate. The red aerosol, droplets and splatter contamination on the wrists of the OHCW and chests of the OHCW/volunteer protective gowns, were assessed and quantified in cm2. The efficacy of various evacuation strategies was assessed: low-volume saliva ejector (LV) alone, high-volume evacuator (HV) plus LV and an extra-oral dental aerosol suction device (DASD) plus LV. The Kruskal-Wallis rank-sum test for multiple independent samples with a post-hoc test was used. No significant difference between the LV alone compared to the HV plus LV was demonstrated (p = 0.372059). The DASD combined with LV resulted in a 62% reduction of contamination of the OHCW. The HV plus LV reduced contamination by 53% compared to LV alone (p = 0.019945). The DASD demonstrated a 50% reduction in the contamination of the OHCWs wrists and a 30% reduction in chest contamination compared to HV plus LV. The DASD in conjunction with LV was more effective in reducing aerosol, droplets and splatter than HV plus LV.

Teledentistry as a Supportive Tool for Dentists in Pakistan.

The current scenario of the COVID-19 pandemic has forced dentists to seek different options for delivering healthcare services other than the in-person direct examination in clinical practice. Teledentistry is one of the options for remote patient care and monitoring. Objective. The present survey was conducted to assess the knowledge and perception of the dentists in Pakistan regarding teledentistry as an emergent supportive tool. Materials and Methods. A self-administered, close-ended, and prevalidated survey questionnaire was used, comprising 21 questions, and distributed electronically via e-mail, WhatsApp, and Facebook Messenger to evaluate the knowledge and perception of dentists regarding teledentistry. The data collected was compiled in a systematic manner and analyzed in terms of frequency (yes/no). Results. Out of a total of 350 dentists, 325 responded to the questionnaire, and it was seen that 62.5% of them did not have knowledge about teledentistry prior to COVID-19. 65.8% of dentists considered the practice of teledentistry in nonpandemic situations in the future. Conclusion. In the present study, it was observed that most of the dental professionals had inadequate knowledge about teledentistry before COVID-19, but the awareness and perception regarding teledentistry were currently satisfactory among the dental professionals in Pakistan. This emerging trend gives a positive hope for the implementation of teledentistry in the healthcare setup of Pakistan in the near future, as it will prove to be beneficial for safe dental practice during times of pandemic and even after.

Artificial Intelligence Techniques: Analysis, Application, and Outcome in Dentistry-A Systematic Review.

OBJECTIVE: The objective of this systematic review was to investigate the quality and outcome of studies into artificial intelligence techniques, analysis, and effect in dentistry. MATERIALS AND METHODS: Using the MeSH keywords: artificial intelligence (AI), dentistry, AI in dentistry, neural networks and dentistry, machine learning, AI dental imaging, and AI treatment recommendations and dentistry. Two investigators performed an electronic search in 5 databases: PubMed/MEDLINE (National Library of Medicine), Scopus (Elsevier), ScienceDirect databases (Elsevier), Web of Science (Clarivate Analytics), and the Cochrane Collaboration (Wiley). The English language articles reporting on AI in different dental specialties were screened for eligibility. Thirty-two full-text articles were selected and systematically analyzed according to a predefined inclusion criterion. These articles were analyzed as per a specific research question, and the relevant data based on article general characteristics, study and control groups, assessment methods, outcomes, and quality assessment were extracted. RESULTS: The initial search identified 175 articles related to AI in dentistry based on the title and abstracts. The full text of 38 articles was assessed for eligibility to exclude studies not fulfilling the inclusion criteria. Six articles not related to AI in dentistry were excluded. Thirty-two articles were included in the systematic review. It was revealed that AI provides accurate patient management, dental diagnosis, prediction, and decision making. Artificial intelligence appeared as a reliable modality to enhance future implications in the various fields of dentistry, i.e., diagnostic dentistry, patient management, head and neck cancer, restorative dentistry, prosthetic dental sciences, orthodontics, radiology, and periodontics. CONCLUSION: The included studies describe that AI is a reliable tool to make dental care smooth, better, time-saving, and economical for practitioners. AI benefits them in fulfilling patient demand and expectations. The dentists can use AI to ensure quality treatment, better oral health care outcome, and achieve precision. AI can help to predict failures in clinical scenarios and depict reliable solutions. However, AI is increasing the scope of state-of-the-art models in dentistry but is still under development. Further studies are required to assess the clinical performance of AI techniques in dentistry.

Engineering of a Biomimetic Interface between a Native Dental Tissue and Restorative Composite and Its Study Using Synchrotron FTIR Microscopic Mapping.

The aim of this work is to develop a biomimetic interface between the natural tooth tissue and the restorative composite and to study it on the basis of synchrotron micro-FTIR mapping and multidimensional processing of the spectral data array. Using hierarchical cluster analysis of 3D FTIR data revealed marked improvements in the formation of the dentine/adhesive/dental hybrid interface using a biomimetic approach. The use of a biomimetic strategy (application of an amino acid-modified primer, alkaline calcium and a nano-c-HAp-modified adhesive) allowed the formation of a matrix that can be structurally integrated with natural dentine and dental composite. The biomimetic hybrid layer was characterised by homogeneous chemical composition and a higher degree of conversion of the adhesive during polymerisation, which should provide optimal integration of the dental composite with the dentine.

Teledentistry and COVID-19: Be Mindful of Bogus "Good" Ideas!

The current health crisis has led to the emergence of new practices, new tools, and an increased use of digital health. Unfortunately, these are too often developed in a way that defies all logic or which has nothing to do with public health. Oral health professionals have been particularly affected during this crisis, and the use of digital health, and especially teledentistry, has been considered in many countries. However, the development of teledentistry is not free of bogus "good" ideas. It is time that teledentistry be adequately considered, while ensuring the quality of the medical procedure and with the aim of reducing inequalities in terms of access to oral healthcare and public health problems.

Current State of Serious Games in Dentistry: A Scoping Review.

Objective: Over the past decade, serious games (SGs) have played a growing role in medical education and health promotion; however, little is known about their use in the field of oral health. This study provides a comprehensive synthesis about SGs developed for training oral health professionals or for health promotion in oral health. Material and Methods: A systematic search was conducted. The following electronic databases were reviewed: MEDLINE (1966 to September 2019), Embase (1980 to September 2019), and Cochrane Central Register of Controlled Trials (CENTRAL), LILACS and Scopus from inception to September 2019. Two reviewers independently screened and assessed the study's quality and extracted data. The Sardi and collaborators' tool was used to assess the quality of the evidence presented. Results: A total of 19 studies (25 articles) were selected. Games were divided into two categories: for specific educational purposes and for oral health promotion. Most studies involved oral health professions' students (n = 9) or school/preschool children (n = 9). Two studies included preschool children and parents. Interactive SGs were as effective as traditional noninteractive methods in improving oral health outcomes. Nonetheless, participants' feedback reflected a higher level of satisfaction in learning through games. The quality of the studies was limited due to the lack of a proper technical description of the games and the absence of discussion of the limitations and challenges of the games. Conclusion: The use of SGs in oral health is limited, and little valid empirical evidence is available to confirm their effectiveness. Further studies are required for using more rigorous designs, evaluation, and follow-ups.

Aerosol generation and control in the dental operatory: An in vitro spectrometric study of typical clinical setups.

Dental turbines and scalers, used every day in dental operatories, feature built-in water spray that generates considerable amounts of water aerosol. The problem is that it is not exactly known how much. Since the outbreak of COVID-19, several aerosol safety recommendations have been issued-based on little empirical evidence, as almost no data are available on the exact aerosol concentrations generated during dental treatment. Similarly, little is known about the differences in the efficacy of different commercially available aerosol control systems to reduce in-treatment aerosol load. In this in vitro study, we used spectrometry to explore these questions. The time-dependent effect of conventional airing on aerosol concentrations was also studied. Everyday patient treatment situations were modeled. The test setups were defined by the applied instrument and its spray direction (high-speed turbine with direct/indirect airspray or ultrasonic scaler with indirect airspray) and the applied aerosol control system (the conventional high-volume evacuator or a lately introduced aerosol exhaustor). Two parameters were analyzed: total number concentration in the entire measurement range of the spectrometer and total number concentration within the 60 to 384 nm range. The results suggest that instrument type and spray direction significantly influence the resulting aerosol concentrations. Aerosol generation by the ultrasonic scaler is easily controlled. As for the high-speed turbine, the efficiency of control might depend on how exactly the instrument is used during a treatment. The results suggest that scenarios where the airspray is frequently directed toward the air of the operatory are the most difficult to control. The tested control systems did not differ in their efficiency, but the study could not provide conclusive results in this respect. With conventional airing through windows with a standard fan, a safety airing period of at least 15 minutes between treatments is recommended.

Are propolis extracts potential pharmacological agents in human oral health? - A scoping review and technology prospecting.

ETHNOPHARMACOLOGICAL RELEVANCE: The antimicrobial potential of propolis - a honey bee product - was correlated with its traditional use as a natural medicine, mainly known for antimicrobial and antioxidant properties. Moreover, research on natural products in dentistry has increased in recent years in the search for products with greater therapeutic activity, lower toxicity, better biocompatibility, and more affordable cost to the population. OBJECTIVE: Considering that the beneficial effect of propolis is acknowledged for several oral conditions, this study aimed to synthesize the research and technological forecasts of existing evidence on the use of propolis extract as a potential antimicrobial agent in dentistry. METHODS: Studies were identified through an investigation in the PubMed, Web of Science, Scopus, and Scielo electronic databases. Additionally, the following patent databases were screened: Google Patents, WIPO, INPI, Espacenet, and Questel Orbit. The data were tabulated and analyzed using Microsoft Office Excel 2013 and Questel Orbit. RESULTS: A total of 174 scientific articles and 276 patents fulfilled all the criteria and were included in the investigation. The highest number of patents (n = 144) was produced by China. Additionally, the most prevalent studies were performed on an experimental basis (72%), followed by clinical studies (n = 27) and review articles (n = 21). The effect of using propolis has been extensively observed in oral care products, periodontics, pathology, and cariology, among other dental specialties. CONCLUSION: It was possible to identify the current scientific and technological scenario of the application of propolis in dentistry, with the number of patents increasing in recent years. However, all studies related to the use of propolis in dentistry have shown a potentially safe antimicrobial agent in an extensive field of application.
