Application of lecture-and-team-based learning in stomatology: in-class and online.

BACKGROUND: This study aimed to evaluate stomatological students' learning efficacy and their attitude towards Lecture-Team-Based Learning (LTBL) on topics regarding the design of removable partial dentures via in-class, online, and both in combination. METHODS: Students from seven distinct grades participated in the course in their fourth academic year (Years 2015, 2016, 2017, 2018, 2019, 2020, and 2021). Students of Years 2015-2019 attended in-class LTBL, students of Year 2020 attended online LTBL, and students of Year 2021 attended the combination mode. The scores of three examinations were compared, namely, individual readiness assessment test, team readiness assurance test, and individual application test. Visual Analog Scales (VAS) were used for students to self-assess their mastery of prosthodontics knowledge before and after the course. Anonymous questionnaires were delivered to evaluate their satisfaction with LTBL via a Likert scale. RESULTS: In each academic year, the three exam scores were significantly improved as the course progressed and VAS-post scores were significantly higher than VAS-pre scores. The three examination and VAS scores of students in Year 2020 were significantly lower than those in Years 2019 and 2021. Students were highly satisfied with the LTBL course based on the three parameters of knowledge acquisition, teamwork, and classroom atmosphere. CONCLUSION: Students were highly satisfied with the LTBL course and their learning performance was improved as the course progressed both in-class and online. Online LTBL could be adopted when students have to study online, while in-class LTBL could perform better when combined with video records of an online LTBL course.

Oral pathology and oral medicine in Latin American countries: current stage.

BACKGROUND: Oral Pathology (OP) and Oral Medicine (OM) are specialties in dentistry whose main objective is the diagnosis and treatment of oral and maxillofacial diseases, and aspects related to the academic training of professionals and fields of practice are distinct and heterogeneous around the world. This study aimed to evaluate professional training and areas of activity in OP and OM in Latin American countries. MATERIAL AND METHODS: A questionnaire was sent to 11 countries, with a professional in each country responsible for answering it. The questionnaire had 21 questions related to the process of professional training, areas of practice, the existence of scientific events in each country, and also collected demographic and population information. RESULTS: OP and OM are practiced in all the countries studied, but the specialty is not recognized in all of them. Brazil was the first to recognize both as a specialty. Postgraduate programs designed to train specialists are available in various countries. Two countries offer residency programs, 6 countries provide specialization courses, 6 offer master's programs, and 3 have doctoral programs. Brazil boasts the highest number of undergraduate courses (n=412), while Uruguay has the lowest (n=2). Professional societies representing the specialty exist in ten countries. Brazil has the highest number of OP and OM specialists (n=422 and 1,072), while Paraguay has the smallest number (n=1 and 3). CONCLUSIONS: Although both specialties are widely practiced around the globe, professional training, the number of dentists trained and the fields of professional practice are very different between the countries studied.

Analysis of the citation impact of Brazilian researchers in oral pathology and oral medicine over two decades.

BACKGROUND: Brazilian Oral Pathology (OP) and Oral Medicine (OM) have gained significant international recognition. However, no study has yet evaluated the impact of citations in scientific publications. Therefore, this study aimed to analyze the impact of citations from Brazilian researchers in OP and OM over the last two decades. MATERIAL AND METHODS: This was a cross-sectional study involving 50 researchers linked to postgraduate programs in OP/OM. Data collected from each professional's Lattes curriculum included gender, academic affiliation, the corporate category of the institution, and location. The number of papers published and citations received between 2004 to 2013 and 2014 to 2023 was also collected from the Web of Science database. RESULTS: Most researchers were male (56%) and from public institutions (90%), mainly in the Southeast region (60%). Over two decades, they collectively published 8,033 scientific articles, with significant growth (p<0.001) from to 2004-2013 to 2014-2023. While the average citations per researcher did not differ significantly between 2004-2013 and 2014-2023 (p=0.538), there was a notable 67.67% increase in citations in the last decade. CONCLUSIONS: Brazilian researchers in the areas of OP and OM have demonstrated a significant academic impact over the past two decades, with a marked increase in publications and citations over the last ten years. This highlights the contribution of Brazilians to the global scientific community in these areas.

Teleconsultations in oral medicine: dentist perception during the COVID-19 pandemic in Brazil.

BACKGROUND: The aim of this study was to describe the perception of dentists from the North macroregion of Minas Gerais, Brazil, users of telediagnosis in Oral Medicine, during the COVID-19 pandemic. MATERIAL AND METHODS: This is a cross-sectional and descriptive study. Data collection was carried out online, between May and October 2022. The information was transferred to the Statistical Package for the Social Sciences for Windows (SPPS)® version 24. RESULTS: The sample consisted of 255 dentists, predominantly female. Regarding perception, a significant percentage (47.8%) of respondents agreed that they would like to use telediagnosis frequently, more than half (60.6%) agreed that the technology is easy to use, only a small percentage (8.8%) needed technical support to use it and almost half (48.2%) mentioned the desire to continue using it after the pandemic. When asked if patients felt confident and comfortable when passing on information, more than half disagreed or remained neutral (58.4%), a similar result was found in relation to confidence in the application of the instrument by professionals. CONCLUSIONS: It is concluded that, during the pandemic, telediagnosis in Oral Medicine was an easy and adequate tool. However, professionals must be trained and prepared to be comfortable and ready for use.

With the increasing maturity and popularization of digital technology in oral medicine, its application has now expanded to various clinical subspecialties of oral medicine. Digitalization has become one of the important development directions of oral medicine. What is the current development status of digital technology in oral medicine? In what ways is digital technology applied across various clinical specialties of oral medicine? Dentists are particularly concerned about these issues in their clinical work and research. In this paper, all the digital technologies applied in oral medicine are organized and categorized from a technical perspective. In this paper, we focused on presenting three-dimensional data acquisition technology, dental computer-aided design technology, dental computer-aided processing technology, and oral surgery implementation technology. Their technical principles, technical characteristics, applications in oral medicine, a secondary discipline of medicine, and the development status of domestically-developed technology are described and reviewed in detail. The other technologies such as oral digital materials, oral virtual simulation teaching, and oral multi-source data management are briefly discussed. We intend to provide references for dentists to apply digital technology in clinical practice and research.

Pierre Fauchard's Contribution to Oral Medicine and Oral and Maxillofacial Pathology: An historical essay.

Pierre Fauchard, considered the father of dentistry, contributed to the development of different fields of dentistry that we know today. However, the contribution of this important individual to the fields of oral medicine and oral and maxillofacial pathology is unknown. This study aimed to identify Pierre Fauchard's contribution to these areas of dentistry. We focused on "Le Chirurgien Dentiste, or Traité des Dents" in both French and English, looking for information about the oral diseases diagnosed and treated by Fauchard. Information on patient history, disease description, treatment applied, and clinical follow-up was collected. A contemporary analysis of the diseases was performed, and the collected data were systematized, reported, and analyzed descriptively, according to the current literature on the addressed topics. Information on conditions such as scurvy, parulides, epulides, oral ulcers, dentoalveolar abscesses, dental alterations, and post-exodontia incidents were elucidated. Findings indicated that Pierre Fauchard described, diagnosed, and treated different soft and hard tissue diseases of great interest to the fields of oral medicine and oral and maxillofacial pathology.

[The analysis of medical personnel potential of stomatological service of the Subject of the Russian Federation considering its private sector].

The approaches to analysis of medical personnel of stomatological service continue to be based on principles formed in relation to state health care system that makes it difficult to objectively assess situation due to increasing proportion of specialists employed in its private sector. The study, targeted to comprehensive comparative analysis of stomatological medical personnel of state and private medical organizations in the Irkutsk Oblast, for the first time made it possible to assess provision of population of large region and its municipalities with stomatologists, considering specialists employed in private medical organizations, in dynamics and in context of separate specialties. The decrease in provision of population with stomatologists in state medical organizations by 12.3% in 2019-2023 against the background of its increase in private ones by 14.5% was revealed. In 2023, 50.5% of stomatologists were concentrated in private sector of stomatological service and 30.8% in state sector. Yet another 18.7% combined their work in medical organizations of both types. The stomatologists employed in private sector of stomatological service were mainly concentrated in metropolises, especially in regional center, where their provision exceeds average regional level by 2.6 times.

A personal journey through Oral medicine: The tale of hepatitis C virus and oral lichen planus.

Around 30 years ago, the hepatitis C virus (HCV) was identified and soon it was shown that this virus, further to the liver, could affect a variety of organ systems. This article summarizes how an association between HCV and a relatively common oral disorder, oral lichen planus (OLP), was revealed. Through key publications, many of them published in Journal of Oral Pathology and Medicine, it is shown the building of strong epidemiologic evidence supporting the association and how a plausible pathogenic link between HCV and OLP was discovered. As HCV infection is now potentially curable, modern direct antiviral agents can be used to effectively cure also OLP in HCV-infected patients.

Semi-flipped classroom-based learning interventions in a traditional curriculum of oral medicine: students' perceptions and teaching achievements.

BACKGROUND: In recent years, flipped classes have emerged and become popular in college medical education. However, due to the huge medical learning system and the limited pre-class study time of students, it is difficult to implement in all courses. And then we adopted the semi-flipped classes (SFCs) to evaluate its teaching effect. This study analysed three educational methods that can be used in oral medicine courses: online education, offline education, and semi-flipped classes. METHODS: We used two surveys to evaluate the three educational methods. In the first survey 46 teachers and 238 undergraduates shared their experience of the live-streaming and traditional offline courses offered in the different oral medicine curricula; we used anonymous questionnaires to evaluate their class experience. In the second survey 94 students shared their experience of the semi-flipped and traditional classrooms. Students who attended the SFCs in the experimental group learned about the oral mucosa disease by themselves using an online video course and then participated in offline interaction with teachers. The evaluation of the above educational methods was conducted using the anonymous questionnaires and final exam assessment. RESULTS: According to the first survey, teachers and students both agreed that the overall teaching experience and learning effectiveness in offline education are superior to those in online education. According to the second survey, students who participated in the SFCs performed better in the final exam than those who participated in the simple offline classes. Additionally, the survey showed that the new teaching method helped students gain more knowledge and positively influenced their clinical practice. CONCLUSIONS: Compared with the online and offline educational methods, the SFC showed better results in both the questionnaire and final exam assessment. Hence, the effectiveness of medical education can be improved by adopting a teaching mode that combines online and offline teaching methods. Scientific and logical SFCs designs, along with their effective implementation, would eventually make SFCs an important tool for medical education.

Integrative oral medicine: Dentistry's role in improving health outcomes.

OBJECTIVE: This article describes the importance of identifying inflammation-inducing conditions in the dental office that are prevalent in the population and have significant systemic health risks for the patient. The role of the dental biofilm will be presented, as will the clinical protocols for treating an unhealthy biofilm. Methods for testing and maintaining a healthy biofilm are also presented. CLINICAL CONSIDERATIONS: Periodontal disease, dental caries, and periapical infections are inflammation-inducing diseases that can be identified in the dental office. Additionally, sleep apnea has been linked to chronic systemic inflammation. Dentists can identify risk factors and provide treatments that lower the risk of serious systemic outcomes, such as atherosclerosis, cardiac arrest, and stroke. CONCLUSIONS: A thorough dental examination, including a comprehensive periodontal evaluation, can provide important information that can be used to improve or maintain a patient's systemic health. Treatments provided to improve oral health have been shown to improve systemic indicators of cardiovascular health. This is the basis of integrative oral medicine, a collaboration between the medical and dental providers, which can offer patients the best opportunity for improved health outcomes. CLINICAL SIGNIFICANCE: Periodontal disease, caries, periapical infections, and sleep apnea all have negative systemic health consequences for the patient (DiMatteo, Inside Dent, 2017, 13, 30; Nakano, Oral Microbiol Immunol, 2009, 24, 64; El Ouarti, BMC Oral Health, 2021, 21, 124; Lamberg, Steve). Periodontal disease, caries, and root end infections influence the health of the oral biofilm. If the biofilm becomes pathogenic the host inflammatory response can be stimulated, resulting in a cascade of inflammatory processes that damage the supporting structures of the teeth and harm the patient's overall health. A thorough dental exam that includes a comprehensive periodontal evaluation will identify patients with active inflammation or oral conditions that contribute to chronic inflammation. Dentists can integrate this information into treatment strategies that reduce the inflammatory burden and assist in better overall health outcomes.

Paediatric dentistry trainee views on training relating to the medically compromised child and oral medicine elements of specialty training curricula.

INTRODUCTION: Paediatric dentists care for children who are medically compromised and with an orofacial disease; therefore, trainees need appropriate training in these areas. The prevalence of congenital and chronic diseases in children is increasing, and future specialists need an understanding of human health and disease and oral medicine. This study aimed to determine if current teaching and assessments were fulfilling these requirements. MATERIALS AND METHODS: A survey distributed to the UK and Ireland specialty trainees asked their opinions on whether knowledge gained prior to entering training, and teaching and learning during training equipped them for future management of medically compromised children and those with oral medicine diagnoses. RESULTS: The response rate was 51% (26 trainees). Most were aware of curriculum elements for medically compromised children and oral medicine. The majority felt that knowledge and experience gained as undergraduates and early graduates was insufficient and recognised the need for these topics in speciality training. For medically compromised children, this learning was considered a good use of time by 96% of trainees, and 88% felt that this topic should be given more attention. For oral medicine, this learning was considered a good use of time by 96% of trainees, and 69% felt that this topic should have more attention. CONCLUSION: Paediatric dentistry specialty trainees recognise that knowledge and experience of managing patients considered medically compromised and those with oral medicine conditions are an important part of training and need greater emphasis, especially in light of changing demographics with congenital and acquired chronic disease, and children with oral medicine disorders.

Superficial mucoceles in cancer patients: a retrospective series from a Stomatology unit.

BACKGROUND: The aim of this study is to relate all the superficial mucoceles found in a cancer center, described the association with oncological conditions, and discuss its etiology and pathology that we found in the past few years. MATERIAL AND METHODS: Sixteen cases of superficial mucocele were retrieved from the patients' records of the Stomatology Department of the A. C. Camargo Cancer Center, São Paulo, Brazil, and demographic and clinical data were collected from electronic medical records. RESULTS: There were 16 patients, 8 patients were men and 8 women, with ages varying from 26 to 70 years old. Superficial mucoceles were observed in patients submitted to head and neck radiotherapy (n=6), graft versus host disease (n=4), one associated with oral mucositis related to allogenic bone marrow stem cells transplantation (n=1), systemic lupus (n=1), Sjögren's syndrome (n=1), oral lichenoid lesion associated with pembrolizumab (n=1) and no local or systemic inflammatory associated found (n=2). CONCLUSIONS: This study reports a series of superficial mucoceles from a single stomatology unit. Most patients had superficial mucoceles secondary to head and neck radiotherapy and graft versus host diseases. However, two patients (12.5%) had mucoceles related to systemic inflammatory conditions (Sjögren's Syndrome and Systemic Lupus).

[The stomatological care of schoolchildren in the Soviet Russia in 1920s: Succession of ideas].

The article considers historical interaction between the Soviet Russia and the Weimar Republic related to prevention of caries in children in 1920s and the role of P. G. Dauge in it. The methodology of German Professor A. Kantorovich with minor alterations was adopted to be applied in organization of dental care of schoolchildren in the RSFSR. In the Soviet Russia, the practical implementation of planned oral cavity sanation in children started on a national scale only in second half of the 1920s. It was caused by skeptical attitude of dentists to methodology of "planned sanation" in conditions of the Soviet Russia.
