Professional use of social media platforms by independent dental hygienists in the Netherlands: A quantitative study.

AIM: This study examines the prevalence of the professional use of social media platforms by independent DHs in the Netherlands and assesses the associated personal and demographic factors. METHODS: In this exploratory, observational, cross-sectional study, independent DHs who were members of the Dutch Dental Hygienist Association (Nederlandse Vereniging voor Mondhygiënisten: NVM) were included. Data were collected from the DH practices' websites. Statistics included frequency distributions, percentages, chi-square tests for the relationship between the parameters, and multiple logistic regression for the associations between social media use and the personal and demographic factors. RESULTS: A total of 830 independent DHs from 670 different practices were included in the study. Of these DHs, 34.4% had a link to a social media platform on their website. DHs with practices in the west or south of the Netherlands were more likely to use Facebook (p = 0.035 and p = 0.002, respectively) than those in the east or north. The likelihood of DHs with 4 years of training using Facebook was 1.910 greater than those with 2 years of training (p = 0.002). Furthermore, DHs who graduated in Utrecht were more likely to use Instagram (p < 0.001). CONCLUSION: Over a third of the independent DHs in the Netherlands used social media for professional purposes. DHs who trained in Utrecht for 4 years and who had a practice in the west or south of the Netherlands were more likely to use social media for professional purposes.

Four-year outcomes of restored posterior tooth surfaces-a massive data analysis.

OBJECTIVES: There is only sparse knowledge concerning the outcomes of treatments with posterior permanent restorations in general practice settings. This study aimed at evaluating outcomes based on a large dataset by using a novel approach on a tooth surface basis. MATERIALS AND METHODS: The study based on routine data from a major German national health insurance company. Respective treatment fee codes allowed for tracking the clinical courses on a tooth surface level. The study intervention was defined as the placement of a restoration on an interproximal or occlusal posterior tooth surface regardless of its actual extension and material on which no information was available. All surfaces restored between January 1st, 2010 and December 31st, 2013 were included. Kaplan-Meier survival analyses were conducted to estimate four-year survival. The primary outcome was a restorative re-intervention on the same tooth surface. Separate analyses were performed for the secondary outcomes "crowning" and "extraction". RESULTS: Over ten million interproximal surfaces and eight million occlusal surfaces in nine million posterior teeth had been restored. At 4 years, the cumulative survival rates concerning the primary outcome "re-intervention" for mesial surfaces (81.4%; CI 81.3-81.5%) and distal surfaces (81.2%; CI 81.1-81.2%) differed significantly from those for occlusal surfaces (77.0%; CI 76.9-77.0%). Restored surfaces in premolars showed significantly higher survival rates compared to molars. Four-year survival rates for the secondary outcome "crowning" were 91.9% (CI 91.8-91.9%) for mesial surfaces, 92.1% (CI 92.1-92.2%) for distal surfaces and 93.3% (CI 93.2-93.3%) for occlusal surfaces. The respective rates for the secondary outcome "extraction" were 94.5% (CI 94.5-94.5%) for mesial surfaces, 94.8% (CI 94.7-94.8%) for distal surfaces and 95.4% (CI 95.4-95.5%) for occlusal surfaces. CONCLUSIONS: Re-interventions after restorative treatment play a significant role in general practice settings. Surface-related survival rates of restorations reveal a need for improvement. CLINICAL RELEVANCE: This study allows the estimation of the probability of re-interventions after restoring posterior tooth surfaces. It is based on several million cases from general practises under the terms and conditions of a national health insurance system.

Re-interventions after restoring teeth-Mining an insurance database.

OBJECTIVES: The aim of this study was to examine re-interventions after restorative treatment. METHODS: The data was collected from the digital database of a major German national health insurance company. Only permanent teeth were observed. Placing a permanent restoration other than a crown regardless of involved surfaces and material was the study intervention. The data did not allow for a differentiation between fillings and inlays that were estimated only a very small portion of the restorations. Success was defined as not undergoing any restorative re-intervention with fillings or inlays on the same tooth (primary outcome) and assessed with Kaplan-Meier survival analyses over four years. An additional analysis was conducted rating "crowning" and "extraction" of respective teeth as target events. Differences were tested with the Log-Rank-test. A multivariate Cox regression analyses was carried out. RESULTS: A total of 17,024,344 restorations placed in 4,825,408 anterior teeth and 9,973,177 posterior teeth could be traced. Focussing on the primary outcome re-intervention, the cumulative four-year success rate was 69.9% for one surface restorations, 74.8% for two surface restorations, 66.6% for three surface restorations and 61.0% for four surface and more extended restorations. These differences were significant (p<0.0001). Focussing on all three target events re-intervention, crowning and extraction, the cumulative four-year success rate was 66.1% for one surface restorations, 67.5% for two surface restorations, 63.0% for three surface restorations and 55.8% for four surface and more extended restorations. The number of restoration surfaces as well as the tooth position remained significant in the multivariate Cox regression. CONCLUSIONS: The sustainability of restorative dental treatment under the terms and conditions of the German national health insurance system shows room for improvement. From a public health perspective, special focus should be laid on primary and secondary prevention to minimize the restorative treatment need. CLINICAL SIGNIFICANCE STATEMENT: This study shows that re-interventions are observed regularly after restorative treatment. Therefore, preventive and restorative strategies should be revisited and optimised.

Brazilian young dental practitioners' use and acceptance of digital radiographic examinations.

PURPOSE: The aim of this study was to investigate the use and acceptance of digital radiographic examinations by Brazilian dental practitioners in daily practice and to evaluate the advances that have occurred over the past 5 years. MATERIALS AND METHODS: Dental practitioners enrolled in extension courses at the Piracicaba Dental School, University of Campinas, Brazil, responded to a self-administered questionnaire in the years 2011 and 2015. They were asked about sociodemographic factors and their knowledge and use of digital radiographic examinations. Descriptive analysis was performed, as well as the chi-square and Fisher exact tests, with a significance level of 5% (α=0.05). RESULTS: A total of 181 participants responded to the questionnaire in the years 2011 and 2015. Most of the respondents worked in private practice, had graduated within the last 5 years, and were between 20 and 30 years old. In 2011, 55.6% of respondents reported having ever used digital radiographic examinations, while in 2015 this number increased significantly to 85.4% (p<.0001), out of which 71.4% preferred it to conventional images. Moreover, 21.4% of respondents reported having used digital radiographic examinations for more than 3 years. A significant increase in use of intraoral digital radiography (p=0.0316) was observed in 2015. In both years, image quality and high cost were indicated, respectively, as the main advantage and disadvantage of digital radiographic examinations. CONCLUSION: This study showed that digital radiology has become more common in Brazil over the past 5 years. Most of the Brazilian dental practitioners evaluated in 2015 used digital radiographic examinations.

COVID-19 in dental practice ­ an overview of challenges and preventive measures / COVID-19 na prática odontológica ­ uma revisão sobre os desafios e medidas preventivas

COVID-19 was identified to be caused by a new coronavirus named as SARS-CoV-2. Since the outbreak of this disease, World Health Organization (WHO) declared a global public health emergency. SARS-CoV-2 has a high estimate rate of human-tohuman transmission mainly through inhalation/ingestion/direct mucous contact with respiratory droplets. Considering this high transmission capacity, several countries have already registered cases of infection by health professionals. Even though dentists are not directly involved in the diagnosis and therapy of COVID-19 they represent undoubtedly a risk group due to high exposure and their work environment is a contagion factor for patients and staff. In this manner, the objective of this article is to approach important aspects of COVID-19 concerning dental care and provides an overview of its challenges on dental practice. For this, we used these following keywords in our research: COVID-19; dental general practice; prevention and control; infectious disease transmission; infectious disease transmission, patient to professional. Taking into account the global concern with patient care in midst of this pandemic, we address valid concerns regarding the potential means of contamination in the dental office and highlight practices and guidelines adopted in different countries to minimize risks in dental care in this global public health crisis, thus, reinforcing the challenges of dentistry in this context, highlighting the importance of rigorous preventive measures. However, there is still a lack of standardization of dental care protocols and consequently, reduce the risk of contagion.

COVID-19 foi identificada como sendo causada por um novo coronavírus denominado SARS-CoV-2. Desde o surgimento da doença, a Organização Mundial da Saúde (OMS) declarou uma emergência global de saúde pública. O SARS-CoV-2 tem uma alta taxa estimada de transmissão de pessoa para pessoa, principalmente por inalação/ingestão/contato direto da mucosa com gotículas respiratórias. Considerando essa alta capacidade de transmissão, vários países já registraram casos de infecção por profissionais de saúde. Mesmo que os dentistas não estejam diretamente envolvidos no diagnóstico e terapia do COVID-19, eles representam, sem dúvida, um grupo de risco devido à alta exposição e seu ambiente de trabalho é um fator de contágio para pacientes e equipe. Dessa forma, o objetivo deste artigo é abordar aspectos importantes do COVID-19 no que diz respeito à assistência odontológica e apresentar um panorama de seus desafios na prática odontológica. Para isso, utilizamos as seguintes palavras-chave em nossa pesquisa: COVID-19; clínica odontológica geral; prevenção e controle; transmissão de doenças infecciosas; transmissão de doenças infecciosas do paciente para o profissional. Levando em consideração a preocupação global com o atendimento ao paciente em meio a esta pandemia, foram abordadas preocupações válidas sobre os meios potenciais de contaminação no consultório odontológico e destacadas as práticas e diretrizes adotadas em diferentes países para minimizar os riscos na assistência odontológica nesta crise global de saúde pública, reforçando assim os desafios da odontologia neste contexto, evidenciando a importância de medidas preventivas rigorosas. Porém, ainda falta padronização dos protocolos de atendimento odontológico e, consequentemente, redução do risco de contágio.

Three-year outcomes of root canal treatment: Mining an insurance database.

OBJECTIVES: There is doubt whether success rates of root canal treatments reported from clinical trials are achievable outside of standardized study populations. The aim of this study was to analyse the outcome of a large number of root canal treatments conducted in general practice. METHODS: The data was collected from the digital database of a major German national health insurance company. All teeth with complete treatment data were included. Only patients who had been insurance members for the whole 3-year period from 2010 to 2012 were eligible. Kaplan-Meier survival analyses were conducted based on completed root canal treatments. Target events were re-interventions as (1) retreatment of the root canal treatment, (2) apical root resection (apicoectomy) and (3) extraction. The influences of vitality status and root numbers on survival were tested with the log-rank test. RESULTS: A total of 556,067 root canal treatments were included. The cumulative overall survival rate for all target events combined was 84.3% for 3 years. The survival rate for nonvital teeth (82.6%) was significantly lower than for vital teeth (85.6%; p<0.001). The survival rate for single rooted teeth (83.4%) was significantly lower than for multi-rooted teeth (85.5%; p<0.001). The most frequent target event was extraction followed by apical root resection and retreatment. CONCLUSIONS: Based on these 3-year outcomes, root canal treatment is considered a reliable treatment in practice routine under the conditions of the German national health insurance system. CLINICAL SIGNIFICANCE: Root canal treatment can be considered as a reliable treatment option suitable to salvage most of the affected teeth. This statement applies to treatments that in the vast majority of cases were delivered by general practitioners under the terms and conditions of a nationwide health insurance system.

Clinical usefulness of teleradiology in general dental practice.

PURPOSE: This study was performed to investigate the clinical usefulness of teleradiology in general dental practice. MATERIALS AND METHODS: Two hundred and seventy five cases were submitted for inquiry to the case presentation board of the website of The Korean Academy of Oral and Maxillofacial Radiology for a 5 year periods. The diagnosis results of those cases were analyzed according to the disease classification, the correlation with the patient's chief complaint, the necessity of additional examinations or treatments, the image modalities, and the number of dentists inquiring. RESULTS: Differential diagnoses of normal anatomic structures were the most frequently submitted cases, covering 15.6% of all cases. Among 275 cases, 164 cases required no additional treatments or examinations. Panoramic radiographs were the most frequently submitted images, accounting for 248 inquiries. The 275 cases were submitted by 96 dentists. Fifty-two dentists wrote one inquiry, and 44 inquired 2 or more times. The average inquiry number of the latter group was 5.0 cases. CONCLUSION: A teleradiology system in general dental practice could be helpful in the differential diagnosis of common lesions and reduce unnecessary costs.

The Current Status of Dental Education and the Dental Profession in Chile

Objective: To describe the current situation of the dental profession in Chile, including training and workforce issues. Material and Methods: Data were collected from different national institutions, which included information regarding number of current registered dentists, university of graduation, geographical distribution, professional position, additional specialty certifications obtained, the number and characteristics of dental surgeons who work in the public and private sectors, the traditional character of the university, the accreditation status of the undergraduate dental programs and the general population number. Results: Currently there are 32 schools of Dentistry in Chile, of which 21 have their quality certified. There are 19,100 Chilean dentists and 1,727 foreign dentists registered. The number of graduates from private universities has increased significantly. Currently, 2,164 dentists work for MINSAL. Less than a third hold a specialty certification. Forty-five percent of the dental specialists obtained their certification from universities. The current professional ratio is 104 dentists per 100,000 habitants. Conclusion: The number of dentists in Chile has increased progressively during the last years, mainly associated with the opening of new dental schools. Only 28% of the Chilean dental schools have certified their quality for the total duration of the undergraduate program. Regarding the workforce, there is a public/private and geographical inequities in dentists' distribution.

Insights into the state of radiation protection among a subpopulation of Indian dental practitioners.

PURPOSE: Radiographs is an integral part of patient management in dentistry, despite their detrimental effects. As the literature pertaining to radiation protection among Indian dental practitioners is sparse, exploring such protection is needed. MATERIALS AND METHODS: All private dental practitioners in Mangalore, India were included in the study. A structured, pre-tested, self-administered questionnaire was employed to assess the knowledge, attitudes, practices, previous training, perceptions towards the need to spread awareness, and willingness to gain and implement knowledge about radiation hazards and protection. Information regarding each respondent's age, gender, education, and type and duration of practice was collected. RESULTS: Overall, 87 out of 120 practitioners participated in the study. The mean knowledge, attitude, and practice scores were 9.54±2.54, 59.39±7.01, and 5.80±3.19, respectively. Overall, 25.3% of the respondents had undergone training in radiation protection, 98.9% perceived a need to spread awareness, and 94.3% were willing to improve their knowledge. Previous training showed a significant correlation with age, sex, and duration of practice; attitude was significantly correlated with education and type of practice; and knowledge scores showed a significant correlation with type of practice. CONCLUSION: Although the knowledge and practices of respondents were poor, they had a positive attitude and were willing to improve their knowledge. Age, sex, and duration of practice were associated with previous training; education and type of practice with attitude scores; and type of practice with knowledge scores. The findings of this study suggest a policy is needed to ensure the adherence of dental practitioners to radiation protection guidelines.

Health Information Technology (HIT): A Hit or Miss in Private Dental Practice in Chennai, Tamil Nadu, India ­ A Cross Sectional Survey

Objective: To assess the knowledge, perception and use of Health Information Technology (HIT) among private dental practitioners in Chennai, Tamil Nadu, India. Material and Methods: The sample population consisted of private dental practitioners in Chennai District of Tamil Nadu who were individually approached to participate in the cross-sectional survey. A structured, self-reported, close-ended questionnaire, which contained queries on the knowledge, usage and concerns about HIT in their practice, was designed. Descriptive statistics such as frequency distribution and percentages were analyzed using SPSS version 24. Results: Of the 483 dental clinics that were approached, 352 dental practitioners completed the questionnaire survey. A significant proportion of dental practitioners (65 percent) reported positive attitude towards use of HIT systems and believed that HIT systems could help make their work easier and efficient. However, it is unfortunate to note that almost half (47 percent) the dental practitioners were not interested in implementing HIT systems in their practice due to various monetary concerns such as installation and maintenance costs. Conclusion: The widespread adoption of HIT provides system connectivity and information exchange among providers of the same organisation, providers at different organisations and, ultimately, providers practising regionally and nationally.

Consentimiento informado: aspectos éticos y legislación en la odontología / Informed consent: ethical issues and legislation in dentistry

Los avances científicos y su aplicación técnica en el ámbito de la odontología, ha motivado la reflexión bioética de la práctica en esta disciplina planteando las siguientes interrogantes: ¿cómo entender el papel del odontólogo?, ¿cómo se configura el universo bioético del odontólogo?, ¿cómo se posibilita el consentimiento válidamente informado? Para explorar la respuesta a estos cuestionamientos, se tiene como punto de partida la relación odontólogo-paciente, y se transita por aspectos de la bioética del odontólogo y las características del consentimiento informado en la práctica odontológica. La conclusión destaca la importancia de hacer del consentimiento informado el medio por el cual se recupera la dignidad de la persona mediante una relación ética y dialógica en tanto proceso mediante el cual se reconoce la alteridad del paciente durante la relación odontólogo- paciente además de coadyuvar a la educación en salud del paciente promoviendo su responsabilidad frente a la autonomía y sus derechos.

Scientific advances and their technical application in the field of Dentistry, have led to a bioethical reflection about practice in this discipline by asking questions like: how to understand the dentist´s role, how to set the dentist´s bioethical universe?, how is the valid informed consent made possible? To answer these questions, the patient-dentist relationship is taken as a starting point, and goes through the dentist´s bioethical aspects and informed consent characteristics in dental practice. The conclusion highlights the importance of the informed consent as a way to recover a person´s dignity by which the otherness of the patient is recognized as well as to contribute to the patient´s health education promoting responsibility towards autonomy and rights.
