COVID-19 pandemic accelerated virtual transformation in dental education: a multicenter review of remote teaching and teledentistry / Transformação virtual acelerada pela pandemia de COVID-19 na educação odontológica: uma revisão multicêntrica do ensino à distância e da teleodontologia

ABSTRACT Although prior to the pandemic there was some resistance to the virtualization of dental education, the COVID-19 pandemic is providing us a unique opportunity to overcome several barriers that previously blocked the adoption of remote teaching and teledentistry. Thanks to the extended availability of telecommunications, digital technologies, and platforms, remote education and teledentistry appear to be the preferred choice to maintain dental education and patient care active under this pandemic, without contamination risks. In this paper, we review valid remote education strategies and possible alternatives useful in virtual transformation in dental education. Furthermore, the role of teledentistry and its advantages and challenges are also revised. Under the current pandemic context, as dental educators, we are called to be creative and flexible. Every dental school should adapt and use remote education as much as possible until clinical attention can be readopted. The evidence presented in this review supports our position that under this pandemic, remote education and telemedicine/teledentistry may be "the virtual convenient solution", to adapt and improve the hitherto classic way of teaching dentistry through tele-education.

RESUMO Embora antes da pandemia houvesse alguma resistência à virtualização da educação odontológica, a pandemia COVID-19 está nos fornecendo uma oportunidade única de superar várias barreiras que anteriormente bloqueavam a adoção do ensino à distância e teledontologia. Graças à ampla disponibilidade de telecomunicações, tecnologias digitais e plataformas, a educação à distância e a teledontologia parecem ser a escolha preferida para manter a educação odontológica e o atendimento ativo aos pacientes durante a pandemia, sem riscos de contaminação. Neste artigo, revisamos estratégias válidas de educação a distância e possíveis alternativas úteis na transformação virtual na educação odontológica. Além disso, o papel do teleodontologia e suas vantagens, assim como também os desafios. No atual contexto pandêmico, como educadores odontológicos, somos chamados a ser criativos e flexíveis. Cada escola de odontologia deve se adaptar e usar a educação à distância, tanto quanto possível, até que a atenção clínica possa ser readotada. As evidências apresentadas nesta revisão corroboram nossa posição de que, sob esta pandemia, a educação a distância e a telemedicina / teleodontologia podem ser "a solução virtual conveniente", para adaptar e aprimorar a forma até então clássica de ensino de odontologia, agora por meio da teleducação.

Strategies and operational procedures in oral radiology to mitigate potential SARS-CoV-2 transmission / Estrategias y procedimientos operacionales en Radiología Oral para mitigar transmisión de SARS-CoV-2

SUMMARY Coronavirus disease (COVID-19) is highly transmissible through respiratory droplets, saliva, and aerosol particles. Infection can lead to severe acute respiratory syndrome and trigger multi-organ failure and death. Most clinical dental procedures involve contact with saliva or the generation of aerosols with saliva and blood. These airborne particles increase the risk of transmission by COVID-19 between dentists and patients. Thus, dentistry must adopt procedures to reduce transmission during dental procedures. Although these strategies may not be directly applicable to all institutions due to cultural, social, geographical, and economic differences, the underlying principles and implemented strategies remain relevant and can be adopted or modified by the institutions dealing with the current COVID-19 outbreak. The purpose of this article is to discuss one of the principal sources of COVID-19 transmission: saliva, the biofluid most frequently handled in a radiology environment. The authors also recommend strategies and operational procedures to decrease the spread of COVID-19 in a radiological routine.

RESUMEN La enfermedad por coronavirus (COVID-19) se transmite fácilmente a través de gotitas respiratorias, saliva y partículas de aerosol. La infección puede desencadenar un síndrome respiratorio agudo severo, insuficiencia multiorgánica y, en algunos casos, la muerte. Los procedimientos clínicos dentales determinan el contacto con saliva o la generación de aerosoles con saliva y sangre, lo que implica un alto riesgo de transmisión por COVID-19 entre odontólogos y pacientes. Por ello, la práctica odontologica debe adoptar medidas para detener la propagación durante los procedimientos dentales. En este artículo se revisan las estrategias para mitigar el riesgo de transmisión de COVID-19. Si bien estas estrategias pueden no ser directamente aplicables a todas las instituciones debido a diferencias culturales, sociales, geográficas y económicas inherentes, los principios subyacentes y las estrategias implementadas siguen siendo relevantes y pueden ser adoptados o modificados por las instituciones que se ocupan del brote actual de COVID-19. El propósito de este artículo es discutir una de las principales fuentes de transmisión de COVID-19: la saliva, el biofluido que se maneja con mayor frecuencia en un entorno radiológico. Los autores también recomiendan estrategias y procedimientos operativos para disminuir la propagación de COVID-19 en una rutina radiológica.

Tendencias de la mortalidad por cáncer oral y el efecto de las políticas públicas de prevención en América Latina / Trends in oral cancer mortality and the effect of preventive policies across Latin America

OBJETIVO: Describir las tendencias de la mortalidad por cáncer oral entre 2000 y 2017 por sexos en 20 países de América Latina, e identificar los efectos de las políticas implementadas para controlar de los factores de riesgo. MATERIALES Y MÉTODOS: Se realizó un estudio ecólogico que evaluó la relación entre las tasas estandarizadas por edad de mortalidad por cáncer oral según el sexo, la prevalencia de tabaquismo y consumo de alcohol y la implementación de las políticas públicas de control. RESULTADOS: Los hombres de Cuba y Brasil muestran las más altas tasas de mortalidad en la región. Los descensos más importantes se presentan en los hombres de Brasil y en las mujeres de Panamá. Son pocas las tendencias al aumento, aunque éstas se evidencian especialmente entre las mujeres. La implementación de las medidas de control de factores de riesgo, en cuanto a tabaco, alcohol, infecciones virales, programas de detección temprana y tratamiento, muestra avances desiguales entre los países. Se observó una mayor relación entre la mortalidad por cáncer oral con el consumo de tabaco en los contextos de menor implementación de las políticas, y el consumo de alcohol en los escenarios de mayor avance. CONCLUSIÓN: La mortalidad por cáncer oral afecta especialmente a los hombres de la región, lo que se puede asociar a la distribución de los factores etiológicos y avances desiguales de los países en la implementación de las medidas preventivas. Se requiere profundizar en investigación subnacional de seguimiento, y fortalecer la prevención y tratamiento con estrategias validas para cada contexto.

OBJECTIVE: To describe the trends in oral cancer mortality between 2000 and 2017 by sex in 20 countries in Latin America, and identify the effects of the policies that were implemented to control associated risk factors. MATERIALS AND METHODS: An ecological study was conducted to evaluate the relationship between age-standardized rates of oral cancer mortality by sex, the prevalence of smoking and alcohol consumption, and the implementation of public control policies. RESULTS: Men in Cuba and Brazil show the highest mortality rates in the region. The most important decreases occurred among Brazilian men and Panamanian women. There are only a few cases of increasing trends, although these are especially evident among women. The implementation of risk factor control measures, in terms of tobacco, alcohol, viral infections, early detection programs and treatment, have progressed unevenly in different countries. A strong relationship was observed between oral cancer mortality and tobacco consumption in countries with limited policy implementation; and with alcohol consumption in countries with advanced implementation. CONCLUSION: Oral cancer mortality especially affects men in the region, which can be associated with the distribution of etiological factors and unequal advances in countries in the implementation of preventive measures. It is necessary to further develop subnational follow-up research and strengthen prevention and treatment measures with valid strategies, adapted for each context.
