Knowledge and attitudes of Mexican dentists regarding COVID-19 / Conocimiento y actitudes de dentistas mexicanos sobre la COVID-19

Dentists have a high risk of contracting COVID-19, they needed to be aware of the major challenge that represents the dental practice and COVID-19. Accordingly, this study aimed: 1) to investigate the knowledge of dentists regarding COVID-19, 2) to investigate the attitudes of dentists concerning the use of personal protective equipment and, 3) to investigate the attitudes of dentists on stopping their dental practices in the framework of a contingency plan for the COVID-19 outbreak. An online cross-sectional survey was applied to dentists (n=822). Dentists in Mexico answered the survey, which was administered before the contingency plan for the COVID-19 outbreak. Results were analyzed with descriptive statistics and with a Chi-square test (P≤0.05). Of the respondents, 99% of dentists indicated knowing what COVID-19 is, knowing most, but not all, of its signs and symptoms and knowing its mode of transmission. The 89% of dentists indicated that they always used personal protective equipment. But they did not use always wear face masks, protective eyewear, face shields, disposable gowns, and caps. Dentists were aware of the risk of performing dental procedures during the COVID-19 outbreak. The 90% of dentists indicated that they would treat only patients requiring emergency treatment, and 10% indicated that they would not treat any patients. The dentists had limited knowledge about the COVID-19 disease. They did not use personal protective equipment consistently, and they indicated that they might continue working during the COVID-19 outbreak.

Durante la pandemia por COVID-19, los dentistas han tenido un alto riesgo de contraer COVID-19.

La publicación científica en estomatología: un desafío para los investigadores / The scientific publication in stomatology: a challenge for researchers

La publicación de artículos científicos en odontología constituye la forma más apropiada para que un investigador dé a conocer los resultados de su trabajo; este reporte escrito representa la culminación del proceso de un estudio y resume los aspectos más relevantes del trabajo realizado –como son las características de los pacientes incluidos, el diseño empleado para dar respuesta a la pregunta planteada inicialmente, los materiales o procedimientos utilizados, los resultados y conclusiones emanados del estudio– en una forma coherente y estructurada. El propósito del presente artículo es dar a conocer algunos elementos de la definición de la publicación científica, la importancia de publicar en revistas de reconocido prestigio, el proceso de la publicación, la estructura de un artículo científico y los principales lineamientos para la publicación.

In dentistry, publishing scientific papers is the most effective way for researchers to disseminate the results of their work; these written reports represent the culmination of the research process and provide a summary of the most relevant aspects of the work carried out, such as the characteristics of the patients included, the design used to find the answer to the initial question, the materials or procedures used, and the results and conclusions of the study, all presented in a cohe­rent and structured manner.

Reparo de reabsorção radicular externa associada com queratocisto odontogênico; relato de caso / Healing of external root resorption associated with odontogenic keratocyst: case report

Introduction and Objective: A case of external root resorption associated to an Odontogenic Keratocyst is presented. Case Report and Conclusion: A review of the literature revealed that this cyst is not considered a common etiological factor for external root resorption. A X-ray examination showed root resorption in the teeth involved in an odontogenic keratocyst. Root canal treatment with calcium hydroxide mixed with propylenglicol was performed. The paste was applied at definite intervals during a 10 month period. X-rays were taken at each interval. At final X-rays examination there were no signs of root resorption and the filling was completed.

Introdução e Objetivo: O presente trabalho apresenta um caso de reabsorção externa associada a um Queratocisto Odontogênico. Relato do caso e Conclusão: A revisão da literatura pertinente revelou que tal cisto não é comumente associado à reabsorção externa da raiz. Exames radiográficos apresentaram reabsorção externa da raiz nos dentes envolvidos com a lesão cística.O tratamento endodôntico instituído utilizou hidróxido de cálcio associado ao propilenoglicol aplicado como medicação intra-canal em intervalos definidos durante 10 meses. Ao final do referido período o exame radiográfico demonstrou o reparo da reabsorção.
