ABSTRACT
BACKGROUND: COVID-19 has had a major impact on dental activity, with implications on dental education. The aim of this study was to assess the knowledge about it and the pandemic impact on Spanish dental students. MATERIAL AND METHODS: An observational and cross-sectional study with a 17-items questionnaire was conducted. It was divided into three sections, sociodemographic data, self-perception and knowledge about the COVID-19 protective measures and repercussions on dental students. This survey was carried out in May 2020, and the response rate was 46.16%. The statistical analysis was performed by the Pearson chi-square test and Fisher's exact test. RESULTS: A total of 235 students responded to the questionnaire, with an average age of 22.3 years. Attendance at COVID-19 training courses, knowledge about the Personal Protective Equipment (PPE) management and the incubation period had the worst results, compared to the knowledge about hand washing, wearing gloves and masks and symptomatology who got higher percentages. 31.1% of participants reported presenting symptomatology related to SARS-CoV-2, although only 8.2% were diagnosed and 46.6% suffered quarantine. 62.5% were afraid to catch the disease. CONCLUSIONS: The results of this study show that there are deficiencies in the knowledge of important aspects of COVID-19 in dental students, which implies a commitment of the university in its training, as well as the realization of diagnostic controls for the disease. Key words:Dental students, SARS-CoV-2, COVID-19, survey, knowledge.
ABSTRACT
Objetivos.- Los objetivos de nuestro estudio fueron la valoración de las características epidemiológicas de los dientes supernumerarios y análisis de las complicaciones clínicas-eruptivas asociadas a los mismos.Diseño del estudio.- Estudio observacional longitudinal en el que participó una muestra de 2000 pacientes, a los que se les realizó una ficha donde se registraron los datos de filiación, presencia de dientes supernumerarios, localización, accidentes mecánicos y presencia de patología asociada.Resultados.- La presencia de dientes supernumerarios supuso el 1,05% de la población estudiada, con una media de edad de 20,2 años y mayor frecuencia de aparición en hombres. La localización más habitual fue la maxilar en un 79,2%, principalmente en la zona retromolar y a nivel de la premaxila. La presencia de accidentes mecánicos fue la complicaciónmás frecuente en un 54%, siendo el desplazamiento de dientes adyacentes el más habitual, junto a la presencia de quistes foliculares.Conclusiones.- Los dientes supernumerarios presentaron una frecuencia de aparición del 1,05%, localizándose más frecuentemente a nivel distomolar superior y los accidentes mecánicos fueron la complicación más habitual
Objectives.- An evaluation is made of the epidemiological characteristics of supernumerary teeth, with an analysis of the associated clinical-eruptive complications.Study design.- A longitudinal observational study was made of 2000 patients, with the documentation of demographic data, the presence of supernumerary teeth, their location, mechanical accidents and the presence of associated pathology.Results.- The presence of supernumerary teeth was recorded in 1.05% of the study subjects (mean age 20.2 years), with a greater frequency in males. The most frequent location was in the upper maxilla (79.2%), fundamentally in the retromolar zone and at premaxillary level. The presence of mechanical accidents was the most frequent complication (54%) the displacement of adjacent teeth being the most common finding along with the presence of follicular cysts.Conclusions.- The prevalence of supernumerary teeth in our series was 1.05%, the most frequent location being at upper distomolar level. Mechanical accidents were the most frequent complication

The most frequent location was in the upper maxilla (79.2%), fundamentally in the retromolar zone and at premaxillary level. The presence of mechanical accidents was the most frequent complication (54%)--the displacement of adjacent teeth being the most common finding--along with the presence of follicular cysts. CONCLUSIONS: The prevalence of supernumerary teeth in our series was 1.05%, the most frequent location being at upper distomolar level. Mechanical accidents were the most frequent complication.

En la actualidad existe una gran controversia con respecto a la colocación y remoción de restauraciones de amalgama, en la paciente embarazada, debido a la posible toxicidad que pueda producir a nivel fetal o materno. El objetivo de este estudio es realizar una revisión acerca del paso del mercurio a través de la barrera placentaria, y su acumulación en los tejidos, así como, sus efectos negativos. Existen estudios que demuestran el paso de todas las formas de mercurio a través de la barrera placentaria en diferentes cantidades, pero no hay evidencias científicas que demuestren relaciones entre la aparición de patologías y la existencia de obturaciones de amalgama. Por consiguiente es necesaria la realización de más investigaciones que permitan llegar a resultados concluyentes (AU)
Currently there is a great controversy about the placement and there motion of amalgam fillings in pregnant pacients, because of the possibiliy of toxicity to fetal or maternal level. The study objective is to revise all the information about the mercury pass across the placental barrier, its accumulation on tissues and the negative effects. There are studies that show that all mercury forms can pass across the placental barrier but there is not scientific evidence of relationship between amalgam fillings and pathology. Its necessary more studies to arrive at conclusive results (AU)
