    In 2020, the COVID-19 pandemic forced all university teaching to be taught online, including the teaching of human anatomy. The objective of this work was to evaluate the students' perception regarding digital resources and active strategies used in the online version of the human anatomy subject. The sample consisted of 77 first-year dentistry students who were studying anatomy. For data collection, a self-application questionnaire and three focus groups with semi-structured questions were used. Quantitative data were analyzed with descriptive statistics and qualitative data using grounded theory. The qualitative analysis determined 6 relevant categories expressed by the students: possibility of working collaboratively, feedback spaces, type of information, use of the material, perception of the academic and the time factor. Regarding the quantitative analysis, the manual of Applied Anatomy for Dentistry Students was the best evaluated digital resource (p<0.005), which was statistically significant. It was followed by the Visible Body 3D atlas as the second best evaluated digital resource (p < 0.005). While the analysis of clinical cases and the making of drawings were the best evaluated active strategies, they were statistically significant (p<0.005). The most recommended digital resource by the students, was the manual (30.4 %) followed by the Visible Body 3D atlas (28.5 %). The most recommended active strategy was group labeling of manual models (37.5 %). Students positively perceive the virtualization of the subject, highlighting the role of the teacher through feedback and peer interaction. © 2022, Universidad de la Frontera. All rights reserved.

    Perception of the Virtualization of the Subject of Normal Human Anatomy and Embriology in a Pandemic
    (Universidad de la Frontera, 2023-06) Rodríguez Luengo, Macarena; Águila Camacho, José; Pallauta Torres, Luis; Pérez Cárdenas, Nury; Luengo Mai, Diego; Niklander Ebensperger, Sven
    As a result of the pandemic and the restrictions regarding in person attendance, different learning methodologies had to be explored and implemented to virtualize the contents in the Anatomy subject. The objective of this study was to evaluate the perception of teachers and students regarding the methodologies used in the virtualization of this subject. An observational-descriptive study with a quantitative approach was carried out. The study population was a convenience sample made up of 57 students and 4 teachers of the Normal Human Anatomy and Embryology subject of the Dentistry degree, Universidad Andrés Bello, Viña del Mar campus during 2021. These participants answered a validated questionnaire that included closed questions with a 5-level Likert scale, considering learning dimensions, motivation and performance, and qualifying questions to find out the perception of the strategies and resources used. Students positively perceive all digital resources, highlighting the Normal Human Anatomy Manual, with learning being the best evaluated dimension. The best perceived active strategy in terms of the 3 dimensions corresponds to the case method. In contrast, the inverted classes were perceived negatively in all dimensions. In relation to teachers, the best perceived digital resource was videos and capsules, highlighting the motivation dimension. The best evaluated active strategies were the case method and inverted classes. Despite having a positive perception regarding virtualization, there is no agreement between the best evaluated active strategies and digital resources among teachers and students. © 2023, Universidad de la Frontera.

    Rendimiento masticatorio en pacientes portadores de prótesis removible parcial
    (Universidad Andrés Bello, 2010) Luengo Mai, Diego; Moyano de Sánchez, Gisela; Facultad de Odontología
    Objetivo: Determinar el rendimiento masticatorio en pacientes desdentados parciales sin y con el uso de prótesis removible, y establecer que otras variables determinan dichos valores. Material y método: Se seleccionaron 51 pacientes cuyas prótesis fueron instaladas y controladas en la UNAB Viña del Mar entre los años 2007 y 2009. Se le pidió a cada paciente que masticara a través de 20 golpes masticatorios una tableta de silicona de condensación Optosil®, tanto con y sin el uso de la aparatología prótesica. Los trozos obtenidos fueron expectorados en un recipiente de plástico para luego ser colados a través del método de tamizado múltiple. Lo anterior permitió la separación de las partículas según su tamaño (fracción gruesa, mediana y fina), y finalmente a través del pesaje de estas últimas y a la utilización del índice porcentual de Edlund y Lamm (1980) se obtuvo el porcentaje de RM sin y con prótesis respectivamente. El análisis estadístico fue realizado a través de los tests de Kruskal-Wallis y el test de Wilcoxon. Resultados: El uso de prótesis removible parcial aumenta en un 9% el RM en comparación a cuando no se utiliza; el RM tiende a ser mayor en hombres, es mayor en pacientes portadores de PRP metálica, es mayor con el aumento del número de pares oclusales, y con la presencia del par 1.6-4.6. Conclusión: El uso de prótesis removible aumenta significativamente el RM en pacientes desdentados parciales, además de existir otras variables que determinan dichos porcentajes.
