Estrés y desempeño académico en estudiantes de OdontologíaStress and academic achievement in students of dentistry Resumen El propósito de este estudio fue evaluar el estrés académico y su repercusión con el desempeño acadé-mico de los estudiantes de odontología. Metodología: se trabajó con una muestra probabilística de 186 estudiantes de odontología que cursaron el semestre académico 2014-1, distribuidos de forma estratificada por año de estudios: primero(n=37); segundo(n=29); tercero(n=44); cuarto(n=36) y quinto(n=40) y seleccionados de manera aleatoria simple. La medición de la variable estrés académico se realizó a través del cuestionario Inventario SISCO validado, que evalúa: estresores académicos, manifestaciones del estrés y las estrategias de afrontamiento y que obtuvo una consistencia interna de 0.768. La variable desempeño académico se midió a través de la nota promedio del estudiante al término del semestre 2014-1. Para el análisis estadístico se utilizó pruebas estadísticas bivariadas y multivariadas. Resultados y conclusiones: se encontró que el 100% de los estudiantes presentaron en algún momento situación de estrés con una intensidad promedio de 3.5. El rendimiento académico promedio fue de 13.21(basado en el sistema vigesimal 0-20). Los estudiantes de años de estudio superiores presentaron un mayor rendimiento académico, no evidenciándose diferencias estadísticamente significativas según sexo. En el análisis multivariado se halló que la habilidad asertiva es el factor determinante en el rendimiento académico de los estudiantes de odontología (Beta 0.167, p<0.05).Palabras clave: Estrés académico; desempeño académico; estudiantes; odontología. AbstractThe purpose of this study was to evaluate academic stress and its impact in the academic performance of students of dentistry. Methodology: we worked with a probabilistic sample of 186 dental students who completed the semester 2014-1, stratified by year of study: first (n = 37); second (n = 29); third (n = 44); fourth (n = 36) and fifth (n = 40) and single randomly selected. The measurement of academic stress variable was performed through the SISCO inventory validated questionnaire, which assesses: academic stressors, manifestations of stress and coping strategies and obtained an internal consistency of 0.768. The academic performance variable was measured by the average student at the end of the semester 2014-1. For statistical analysis, bivariate and multivariate statistical tests were used. Results and conclusions: it was found that 100% of the students presented sometime stressful situation with an average intensity of 3.5. The average academic performance was 13.21. Students in the senior years of study have a higher academic performance, demonstrating no statistically significant differences by sex. It was found in the multivariate analysis that assertive ability is the determining factor in academic performance of students of dentistry (Beta 0.167, p <0.05).Keywords: Academic stress; academic performance; students; dentistry.

This study aimed to determine the general labor well-being of Latin American dentists according to sociodemographic characteristics during the COVID-19 pandemic. A cross-sectional study was conducted in a final sample of 2214 participants from 11 countries. A validated online questionnaire on general work well-being was used (data collection period from 1 June to 10 July 2021), containing two dimensions: psychosocial well-being and collateral effects. The sociodemographic characteristics of the dentists and their perception of the economic impact of the pandemic were also recorded. A multivariate linear regression analysis was performed (hierarchical regression model) to evaluate the joint effect of the explanatory variables on labor well-being and the changes in the variance between each model. A score of psychosocial well-being of 233.6 + 40.2 and collateral effects of 45 + 20.1 was found. Psychosocial well-being was associated with sex, country of origin, academic training achieved, type of dental activity, and perceived impact during the pandemic (p < 0.05). Somatization was frequently manifested through back pain (88.2%) and muscular tensions (87.2%). Women, those who worked 41 or more hours and had between 1 to 15 years of professional experience presented a greater collateral effect (p < 0.001). The impact of the COVID-19 pandemic a year and a half after it began on the labor well-being of Latin American dentists was evidenced with important interactions with social characteristics.

Introduction: Non-carious lesions are an oral health pro-blem in adults, consequently it is necessary to create mechanisms for their diagnosis and prevention. Objective: To determine the frequency of erosion, abrasion and related factors in patients treated at a university dental clinic. Material and Methods: A cross-sectional study was conducted in a sample of 153 adults treated at a university clinic in Lima, Peru, in 2018. Personal aspects (age, sex, characteristics of saliva), dietary factors, health condition, oral habits, and tooth brushing were identified. The presence of abrasion was determined according to clinical criteria through direct observation. Erosion was identified using the Basic Erosive Wear index. Generalized linear models with Poisson distribution with robust variances were used. Results: The frequency of dental abrasion (70.6%) is higher than erosion (26.1%). The presence of erosion is associated with asthma (PR= 2.11), abrasion is related to age and poor dental hygiene habits (PR= 1.67 and 1.30, respectively). Conclusion: The presence of dental abrasion is greater than dental erosion. Age and poor dental habits are factors associated with tooth abrasion. The characteristics of saliva regarding pH and salivary flow were within normal p-values.

The evaluation of the oral health-related quality of life (OHRQoL) is important for clinical assessment and could be an indicator of the quality of the treatment received. Objective: To evaluate the OHRQoL in adults with removable prostheses in relation with patient characteristics such as age, sex, type and time of use of the prosthesis, previous experience and perception about the stability of the prosthesis. Materials and Methods: 217 patients from the Dental Clinic of the National University of San Marcos-Peru were evaluated after rehabilitation with a removable prosthesis. A structured questionnaire was applied by telephone interview. The evaluation of the OHRQoL was carried out using the General/Geriatric Oral Health Evaluation Index (GOHAI). For the statistical analysis, the Mann Whitney U test, the Kruskal-Wallis H test and the Spearman correlation were used. Results: The sample included 63 men (29%) and 154 women (71%) with an average age of 66.34. The average GOHAI score was 52.44+8.15. The GOHAI score was related to age (p=0.241), sex (p=0.110), type of prosthesis (p=0.069), previous experience (p=0.293), and perception of movement of the prosthesis (p<0.001). Conclusions: The GOHAI score indicates a moderate quality of life related to oral health after prosthetic rehabilitation. The GOHAI index can be considered effective for the evaluation of the OHRQoL.

Introducción: El plasma rico en plaquetas (PRP) es un biomaterial con alta concentración de plaquetas y factores de crecimiento que favorecen la regeneración de tejidos tras su aplicación en intervenciones quirúrgicas como la exodoncia del tercer molar. Material y métodos: El estudio se realizó con 20 pacientes con necesidad de exodoncia del tercer molar inferior bilateral. Las exodoncias se realizaron en un mismo tiempo quirúrgico y en uno de ellos, escogido aleatoriamente, se aplicó el gel de PRP y el otro tomado como grupo control. La evaluación posoperatoria se llevó acabo posterior a los tres meses; los parámetros evaluados fueron: dolor posoperatorio, curación de herida y densidad ósea mediante tomografía computarizada Cone Beam. Resultados: El dolor posoperatorio durante el tercer día, primera y segunda semana presentó menor grado en los sitios de aplicación de PRP que el grupo control (p<0,05. La densidad ósea medida por la tomografía computarizada Cone Beam evidenció ser mayor en los sitios de aplicación de PRP que el grupo control (p<0,05). Conclusión: El PRP posee efecto en la disminución del dolor posoperatorio y aceleración en la cicatrización de herida. Además evidencia mayor densidad ósea en comparación con la no aplicación del PRP.
