ABSTRACT

Research is defined as “ a systematic inquiry to describe, explain, predict, and control the observed phenomenon. It involves inductive and deductive methods”, According to the American sociologist Earl Robert Babbie. Research application in the medical and dental sectors has grown in prominence and is currently being encouraged, particularly among undergraduate students. The past ten years have seen a significant expansion in the field of dentistry due to the introduction of several novel problems, solutions, and techniques. Regrettably, there is a present talent gap for dental scientists, and the talent market for dentists is becoming less competitive. In a study it was quoted that about 85% of dental graduates opted for private practice over employment in research. This review article covers the importance of Research methodology knowledge in the Undergraduate Dental Students and the Barriers stopping the students from acquiring it.

ABSTRACT

Objetivos: El objetivo del presente trabajo fue analizar el nivel de eventos (estiramiento/fractura) en el instumental rotatorio endodonticode niquel- titanio después del uso en Practicas Preclínicas de Grado en dientes ex vivos y tacos de acrílico Materiales y métodos: Seseleccionaron alumnos de grado de la materia Endodoncia de cuatro comisiones (n= 60) que en las pruebas de apropiación deconocimientos y destrezas, superaron el valor de 7/10. A cada alumno se le entregó un kit de ProTaper Universal, nuevo para larealización de dos prácticas: 1° en tacos de acrílicos simuladores de piezas dentarias y 2° en una pieza unirradicular extraída de bajacomplejidad. Se evaluaron las series de limas S1, S2, F1, F2 y F3 en cada población. Se realizó una lectura macro de cada instrumentocon lupa 4X, efectuada por un operador entrenado. Previamente, se realizó en el unaevaluación de los instrumentos sin uso y luego de los estirados o fracturados. Para el análisis de eventos producidos en cada serie de limas seutilizó el Test de Chi cuadrado de homogeneidad con niveles de significación de p= 0,05 (sofware estadístico Infostat) Resultados: No seencontraron diferencias significativas entre las distribuciones de los eventos en dientes y en taco. (Test de Chi2 p=0.0957). En el primeruso, de un total de 300 instrumentos utilizados, 6 sufrieron un evento, siendo en el segundo uso de 270, 12 sufrieron un evento. Para cadainstrumento, las diferencias no resultaron estadísticamente significativas (p valor de Irwin Fisher) S1 p=0.29, S2 p=0.10, F1 p=0.33,F2 p=0.81, F3 p=0.81. Observamos la frecuencia de eventos por instrumento, surgiendo que son más frecuentes los eventos con F1 y F2que con los restantes instrumentos...


Objective: The aim of this study was to analyze the behavior (events: stretching/fracture) of Ni-Ti rotatory Endodontic instruments afterthe utilization in preclinical practice, either ex vivo teeth or acrilic dowels. Materials and methods: undergraduate Endodontic studentsbelonging to four different courses with higher califications (more than 7/10) have been selected (n = 60). Each student has been deliveredwith a brand new ProTaper Universal Kit with the purpose of carrying out two endodontic practices, 1° in acrilics dowels, simulating ateeth and, 2° in a natural low complexity single rooted teeth. The series of files S1, S2, F1, F2 y F3 were assessed in each population. Amacro observation with a 4x magnified lens was performed by a qualified operator. Previously, a MEB observation had been performed onthe brand new instruments and in the post-use stretched or fractured instruments. The Chi square test of homogenity with significancelevels of p = 0.05 have been utilized for the analysis of the events (Infostat Estatistical Software). Results: No significant differences hasbeen found between the event distributions (Teeth/Acrilics dowels) (Test Chi2 p = 0,0957). A total of 300 files used for first time, 6suffered some kind of event, while in the second, a total of 270 files, 12 suffered some kind of event (stretching/fracture). The differenceswere not statistically significant on each file (p = Irwin Fisher value) S1 p=0.29, S2 p=0.10, F1 p=0.33, F2 p=0.81, F3 p=0.81.The event for each instrument has been detected to be more frequent with files F1 and F2 than with other files...
