Impact of Procedure Specific Videos in the Performance of Restorative Procedures by Pre-Clinical dentistry Students

Abstract

OBJECTIVE: With the advances in technology the teaching process needs to be improved. Video assisted learning has become an integral part of effective teaching. Using procedural or instructional videos have shown to augment student's preparedness for real life clinical practice and helps them to improve their skills at their own pace and learning ability. The aim if this study was to assess the impact of procedure-specific video demonstrations on the performance of pre-clinical dentistry students. METHODOLOGY: It was a cross-sectional experimental study conducted at the Pre-Clinical Operative Dentistry Phantom Lab at Bahria University Medical and Dental College Karachi, Pakistan. 50 students were divided equally into group A and group B (25 students in each group) by convenience sampling. Both groups prepared class 1 cavity and restored with amalgam. Group A were taught by a hands-on demonstration whereas Group B were taught by live demonstration as well as a procedurespecific video. The students were analyzed for the quality of their practical work as well as their understanding of key concepts. IBM statistics version 20 was used to carry out the statistical analysis. Pearson Chi Square test and independent T test were used, a p-value less than 0.05 was considered significant. RESULTS: Group A's assessment regarding cavity preparation showed that majority students of the group (n=11) required crucial changes in cavity design. For group B most students (n=9) reproduced important factors of cavity design however improvement was required. For amalgam filling, Group A and B's majority students had similar results. t-test was conducted and significant difference was found in the overall performance scores for group A (M=6.7, SD=1.7) and group B (M=8.0, SD=2.3); t-test p=0.04. CONCLUSION: This study suggests that video assisted learning as an additional tool to traditional teaching, can augment understanding and learning process of students.

Estrategias didácticas para el aprendizaje significativo y el desarrollo de habilidades prácticas en Operatoria dental, en estudiantes de Odontología. Revisión sistemática

“…Se incluyeron 11 artículos en esta revisión, que fueron publicados entre 2016 y 2023. Cuatro de estos artículos tenían un diseño de ensayo clínico aleatorizado (Iqbal et al, 2022;Khattak et al, 2022;Leitmann et al, 2020;Lukas et al, 2019), dos eran experimentales sin aleatorización (Su Yin et al, 2021;Zakhary et al, 2023), y el resto eran estudios observacionales (Al-Zain et al, 2021;Farag & Hashem, 2021;Khan et al, 2019;Sadid-Zadeh et al, 2019;Schwibbe et al, 2016).…”

“…Todas las investigaciones analizadas se realizaron con universitarios de la carrera de odontología, del área preclínica, e incluyeron en total 1006 estudiantes, de países como Arabia Saudí (Al-Zain et al, 2021;Iqbal et al, 2022;Khattak et al, 2022), Estados Unidos (Lukas et al, 2019;Sadid-Zadeh et al, 2019;Zakhary et al, 2023), Alemania (Leitmann et al, 2020;Schwibbe et al, 2016), Egipto (Farag & Hashem, 2021), Pakistán (Khan et al, 2019) y Tailandia (Su Yin et al, 2021).…”

“…Con respecto a las técnicas didácticas utilizadas se encuentran la simulación háptica de realidad virtual (HVRS) (Farag & Hashem, 2021), demostraciones en video (Iqbal et al, 2022;Khan et al, 2019;Lukas et al, 2019), aprendizaje electrónico (Iqbal et al, 2022;Khattak et al, 2022), demostraciones prácticas en modelos anatómicos (Schwibbe et al, 2016), los métodos Peyton: demostración-deconstrucción-comprensión, con verbalización por parte del alumno y el ciclo PDCA/Círculo de Deming: Planificar-Hacer-Verificar y Actuar, con automonitoreo asistido por video (Leitmann et al, 2020)…”

“…De acuerdo a los autores consultados, el uso de métodos didácticos reportan un beneficio, que se traduce en menor tiempo de aprendizaje y una optimización en el desempeño y adquisición de habilidades prácticas en operatoria dental (Al-Zain et al, 2021;Farag & Hashem, 2021;Iqbal et al, 2022;Khan et al, 2019;Khattak et al, 2022;Leitmann et al, 2020;Lukas et al, 2019;Sadid-Zadeh et al, 2019;Schwibbe et al, 2016;Su Yin et al, 2021;Zakhary et al, 2023).…”

Enhancing the lab skills of Dental Students: A Blended Learning approach

“…The impact of video-assisted learning for speci c procedures of cavity preparation in the Operative Department was also signi cant in research by Khan et al at the University of Bahria Medical and Dental College in 2019. 14 The students were analyzed for the knowledge and quality of practical work of class 1 Cavity preparation. One group was taught by live demonstrations and the experimental group was taught by a combination of live demonstrations and educational videos.…”
