“…Additionally, static positions are often riskier for the musculoskeletal system than dynamic movements in dentistry. Neves et al [ 32 ] found a significant correlation between the students’ difficulties in preclinical restorative procedures and their difficulties in maintaining an ergonomic posture. The results of a study by Diaz-Gaballero et al [ 7 ] showed that exaggerated body flexion or cervical torsion, performed to improve the view of the oral cavity, caused musculoskeletal pain among Colombian dental students.…”

Musculoskeletal disorder (MSD) is already prevalent in dental students despite their young age and the short duration of dental practice. The current findings state that the causes of MSD are related to posture during dental work. This study aims to investigate the ergonomic risk of dental students. In order to analyze the ergonomic risk of dental students, 3D motion analyses were performed with inertial sensors during the performance of standardized dental activities. For this purpose, 15 dental students and 15 dental assistant trainees (all right-handed) were measured in a team. Data were analyzed using the Rapid Upper Limb Assessment (RULA), which was modified to evaluate objective data. Ergonomic risk was found for the following body parts in descending order: left wrist, right wrist, neck, trunk, left lower arm, right lower arm, right upper arm, left upper arm. All relevant body parts, taken together, exhibited a posture with the highest RULA score that could be achieved (median Final Overall = 7), with body parts in the very highest RULA score of 7 for almost 80% of the treatment time. Dental students work with poor posture over a long period of time, exposing them to high ergonomic risk. Therefore, it seems necessary that more attention should be paid to theoretical and practical ergonomics in dental school.

“…En Brasil, un estudio llevado a cabo con 56 estudiantes que analizó el efecto del entrenamiento preclínico, constató mediante registros semanales utilizando una escala numérica análoga, una correlación entre la dificultad en realizar las maniobras preclínicas y las dificultades en adoptar en ellas, posturas ergonómicas. Asimismo se constató que la percepción de los estudiantes sobre la dificultad en implementar posturas ergonómicas disminuía con el correr de los días en el programa de entrena-miento (p<0.001) (37).…”

Introducción: los desórdenes músculoesqueletales tienen una alta prevalencia en la población general y en particular, en el área salud, los profesionales de la odontología representan una población altamente vulnerable, debido a características particulares del ejercicio de su profesión. Es creciente el estudio de diferentes intervenciones ergonómicas y el impacto que estas pueden tener sobre la reducción de la sintomatología muscular y en el desarrollo y/o la perpetuación de estos cuadros disfuncionales. Materiales y método: se realizó una revisión, de tipo narrativa, entre los meses de abril de 2022 y agosto de 2022. Se consultaron base de datos tales como MedLine/PubMed y Scielo, incluyendo artículos publicados en los últimos diez años. Resultados: se obtuvieron un total de 71 artículos, de los cuales, se excluyeron 30 trabajos, resultando en 41 los artículos incluidos en la presente síntesis cualitativa. Conclusiones: las intervenciones ergonómicas están dirigidas básicamente, a cambios en los ambientes de trabajo de los profesionales y/o a la implementación de programas que tienen como objetivo instruir y concientizar a los profesionales sobre criterios ergonómicos para su incorporación en el desempeño de su trabajo. Ambos enfoques intervencionistas, han sido evaluados con herramientas validadas de autopercepción, exámenes clínicos y evaluaciones instrumentales. Las estrategias que focalizan el problema, en los espacios de trabajo, y aquellas que, incluyen educación y formación en ergonomía, disminuyen el impacto de los desórdenes músculoesqueletales en esta población. Estas últimas, tienen la potencialidad de provocar cambios en los hábitos de los profesionales, con conductas que se mantienen a mediano plazo.

“…12,13 When preclinical training in restorative dentistry begins, many students do not have enough manual dexterity and self-confidence to face the first obstacles that arise in practical learning, which can result in difficulties in performing both preclinical procedures 10 and in adoption of ergonomic work postures. 14 The development of manual dexterity is essential for the practice of dentistry. However, if this process is not properly conducted, it may compromise the student's self-confidence and consequently his/her preclinical and clinical learning.…”

“…2 Thus, although the development of new motor skills may take time in the beginning, it is important that this occurs gradually and properly, under specialized professional guidance. 2,14,15 According to Duong et al (2010), 2 after the development of manual dexterity, operators master their notion of space, force and positioning while holding the instruments. Therefore, it is possible that the learning of clinical skills after this phase of fine motor development allows students to be concerned only with the new skill being learned, optimizing their learning process and application of ergonomic concepts.…”

The aim of this study was to develop and evaluate the effect of a manual dexterity training program on manual dexterity, perception of selfconfidence, quality of cavity preparations, and ergonomic work posture of dental students prior to preclinical training. Methods: Students in the first year of the undergraduate dentistry program (N = 63) participated in this study. The program consisted of eight phases in which students performed different types of activities. The dependent variables were: manual dexterity assessed by the modified Dental Manual Dexterity Assessment; self-confidence to perform a preclinical procedure using the VAS scale; quality of Class I cavity preparation; angular deviation from the neutral position of the neck, trunk, wrist and distance between the student's eyes and the mannequin's tooth. These variables were evaluated at two different times: before and after the application of the program. The independent variable was the preclinical manual dexterity training program. After meeting the assumption of normality, the paired t-Student test was performed, the significance level was 5%. Results:The results showed a statistically significant difference in relation to manual dexterity (p < 0.001), self-confidence (p < 0.001), quality of cavity preparations (p < 0.001), distance from the eyes of the student/mannequin (p < 0.001), deviation angle of the neutral position of the trunk (p = 0.007) and wrists (p < 0.001), with better results in posttraining. Conclusion: It was possible to conclude that, in general, the proposed training positively influenced the self-confidence, dexterity, quality of work, and ergonomics of the evaluated students.
