title: Training on synthetic ethylene-vinyl acetate bench model allows novice medical students to acquire suture skills.
abstract: OBJECTIVE
  To assess the acquisition of suture skills by training on ethylene-vinyl acetate bench model in novice medical students.
  
  
  METHODS
  Sixteen medical students without previous surgery experience (novices) were randomly divided into two groups. During one hour group A trained sutures on ethylene-vinyl acetate (EVA) bench model with feedback of instructors, while group B (control) received a faculty-directed training based on books and instructional videos. All students underwent a both pre-and post-tests to perform two-and three-dimensional sutures on ox tongue. All recorded performances were evaluated by two blinded evaluators, using the Global Rating Scale.
  
  
  RESULTS
  Although both groups have had a better performance (p<0.05) in the post-test when compared with the pre-test, the analysis of post-test showed that group A (EVA) had a better performance (p<0.05) when compared with group B (control).
  
  
  CONCLUSIONS
  The ethylene vinyl acetate bench model allowed the novice students to acquire suture skills faster when compared to the traditional model of teaching.
