Abstract
This study purposes to develop and assess a training program for pre-clinical manual dexterity. In order to achieve this objective, two experimental studies will be carried out. The first study will be performed in order to determine the most effective method to evaluate manual dexterity in dental students prior to pre-clinical training. The variable of interest is the manual dexterity, measured by O'Connor Finger Dexterity Test - Model 32021, Purdue Pegboard Test - Model 32020A, Dental Manual Dexterity Assessment - DMDA, Class One Cavity Preparation Assessment - COCA e Class One Composite Resin Restoration Assessment - COCRA. The second study aims to develop and evaluate the effect of a training program of manual dexterity in dental students on their manual dexterity, visual perception of depth and extension, self-confidence perception, quality of cavity preparations and students' working posture, prior to pre-clinical training. The dependent variables will be the manual dexterity assessed by Dental Manual Dexterity Assessment - DMDA, the depth and extension perception measured by Depth and Extension Perception in Dentistry test - DEPD, the self-confidence perception evaluated by VAS scale, the quality of Class I cavity preparation, assessed by COCA, the angulation of the subjects' necks and the working distance between the operator's eyes and the dental mannequin's mouth, measured by the software known as Software para Avaliação Postural - SAPO. Additionally, these variables will be evaluated in two different times: before and after the program implementation. The independent variable will be the training program of pre-clinical manual dexterity during work with direct and indirect vision. For both studies the descriptive statistics will be performed and the assumptions of normality and homoscedasticity will be verified. In the first study, the mean score obtained by the quality of cavity preparation and its restoration will be considered as gold standard. Thus, the sensitivity, specificity, and positive (LR+) and negative (LR-) likelihood values and accuracy of the tests will be estimated. A ROC curve will be constructed, and a cut-off point that maximize the predictive ability of each dexterity test will be determined. The area of the curve (AUROC) will be also calculated to determine the discriminatory capacity of these tests. The calculations will be performed according to the point and with 95% confidence intervals. In the second study, if the assumptions of normality and homoscedasticity met, the paired t-test will be performed. The significance level will be 5%. (AU)
