“…Fifteen extrinsic muscles and 11 intrinsic muscles are associated with hand function [1]. Extrinsic muscles directly contribute to the gross motor motion of the upper extremity and gripping force, while intrinsic muscles regulate fine motor coordination of the digits [10].…”

“…In previous studies on grip strength, the number of taps of the third finger correlated with the muscle mass of the body, and muscle mass has been reported to be significantly related to manual dexterity 10,11) . Although grip strength is also an indicator of manual dexterity, tapping of the third finger might possibily be a stronger factor affecting the lateral preparation of the beginner's dentists.…”

Background: Manual dexterity is important for dentists. However, few studies have investigated the relation between dental skills and manual dexterity. The hypothesis of the present study is that an association exists between manual dexterity and the accuracy of cavity preparation.Methods: Fifty-two dental students (25 males, 27 females) participated in this study. All subjects completed manual dexterity tasks (i.e., grip strength, pinch force, and number of taps made by fingers of the right hand) and a preparation accuracy test using Virtual Reality Systems (VRS, Simodont®). For the preparation test, the cross-block body in Simodont's Manual Dexterity section was used. The associations between erroneous preparations (i.e., errors in the lateral and vertical directions) and the results of manual dexterity tasks were then analyzed and examined. Result:The results revealed that grip strength and number of taps made by the fingers correlated with lateral direction errors. In particular, the number of taps in the first 10 s from the start of tapping made by the third finger, which the participants used as a finger rest during preparation, demonstrated a significant correlation with lateral direction errors. Conclusion:In this work, tapping was revealed to be associated with manual dexterity by quantifying the accuracy of preparation. In addition, the agility of the third finger used as a finger rest appeared to affect accuracy in the lateral direction. VRS is useful not only indeveloping teaching strategybut also in research on cavity preparation.

“…The causes of deterioration in the motor control ability according to aging have been estimated to be the partial structural change in fingers, and nervous system change (Galganski et al, 1993;Carmeli et al, 2003). A CFE test can evaluate the change in function of the nervous system.…”

Objective: The purpose of this study is to build basic data to systematically develop a hand function evaluation tool by determining the effects of age, gender and target force level on the difference in hand function according to the target force level.Background: Precise and objective evaluation of hand functionality is a very important factor in quantifying treatment progress in patients or elderly people, and in verifying treatment effects. However, most hand function evaluations lack objectivity and accuracy, and therefore it is difficult to properly treat patients according to the given situation.Method: Sixteen healthy subjects (eight elderly and eight young people) participated in this study to evaluate the effects of age, gender, and target force level on tracking performance through rRMSE in terms of the tracking force and actual exerted force, by carrying out a task of maintaining six different target force levels for 20 seconds.Results: The result of this experiment indicated that elderly people and women had a lower ability to maintain a certain level of force than young people and men by 16% and 10%, respectively. The target force level results showed that the tracking error of the lowest force level (5% MVC) was significantly higher than that of 15% MVC, which in turn showed a higher tracking error than that of the higher target force levels. Conclusion:The results of this study can thus be utilized to develop a rehabilitation program for elderly people or other patients.Application: The authors expect that the results of the present study will be valuable to develop a rehabilitation program and hand function evaluation tool.
