Objective: Handgrip and pinch grip are the functional units of dentists used in the firm holding of instruments and tools. The main objective is to find the correlation between the menstrual cycle and grip strength in dental students.
Methodology: This study has been reviewed by the Ethics Committee of Non-Interventional Researches of the Cukurova University and its ethical conformity has been approved (6.10.17.TS69.KN29). Subjects were 1st grade (n=31) and 5th grade (n=39) female dental students (N=70) from Cukurova University Faculty of Dentistry, Adana. Cycle phases were divided into the early and mid‐follicular, mid‐cycle (ovulatory). Cycle phases were estimated from the first day of the menstrual bleed. Measurements included handgrip strength and lateral pinch grip strength. Handgrip strength was measured by a hydraulic hand dynamometer in kilogram unit and pinch grip strength was measured by pinchmeter in kilogram unit.
Result: The comparison of the first and second measurement differences (second - first) according to the classes was examined by Mann Whitney U test. There were no significant differences handgrip strength for right (p=0,157) and left (p=0,935) hands. There were no significant differences pinch grip strength for right (p=0,275) and left (p=0,971) hands (p<0,05).
Discussion and conclusion: The results of this study demonstrated that the phases of the menstrual cycle had no adverse effect on handgrip strength and lateral pinch grip strength in dental students.
