Aim: The purpose of this study was to determine the accuracy of two types (friction style and spring style) of mechanical torque wrenches after clinical use. Materials and Methods: Four mechanical torque wrenches in clinical use were collected. Two were friction style and two were spring style. All the wrenches had been in use for at least 6 months without being recalibrated and were tested to check their accuracy in delivering target torque values. The data obtained were statistically analyzed using Student's t-test. Results: After clinical use, there was no statistically significant difference in the accuracy between the two groups (P < 0.05). Conclusions: Within the limitations of this study, it was concluded that after clinical use, the accuracy of both the type of wrenches was within clinically acceptable limits. All torque wrenches delivered torque values within 10% of the target torque value.
