Why might a dental assistant need to use their non-dominant hand during coronal polishing?

Using the non-dominant hand during coronal polishing serves as a method for better angling and stabilization. This technique enables the dental assistant to maintain a more controlled and steady approach while polishing the tooth surfaces. The non-dominant hand can assist in positioning the dental instrument at the correct angle, which enhances visibility and access to various areas of the mouth. Furthermore, stabilizing the instrument with the non-dominant hand allows for a more precise application of the polishing paste and prevents unnecessary movement that could lead to uneven polishing or discomfort for the patient. Therefore, the combination of improved angling and stabilization achieved by using the non-dominant hand is crucial for effective coronal polishing procedures.
