Coronal Polish Certification Practice Test

The presence of enamel scratches is a sign of improper technique during coronal polishing because it indicates that the polishing is being performed too aggressively or with an inappropriate tool. The goal of coronal polishing is to enhance the polish of the enamel without causing damage. When scratches occur, it means that the abrasive agents or instruments used may have been too harsh, compromising the integrity of the tooth surface.

In contrast, other signs such as too much plaque remaining on teeth or bleeding gums could indicate different issues, such as inadequate cleaning or potential underlying periodontal disease, rather than directly reflecting polishing technique. Increased patient comfort is typically an indication of proper technique since a well-executed coronal polish should be a gentle and comfortable experience. Therefore, the presence of enamel scratches is the most direct indicator of improper technique in this context.
