Which instrument is typically used for coronal polishing?

Coronal polishing is a procedure used to remove plaque and stains from the surfaces of teeth, primarily focusing on the enamel. The instrument that is typically used for this procedure is a polishing handpiece with a cup attachment. This specialized handpiece allows for the precise application of polishing paste, ensuring effective cleaning of the tooth surfaces while also being safe for the enamel. The cup attachment is designed to hold the polishing paste and rotate at high speeds, providing an efficient and thorough polish.

In contrast, a dental scaler is used for removing calculus and tartar from the teeth, not for polishing. An ultrasonic cleaner is a device used for cleaning instruments, not for performing coronal polishing on teeth. A dental mirror, while instrumental in helping the clinician visualize the teeth during procedures, does not participate in the actual polishing process. Thus, the polishing handpiece with a cup attachment is the appropriate choice for coronal polishing as it combines both speed and effectiveness needed for the procedure.
