Plastic

Discs allow us to perform many functions with more precision and safety compared to highspeed rotary finishing instruments such as burs and diamonds. Included in the list are:

• Refine incisal edges and embrasures.
• Smooth the junction between composite and the tooth without significantly affecting the enamel surface.
• Remove sharp angles on crown and onlay preparations.
• Remove excess resin cement from margins without altering the restoration or the tooth.
• Remove resin cement from teeth when debonding orthodontic brackets.

All discs in this category use aluminum oxide or silicon carbide as the abrasive on a plastic backing.

Wet vs. Dry

This choice is a matter of personal preference, since equal results can be achieved with and without water as a lubricant/coolant. However, if you are using the disc to remove overextended composite, dry finishing will give you a better view of where the composite ends and tooth begins. With dry finishing, be sure to suction the dust generated as you are using the instrument. While the health effects of inhaling composite dust are not well-established, suctioning it to stay on the safe side seems to be prudent.

Effectiveness

We used each system to finish and polish Class V universal composite restorations in Ivorine teeth and rated them for gloss based on the 0-5 scale we developed, with 5 being an enamel-like sheen. Unlike the polishing results with rubber-like instruments, there was not much difference between the brands and, therefore, these results did not influence the product's rating, which also takes into account ease of use. Nevertheless, the results are listed under each product's commentary.
