Best finishing of composite done by:

• A. Carbide bur.
• B. Diamond bur.
• C. Mounted stone.
• D. Best retained under matrix band.

The best finishing of composite is done by: C. Mounted stone.

Here's why:

• Carbide burs are too aggressive and can easily over-cut the composite, leading to a rough and uneven surface.
• Diamond burs are also quite aggressive and can be difficult to control, especially for beginners. They can also leave scratches on the composite surface.
• Mounted stones are the most gentle and effective option for finishing composite. They come in a variety of grits and shapes, so you can choose the right one for the job. They are also less likely to scratch the composite surface.

Best retained under matrix band:

This option is not relevant to the question of the best finishing tool for composite. Matrix bands are used to hold the composite in place while it is being cured, and they are not used for finishing.

Here are some additional tips for finishing composite:

• Use a light touch and start with a coarse grit stone.
• Work in small circles and gradually move to a finer grit stone.
• Be careful not to overheat the composite, as this can damage it.
• Keep the composite wet while you are finishing it.
• Once you are finished, polish the composite to a high shine.
