Which of the following tools is NOT recommended to remove gingival flash?

The correct answer is that the football or round bur is not recommended for removing gingival flash. The reason for this is primarily related to the design and function of these burs. Football and round burs have a bulkier structure that can easily remove more tooth structure than intended, which increases the risk of damaging surrounding tissues and compromising the integrity of the tooth itself.

In contrast, instruments such as a scalpel blade, points, or flame-shaped burs, and sandpaper finishing strips are specifically designed for more precise removal of excess material in tight areas without the risk of overcutting or harming the gingiva. These tools allow for careful manipulation and finer control, which is essential in maintaining the health of gingival tissues while efficiently managing gingival flash.

Using the appropriate tools can prevent trauma to the gingiva and ensure a clean, aesthetically pleasing finish in restorative procedures, highlighting the importance of selecting the right instrument for specific tasks in dental care.
