How should temporary restorations be removed by an LDA?

1. With the use of chemical solvents

2. With hand instruments only

3. By mechanical drilling

4. Any method available

The correct answer is: With hand instruments only

Temporary restorations should be removed by a Licensed Dental Assistant (LDA) using hand instruments only because this method allows for greater control and precision when handling delicate tooth structures. Hand instruments minimize the risk of causing further damage to the tooth or surrounding tissues, which is especially important when dealing with temporary materials that may be more easily displaced or damaged. Using hand instruments also aligns with best practices in dental safety and patient care, ensuring that the procedure is performed effectively while reducing the chances of complications that could arise from more aggressive methods, such as drilling. Other methods, such as chemical solvents or mechanical drilling, introduce potential for harm. Chemical solvents could unintentionally affect the underlying tooth structure or leave residues, while mechanical drilling may create more significant risks of damage or injury. The option that permits the use of any method isn't ideal as it neglects the need for a standardized and safe protocol in dental procedures. Therefore, utilizing hand instruments only is the recommended and safest practice for LDA professionals when it comes to removing temporary restorations.
