What technique is used by dentists to open fissures and remove minimal decay?

1. Micropower application

2. Microabrasion

3. Ultrasonic scaling

4. Cavity preparation

The correct answer is: Microabrasion

The technique utilized by dentists to open fissures and remove minimal decay is microabrasion. This method employs a combination of a mild abrasive material and a carefully controlled stream of air or water to gently remove surface enamel and decay without the need for more invasive drilling techniques. Microabrasion is particularly effective for treating early caries and enhancing the aesthetics of teeth by removing discoloration or superficial stains, making it a conservative approach to dental care. In contrast, other techniques serve different purposes. Micropower application generally refers to various dental tools and may not specifically address the removal of decay. Ultrasonic scaling is primarily used for the removal of tartar and plaque from the teeth, focusing on periodontal health rather than decay within fissures. Cavity preparation involves more extensive drilling to prepare a tooth for restorative procedures, which is not suitable for handling minimal decay. Thus, microabrasion stands out as the appropriate choice for its targeted and conservative approach to manage early decay in fissures.
