Oklahoma Pit and Fissure Sealants State Practice Exam

What device can make it easier for a patient to maintain an open mouth during a procedure?

1. Dental spatula

2. Bite block

3. Dental mirror

4. Patient napkin

The correct answer is: Bite block

The bite block is specifically designed to help patients maintain an open mouth during dental procedures. This device fits comfortably between the teeth, providing support and preventing the patient from unintentionally closing their mouth. By keeping the mouth open, the bite block gives the dentist better access to the oral cavity, allowing for various treatments to be performed more effectively and comfortably. In contrast, the other options do not serve this purpose. A dental spatula is primarily used for mixing or applying materials rather than assisting with mouth position. A dental mirror is useful for sight and visualization inside the mouth but does not aid in keeping it open. A patient napkin provides protection for the patient's clothing during treatment but is not involved in maintaining mouth position. Thus, the bite block stands out as the correct tool for facilitating an open mouth during dental procedures.
