HESI General Chairside Assisting Practice Exam

Which items are needed to place pit and fissure sealants?

1. Hygiene kit, suction tip, articulating paper

2. Contra angle, occlusal brush, articulating paper

3. Instruments, light cure, bonding agent

4. Mirror, explorer, sealant gun

The correct answer is: Contra angle, occlusal brush, articulating paper

To successfully place pit and fissure sealants, one primarily requires instruments that facilitate both the application and the proper finishing of the sealant material. The selection includes specific tools designed for optimal function during the sealing process. The need for a contra angle is essential as it allows for better manipulation and control when using an applicator for the sealant. The occlusal brush is particularly useful for smoothing the surface of the sealant, ensuring that it is evenly distributed and well-adhered to the tooth structure. Articulating paper helps ensure that the sealant does not interfere with occlusion once set, which is important for patient comfort and proper dental function. The other offered materials do not primarily contribute to the actual placement of pit and fissure sealants. While tools like mirrors and explorers can assist in the examination and isolation of the tooth surface, they do not play a central role in the application of the sealant itself. Similarly, while a hygiene kit is helpful in maintaining an appropriate environment and suction might aid in visibility, they are not specific to the act of placing sealants. Therefore, the items needed for an effective and efficient sealant application are accurately encapsulated in the correct choice.
