HOSA Dental Terminology Practice

What is an inlay in dental terminology?

1. A type of dental implant

2. A restoration involving some occlusal and proximal surfaces

3. A type of adhesive used in fillings

4. A surgical procedure to repair gums

The correct answer is: A restoration involving some occlusal and proximal surfaces

An inlay in dental terminology refers to a type of indirect restoration used to repair a tooth that has been damaged or affected by decay. It is specifically designed to fit within the confines of a cavity preparation, covering some occlusal (biting surface) and proximal (side) surfaces of the tooth. Inlays are typically made from materials like porcelain, gold, or composite resin, and they are custom fabricated in a dental laboratory based on an impression taken from the patient's tooth. The technique involves first removing the decayed or damaged portion of the tooth, then taking an impression to create the inlay. Once completed, the inlay is bonded directly to the tooth, restoring its function and appearance. This type of restoration is ideal for cavities that are too large for a standard filling but do not require a full crown. This definition directly addresses the role of an inlay in restorative dentistry, emphasizing its location and function in the structure of the tooth. Other choices, such as a type of dental implant, adhesive used in fillings, or a surgical procedure to repair gums, describe different dental concepts that do not align with the specific purpose and application of an inlay.
