HOSA Dental Terminology Practice

Which of the following best describes the function of resin in dentistry?

1. A hardening agent for teeth

2. A filler for cavities

3. A plastic type material used for dental appliances

4. A method for whitening teeth

The correct answer is: A plastic type material used for dental appliances

Resin in dentistry is primarily utilized as a plastic-type material that is incorporated into various dental appliances. This includes products such as dental sealants, composite fillings, and orthodontic retainers. The unique properties of dental resin allow it to be molded and shaped to fit specific dental applications while providing durability and aesthetic appeal, as it can be color-matched to natural teeth. Resin’s versatility makes it an essential component in modern dentistry, particularly in restorative procedures where the goal is to repair or enhance the structure and appearance of a tooth. Its ability to bond to tooth structure also facilitates effective repairs and modifications, contributing significantly to overall oral health. While resin can be used in some contexts to assist with cavity filling, specifically composite resins that can act as fillers, its primary classification as a plastic-type material widens its applicability beyond just filling cavities to a broader range of dental solutions.
