What is the primary use of IRM in dental practice?

The primary use of IRM (Intermediate Restorative Material) in dental practice is indeed as a sedative base for temporary restorations. This material is specifically designed to provide not only a seal but also relief from sensitivity in teeth that may be pulpal affected. Due to its properties, IRM is often utilized when a dentist wants to place a temporary restoration while allowing for the treatment of underlying dental issues or waiting for the patient to return for more definitive restoration. Its formulation includes zinc oxide and eugenol, which lend sedative effects, helping to soothe the pulp and reduce discomfort.

While IRM does exhibit adhesion qualities and can act as a temporary filler, its primary role centers around providing sedation and protection for vulnerable teeth. This differentiates it from permanent restoration materials, which are designed for longevity and strength, and from antibacterial fillers, which are not its main function but might be part of other restorative materials. Thus, the classification of IRM as a sedative base highlights its unique role in treatment planning and patient comfort in dental practice.
