Intermediate restorative material (IRM) is the appropriate choice for treating reversible pulpitis in permanent teeth because it is specifically designed for short-term use and provides an effective seal and protection for the pulp. IRM has properties that make it suitable for managing pulp inflammation by providing a temporary barrier that minimizes thermal and chemical stimuli.

This material is often used in situations where the pulp is still vital, and there is potential for healing. It allows for some moisture control and can be easily placed in areas with limited access, which is often the case in posterior teeth. The composition of IRM also contains eugenol, which has soothing properties on the pulp tissue, further aiding in the management of symptoms associated with reversible pulpitis.

In contrast, glass ionomer cement can release fluoride and bond chemically to dentin but may not provide the same degree of pulpal protection or be as effective in managing symptoms as IRM. Composite resin is better suited for permanent restorations and can be more technique-sensitive than IRM. Amalgam, while durable, is less commonly used for reversible pulpitis treatment due to its non-bonding nature and lack of pulpal soothing properties compared to IRM. Therefore, IRM stands out as the most suitable material in this context.
