A patient with a class II cavity in the lower right second molar may discuss which of the following treatment options?

In the context of treating a class II cavity in the lower right second molar, the use of amalgam is a common and appropriate treatment option. Amalgam is particularly notable for its durability, strength, and resistance to wear, making it an excellent choice for posterior teeth that endure significant occlusal forces. Class II cavities, which involve the interproximal surfaces of posterior teeth, can benefit from the properties of amalgam because it provides good retention in these types of restorations and is less likely to fracture under chewing pressure compared to some other materials.

Furthermore, amalgam has a long history of successful use in dentistry, and although its cosmetic appeal is less than that of options like composite, its crucial functional characteristics make it favorable in this situation. It is worth noting that in certain cases, other materials such as composite could also be used, but ability to endure the stress exerted on a molar during function makes amalgam particularly suitable for this scenario.

Crown and extraction options may also be discussed in more extensive damage scenarios or if the tooth is compromised beyond what a filling can remedy, but for a typical class II cavity, amalgam restoration would typically be the focused treatment option.
