MOD inlays are characterized by which of the following?

MOD inlays are characterized by their coverage of the whole occlusal surfaces and the mesial and distal surfaces of a tooth. The term "MOD" refers to the combination of mesial, occlusal, and distal surfaces involved in the restoration. These inlays are designed to restore teeth that have extensive carious lesions or have been structurally compromised while still retaining the tooth's bulk and anatomy.

When considering the other options, the first option states that MOD inlays only cover the occlusal surface, which is incorrect because they involve more than just the occlusal surface; they encompass both the mesial and distal aspects as well. The second option suggests that MOD inlays do not cover centric cusps, but that is also inaccurate, as the design of these inlays does include the coverage of the centric cusps to restore functional integrity. The idea that MOD inlays are used only for anterior teeth is incorrect because MOD inlays are primarily used for posterior teeth, which require significant restoration due to the higher incidence of carious lesions and structural damage in those areas.

Thus, MOD inlays are accurately defined by their comprehensive coverage of the occlusal surfaces along with the adjacent mesial and distal surfaces, making them
