When a tooth is subjected to occlusal trauma, one of the common consequences is bone resorption, which relates to the process where the bone that supports the tooth begins to break down. This occurs due to the excessive forces placed upon the tooth, leading to an inflammatory response in the periodontal tissues. As a result, the body may initiate the resorption of alveolar bone around the tooth, aiming to reduce the stress on the tooth and the surrounding structures.

In the context of occlusal trauma, the increased bite pressure can cause irritation and damage to the periodontal ligament, triggering a cascade of biological responses. This may lead to the recruitment of osteoclasts, the cells responsible for bone resorption, which progressively diminishes the height and density of the supporting bone around the affected tooth.

In contrast, other options such as negligible changes, brittle structure, or increased mobility may not consistently result from occlusal trauma. Negligible changes would imply no significant effects, which is unlikely given the stress involved. Brittle structure is more associated with intrinsic quality factors of the tooth itself rather than occlusal forces. Increased mobility, while it can be a result of severe trauma, is not as definitive as bone resorption, which directly correl
