Which condition may lead to a hyperoccluded tooth?

• A. Asymptomatic apical periodontitis
• B. Acute irreversible pulpitis
• C. Symptomatic apical periodontitis
• D. Chronic apical abscess

Answer: (C)

The condition that may lead to a hyperoccluded tooth is symptomatic apical periodontitis. This condition is characterized by inflammation and sensitivity at the apex of a tooth, often as a result of pulpitis or periapical infection. The inflammation can cause the surrounding tissues to become sensitive, leading to a change in how a person bites or occludes their teeth.

When a tooth becomes hypersensitive due to symptomatic apical periodontitis, an individual may unconsciously avoid biting on that tooth or may alter their chewing pattern, which can result in adjacent teeth or opposing teeth receiving more pressure than they normally would. This increased occlusal pressure may lead to hyperocclusion, where a tooth comes into contact with opposing teeth more than is typical during closure. Over time, this change in occlusal relationship can create a hyperoccluded situation.

In comparison, asymptomatic apical periodontitis typically does not present with symptoms that alter function or occlusion significantly. Acute irreversible pulpitis can result in significant pain but may not directly cause a change in occlusion unless there are other concurrent issues. A chronic apical abscess may lead to tissue destruction but does not necessarily cause hyperocclusion in the same manner as symptomatic apical periodontitis
