Final answer:
Cheilitis can be associated with increased interocclusal space, and treatment typically involves dental interventions along with measures to protect the lips.
Step-by-step explanation:
Cheilitis, which refers to inflammation of the lips, can occasionally be associated with increased interocclusal space, which is the vertical distance between the upper and lower teeth when the mouth is at rest. To treat cheilitis, it is important to address the underlying cause. If the increased interocclusal space is due to loss of tooth height from wear, erosion, or loss of teeth, dental interventions such as occlusal rehabilitation with crowns, bridges, or dentures might be necessary. In some cases, simple measures like barrier ointments and avoiding lip irritants can also be effective. It is essential to consult with a dental or medical professional to determine the appropriate treatment.
