Final answer:
The answer is D. Rheumatoid arthritis is not associated with the fully edentulous state.
Step-by-step explanation:
The answer is D. Rheumatoid arthritis.
The fully edentulous state refers to the condition of being completely toothless, usually as a result of tooth loss and extraction. While conditions such as residual ridge reduction, decrease in masticatory function, and altered taste perception are commonly associated with the fully edentulous state, rheumatoid arthritis is not directly associated with the absence of teeth.
Rheumatoid arthritis is a chronic inflammatory disorder that primarily affects the joints, causing pain, stiffness, and swelling. It does not directly affect the oral cavity or result in tooth loss.
