Which condition is described as rare in prevalence?

• A. Osteonecrosis
• B. Osteoporosis
• C. Gingivitis
• D. Caries

Answer: (A)

Prevalence is about how widespread a condition is in the population. Osteonecrosis of the jaw is far less common than the other conditions listed; it mainly appears as a rare complication in specific high-risk groups, such as people on high-dose IV bisphosphonates or denosumab for cancer, or after head and neck radiation. In contrast, osteoporosis affects a large portion of older adults, gingivitis is common in many people with gums, and dental caries remains one of the most prevalent oral diseases worldwide. Because of this, osteonecrosis stands out as the rare condition.
