Which statement best describes alveolar bone loss pattern with respect to quantity?

• A. Horizontal pattern only
• B. Vertical pattern only
• C. Generalized or localized
• D. None of the above

Answer: (C)

The key idea here is describing how widespread the bone loss is across the dentition, not the shape of the defect around individual roots. Generalized means bone loss involves most teeth, while localized means it affects only a few teeth or a specific area. This is about quantity or extent. The horizontal and vertical patterns describe how the bone loss is distributed around roots (directional/shape differences), not how much of the mouth is affected. So the statement that best captures the quantity aspect is generalized or localized.
