Aging is associated with alveolar bone loss in female C57BL6/JNia mice. Representative a, b palatal and c, d buccal aspect microCT scans of alveolar bone in young (2–3 month) and old (24 month) mice. Yellow lines represent distance between the cementoenamel junction (CEJ) to the alveolar bone crest (ABC) as landmarked by an observer who was blinded to the identity of each animal. The larger distance in panel d compared to panel c is indicative of alveolar bone loss in the aged animal compared to the young animal
