Macroscopic changes of the lips in the edentulous elderly subject are accompanied by variations in their microvascularisation. This study was undertaken on histological or clarified sections from totally edentulous subjects whose vascular system was injected with Indian ink agar. A reduction in density and size of the superficial (papillary or mucosal) and deep (reticular or submucosal) networks is observed with age. These changes are to be seen in relation to imaging and to the reduction in occlusal potential of the lips.
无牙老年受试者嘴唇的宏观变化伴随着其微血管化的改变。本研究对完全无牙受试者的组织学切片或透明切片进行，这些受试者的血管系统用印度墨汁琼脂灌注。随着年龄增长，可观察到浅表（乳头层或黏膜层）和深部（网状层或黏膜下层）网络的密度和大小降低。这些变化与影像学以及嘴唇咬合功能的降低有关。
