This study was designed to determine whether the distance from the base of the contact area to the crest of bone could be correlated with the presence or absence of the interproximal papilla in humans. A total of 288 sites in 30 patients were examined. If a space was visible apical to the contact point, then the papilla was deemed missing; if tissue filled the embrasure space, the papilla was considered to be present. The results showed that when the measurement from the contact point to the crest of bone was 5 mm or less, the papilla was present almost 100% of the time. When the distance was 6 mm, the papilla was present 56% of the time, and when the distance was 7 mm or more, the papilla was present 27% of the time or less.
本研究旨在确定接触区底部至牙槽嵴顶的距离是否与人类邻间隙乳头的存在与否相关。共检查了30例患者的288个部位。如果在接触点根尖方向可见间隙，则认为乳头缺失；如果组织充满楔状隙，则认为乳头存在。结果显示，当从接触点至牙槽嵴顶的测量距离为5mm或更小时，乳头几乎100%存在。当距离为6mm时，乳头存在的时间为56%，当距离为7mm或更大时，乳头存在的时间为27%或更少。
