Two hundred forty interdental papilla sites in 20 healthy patients were investigated. Interdental papilla heights of maxillary anterior teeth were measured from the gingival zenith, along with clinical crown lengths. Percentages of papilla height to crown length were computed and defined as papilla proportion, mesial papilla proportion (MPP), and distal papilla proportion (DPP). Mean interdental papilla heights of maxillary anterior teeth were 4 mm mesially and 4.1 mm distally. Mean MPP was 42% (n = 120), and mean DPP was 43% (n = 120). No significant differences were found between MPP and DPP for maxillary incisors (P >/= .5). Canines demonstrated a trend toward increased distal papilla heights. Papilla proportions were approximately 40% for all tooth groups. A more apical position of distal papilla heights from anterior to posterior teeth, mentioned in the literature, was not confirmed by the present data.
对20名健康患者的240个牙间乳头部位进行了研究。从上颌前牙的牙龈顶点测量牙间乳头高度，并测量临床冠长。计算牙间乳头高度与冠长的百分比，并将其定义为乳头比例、近中乳头比例（MPP）和远中乳头比例（DPP）。上颌前牙的平均牙间乳头高度近中为4mm，远中为4.1mm。平均MPP为42%（n = 120），平均DPP为43%（n = 120）。上颌切牙的MPP和DPP之间未发现显著差异（P≥0.5）。尖牙显示出远中牙间乳头高度增加的趋势。所有牙组的乳头比例约为40%。文献中提到的从前往后牙远中牙间乳头高度更根尖的位置，本数据未得到证实。
