The purposes of this study were to quantify some clinical parameters that are useful as esthetic guidelines when the gingival contour is modified and to compare the left and right sides of the six maxillary anterior teeth.
Two hundred and forty interdental papilla sites in 20 healthy patients were evaluated. 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 teeth was 3.83 mm mesially and 3.8 mm distally. Mean MPP was 43.69% ( n = 120) and DPP was 44.57% ( n = 120). No significant differences were found between MPP and DPP for maxillary incisors ( P ≥ 0.5).
Papilla proportions were approximately 44% for all tooth groups. Canines demonstrated a trend toward increased distal papilla heights. In the present study the average MPP and DPP of the central incisor (CI), lateral incisor (LI) and canine (CA) measured were 43%, 41%, 46%, 40%, and 42% 51% respectively.
本研究的目的是量化一些临床参数，这些参数在牙龈轮廓改变时可作为美学指导，并比较上颌六颗前牙的左右两侧。
对20名健康患者的240个牙间乳头部位进行评估。从上颌前牙牙龈顶点测量牙间乳头高度以及临床冠长。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）。
上颌牙的平均牙间乳头高度近中为3.83mm，远中为3.8mm。平均MPP为43.69%（n = 120），DPP为44.57%（n = 120）。上颌切牙的MPP和DPP之间未发现显著差异（P≥0.5）。
所有牙组的乳头比例约为44%。尖牙的远中乳头高度有增加的趋势。在本研究中，测量的中切牙（CI）、侧切牙（LI）和尖牙（CA）的平均MPP和DPP分别为43%、41%、46%、40%和42%、51%。
