The smile is a standard by which individuals often are judged. Gingival display is an important component of the smile. While perceptions vary between the sexes and between laypeople and dental professionals, gingival display of ≥4 mm has been considered excessive and unattractive. The amount of gingiva that an individual displays can vary depending on the type of smile the individual produces. An emotional or forced smile will produce greater upper lip movement and gingival display than a posed smile. Much of the dental literature that discusses gingival display focuses on subjects of a limited age range, has a limited number of subjects, or neglects to determine the gingival display with maximum upper lip movement. The purpose of this prospective observational investigation was to document the smile type, gingival display, and upper lip movement of male and female subjects in different age groups.
微笑是人们经常评判的标准之一。牙龈显露是微笑的一个重要组成部分。虽然性别之间以及非专业人士和牙科专业人士之间的看法存在差异，但牙龈显露≥4 毫米被认为是过多和不美观的。个体所展示的牙龈量会因个体产生的微笑类型而异。情感或强制的微笑会比摆拍的微笑产生更大的上唇运动和牙龈显露。许多讨论牙龈显露的牙科文献都集中在年龄范围有限的受试者上，受试者数量有限，或者忽略了用最大上唇运动来确定牙龈显露。本前瞻性观察研究的目的是记录不同年龄组男性和女性受试者的微笑类型、牙龈显露和上唇运动。
