To evaluate the relationship between gingival phenotype and tooth location based on selected index teeth ("Ramfjord") and assess possible differences between women and men.
Thirty-six women and 20 men voluntarily participated in this investigation with an average age of 23 years (min: 19; max: 37). Gingival phenotypes (GP) were assessed by transparency of a periodontal probe through the buccal gingival margin.
A comparable and similar GP on all index teeth was only found in seven out of the 56 subjects, that is, thin or thick only: Five participants (three male/two female) showed a uniform and constantly thick and two females a constantly thin GP. While the majority of molars (94.6%; p = 0.006) showed a thick GP, premolars (61.6%; p = 0.09) as well as incisors (70.5%; p = 0.046) were predominantly categorized as thin. In addition, significantly thicker GP was in general observed for maxillary teeth (p = 0.001) but without differences between genders (p = 0.722).
No constant GP can be expected within one dentition. The use of the "Ramfjord teeth" may serve as a quick overview and reliable method to screen GP distribution.
评估基于选定的指数牙（“Ramfjord”）的牙龈表型与牙齿位置之间的关系，并评估女性和男性之间可能存在的差异。
36 名女性和 20 名男性自愿参与了这项研究，平均年龄为 23 岁（最小：19；最大：37）。通过牙周探针通过颊侧牙龈边缘的透明度评估牙龈表型（GP）。
在 56 名受试者中，仅有 7 名受试者在所有指数牙上具有可比且相似的 GP，即仅为薄或厚：5 名参与者（3 名男性/2 名女性）表现出均匀且始终较厚的 GP，而两名女性则表现出始终较薄的 GP。虽然大多数磨牙（94.6%；p=0.006）表现出较厚的 GP，但前磨牙（61.6%；p=0.09）和切牙（70.5%；p=0.046）则主要归类为薄。此外，上颌牙齿的 GP 通常更厚（p=0.001），但性别之间没有差异（p=0.722）。
在一个牙列中不能期望有恒定的 GP。使用“Ramfjord 牙齿”可以作为快速概述和可靠的方法来筛选 GP 分布。
