The interdental papilla may be lost or reduced in height, forming black triangles due to various reasons, which gives an unaesthetic appearance when the patient smiles. Various noninvasive and invasive techniques have been used to augment/reconstruct the interdental papilla, to reclaim the pink triangle. The most satisfactory and natural appearance can be obtained by augmenting or reconstructing the lost papilla as the pink esthetics is as important as the white esthetics.
Two female patients and 1 male patient reported to the dental department with the complaint of a small black gap in the gum area between their upper front teeth since 6 months and 1 year, respectively. On examination, the interdental papillae in all three cases were classified as class 1 (Nordland and Tarnow's). The interdental papilla was augmented surgically by using three different approaches in each case.
Postoperatively and after 1-month follow-up, there was a complete fill of the interdental area by the interdental papilla normal (Nordland and Tarnow's). As a result, the black triangle was successfully converted into a natural pink triangle in all three cases.
由于各种原因，牙间乳头可能会缺失或高度降低，形成黑色三角区，患者微笑时会显得不美观。已经采用了各种非侵入性和侵入性技术来增大/重建牙间乳头，以恢复粉红色三角区。由于粉红色美学与白色美学同样重要，通过增大或重建缺失的乳头可以获得最令人满意和自然的外观。
两名女性患者和一名男性患者分别因上前牙牙龈区域出现小黑间隙6个月和1年而到牙科就诊。检查时，所有三例的牙间乳头均被分类为1类（诺德兰和塔诺分类法）。在每例中分别采用三种不同方法通过手术增大牙间乳头。
术后及1个月随访后，牙间乳头正常（诺德兰和塔诺分类法）完全填充牙间区域。结果，所有三例中的黑色三角区均成功转变为自然粉红色三角区。
