The purpose of this study is to assess patients' aesthetic perceptions of interdental "black triangles", both in terms of the number of triangles visible and their severity; and to ascertain how patients rank the presence of "black triangles" against other aesthetic problems. It is based on a questionnaire of 80 randomly selected individuals who were asked to rate the aesthetics of digitally-manipulated images. Patients'perceptions of interdental "black triangles" were compared with their perceptions of other 'non-aesthetic' features. Interdental "black triangles" were rated as the third most disliked aesthetic problem below caries and crown margins. This study demonstrates the importance of interdental "black triangles" to patients, and therefore, as they can occur during prosthetic treatment, must be discussed with patients prior to commencing therapy.
本研究的目的是评估患者对牙间“黑三角”的美学认知，包括可见三角的数量及其严重程度；并确定患者如何将“黑三角”的存在与其他美学问题进行排名。该研究基于对80名随机选择的个体进行的问卷调查，这些个体被要求对数字处理后的图像的美观程度进行评分。将患者对牙间“黑三角”的认知与他们对其他“非美学”特征的认知进行比较。牙间“黑三角”被评为仅次于龋齿和牙冠边缘的第三大最不受欢迎的美学问题。本研究证明了牙间“黑三角”对患者的重要性，因此，由于其可能在修复治疗过程中出现，在开始治疗前必须与患者进行讨论。
