Assessment of the thickness of gingival tissues using the probe visibility test is regarded as the method of choice during routine examinations. However, the probe visibility test has not been validated for patients with gingival pigmentation and its accuracy in populations with physiological gingival pigmentation is yet unknown. This study aims to evaluate different methods for the clinical assessment of gingival thickness in participants with varying levels of gingival pigmentation.

评估不同牙龈色素沉着水平的多民族受试者的牙龈厚度

使用探针可见性测试评估牙龈组织厚度被认为是常规检查中的首选方法。然而，探针可见性测试尚未针对牙龈色素沉着患者进行验证，其在生理性牙龈色素沉着人群中的准确性尚不清楚。本研究旨在评估临床评估不同牙龈色素沉着水平参与者牙龈厚度的不同方法。
