[Application progress in measurement methods for interdental papilla deficiency].

Currently, there is an increasing demand for the treatment and reconstruction of interproximal papilla defects in the anterior aesthetic zone. However, the lack of standardized measurement methods and indicators for assessing anterior interproximal papilla defects undermines the scientific rigor and accuracy of related research, and hampers comparability across studies. Common measurement methods for interproximal papilla defects include direct periodontal probe measurement, intraoral photographic measurement, and intraoral scanning data measurement. The direct periodontal probe method is simple to perform with low accuracy yet. The intraoral photographic method, which involves taking intraoral images and analyzing with image analysis software, is susceptible to variations in shooting environment, parameter settings, and reference markers. The intraoral scanning data method, which combines intraoral scanning with reverse engineering software, offers advantages such as accuracy, reproducibility, and multi-dimensional assessment. However, it is influenced by scanning precision. This article reviews commonly used measurement methods for anterior interproximal papilla defects in recent years, aiming to provide research insights for relevant researchers and clinicians, promote the application of more accurate measurement methods in evaluating the severity of interproximal papilla defects, and ultimately improve the outcomes of papilla reconstruction procedures.
