Abstract:

Oral soft tissue has been a highlight topic these days. The morphology of gingival papilla is one of the most important factors influencing esthetics of oral soft tissue. The loss of gingival papilla height leads to black triangle. In anterior region, the black triangle not only results in functional disorder, but also brings in speech problems and esthetic concerns. Researchers from home and abroad reported some morphological factors influencing the height of gingival papilla: Age, gingival biotype, crown form, contact point-crest distance, interdental distance, divergence angle, embrasure morphology, etc. Clinicians must understand the factors that influence the presence of the interproximal papilla in order to prognosis the state of the papilla and to better fulfill the regeneration of lost gingival papilla.

Key words: gingiva, gingival papilla, embrasure, black triangle
