Abstract

 Background: The distance from bone crest to contact point is an important parameter which influences papilla fill. Aim: The aim of this study was to assess the association between embrasure morphology and central papilla recession. Methods: The central papilla was visually assessed in 100 subjects, aged 18-35 years (mean age 27 years) using paralleling periapical radiographs of maxillary central incisors taken with radiographic grids. The following vertical distances were measured: the recession distance, i.e., Papilla Tip to Contact Point (PT–CP), Bone Crest to Contact Point (BC-CP), proximal Cemento Enamel Junction to Contact Point (pCEJ–CP), Bone Crest to Papilla Tip (BC-PT), and Bone Crest to proximal CEJ (BC–pCEJ). Interdental width (IW) was measured horizontally and Crown Width (CW) was also assessed using a software tool ( Klonk Image Measurement tool). Results: Age, papilla recession status, PT–CP, BC–pCEJ, CW, PT–CP, IW, BCCP were independent predictors of Clinically Observed Papilla Height (COPH). Conclusion: Gingival papillary height was significantly associated with BC-CP, IW and age in the present study. These factors should thus be considered while treating papilla recession cases.
