BACKGROUND: The presence of an interproximal gingival (central) papilla is of prime importance and an essential component of a harmonious and pleasing smile. The aim of this study was to determine the association between the presence of a central papilla and embrasure and crown morphology. METHODS: The study was conducted on 200 periodontally healthy patients. Parameters such a central papilla presence, gingival thickness, crown length, crown width, contact surface, radiographic assessment of bone crest to contact point (BC-CP), and interdental width (IDW) in maxillary central incisor embrasure morphology were recorded. RESULTS: A statistically strong significance (P = 0.001) was found for the presence of a central papilla, which was 100% in squarish crown morphology and reduced for tapered squarish and triangular crown forms. A gingival biotype with a thickness of 1.5 to 2.0 mm exhibited a central papilla presence of 88.46%. All the interdental variables were significantly related to the presence of a central papilla, with BC-CP distance and IDW demonstrating a high significance (P < 0.0001). CONCLUSION: In relation to the maxillary central incisors, the crown and embrasure morphologies have a strong influence over the presence of a central papilla. (Int J Esthet Dent 2016;11:550-563).
