Association between the central papilla and embrasure crown morphology in different gingival biotypes - a
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).

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
Assessment of the Mouth
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...
