Talon cusp is a rare developmental anomaly that occurs most commonly on the lingual side of the incisors. Occurrence of the labial talon cusp is rare in the dental literature. Till date only seven cases of isolated nonsyndromic labial talon cusps have been reported in the maxillary permanent dentition. However, a few cases of syndromic labial talon cusps and faciolingual talon cusps have been r...

Talon cusp is a rare developmental extra cusp-like projection on the cingulum area of affected anterior teeth that may cause various functional and aesthetic problems. The present report describes a case of bilateral palatal talon cusps on permanent maxillary incisors and the treatment procedure to overcome the clinical problems associated with talon cusps.

Cusp properties during periods of By dominant IMF are investigated, since previous studies focus mostly on IMF Bz. The model-data comparisons for various IMF configurations show that the model captures the large-scale features of the particle precipitation very well, not only in the cusp region, but also in other open-field line regions such as the mantle, polar rain, and openfield line low-alt...

if we accept this idea that in talking about art, there is a chasm between thought and unthought debating on art theory in the sociohistorical context of after revolutionary iran requires at least two items in which understanding and creating art meet one another: 1) art as door separates intelligible from sensible, rational from irrational, and logos from pathos as well and 2) art as bridge no...

tooth fracture is a common dental problem. by extension of cavity dimensions, the remaining tooth structure weakens and occlusal forces may cause tooth fracture. the aim of this study was to evaluate and compare the fracture resistance of teeth restored with direct and indirect composite restorations.sixty-five sound maxillary premolar teeth were chosen and randomly divided into five groups eac...

Enamel prism-packing patterns reflect the past history of ameloblasts, providing information about growth patterns in tooth development. Here, the area and density of enamel prisms on the cuspal surface of molar teeth were measured to examine if the onset and rate of enamel apposition differ according to stage of development and/or cusp type. Scanning electron-microscopic images were taken from...

Abstract. In many applications of practical interest, for example, in control theory, economics, electronics and neural networks, the dynamics of the system under consideration can be modelled by an endomorphism, which is a discrete smooth map that does not have a uniquely defined inverse; one also speaks simply of a noninvertible map. In contrast to the better known case of a dynamical system ...

The Hamiltonian Hopf bifurcation is described by part of a swallowtail surface. In this short note it is shown that this swallowtail is actually a non-transversally unfolded cusp singularity, and that the swallowtail surface is obtained by folding a cusp along a fold line that is tangent to the cusp and moving along the cusp.

OBJECTIVES To determine the frequency, variability, sexual dimorphism and bilateral symmetry of fourteen dental crown traits in the deciduous and permanent dentition of 60 dental models (35 women and 25 men) obtained from a native, indigenous group of Nasa school children of the Musse Ukue group in the municipality of Morales, Department of Cauca, Colombia. METHODS This is a quantitative, des...
