Fusions of teeth and talon cusp are two rare developmental dental anomalies, affecting both primary and permanent dentitions. Both the anomalies are mostly reported as isolated finding and are rarely associated with other dental anomalies. Talon cusp is more common in maxillary anterior teeth in permanent dentition and fusion is commonly reported in mandibular teeth in primary dentition. The co...

Partial pulmonary valvectomy was performed in 19 dogs. No change in pulmonary arterial pulse pressure was seen when less than one valvular cusp was removed; frequently no change was observed when an entire cusp was removed. Widening of the pulmonary arterial pulse pressure could be produced by removal of more than one cusp or by inducing pulmonary hypertension after removal of only one cusp. Ob...

In about half of all near-cusp events in superconducting cosmic strings with chiral currents (and probably with general currents as well), the string intersects itself near the cusp. Intercommutation causes the conversion of the string near the cusp into a vorton (in the chiral case) with very high Lorentz boost. We demonstrate how to analyze the cusp shape in a Lorentz frame that makes the mot...

A horospherical torus about a cusp of a hyperbolic manifold inherits a Euclidean similarity structure, called a cusp shape. We bound the change in cusp shape when the hyperbolic structure of the manifold is deformed via cone deformation preserving the cusp. The bounds are in terms of the change in structure in a neighborhood of the singular locus alone. We then apply this result to provide info...

Let M be a geometrically finite pinched negatively curved Riemannian manifold with at least one cusp. Inspired by the theory of diophantine approximation of a real (or complex) number by rational ones, we develop a theory of approximation of geodesic lines starting from a given cusp by ones returning to it. We define a new invariant for M , the Hurwitz constant of M . It measures how well all g...

The width of the cusp region is an indicator of the strength of the merging process and the degree of opening of the magnetosphere. During three years, the Magion-4 satellite, as part of the Interball project, has collected a unique data set of cusp-like plasma observations in middle and high altitudes. For a comparison of highand low-altitude cusp determination, we map our observations of cusp...

The magnetospheric cusp is a funnel-shaped region where shocked solar wind plasma is able to enter the high-latitude magnetosphere via the process of magnetic reconnection. The plasma observations include various cusp signatures such as ion energy dispersions and diamagnetic effects. We present an overview analysis of cusp plasma observations at the Saturnian magnetosphere from the Cassini spac...

The talon cusp is a relatively rare dental developmental anomaly characterized by cusp-like projections, usually observed on the lingual surface of the affected tooth. Normal enamel covers the cusp and fuses with the lingual aspect of the tooth. The cusp may or may not contain an extension of the pulp. The condition can occur in both the primary and permanent dentitions. However, the occurrence...

dental anomalies are rare findings that may affect development of occlusion and early intervention may be required. here, a case of multiple anomalies in primary and perma nent dentitions is reported. the patient referred to the dental center with the chief complaint of multiple tooth decay. in the oral examination, the rare case of triplica tion between the right geminated man-dibular a and ri...
