A talon cusp is a rare form of developmental anomaly characterized by a well-delineated additional cusp like projection located on the surface of an anterior tooth and extends at least half the distance from the cementoenamel junction to the incisal edge. It usually occurs on palatal and lingual surface of the anterior teeth. On rare occasions the cusp may project from the facial surface or fro...

Hypomelanosis of Ito (HI) is a rare neurocutaneous disorder most likely caused by chromosomal mosaicism. HI patients may suffer from numerous clinical manifestations, but the expression of the disease is highly variable. Ophthalmologic, musculoskeletal, neurologic, and dental anomalies may be associated with the syndrome. The dental abnormalities found in HI include talon cusps, a single maxill...

To assess management of non-syndromic dens evaginatus affecting permanent maxillary central incisor, we performed a systematic review and also present a case report. We searched PubMed via MEDLINE and the reference lists of included reports. Eligible studies were any type of clinical studies describing the management of non-syndromic dens evaginatus affecting the crown of a permanent maxillary ...

The teeth are formed during intrauterine life (i.e., gestation) during the odontogenesis stage. During this period, the teeth move until they enter the oral cavity. This course covers various stages of dental development, namely, initiation, proliferation, histodifferentiation, morphodifferentiation, and apposition. The talon cusp is an anomaly that occurs during morphodifferentiation, and this...

Examination of bald eagles (Haliaeetus leucocephalus) collected from several locations in North America contributed new information concerning the acanthocephalan fauna of this host. Representatives of Arythmorhynchus brevis, representing a new host record, were collected from eagles in Florida, New Hampshire, and Wisconsin. Plagiorhynchus sp. was collected from an eagle in Florida. Corynosoma ...

Renewable energy production is expanding rapidly despite mostly unknown environmental effects on wildlife and habitats. We used genetic and stable isotope data collected from Golden Eagles (Aquila chrysaetos) killed at the Altamont Pass Wind Resource Area (APWRA) in California in demographic models to test hypotheses about the geographic extent and demographic consequences of fatalities caused ...

We analyzed counts from the annual Midwinter Bald Eagle Survey to examine state, regional, and national trends in counts of wintering Bald Eagles (Haliaeetusleucocephalus) within the conterminous 48 United States from 1986 to 2010. Using hierarchical mixed model methods, we report trends in counts from 11,729 surveys along 844 routes in 44 states. Nationwide Bald Eagle counts increased 0.6% per...

Talon cusp (TC) and dens invaginatus (DI) are relatively rare developmental anomalies which affect the shape of teeth. TC is an additional cusp that projects predominately from the lingual surface of anterior teeth. DI is a deep surface invagination of the crown or root which is commonly detected on routine radiographic examination. Both of these anomalies are observed more frequently in perman...

Developmental anomalies affecting number, size, shape, structure, and location of teeth are varied. One such rare anomaly affecting the shape of anterior teeth is talon cusp. It is an accessory cusp-like projection found on lingual or labial surfaces of the upper or lower incisors, unilaterally or bilaterally in both dentitions. It is composed of normal enamel and dentine, with or without pulp....

This paper addresses some of the issues learned during the course of building a written language resource (called ‘Peykare’) for contemporary Persian. After defining five linguistic varieties and 24 different registers based on these linguistic varieties, we collected the texts for Peykare to do a linguistic analysis, including cross-register differences. For tokenization of Persian, we have pr...
