An independent state in the West Indies. Its capital is Castries. It was probably discovered by Columbus in 1502 and first settled by the English in 1605. Contended for by the French and English in the 17th century, it was regarded as neutral in 1748 but changed hands many times in the wars of the 19th century. It became a self-governing state in association with Great Britain in 1967 and achieved independence in 1979. Columbus named it for the day on which he discovered it, the feast of St. Lucy, a Sicilian virgin martyr. (From Webster's New Geographical Dictionary, 1988, p1051 & Room, Brewer's Dictionary of Names, 1992, p477)

Dental Prosthesis Design
Radiography, Dental, Digital
A rapid, low-dose, digital imaging system using a small intraoral sensor instead of radiographic film, an intensifying screen, and a charge-coupled device. It presents the possibility of reduced patient exposure and minimal distortion, although resolution and latitude are inferior to standard dental radiography. A receiver is placed in the mouth, routing signals to a computer which images the signals on a screen or in print. It includes digitizing from x-ray film or any other detector. (From MEDLINE abstracts; personal communication from Dr. Charles Berthold, NIDR)
