The fillings used today are also safer than they used to be. Your dentist will probably use gutta-percha, a resin from the Isonandra Gutta tree found on the Malay Peninsula, to fill the cavity and permanently seal the root canal. Gutta-percha is a rubberlike, waterproof substance that was used to lay the first transatlantic telegraph cable before the invention of plastic.
This manga follows the adventures of Princess Sapphire, a girl who pretends to be a male prince to prevent the evil Duke Duralumin from inheriting the throne of Silverland. It was originally serialized in Kodansha's ShÅjo Club from 1953 to 1956, later collected and released into two tankÅbon volumes.
The most valuable color of Sapphire is a cornflower blue color, known as Kashmir Sapphire or Cornflower Blue Sapphire. Another extremely valuable Sapphire form is the very rare, orange-pink Padparadschah. An exotic type of sapphire, known as Color Changing Sapphire, displays a different color depending on its lighting. In natural light, Color Changing Sapphire is blue, but in artificial light, it is violet. (This effect is the same phenomenon well-known in the gemstone Alexandrite).
