Pioneers/Discovery of X-Radiation in Dentistry In 1895, Professor Wilhelm C. Roentgen, a German physicist, was working with a cathode ray tube, much like our fluorescent light bulb. The tube consisted of positive and negative electrodes encapsulated in a glass envelope. On November 8, 1895, Roentgen was conducting experiments in his lab on the effects of cathode rays. He evacuated all the air from the tube and passed a high electric voltage through it after filling it with a special gas. When he did this, the tube began to give off a fluorescent glow. Roentgen then shielded the tube with heavy black paper and discovered a green colored fluorescent light could be seen coming from a screen located a few feet away from the tube. He had produced an unknown ray being emitted from the tube that could pass through the paper. He found that this new ray would pass through most objects, casting shadows of solid substances. He first investigated with his hand and was surprised when he saw his bones. His discovery would open up an exciting field for doctors because now it was possible to stu...
Wilhelm Roentgen investigated the light phenomena and other emissions created by releasing electrical currents in Crookes tubes, and glass bulbs, evacuated of air, with negative and positive electrodes. When a high voltage current was sent through these bulbs, a fluorescent glow would be displayed in them. During this time, Roentgen was studying electrical ray’s path as they were passing from an induction coil through a glass tube that was partially evacuated. For this experiment, the tube he used was in a completely dark room, and it was covered in black paper. Roentgen noticed that the platinobarium screen, which was nine feet away and covered in fluorescent material, was illuminated. He knew that the screen was illuminating due to the rays.
Due the fact that he was not there to tend to his wife during her dying days, he decided to end his career of painting and tried to develop a technology that could transmit and receive information that was faster than the current methods that were available during th...

At the beginning when Crookes started his studies with the fluorescent light, it was not understood very well, just because of the mysterious rays, which were called “cathode rays” because they were seemed to be produced by the negative electrode. But his experiments, was so helpful to show how the new information was important for the nature of the unknown rays.
In the time when he was studying medicine, he made a very important science discovery that started his career. One day at church service on Sunday he looked up at a lamp and the lamp was swinging on a long cord back and forth. Its swing was very regular and he used his own pulse to measure the sing. He noticed even as the swing grew shorter the amount of time for a single was the same. Later he went home and conducted many experiments with different lengths and weights. Then he concluded that the string length affected the swing. Soon he created the pendulum and used the same principle to make a pulsilogia which is a device that measures your pulse (Hightower 17-20).
It started with the British, with the arc lamp in 1835. For years after people around the world experimented on an incandescent lamp. They tried things like filling the bulb with gas but they did not last very long and they were very expensive. Finally in 1879, Thomas Edison made a bamboo filament (the part of the bulb that actually makes the light) that was able to last 1,200 hours. Lighting has changed over the years but some of the new inventions still were made in the 1800’s. Glassblower Heinrich Geissler and physician Julius Plücker discovered that they could make light by removing almost all of the air from a long glass tube and by passing an electrical current through it. They called it the Geissler tube. In the early 1900’s Peter Cooper Hewitt made the fluorescent lamp. While the Cooper Hewitt lamps were more efficient than incandescent bulbs, no one really used them because of the blue green color of the light. European researchers made neon tubes coated with phosphors (that made the light white). In the mid and late 1930s the U.S. was showing the fluorescent lights to the navy and at the 1939 New York World’s Fair. These lights lasted longer and were about three times more efficient than incandescent bulbs. In 1976, Edward Hammer at General Electric figured out how to bend the fluorescent tube into a spiral shape, creating the first compact fluorescent light
The demonstration of the Incandescent light bulb was held in downtown New York City, New York at financier J.P Morgan’s office. The incandescent light bulb had instantly spread throughout the majority of the American homes and offices. The first incandescent light bulb used a carbon base inside a glass bulb until it became hot to produce a glow, (CITE). Many of the first designs were burning up quickly due to a poor vacuum design. Gas companies once dominated the industry were having a difficult time promoting the arc lamp due to the new invention of the Incandescent light bulb, (CITE). By the year 1892, the distribution of electric power replaced the gas setup, which had formally set up throughout the cities and the majority of the

During the cold winter of 1895, a German scientist by the name of Wilhelm Conrad Roentgen was working with a cathode-ray tube when he noticed nearby crystals were glowing. When Roentgen reached for the crystals he was amazed when the shadow cast on the crystal was not of his whole hand, but just his bones. Roentgen covered the tube with heavy black paper and saw that the crystals still glowed and the shadow of his hand bones still shown through, he then determined that a new ray was being emitted that could penetrate through thick materials. (1.) He later found that the rays could pass through most anything, but would cast a shadow of solid objects; these shadows could then be captured on film. Among the solid objects Roentgen shot with these rays was human tissue, the rays would penetrate the tissue, but the bones would cast a shadow, which could then be caught on film. One of Roentgen’s first experiments with X-rays was on his wife’s hand where, on the film, you could see her hand bones and her wedding ring. (1.) While the discovery of x-rays was a huge advancement in medical technology, they were not used in the medical field at first. Instead the mystical invisible rays that could penetrate solid objects were used in the industrial field.
Another main version of the television was patented in 1929. This was Vladimir K. Zworykin’s kinescope, which was a cathode-ray tube. The storage principle it used is one of the main components of modern-day televisions.
Dentists have been around for thousands of years. Dentistry got its start in the Indus Valley of India And Pakistan. “The earliest history of treating tooth related problems goes all the way back to 7000 BC, where the Indus Valley Civilization shows evidence of treating the mouth for tooth decay. The first method of treatment was bow drills, which were ancient primitive tools used for woodworking and treating tooth problems.” (http://www.todayifoundout.com/index.php/2012/12/the-history-of-dentistry/)paragrah1 .These industrious would be dentists were master bead makers who used bow drills to cure tooth problems. From the ancient Egyptians to the Greco-Romans to early Chinese civilizations dentists have existed to aid the people with their teeth problems.
In the early 17th century, people were unsure about how the body system worked, especially when it came to blood. It wasn’t until the mid-1600’s that William Harvey discovered how the blood circulates throughout the body. Harvey was an English Physician whose discoveries greatly impacted medical science. This discovery completely changed the field of medicine. He first “observed the action of the heart in small animals and fishes” (Weisstein). When observing these small animals he concluded on how the blood circulates the bodies. He made many discoveries in which he announced the way the body works and how it uses blood. “He developed the first complete theory of the circulation of blood, believing that it was pushed throughout the body by the heart’s contractions” (Weisstein). There were still many gaps in the process of how the blood circulates, but...
But In November 8, 1895 a moment that revolutionized the world of Science, Wilhelm Conrad Rontgen had discovered what he called X-rays. He was working in his laboratory operating one of Crooke’s tube which is the main source of cathode rays. The room was dark and when he exposed the rays he noticed that a paper made of barium platinocyanide was glowing. Rontgen try the experiment several times until he concluded that it was a new kind of ray rather than just light or electricity emitting from Crooke’s tube. He also concluded with his experiments that different kind of materials had a different degree of penetration depending on the density of the material. As he continued with his experiments he placed his wife’s hand on a image receptor and exposed the hand with the x-ray. The image was developed and was another proof of the discovery of x-rays when her hand showed the bones along with a ring she was wearing. During this time, Rontgen and his fellow colleagues didn't know about the fatal consequences of radiation. Wilhelm Conrad Roentgen died in Munich, Germany in February 10, 1923. The reason of his death was carcinoma of the intestines. Coincidence, probably
