Discovery of X-Radiation in Dentistry

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

According to Oxford Dictionaries, an X-ray, also known as a type of radiation is defined as an electromagnetic wave of high energy and very short wavelength (between ultraviolet light and gamma rays), which is able to pass through many materials opaque to light and being absorbed to different degrees by different materials. In medicine, an X-ray is produced by the deceleration of charged particles, especially electrons, or by electron transitions in atoms. An X-ray machine sends these particles through the body. The images are recorded on a computer to produce a radiograph. Structures that are dense will block most of the charged particles and will appear white. A special dye that contains metal or contrast media is used to highlight areas of the body. These areas will also appear white. Structures containing air will be shown as black. Muscle and fat tissues and fluid would be shown as shades of grey.

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...

Radiation Therapy Report What is Radiation Therapy? Radiation Therapy also known as Radiotherapy uses high energy radiation. Radiation is energy which can come from many different sources.

Dr. Loewi dreamed of an experiment that he could perform to validate and prove how nerve impulses are transmitted. He woke up in the middle of the night and while he was still half a sleep he scrawled down some notes from the dream and went back to sleep. But when he woke up, unfortunately the scribbles were peculiar to him and he was unable to understand a single note . Luckily, next day after another dream he was able to remember all the important parts of experiment. This unexpected discovery, what called " Eureka moment" helped Dr. Loewi to come up with a huge scientific discovery to solve one of the complicated medical questions of his time.

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

The assessment of skeletal bones by the use of x-rays can aid in the identification of corpses. Radiographic images of the skeletal remains are taken and are compared to the potential victim’s ante mortem x-ray images in order to deduce a positive identity to the body. The comparison method of skeletal radiography performs similarly to the comparison of dental x-rays to the dental records that the patient had before becoming diseased. The skeletal structure of the bone’s shape, size, and contour can determine an estimation of the victim’s age, sex, height, weight and body build. The pelvis bones are an indicator of the gender in which the female pelvic bones are wide with a pubic arch greater than 90 degrees while the male pelvis bones are

The history of radiology goes back to 1895. It came into existence in 1895 when the discovery of X-rays by William Roentgen revolutionized medicine by making it possible for doctors to see inside the body without cutting it open (“Radiologist”). Because of the invention of Radiography unnecessary surgeries were able to be eliminated. The results of this pioneering work were reported to the Society for Physical Medicine of Wurzburg the following month (Tan). The first two decades after its discovery, radiology was used mainly for diagnosis and treatment of fractures and for localization of foreign bodies, such as men from both World Wars who needed bullets removed. Within a few months of Rontgen’s discovery, attempts were made to make films of moving objects. Later, in the 1950’s, this technique was used again (“Radiology” Britannica). The individuals that knew of Rontgen’s work wanted it to get out to the health indu...

Glow sticks started when scientists tried to replicate the natural bioluminescence, the light emitted by organisms such as fireflies. In the 1960's Edwin Chandross of Bell Labs patented the first glow sticks out of oxalyl chloride and hydrogen peroxide. Building on "Chandross' discovery, a team from the labe called American ?Cynaamid led by Michael M. Rabut created an oxalate ester named pehenyl oxalate to replace the oxaly

The history of 3d imaging started in 1895 when the German physicist Wilhelm Conrad Röntgen reviled the discovery of a new penetrating form of electromagnetic radiation. He realized the potential medical application of his discovery. So he reported his invention to the Physical Medical Society of Würzburg, and he included in his presentation an X-ray image of his wife’s hand.
