Advantages and disadvantages of x-rays
Don’t take our word for it - see why 10 million students trust us with their essay needs.
Apart of becoming a new patient at a dental office is taking an x-ray and some may have question along with taking an x-ray, like “will I be affected by the x-ray?” or “will I get cancer?”, “how long will it take” “are x-ray’s safe?”, the list goes on and on. So in this paper we will talk about different types of radiation affects such as affects on children and pregnant women as well as some things that may help reduce some of the radiation that may harm the human body.
In dentistry there is a need for taking an x-ray, the x-ray is a way to help the dentist diagnose a patients oral hygiene and to see if there are any other areas in the mouth that may need to have any type of work. The dentist or the assistant will want to make sure that they can get all the teeth

Even though using a digital radiograph has its benefit it can also increase the dosage to a patient if the image quality is too high. You can try to avoid unnecessary exposure to a patient by making sure that x-rays are taking in the amount of time that is necessary each year and by taking them accurately. Making a routine habit of taking an x-ray may not be the best because every patients mouth is not the same as the last, you will want to treat every patient differently. “A full series of 18 dental x-rays has 27 times less radiation than a lower gastrointestinal series and 20 times less radiation that one year of normal background radiation from the environment.”
When radiation dose is mentioned often wonder what does that mean, well a radiation dose is just how much energy is being taken into the human body when taking an x-ray. The amount of energy that can be taken into the body can become dangerous and damaging to a person causing life time effects such as liver cancer or maybe even a
They could also cause absolute devastating life long injuries, like a limp, cane, crutches or permanent devastating brain damage.
Since the beginning of the propitious world, the core aspect that keeps it thriving is the propensity for people to discover innovations; however, progress of the past is, systematically, detrimental to the future. Not long after the revolutionary invention of the X-ray in the late 19th Century, an unprecedented number of medical examiners noticed (unknown to the time) radiation burns all over their body; decades later, an extraordinary surge in cancer cases had arisen. Perhaps, during the course of these years, scientists and researchers desired to further progress the x-ray (into the immense subsidiaries that are here today), and disregarded any flaws in the apparatus. This systematic inclination continues into the present time as Gary Marshall and Shane Keene notes in their 2007 article, “New technologies allow for patients to be overexposed routinely, and also allow for repeats to be taken quickly, making it easier for a technologist to multiply the patients dose without considering the implications” (5). The gaffes of radiology are present not only in the diagnostic setting, but also in the surgical and therapeutic areas. Working with radiation, it is imperative that the staff is aware of mistakes that are potentially fatal not only for patients, but themselves. It is especially important for medical radiologists to be cognizant of pediatric patients. The standard practice of pediatric radiology in the United States is to follow the step-by step formula from which adult patients are treated and diagnosed. There are copious consequences for following this technique since a child naturally has less body mass and a weaker immune and lymphatic system to manage radiation and its adverse effects. Medical radiology, being a...
...atment is safe because radio-iodine is able to deliver a sufficient amount of radiation to the thyroid allowing to slow the hormone production, and only deliver a small amount to the body. The radiation delivered to the body is far from harmful and is only equivalent to the amount of radiation delivered from two routine diagnostic X-Ray procedures such as a gastrointestinal series ("Educational Material"). The form of treatment has been used for 35 years and over one million patients in the United States have been assisted through the treatment of radioactive iodine ablation. Most physicians will rely on this treatment and recommend 90 percent of their over active thyroid patients to receive the radioactive iodine ("Educational Material"). The treatment, till this day, is known to continuously alleviate the majority of symptoms hyperthyroidism patients have today.
Bitewing radiographs are an important adjunct to clinical examination and maybe necessary to help the clinician detect and diagnose caries (REF). However ionising radiation from x-ray exposure has the potential to cause malignancy in the patient and therefore clin...
For decades, the effects of radiation has been studied by doctors around the world. X-rays are used in the medical and dental field to take radiographs of certain parts of a person's body. Some have become concerned of the long term and short term effects of having x-rays taken because of the radiation that is exposed. Since the rise of concern, studies have been done to find any type of link between cancer and radiation from x-rays. Specifically, in dental x-rays, researchers have been performing studies trying to prove that radiation from x-rays in the dental office can cause cancer .
Computed tomography (CT) and Radionuclide imaging (RNI) are both a form of diagnostic imaging. Since they have been first introduced in medical imaging they both suffered a huge development over the years in terms of image acquisition and also patient radiation protection. The following essay it is going to focus on just a few important things that make CT and RNI similar and different in the same time. However this subject can be discussed in much depth, the focus is going to be on the similarities and differences of the physics imaging methods and also a small awareness of biological effects and radiation protection.
of the usage of radiation and effects it can cause an unborn foetus. A standard pregnancy check, if not worked right and asked correctly could imply stereotyping and thus cause great offence to the patient and/ or their family. Radiographers need to ensure that they justify to the patient (and in some cases family) why they are asking for the pregnancy check. For example instead of asking ‘are you pregnant?’ or ‘could you be pregnant?’ radiographers should instead ask ‘because this examination involves the usage of radiation, is there any chance that you could be pregnant?’
Radiation therapists work closely with patients to fight cancer. According to Health Care Careers, Oncologists, Dosimetrists and nurses are some of the professionals that a radiation therapist works with while caring for a cancer patient. This group of professionals will determine a specialized treatment plan. The first step usually includes a CT scan performed by a radiologist to find the exact area that needs to be targeted with x-rays. Next, the therapist uses a special machine that emits radiation called a Linear Accelerator. They use this machine during a treatment called external beam therapy. During this process, the Linear Accelerator will project x-rays at targeted cancer cells or tumors. Another therapist will be in a different room monitoring the patient’s viral signs until the procedure is over. The external therapy l...
Many of the experts agree that the dose should be kept as low as possible with minimal exposure to the fetus of any age. It has been shown that fetuses before 16 weeks are the most sensitive to any dose of ionizing radiation and have been shown to have lower IQ’s and verbal scores than those exposed after 16 weeks. Fetuses exposed after 16 weeks have the same amount of risk as children up to 10 years old getting cancer. It is very important to take in to consideration gestational age, shielding, the position of the x-ray tube and the amount of necessity that is considered in taking a radiographic image or performing a radiographic procedure in a pregnant woman.
In Dentistry, Radiography (the making of radiographs by exposing an image receptor) is very common. “Radiographs and other imaging modalities are used to diagnose and monitor oral diseases, as well as monitor dentofacial development and the progress or prognosis of therapy.” (Association, 2012). Even though radiation exposure from the dental radiographs is low, the patients and the ADA (American Dental Association) believes that there are some safety tips that must be followed in order for the patient to feel comfortable with getting the radiograph every six months to a year. Modern x-ray equipment is programmed to reduce the amount of radiation. X-rays in dentistry can be performed by using digital imaging or conventional film. Digital imaging continues to develop and is being more commonly used. In this paper I am going to explain how x-rays have became safer over time, what steps dental assistants use to prevent exposure on the patient as well as the office staff, and some safety tips.
...why does the technologist step behind a shield to prevent exposure to themself?" The radiation dose for each exam is relatively small, but over time, the dose can add up. There are many state and federal regulations limiting the total radiation dose that may be received by people working with radiation. To comply with those regulations, the technologist must follow strict precautions to keep their cumulative exposure to a minimum.
DNA damage is a proven biomarker of radiation effects. Cytogenetic techniques commonly employed for detecting DNA strand breakages include chromosome aberrations, micronucleus and comet assay under field and laboratory circumstances. In recent times, flow cytometry (FCM) has been widely used to quantify DNA damage since it offers the analysis of a high number of nuclei in a few minutes providing statistically reliable results in a short period of time. Ideally, all cells within an organism contain the same amount of DNA. DNA damage results from the breakage and rearrangement of chromosomes and from interference with the normal segregation of chromosome during cell division. Double strand breaks are the most important DNA lesions caused by ionizing radiation and other damages from exposure to genotoxic agents resulting in cells with an abnormally high or low DNA content. This variability can be detected as an increased coefficient of variation (CV) of cells in G0/G1 phase as measured by flow cytometry.
dangerous for the body, and can many times lead to being very ill or death.
The energy in ionizing radiation can cause chemical changes in the the cells that can lead to damaging them. Most of the cells can either permanently or temporarily become abnormal or they can just die. Radiation can cause cancer by damaging the DNA in the body. The damage of the cells can also depend on how long the organs are exposed (environmental protection agency, 2017, unknown). If someone has many exposures at one time that radiation in the body keeps adding on. As well as if its only a little bit of exposure in on day and years later you get exposed again it keeps adding on the radiation will never leave the body. Having radiation in your body doesn’t affect you right away but as you get older it starts to show and you feel it. Chronic exposure is when someone is exposed many time for long periods. When this happens the type of effects it will carry is having harmful generic change, cancer, tumors, and even cataracts. Partial health effects can also depend on if it was internal or external exposure. Internal exposure is when either by drinking, breathing, eating and even an injection cause radiation to get inside your body. External exposure is when taking an x-ray out of your body and letting it go through letting all the energy go as it goes in (environmental protection agency, 2017, unknown). In the dental world radiation gets into the patients when we take x-rays on there teeth. In order to avoid to much radiation on them we put a lead apron on them and make sure to cover their thyroid which is the most common way of getting cancer when taking an x-ray. When we take the x-ray we stand behind a wall at least 6 feet away to avoid ourself from getting
