Dental X-rays show important images for timely diagnosis and intervention, follow-up after treatment. In particular, a cephalograph shows a two-dimensional image of the front and back, the structure surrounding the teeth and the skull. Therefore, this is a very important method in orthodontic treatment.
1. What is a cephalometric scan?
Cephalogram, also known as Cephalograph, is a type of X-ray used in dentistry, this method uses X-rays to examine the relationship between the jawbone and the skull. Tilted skull radiographs are used in orthodontic cases such as straightening, orthodontics or braces. Film taking before and after orthodontic treatment helps to evaluate the results before and after treatment for patients.
Usually, in basic orthodontic cases, there is no need for 3D imaging techniques, but just a tilt skull film is enough. Thus, X-ray Cephalo film is very important in orthodontic treatment.
2. What is the role of Cephalo X-ray film?
A cephalometric radiograph can help doctors assess problems such as:
Help classify malocclusion, thereby taking appropriate measures for each type. Assess the condition of the craniofacial structure to choose the right treatment method such as orthodontics, dental implants or surgery. Monitor and evaluate the treatment process to see the changes after correction. Forecasting the development status of the craniofacial system in children, thereby helping to detect and determine the most appropriate time for orthodontic treatment for the baby, limiting tooth extraction as well as jaw surgery in case of craniofacial system has passed the development stage. Provide another look at the temporomandibular joint, assess the issues here. Diagnosing the causes leading to malocclusion such as missing teeth, extra teeth, stiff teeth, convex deformity, cleft palate.

3. Notes when taking Cephalo
This is a method that uses X-rays to survey, so it is likely to cause radioactive contamination and affect health if exposed to a lot. However, the use of X-rays to take X-rays in the medical industry in general and in dentistry in particular is very small, with a short exposure time and well controlled to limit risks. Therefore, most dental X-rays are not dangerous. However, there are a few things to keep in mind when taking Cephalo films:
Remove items that affect image quality such as earrings, removable dentures, hearing aids... Shooting time is very fast, so try Maintain the correct posture according to the instructions for the best image. Before taking an X-ray, tell your doctor if you are pregnant or think you may be pregnant. Dental X-rays are only performed in the mouth area, but there is still a risk of radiation contamination of the fetus. Therefore, the dental X-ray for pregnant women may be delayed so that the radiation does not reach the fetus. If a dental X-ray is absolutely necessary, it needs to be done, then the health care provider will help you limit the risk with fetal protective equipment, such as a lead shirt or lead bib. .. For children, sometimes it is also necessary to have a cephalometric scan to check the child's teething process, avoid misaligned teeth, misaligned bite... To ensure safety, children also need to be protected. Wear lead protectors when taking dental X-rays. To minimize the impact of X-rays on health, you can choose X-ray facilities with digital machines and should not take films too often. Because digital photography uses an electronic sensor instead of X-ray film, it uses less radiation and is safer. Cephalograph is a simple method but brings high value in diagnosis, treatment and post-treatment follow-up. The X-ray film has also been optimized for harmful factors to the body, so there is no need to worry, however, if children or pregnant women still need protective measures to minimize the risk of harm. .
