The procedure of taking a panoramic dental X-ray (OPG) may frighten those who are not yet familiar with it, although for some people it is extremely necessary. What is an OPG, how can a panoramic dental X-ray be used to examine not only the teeth but also other tissues, and why does a panoramic X-ray provide much more than several individual X-rays and is much more convenient?
Let us consider what the essence of the procedure is, its strengths and weaknesses, who it is suitable for and who, on the contrary, it is not suitable for, and also determine why it is important.
What Is the Essence of the Panoramic Dental X-Ray Procedure?
During a panoramic dental X-ray, a very small dose of radiation and special equipment can be used to record the condition of the entire oral area. This procedure is performed very often and is an indispensable tool in dentistry.
Moreover, this procedure does not require serious preparation from the patient. The most important thing the doctor needs to know — and this must обязательно be reported — is a possible pregnancy of the patient. So, what is a panoramic dental X-ray?
A panoramic dental X-ray (orthopantomogram) is a type of X-ray image of all the teeth of both jaws, which allows for a general overview of the condition of the entire oral cavity. In addition to the image of the teeth themselves of the upper and lower jaws, an OPG also covers the surrounding tissues and structures.
Among other applications, a panoramic dental X-ray is used in medicine to perform a comprehensive examination of the entire structure of the oral cavity and face without the need to use many separate X-ray images.
How Is a Panoramic Dental X-Ray Taken?
First, the patient is positioned in front of the machine, which rotates the X-ray source around the head. The dental X-ray is taken within a few seconds, during which X-rays pass through the jaws and structures of the head, recording the image on an electronic sensor.
In this way, an image of both jaws of good quality can be obtained, providing information about almost the entire oral cavity. This greatly simplifies the process of taking an X-ray and provides an understanding of many possible problems of the oral cavity at once.
What Is the OPG Algorithm?
In general, the procedure for performing an OPG can be outlined as follows:
- Preparation. Before the procedure, the patient is asked to remove all metal objects, including jewelry, glasses, piercings, etc., after which the head is positioned in a special device for fixing the head and jaws.
- Positioning of the Head and Jaws. The next stage is the necessary fixation: the patient’s head is held in a certain position, and the jaws are positioned so as to obtain the best and clearest possible image.
- Equipment Setup. The equipment must be adjusted: the medical professional prepares the equipment for performing the OPG, determines the radiation parameters, and makes other necessary adjustments.
- Patient Instructions. In order for the panoramic image of the jaw to be as high-quality as possible, the patient is instructed on how to hold their head and jaws.
- Image Evaluation. After the procedure is completed, the medical specialist analyzes the obtained image and evaluates the condition of the teeth, jaws, and adjacent structures.
- Conclusions. The dentist or radiologist makes a conclusion based on the obtained OPG and communicates the results to the patient.
It is important to note that an OPG is a painless procedure and takes only a few minutes. It is an important tool for diagnosis and treatment planning in the field of dentistry and maxillofacial surgery. Taking a dental X-ray in this way is much easier and safer than doing so through several procedures.
What Equipment Is Used?
For performing orthopantomography (OPG), special machines called orthopantomographs or panoramic X-ray machines are used. These machines are specifically designed to obtain a panoramic image of the entire maxillofacial area.
Strengths and Weaknesses of the Procedure
A panoramic dental X-ray is indeed extremely important from a medical point of view. However, this procedure also has its own strengths and weaknesses:
Strengths of the Orthopantomography (OPG) Procedure:
An OPG provides a complete panoramic view of the entire maxillofacial area, including the upper and lower jaws, teeth, joints, and surrounding tissues. The procedure is quick and convenient, usually taking only a few minutes to obtain a three-dimensional image. OPG uses less radiation compared with other X-ray methods, which makes it safer for patients.
The image obtained using an OPG has a high level of detail, allowing the doctor to examine the condition of the teeth and jaws in detail. OPG is also an indispensable tool for diagnosing various dental problems and planning treatment and surgical interventions.
Weaknesses of the Orthopantomography (OPG) Procedure:
An OPG is not always ideal for detailed examination of individual teeth, especially those located close to one another. It may also not provide enough information about soft tissues compared with other methods, such as CT or MRI. Some bone defects or diseases may be less visible on OPG images compared with more high-tech methods.
Proper patient preparation is important for obtaining a high-quality image, including correct positioning and removal of metal objects. OPG equipment can be expensive, and its use also requires a certain level of technical qualification. Taking these factors into account, doctors choose OPG or other methods depending on the specific diagnostic and treatment needs of each patient.
Can an OPG Procedure Be Performed on Children?
Yes, orthopantomography (OPG) can be performed on children, but it is usually used with caution and when necessary, taking into account the characteristics of the child’s age and the physiology of the child’s body.
OPG uses significantly less radiation compared with other X-ray methods, but despite this, questions may arise regarding the effect of radiation on the child’s body. Taking this into account, doctors may decide when to perform OPG on children, considering the need for diagnosis and the potential benefit compared with the risks.
Conclusions
OPG is used to detect a whole range of dental problems, including caries, gum diseases, jaw pathologies, and other conditions. This is a relatively simple and sufficiently advanced way to perform a comprehensive examination of the oral cavity and its tissues and structures.
This method makes it possible to perform a comprehensive examination of the entire structure of the oral cavity and face without the need to use many separate X-ray images.
