Diagnosis prior to RCT should always be based on:
a- Good medical and dental history.
b- Proper clinical examination.
c- Result of pulp vitality test.
d- A periapical radiographs.
e- All of the above. ***
--------------------------
A periapical radiograph is part of the so-called intraoral radiographs, that is, those that are performed by placing radiological plates of different sizes inside the mouth, in order to obtain complete images of one or two teeth and study it in its entirety: apex, crown, root, bone tissue and periodontal space.
Two different techniques can be used to perform periapical radiography: bisection and parallelism, depending on how the plaque is placed and the angle of incidence on it of the beam of rays.
In any of the cases it is essential that the patient keep the musculature of the mouth very relegated, in order to avoid moving the plaque and it is necessary to repeat it by obtaining a blurred image.
The patient should not be surprised that at the time of having a periapical x-ray, the dentist or nurse asks him or her to hold the plaque.
This does not mean that the patient receives more radiation, but it does protect technicians from accumulating ionizing radiation from their body.
Most of what happens in our human body cannot be seen with the naked eye. For this reason, thanks to X-rays, what happens within our body can be observed.
In dentistry there are several radiographic techniques to perform a good oral study, periapical radiography is one of them.
Periapical radiography is an intraoral radiographic exploratory technique.
Its objective is to see the dental apices, the tip of the roots, and the area around them, hence its peri (around) and apical (apex) name.
Therefore, thanks to it, the entire tooth and its surroundings can be fully explored.
HOW IS THIS RADIOGRAPHIC TECHNIQUE PERFORMED?
This type of radiographic technique is performed using small radiographic plates.
These are placed inside the mouth and are impressed through an external x-ray device.
In the past these radiographs had to be revealed in order to obtain the desired image.
At present, there are intraoral devices that have sensors which allow to generate a digital image and be seen directly on the screen.
This advance has facilitated the entire radiological process and makes it much faster.
Sometimes, to facilitate the realization of this radiographic technique, some devices are used that help to make the radiography look better, the positioners.
These position the x-ray so that all tissues are well distinguished.
WHEN IS A PERIAPICAL RADIOGRAPHY PERFORMED?
Periapical intraoral radiographs are performed to observe and analyze the entire tooth, including the crown of the teeth, its root, the apex, the surrounding bone tissue and the periodontal space, to diagnose possible lesions that are not visible to the naked eye. .
In many cases, a general panoramic radiograph is enough to diagnose and detect any oral anomaly.
Although sometimes, it is necessary to perform periapical radiographs.
These radiographs are usually done to:
- Observe periodontal effects.
We can see if there is bone loss, periodontal pockets and calculus between the teeth and under the gums.
- Guide the periodontal treatment, known the above.
- Verify the endodontic treatment process, both before, during and after its completion.
- Detect periapical lesions, around the tooth. Like periapical cysts.
- Diagnose dental caries, so that they can be classified as they affect the enamel (the most superficial layer), the dentin or have already reached the pulp (the dental nerve).
In this way, interproximal incipient caries are also detected preventively, between the teeth, which are not seen in a simple clinical inspection.
Periapical radiography is a very good radiographic technique in the oral field.
