Significance of the Radiographic Film for Dentist


The use of radiography is considered important in diagnosing the hard tissues in the mouth, for example, the bones; however, the role of a dentist is crucial for determining the success of radiography. The skill of a dentist is significant for proper positioning and getting desired results of radiography and oral tissues. This means that the dentist has to take precaution to use radiography for diagnosing the root causes of disease in the mouth. In other words, the quality of radiography is dependent on the quality of radiograph to assess the disease in a proper way, and the use of radiography must be taken with care because it can have harmful effects on the sensitive parts of the mouth.

In terms of the proper use of radiography, the role of a skilled dentist is crucial. For example, it is the dark areas in x-ray, which can determine the soft tissue from the hard tissues. If you change the kV, it changes the density of radiography. When kV decreases, it reduces the density by making it lighter. Similarly, if one increases the kV the darkness of the radiography increases by making it darker. So, it is required for determining the root cause of dental issues, especially if it is not visible with naked eye. Hence, the dentist uses the radiography for diagnosing the internal diseases.

The contrast of radiograph is the level of darkness in the radiograph, in simple words. This helps in indicating the borders of the tissues in the mouth. It is beneficial for over viewing the PDL widening, which is usually not visible if the contrast is light or dark. In terms of sharpness of radiography, the image of x-ray is largely dependent on sharpness for getting an accurate image of the oral tissues. Moreover, the quality of x-ray is required for diagnosing and clearly indicating borders and outlines of teeth. So, the sharpness of radiograph is essential for the getting a clear image of the mouth along with bones.


The foreshortening of image means that the image in x-ray is very small. It happens because of vertical angulations of the x-ray tube while using the radiography. Its use can become tricky in endodontic treatment, where working length is different due to the differences in the size of teeth. Moreover, the elongation of an image implies the image of teeth and surrounding structure of teeth can appear longer than their original size. So, it is difficult for the dentist to get correct length in endodontic treatment and other procedures to diagnose the different diseases and to underline the hidden parts of the mouth.

In some cases, some teeth are longer than the others, which can cause bending of teeth when the x-ray is placed in the mouth of a patient. The area of teeth, which is subject to x-ray, should not bend too much on a bed of teeth. Rather it should be bend gently for a film to capture the image of intra-oral parts and the mouth including palate and floor oral cavity. The chances of x-ray film rolling around premolar areas can increase, because of the contours of the palate in the mouth. So, the best way to avoid is to use it with caution in order to get a clear image of the mouth.

If you have the overlapping proximal, you cannot get the clear image from radiograph because x-ray is impractical. The overlapping occurs because either x-ray is placed too near or too far from the beam of x-ray. Ideally, the occlusal must be parallel to the margin of the x-ray. If it is slanting, then getting the clear image is not possible, because a film is not placed properly in the mouth of the patient. Furthermore, the alignment of x-ray film in the mouth is vital for getting the desired results in form of the clear image of the mouth. In other words, the clarity of the image is required for diagnosing the root cause of the problem.

If the occlusal portion of teeth is not clear or the the placement of x-ray film is not proper while putting it in the mouth of a patient, the visibility of the x-ray between the occlusal and incisal can be balanced with the margin of the x-ray and to record the image clearly. The coronal part of teeth can be recorded in form of x-ray image to get the complete image of the whole teeth. Moreover, the clarity of image in x-ray is essential for the dentists in performing the dental procedure effectively.

The periapical image is usually not clear if radiograph is not used in proper way. The clarity of the image is essential for making the diagnostic useful and effective. If the image is unclear or distorted, it may create confusion for a dentist in diagnosing the root cause which can eventually affect the patient. So, the reason behind blur or distorted image has either to do with the movement by patient or misplacement of x-ray beam while taking the image of your mouth. If the image is a blur, one cannot get the clear image of adjacent structures of the mouth in a better way.

The cone cut image is the clear area in the radiograph. It is more clear than other parts because of the beam of x-ray is not perpendicular to the film of x-ray. The term pial angioma is used for the appearance of fingers image in the x-ray. It happens when the film is not placed in right place and a right angle may create an image of the fingers on the x-ray. When there is exposure, one can hold x-ray with fingers to avoid the disruption of the image taken by radiograph. You can also take help of dentist Eagle Rock for using radiography.  


To conclude, one can say that the use of radiography is beneficial for treating and diagnosing different hidden problems in the mouth. The exposure of light and darker part in x-ray is required for highlighting the different parts of the mouth and for getting the clear image. The placement of x-ray film is vital because if it is bending too much, it will destroy the x-ray.  Therefore, one should be careful with the film placement and its coordination with caution, in addition to getting the desired results. Hence, the ideal method for using radiograph can be achieved if you go to a trained dentist.
