Dental radiography is a picture of the teeth and jaws, obtained by exposure to X-ray dental radiographs, dental essential element of diagnosis are performed in order to identify certain details undetectable examination, caries early stages, cysts and granulomas, fractures of the teeth, jaw fractures, tumors, teeth included.
This dentist labor therefore lead to more accurate diagnosis and also help your doctor determine treatment success in all phases of work.
The most used type of dental radiograph is called radiography retroalveolar and is a small film, that can be viewed items 2-3 teeth. X-ray result is issued on the spot within minutes.
Contrary to popular belief less knowledgeable patients, dental radiography shows no health risks. The patient must understand the limitation imposed by the lack of X-rays and that the benefits of information obtained through X-ray, far outweigh the risk given exposure to a minimum dose of ionizing radiation.
Today, many offices have purchased new equipment, performance, equipped with several filter systems X. Using modern techniques of radiation decreases the risk of dental radiographs to near zero. Safe current amount of X-ray examinations received from a very small, and the risk is negligible.
Dental radiography shows a much lower risk than an unidentified and untreated dental problem. Radiation dose received during dental radiography is measured in “rem” or units “sievert”.
Currently, we exhibit the daily radiation from various natural sources (atmospheric, cosmic, terrestrial) as well as artificial sources (microwave, TV, monitor, mobile phone, and so on). However the amount of radiation is much, much higher than that received when performing one or more dental radiographs, whether digital or film.
Of all the X-ray investigations, dental radiography is the least radiation emitted radiation dose of only 0.02 mSv. Here is a simple comparison, but very relevant:
dental radiography – 0.02 mSv
radiation in the environment (natural sources) – 3 mSv / year
Maximum permissible dose is 20 mSv / year.
Additional premium and the amount of radiation from artificial sources, but we can not calculate the overall study because the amount varies depending on our lifestyle – time spent in front of the monitor, cell phone, etc..
Special attention should be given to pregnant and lactating mothers. It is important to remember that dental x-rays do not affect embryo organogenesis and birth process. Radiation from dental X-ray machines, as mentioned before, are very small, targeted towards the teeth and their reflection towards areas considered at risk (abdomen, ovaries, breasts) are protected by a lead apron designed. However, as an additional precaution, it is advisable to avoid as much as possible carrying radiography during the first and last trimester.
To note that in dental radiology centers lead apron (apron especially for protection), provided with a collar to protect the thyroid gland, is used without exception.
