2. Panoramic film: You can see the overall situation of the whole oral teeth (the shape and position of the teeth and the situation in the jaw).
3. Dental CT: The jaw and teeth are scanned by computer tomography technology, and the collected data are reconstructed into three-dimensional structures, which truly reproduce the internal combination of jaw and teeth and the adjacent relationship between various tissue structures from multiple angles.
■ What is the radiation amount of various X-rays?
This is a problem that many Ma Ma are concerned about. In fact, we live in radiation all the time, 75% of which comes from nature and 25% from artificial radiation. According to the information provided by the International Commission on Radiation Protection (ICRP), a person receives about 2.5 millisieverts (that is, 2,500 microsieverts), 4-5 microsieverts for small teeth, 7 microsieverts for panoramic films and 100 microsieverts for dental CT.
It is necessary to take dental film for patients who are ready to get pregnant. It is recommended to take dental tablets after 6 months to prepare for pregnancy. For pregnant patients, it is necessary to take dental films, and it is not recommended to take them in the first three months of pregnancy. After all, the fetus is more sensitive than ordinary people. After 3 months, pregnant women should wear protective clothing-lead clothing or a "lead rubber apron" around their abdomen to prevent radiation damage to pregnant women and fetuses. In this case, the impact on the fetus is almost negligible.
Therefore, expectant mothers need not worry too much. As long as protective measures are taken scientifically within a reasonable time, it will not cause harm to the baby. I also want to remind all expectant mothers that they must pay attention to oral health during pregnancy and try to avoid taking dental tablets!
