INTELIHEALTH - Children who have survived cancer may have more problems with cavities. Their teeth also may not form properly.
A study from Turkey compared 96 childhood cancer survivors with 96 healthy children. The average age of the cancer survivors was 11 years. Children who had survived cancer had more cavities. They also had more cavity-causing bacteria in their mouths.
Childhood cancer survivors also were more likely to have teeth that were not formed properly. Dentists call these problems "developmental defects." The most common problem was white or cream-colored spots on the teeth. About 7 of every 10 developmental defects had to do with these spots.
Children who had cancer also were more likely to have tooth roots that were shorter than normal.
Other studies have shown that children who survive cancer are at higher risk for dental problems. The risk may be highest in children whose teeth are still being formed under the gums when they have cancer. Radiation therapy aimed at the jaw can affect this tooth development. It can lead to small teeth, short roots, poor enamel or even missing teeth.
Any cancer treatment that damages the salivary glands also can affect the mouth. If these glands are damaged, there is less saliva in the mouth. That increases cavity risk.
The study appears in the December issue of Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology and Endodontics.
