Doctors removed a tumor from the lower jaw of a seven-year-old boy, in which there were 526 "teeth", reports The New Indian Express. The patient was diagnosed with odontoma, an anomaly in the development of dental tissue that is asymptomatic, so it is usually found by accident.
An odontoma is a benign tumor consisting of overgrown tissues that develops in the bones of the upper or lower jaw (rarely in both). According to various estimates, odontomas account for 20 to 76 percent of all odontogenic tumors. The reasons for their occurrence are not exactly known, but some researchers associate their occurrence with injury and inflammation at an early age, as well as a genetic predisposition.
The average age of patients who develop such tumors is 14.8 years, but sometimes adults have also come to dentists. Moreover, odontomas develop not only in humans, but also in other mammals, as well as in their synapsid relatives. For example, paleontologists have described an odontoma in a gorgonops who lived 255 million years ago.
Odontomas usually develop asymptomatically, so they are often found by accident, during x-rays or tooth extraction. Such tumors can consist only of dental tissues of one or several types (dentin, enamel, cement), or soft tissues can occur in addition to them. Odontomas can consist of denticles - small abnormal formations similar in structure to teeth. In the scientific literature, there are cases of extraction of 30, 37 and 75 denticles from the odontoma. The press also described a case when doctors from the Indian city of Mumbai removed an odontoma from a 17-year-old boy, which turned out to have 232 teeth. The largest odontoma recorded in humans weighed 300 grams, but how much denticle was in it is unknown.
In July of this year, Indian doctors had to deal with another very large odontoma. A seven-year-old boy was admitted to Savithha Hospital in Chennai with complaints of a growing swelling in his right cheek. Using a panoramic tomography and a computer scan, doctors revealed an odontoma in his right lower jaw. On July 11, the tumor was operated on. According to Professor P. Senthilnathan, the tumor weighed 200 grams and was a sac-like structure full of denticles. During the operation, the surgeons did not need to break the bone, so the boy would not need jaw reconstruction. However, due to a tumor, two molars have not grown in him, so, apparently, he will have to put implants.

There were 526 denticles in the tumor, which "were of various sizes, from 0.1 to 15 millimeters," said the head of the hospital's oral and maxillofacial surgery department, Dr. Prathibha Ramani. "They looked like pearls in an oyster, and even the smallest had a root, crown and enamel."
Earlier, doctors found that people who were prescribed opioids as pain relievers after removing their wisdom teeth were more likely to develop opioid dependence during the next year. Of the more than 14,000 people who visited the dentist and then took opioids, six percent ended up with drug addiction.
