Doctors in India have removed 526 teeth from a 7-year-old boy.

印度醫(yī)生從一名7歲男孩身上摘除了526顆牙齒。

The 7-year-old, named Ravindranath, was taken to Saveetha Dental College in Chennai, India, after he complained of swelling on the right side of his lower jaw.

這名7歲的男孩名叫拉文德拉納特(Ravindranath)，他被送往印度金奈(Chennai)的Saveetha牙科學院(Saveetha Dental College)接受治療，此前他抱怨自己的下頜右側腫脹。

His parents said he had experienced the swelling since he was 3, India's National Herald reported, but the condition had worsened and required immediate medical attention.

據印度《國家先驅報》(National Herald)報道，他的父母說，他從3歲起就開始腫脹，但病情惡化，需要立即就醫(yī)。

An X-ray of the boy's jaw revealed a sack of tissue weighing 200 grams, doctors said. It contained 526 teeth.

醫(yī)生說，男孩下巴的x光片顯示出一袋重達200克的組織。它有526顆牙齒。

The sack was a "compound composite odontoma," a benign tumor made up of normal dental tissue such as enamel, according to CBS News. Such tumors are most commonly found in teenagers.

據哥倫比亞廣播公司新聞報道，這個袋子是一個“復合牙本質瘤”，是由正常的牙釉質等牙齒組織構成的良性腫瘤。這種腫瘤最常見于青少年。

Some were a 10th of a millimeter, while others were up to 15 millimeters, the Times of India reported, but all had the properties of teeth, with a crown and a molar.據《印度時報》(Times of India)報道，其中一些只有0.1毫米，而另一些則高達15毫米，但它們都具有牙齒的特征，有牙冠和臼齒。

The surgery took five hours.

手術花了五個小時。

"It was reminiscent of pearls in an oyster," said the doctors, according to the Herald.

據《先驅報》報道，醫(yī)生們說:“這讓人想起牡蠣中的珍珠。

The cause of the growth remains unclear, though doctors at the college have narrowed down the possibilities to genetics or even radiation from cellphone towers.

這種增長的原因還不清楚，不過該學院的醫(yī)生已經縮小了基因甚至是手機信號塔輻射的可能性。

A similar case took place in 2014, when dentists extracted 232 teeth from a teen in Mumbai.

2014年也發(fā)生過類似的情況，當時牙醫(yī)從孟買的一名青少年身上拔下了232顆牙齒。
