綜合外媒報道，巴西米納斯吉拉斯州一位女童因計畫鏟除一顆上排乳牙，接管牙科檢查，但是，X光影象揭露驚人發現，她嘴中竟然有18顆乳牙、32顆恆牙，和額外的31顆多生牙，牙齒總數高達81顆。
巴西女童嘴裡「塞滿81顆牙」 X光一照牙醫嚇傻：史上罕有

巴西一位11歲女童去看牙醫，原本只是要拔牙，成績一照X光竟發現口中竟有高達81顆牙齒，令牙醫大感訝異，過後這起超等罕見的案例更被登載在醫學雜誌上，成為熱議的核心。
正常成年人應有32顆牙齒，而額外多長出來的牙齒則被界說為「多生牙」，一般多生牙只會呈現1到2顆，是以像該名巴西女童如斯數目驚人的多生牙極為罕見。
多生牙常深藏牙齦，不只會阻礙正常牙齒生長，致使牙齒排列不齊，乃至激發囊腫等問題。","publisher":{"@type":"Organization","name":"Yahoo奇摩新聞","logo":{"@type":"ImageObject","url":"https://s.yimg.com/cv/apiv2/twmobi/icon/yahoo_tw_logo_structuredata_20200630.png","width":136,"height":60}},"author":{"@type":"Person","name":"陳嘉玲","url":"","jobTitle":""},"creator":{"@type":"Person","name":"陳嘉玲","url":"","jobTitle":""},"provider":{"@type":"Organization","name":"鏡週刊Mirror Media","url":"https://www.mirrormedia.mg/","logo":{"@type":"ImageObject","width":300,"height":131,"url":"https://s.yimg.com/os/creatr-uploaded-images/2020-10/17058a70-0943-11eb-aef6-18fe60719dad"}},"image":{"@type":"ImageObject","url":"https://s.yimg.com/ny/api/res/1.2/NQbZkkvjttmkRVe72pJF8w--/YXBwaWQ9aGlnaGxhbmRlcjt3PTI0MDA7aD0xNTg0/https://media.zenfs.com/ko/mirrormedia.mg/0acca55c152ec607ac768e84fddfbe99","height":792,"width":1200},"thumbnailUrl":"https://s.yimg.com/ny/api/res/1.2/NQbZkkvjttmkRVe72pJF8w--/YXBwaWQ9aGlnaGxhbmRlcjt3PTI0MDA7aD0xNTg0/https://media.zenfs.com/ko/mirrormedia.mg/0acca55c152ec607ac768e84fddfbe99"}
