Impacted "Reversed" Fused Tooth: A Case Report
“逆轉型”融合牙：病例報告
摘要
四十歲、男性、中國人，於民國七十五年一月來高雄醫學院附設中和紀念醫院牙科門診，作例行口腔檢查。口內X光小片檢查，發現在下顎左側水平理伏齒牙根分叉處，有一似牙齒構造之放射不透性質塊，經由瓣膜翻開術取出一完整的埋伏齒，臨床及X光檢查無法診斷此異形齒是否為逆轉型融合齒或者為發生於牙根尖分叉處之牙釉珠。經由組織切片檢查，證實為一“逆轉型”融合牙。回顧文獻尚無此異形牙齒之病例報告，故提此此極其罕見的病例以供參考。

A 41-year-old Chinese male was seen for routine dental examination at the dental clinic of Kaohsiung Medical College in February, 1986. An intraoral periapical radiography showed a radiopaque mass at the furcation area of the impacted mabdibular left third molar. The impacted tooth was extracted under local anesthesia and the operative course was uneventful. The histopathological study revealed the final diagnosis of rare phenomenon of “reversed” fused tooth. We found that it was hard to make a definite diagnosis as to whether it is a fusion of the mandibular third molar with a reversed distomolar or an odontoma without histomorphological examination.
