Double teeth, also called connated or cojoined teeth, are clinically present as two separate teeth united by dentin. It occurs due to the fusion of two individual tooth buds or the partial splitting of one into two. An accessory supernumerary fourth molar is called a distomolar or distodens. Usually, the distomolar has a small crown that can be conical, peg-shaped, or like a small premolar called molariform distomolar that occurs distal to the last molar. This case presents an impacted molariform distomolar with the fusion of crown and root in a 27-year-old female.
双排牙，也称为融合牙或联合牙，临床上表现为两颗由牙本质相连的独立牙齿。它是由于两个独立的牙胚融合或一个牙胚部分分裂成两个而形成的。额外的第四磨牙被称为远中磨牙或远中多生牙。通常，远中磨牙有一个小牙冠，可能呈圆锥形、钉状，或者像一个小前磨牙，称为磨牙形远中磨牙，位于最后一颗磨牙的远中。本病例报告了一名27岁女性患者，其磨牙形远中磨牙阻生，牙冠和牙根融合。
