 note = {application/pdf, A case of a fused tooth, involving the left maxillary third molar and the supernumerary tooth, found in a 22-year-old male patient was examined. This supernumerary tooth had 6 cusps and one root. Its root was fused with the root of the third molar on the distal side. 3 DX^[○!R] images and Soft X-ray photographs indicated that both the third molar and the supernumerary tooth also partially shared the same cavity. This fused supernumerary tooth was identified as the distomolar, the so-called fourth molar.},
