The supernumerary tooth was fused with the partially impacted mandibular left third molar horizontally with distinct crown, which was pushing the roots of the third molar, but separated with a radiolucent line in few areas [Figure 1].

Examination of the gross specimen showed that the supernumerary tooth was horizontally fused with the third molar [Figure 2a] and when viewed apically the enamel of the supernumerary tooth was clearly seen [Figure 2b].

The dentin was continuous of both the impacted third molar and the horizontal supernumerary tooth in one area and confirmed the diagnosis of fusion [Figure 4].
