Left submandibular sialogram showed obstruction of the left submandibular duct by a radiopaque calculus approximately 3 cm proximal to the orifice of the duct [Figure 1a]. The calculus was removed via intraoral approach under local anesthesia [Figure 1b] and transposition of ductal opening was done. The shape of calculus was unusually similar to the canine tooth [Figure 1c].

On orthopantomogram and occlusal radiograph large radiopaque mass is detected of size approximately 20 mm x 6 mm located within the right Wharton's duct [Figures 2a and b]. The unusually large size of calculus was measured to be 19 mm x 5 mm [Figure 2c].
