A 5-year-old girl referred to a clinic for treatment of dental caries. Then, her floor of the mouth was injured by dental air turbine burr. A swelling after suturing of the wound appeared at the injured site 2 days later. After 1 month, a ranula appeared at the area beyond the opposite site across midline of the mouth. Then, a wire probe for diagnosis was inserted in her Warton's canal, and then it was broken. In a salivary gland, a 13×3mm sialolithiasis on the surface of the wire was formed 8 years later. Etiologies of both ranula and sialolithiasis which occurred in the same patient were disccussed in this paper.
