Inflammatory odontogenic cysts are benign osteolytic asymptomatic lesions and can destroy the surrounding bone and let it infected. The term residual cyst is used most often for retained radicular cyst from teeth that has been removed. Residual cysts are among most common cysts of the jaws. It can be concluded that early detection and accurate diagnosis are essential for the proper treatment of the residual cysts. This case report reveals some of the technical considerations in managing huge maxillary midline residual cyst surgically.

Accidental displacement of an impacted third molar, either a crown, root piece, or the entire tooth, is a rare complication that occurs during surgical removal. The most common sites of dislodgment of an impacted mandibular third molar root are the submandibular, sublingual and pterygomandibular spaces. Removal of a displaced root from these spaces may be complex due to poor visualization and limited access. A thorough evaluation of all significant risk factors must be performed in advance to prevent complications. This case report reveals the management of accidental displaced mandibular third molar root into the submandibular space. An 39 years-old male patient underwent a third mandibular molar extraction. Accidentally, the mandibular right third molar distal root was displaced into the submandibular space, making necessary a second surgical step. After 2 days awaiting an asymptomatic health status, the second surgical step was successfully performed using multislice CBCT as preoperative imaging guide. The present case report highlights the clinical usefulness of CBCT in proper treatment of the patient.
