The most common teeth affected are impacted mandibular third molars and permanent maxillary canines. This case involves a dentigerous cyst encompassing the right and left impacted mandibular canines and crossing the midline. This is to the best of our knowledge the first reported case of a dentigerous cyst encompassing non-adjacent teeth and crossing the midline. Case presentation The patient presented to our orthodontic clinic for treatment of malocclusion. The patient was a 10-year one-month-old Caucasian girl with a dentigerous cyst encompassing the right and left impacted mandibular canines and crossing the midline. Conclusion This case involves an unusual clinical and radiographic presentation of a dentigerous cyst. It shows a new variant of presentation that medical professionals specifically dentists and radiologists should be aware of since a dentigerous cyst crossing the midline has not been previously reported as far as we are aware. This additional knowledge is important for inclusion on differential diagnosis lists and aids in the development of a proper treatment plan. Introduction Dentigerous cysts are the most common developmental odontogenic cysts accounting for approximately 25 of all odontogenic cysts of the jaws. They are frequently noted as an incidental finding on radiographs because a majority of these cysts are asymptomatic and are most commonly associated with impacted mandibular third molars and permanent maxillary canines 1 2 .
