Case Presentation: The present case report is unique, as the dentigerous cysts enclosed the lateral incisor, canine, first and second premolars of the mandible and were accompanied by a complex odontoma, instead of first mandibular molar. Conclusions: Multiple unilateral nosyndromic dentigerous cysts with complex odontoma are found only rarely. The periapical inflammation of non-vital deciduous teeth and trauma may be considered ethiological factors.
