BACKGROUND: Dentigerous cysts are slow-growing odontogenic cysts that usually develop unilaterally as part of a pre-existing syndrome. Non-syndromic bilateral dentigerous cysts are extremely rare, but clinicians should be aware of this condition to ensure prompt diagnosis and management and to prevent complications.

CASE REPORT: A case is presented of bilateral mandibular dentigerous cysts that were discovered incidentally in a 44-year-old man who presented for extraction of a retained maxillary deciduous tooth. Histological examination of the tissue specimens following bilateral enucleation confirmed the diagnosis of bilateral dentigerous cysts.

CONCLUSIONS: In this case, incidental bilateral dentigerous cysts were identified and treated by enucleation. The absence of an associated syndrome should not exclude the possibility of the diagnosis of dentigerous cysts, which should be removed to prevent future complications.
