Resum

Introduction. Adentigerous cyst or follicular cyst is defined as a developmental odontogenic cyst of an epitelial origin which represents the second most common entity after the radicular cyst. Generally it is associated with the crown of a permanent unerupted tooth (or semi-erupted) and it tends to be more frequent in males during the second decade of life. The most common location of dentigerous cyst are mandibular third molars followed by the maxillary canines. Due to its asymptomatic behaviour, the diagnosis is reached by routine panoramic radiography, however, the anatomopathologic analysis will define its nature. Case Report. A case report of a 42 and 60 year old females with no medical history of interest, referred to the Oral Surgery Service of the hospital Virgen de la Paloma with a radiotransparent images surrounding the crown of the lower left third molar without associated symptoms. After the extraction of the teeth, cystic lessions are sent for anatomopathological study, which confirm the presumption diagnosis, dentigerous cyst. Patients carried out posterior follow ups showing a positive healing of the bone around the surgical area. Conclusions. Dentigerous cyst represents the second most frequent odontogenic cyst after the radicular cyst at mandibular third lower molars. It is essential to monitor retained mandibular lower third molars for the incipient approach of the pathology.
