ABSTRACT

Introduction: tooth eruption is a complex process and due to this complexity flaws may appear in it.
Objective: present a clinical case of a dentigerous cyst in an inverted mandibular third molar.
Clinical case: a male 36-year-old patient reports having visited a dental clinic for discomfort in the right mandibular region. Orthopantomography was indicated which revealed that tooth 48 was retained; the patient was therefore referred. Clinical oral examination detected the absence of tooth 48 and an expanded vestibular table in the area. The orthopantomograph showed root resorption of tooth 47 in the area of the right molars, with 48 in an inverted position and a radiolucent image of clear-cut boundaries in relation to the crown of 48. Exeresis of 47 and 48 was performed under local anesthesia, and the lesion responsible for the mandibular radiolucent image was removed by curettage. Histopathological examination of the lesion was indicated, revealing the presence of a dentigerous cyst. Postoperative evolution was satisfactory.
Conclusions: the infrequent presence of a dentigerous cyst as a complication of dental retention in an inverted mandibular third molar prompted the use of the benefits offered by digital imaging studies and the clinical method to develop a treatment plan leading to successful exeresis of the teeth involved and the associated lesion, without any perioperative complications.
