【 摘 要 】

Introduction: tooth eruption is a complex process and due to this complexity flaws mayappear in it.Objective: present a clinical case of a dentigerous cyst in an inverted mandibular thirdmolar.Clinical case: a male 36-year-old patient reports having visited a dental clinic for discomfortin the right mandibular region. Orthopantomography was indicated which revealedthat tooth 48 was retained; the patient was therefore referred. Clinical oralexamination detected the absence of tooth 48 and an expanded vestibular tablein the area. The orthopantomograph showed root resorption of tooth 47 in thearea of the right molars, with 48 in an inverted position and a radiolucentimage of clear-cut boundaries in relation to the crown of 48. Exeresis of 47and 48 was performed under local anesthesia, and the lesion responsible forthe mandibular radiolucent image was removed by curettage. Histopathologicalexamination of the lesion was indicated, revealing the presence of a dentigerouscyst. Postoperative evolution was satisfactory.Conclusions: the infrequent presence of a dentigerous cyst as a complication of dentalretention in an inverted mandibular third molar prompted the use of the benefitsoffered by digital imaging studies and the clinical method to develop a treatmentplan leading to successful exeresis of the teeth involved and the associatedlesion, without any perioperative complications.
