Garré's osteomyelitis of the mandible is chronic osteomyelitis with proliferative periostitis induced by slow stimulation or infection in young people. Garré's osteomyelitis caused by deciduous tooth infection is rare. A case of Garré's osteomyelitis caused by infection of the left second deciduous molar of the mandible, with eruption of permanent teeth after treatment, is reported.An 8-year-old girl came to our hospital because of a painless swelling in the left mandibular angle. X-ray and CT findings showed periosteal reactions and new bone formation, with malposition of the second premolar. Extraction of the decayed teeth and curettage and marsupialization of the premolar lesion were performed under general anesthesia. The histopathologic diagnosis was chronic mandibular osteomyelitis （Garré's osteomyelitis）.On follow-up, there has been no evidence of recurrence. The periosteal reactions and bone formation surrounding the permanent teeth disappeared as of 1 year after operation.
