Tooth intrusion is the most common trauma during infancy. We described 11 cases of primary tooth and followed up for a period between 2 and 6 years. Clinical and radiographic examinations and oral color photos were used for the evaluation. The patients who treated in the present study were 1 to 3 years old at the first visit the Pediatric Dental Clinic, Hiroshima University Hospital. Seven cases have been observed satisfactory without surgical treatments such as re-positioning and fixation, and all those re-erupted to the occlusal level of the contra-lateral side within 1.5 year. Otherwise, 4 cases treated with re-positioning and fixation revealed periapical periodontitis in radiographic feature, alveolar abscess formation, or discoloration. It is suggested that cases of intrusion of primary tooth should be observed until some symptom, periapical periodontitis in radiographic feature and alveolar abscess formation, reveals.
