Observation of a child with multiple submerged primary teeth.

The authors presented a case report of a seven-year-old male with eight submerged primary molars and a primary lateral incisor. Two major treatment modalities, tooth extraction and observation, were reported. In this case we applied the two alternative modalities and observed the patient for five years. The permanent successors were in the process of almost normal eruption after the extraction of the submerged primary teeth; no eruption and more severe submerging were observed, however, in the permanent successors of the submerged primary teeth that were not extracted. These results suggest that submerged or impacted primary teeth should be extracted immediately when they are moderately or severely submerged.
