Normal eruption of impacted teeth associated with a dentigerous cyst managed by simple extraction and decompression

Dentigerous cyst is an epithelial-lined cavity that encloses the crown of an unerupted tooth at the cementoenamel junction, can be either developmental or inflammatory in origin. The purpose of this paper was to report of an asymptomatic dentigerous cyst of inflammatory origin in a 7.5-year-old child who was managed by conservative means of a simple extraction, followed by decompression under local anesthesia. After 16 months of follow-up, the cyst was completely ossified, and the displaced premolars were normally erupted in the oral cavity. Similarly, we also noticed rapid root maturation of the cyst involved premolars than the contralateral premolars.
