Eruption cyst: a literature review and four case reports.

Eruption cyst is a benign cyst associated with a primary or permanent tooth in its soft tissue phase after erupting through the bone. It is most prevalent in the Caucasian race. Intraoral examination of four patients revealed eruption cyst. Among these, in three patients it occurred in the maxillary arch and one had it in the mandibular arch. All were associated with permanent tooth. Surgical treatment was done in three cases and in one case the cyst disappeared gradually and tooth erupted in normal pattern. Four cases of eruption cyst from India are presented and literature on this condition is reviewed. It is clinically significant in that knowledge among general dentists is very essential regarding this developmental disturbance to reach the correct diagnosis and to provide proper treatment.
