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.

Inflammatory dentigerous cyst associated with an endodontically treated primary second molar: a case report

Primary teeth with periapical inflammation induced by dental caries are treated through pulp therapy. Thus in pediatric dentistry, pulpectomy is considered the most common and successful treatment procedure for primary teeth with periapical inflammation. Dentigerous cyst is an epithelial lined cavity that develops from the reduced enamel epithelium related to the crown of an unerupted tooth. This report describes a case of an inflammatory dentigerous cyst associated with an endodontically treated primary second molar in a 12-year-old female patient with mixed dentition.
