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. The relation between endodontic treatment and development of dentigerous cyst is discussed.

Supernumerary teeth are the teeth which are more in number in addition to the normal number found in either primary or permanent dentition. Paramolar is a supernumerary structure occurring buccally or lingually near the molars and it may be caused by combination of genetic and environmental factors. Reports of this unique entity are rarely found in the literature. The present article reports a case of paramolar in the maxillary molar region in an 11-year-old female patient and also reviews the literature about paramolar.
