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.

Man is blessed with twenty primary teeth that are replaced by thirty two numbers of permanent teeth for his whole life. Teeth which exceed the normal number are termed as supernumerary teeth. Multiple supernumerary teeth are rarely seen. Retention of teeth or impaction is one of the most common developmental dental defects seen among the eruption disorders. However, impaction of multiple teeth is an uncommon finding unless associated with some syndromes or systemic disorders. The present article reports a case of non-syndromic patient having 15 erupted permanent teeth, 10 retained primary teeth, 13 impacted permanent and 11 impacted supernumerary teeth.

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.
