Maxillary second molar with single root and single canal: A case series

Maxillary second molars are generally considered to have three roots and three or four canals. In the literature, various cases of maxillary second molars have been reported with more number of roots and root canals, but only very few cases have been reported with less number of roots and root canals. This article reports about the diagnosis and endodontic management of maxillary second molars with single root and single canal, as failure to identify such configuration may lead to poor prognosis due to excessive removal of the dentin in search of canals.
