Case report of retained deciduous 2nd molars in an adult patient having congenitally missing mandibular 2nd premolars
Keywords:
hypodontia, retained deciduous teeth, adult patientAbstract
Hypodontia is sometimes observed in adult patients and is frequently associated with missing 3rd molars. However, it can also involve other teeth such as canines, lateral incisors and premolars. In this case report, we describe a case of an adult patient having bilaterally missing mandibular second premolars and instead, presence of retained deciduous 2nd molars. Also, a possible insight into the etiology of retained deciduous teeth is discussed.
