Additional Root of the Primary Maxillary Second Molar Possibly Associated with Displacement and Rotation of the Permanent Successor : Two Case Reports

구재원; Je-Woo Lee; Jiyoung Ra

An additional root of the primary maxillary second molar is rarely observed. Two cases are presented herein, and we discuss a possible association between additional root of the primary maxillary second molar and displacement and rotation of the permanent successor. Investigation of crown morphology enables the detection of a potential additional root of the primary maxillary second molar, and eruption of the permanent successor needs to be examined carefully if an additional root is present. Early extraction of primary molar and space maintenance can be used as a conservative treatment if the premolar germ shows an abnormal eruption pattern.
