title: [Secondary retention of a permanent tooth].
abstract: The authors report of a case of secondary retention of a lower first molar. It turned out to be a true "re-inclusion" of the tooth without involvement of the antrum. The radiograph of a central metal filling performed 10 years ago also suggests a retrograde movement of this teeth and its re-inclusion in the mandible.
