1. Introduction An ectopic permanent molar is defined as a local disturbance in the developing dentition [1]. It can present as an abnormal alteration, deviation, or drifting of the tooth eruption pathway, which results in the first or second permanent molars erupting in contact with the distal undercut of the second deciduous molar or first permanent molar, respectively, instead of erupting into the normal occlusal plane [1].
