Tooth rotation, is defined as mesio-lingual or disto-lingual intra-alveolar displacement of the tooth around its longitudinal axis. Such aberrations present a multi–factorial model in their origin. Both genetic and local factors seem to contribute to this abnormality. If the causative local factors and their contributions could be identified, a way could open up to an early treatment and prevention of secondary rotations of opposing and contiguous teeth. Herein, we discuss a case of a 180° rotation of maxillary left second premolar in a female patient.
