Root Resorption and Palatal Displaced Canines

Ericson S, Kurol J. Am J Orthod Dentofacial Orthop 1988; 91: 483-92. Cases with lateral incisor root resorption showed a more advanced dental development, a more medial canine position, and more mesial horizontal path of eruption than that of the control cases.	Rimes RJ et al. Eur J Orthod 1997; 19: 79-84. Root resorption of the incisors is often diagnosed late and underestimated by the clinicians.
Ericson S, Kurol J. Angle Orthod 2000; 70: 415-23. CT images increased the detection of root resorptions on incisors 48%. It is a more common phenomenon than previously believed.	Liu DG et al. Oral Surg Oral Med Oral Path Oral Radiol Endod 2008; 105: 91-8. In CBCT images of 210 impacted maxillary canines showed root resorption in 27.2% of lateral and 23.4% of central incisors.
Alqerban A et al. Am J Orthod Dentofacial Orthop 2009; 136: 764-5. CBCT could detect slight and severe root cavities much better than panoramic radiographs.	Haney E et al. Am J Orthod Dentofacial Orthop 2010; 137: 590-97. They showed a 37% disagreement in the perception of root resorption of the adjacent teeth between the 2D and 3D images.
