Short-root anomaly is an idiopathic condition that can occasionally be associated with an autosomal dominant pattern of inheritance. It affects about 1.3% of the population and is more prevalent in women. Caused by incomplete root development rather than resorptive processes, it is usually confined to the upper incisors or premolars, but may sometimes affect the entire dentition, when it is known as generalized short-root anomaly. Short-root anomalies may be associated with systemic conditions such as dysplasia type 1, scleroderma, thalassemia, Stevens-Johnson syndrome, Aarskog syndrome, Down syndrome, or Rothmund-Thomson syndrome.

The canines have the highest reported incidence of dental transposition - most commonly with the first premolar, followed by the lateral incisor. Several authors have described cases in which canine transpositions were resolved or the teeth were aligned in their transposed positions. To our knowledge, however, no one has reported treating a patient in whom bilaterally impacted upper canines were transposed with the lateral incisors and were also associated with severe root resorption of adjacent teeth. Canine transposition is one of the most common causes of tooth resorption. Typically, an upper lateral-incisor root is affected by ectopic eruption of the adjacent canine, although central incisors can also be involved. The apical and middle thirds of the incisor roots are most likely to be resorbed.

A 12-year-old patient with five impacted upper anterior teeth is successfully treated with surgical exposure and orthodontic forced eruption. After space preparation and extraction of four first premolars, the impacted teeth are brought into the arch, and an impacted upper second premolar is erupted in the same way.
