  Abstract 


Tooth transposition is a reversal of position between two teeth in the same quadrant of the dental arch, which can be complete tooth transposition or incomplete tooth transposition, multifactorial causes, and may be associated with other dental anomalies; tooth transposition can be considered a rare phenomenon. Here, we present dental transposition of the central and lateral incisor and associated with supernumerary teeth.

Keywords: Maxillary tooth, supernumerary teeth, tooth transposition

  Introduction Top


Tooth transposition can be defined as an unusual type of ectopic eruption where a permanent tooth develops in the position normally occupied by another permanent tooth.[1] It is considered to be a rare occurrence affecting <1% of the population; the upper arch is more affected than the lower arch. It is considered as “complete transposition” or “true transposition” when the crowns and the roots of the involved teeth exchange places in the dental arch and “incomplete transposition” or “pseudotransposition” when the crowns are transposed, but the roots remain in their normal position. Exact etiology is still unknown and it is an area of controversy; many theories have been proposed including from genetic influences within a multifactorial inheritance model.[2],[3]

It is more common in females and usually unilateral. The maxillary permanent canine is the most commonly involved, transposing with the first premolar in 80% of cases and with the lateral incisor in 20%. Dental transposition of the central and lateral incisor can be considered a rare phenomenon.[4],[5] Association of dental anomalies has been reported more frequently in transposition cases than in a normal population.

Here, we present dental transposition of the central and lateral incisor and associated with supernumerary teeth.


  Case Report Top


This was a case of transposition observed in an African 19 years old female with no history of any trauma data of clinical records, intraoral photographs, and radiographs of the patient being recorded; tooth transposition was diagnosed according to Peck and Peck[2] and confirmed both clinically and radiographically. Clinical image [Figure 1]a and [Figure 1]b, radiograph (orthopantomogram [OPG]), [Figure 1]c, and intraoral periapical (IOPA) [Figure 1]d were used to confirm the presence of a true transposition of Mx.C.I2 and associated with supernumerary teeth with 13 region.

  Discussion Top


Tooth transposition is an ectopic eruption in which tooth changes the normal order of the tooth sequence in the same arch. The exact etiology is being controversy, with multifactorial causes of inheritance. Various theories have been proposed for this condition, such as (a) interchange of developing tooth buds or migration of a tooth during eruption, (b) retained primary teeth, (c) mechanical interferences, (d) genetic factors, (e) trauma of the dental lamina, and (f) heredity. Tooth transposition can be associated with dilacerations, retained deciduous canines cone-shaped lateral incisor, rotations, and hypodontia. Very few studies for the prevalence of dental transposition have been reported 0.14%–0.38% in Nigeria, 0.41% in India, 0.13%–0.64% in Greece, 0.09% in Germany, 0.13% in Saudi Arabia, and 0.27%–0.33% in Turkish population; all the reports suggest that tooth transposition can be considered a rare anomaly.[3],[4],[5],[6],[7],[8],[9]

Dental transposition is quite simple to identify by clinical examination, confirmatory diagnosis for the type of transposition can be done with obtaining Orthopantomogram (OPG) or Intraoral periapical (IOPA) radiographs. There is a contrast of dental transposition observations in the literature for its prevalence, gender, affecting the type of dentition and arch.[4] In the present case it was an African female involving maxillary dentition on the right side and associated with supernumerary teeth [Table 1].

  Conclusion Top


Early diagnosis and detection by clinicians are important to prevent malocclusion and certainly esthetic will be a major concern. Ideally, the treatment objectives would include the full resolution of the transposition. However, the achievement of this objective might subject the transposed teeth to mechanics that have significant root resorption risks.[3],[10]
