The teeth most likely to be transposed are:

 # The teeth most likely to be transposed are:

A. Mandibular Premolars and maxillary incisors

B. Maxillary premolars and mandibular incisors

C.  Maxillary molars and canines

D. Mandibular molars and canines

The correct answer is B. Maxillary premolars and mandibular incisors.

Transposition is a rare positional interchange of two adjacent teeth. It occurs with a prevalence of approximately 0.3% and equally affects males and females. The teeth most likely to be transposed

are mandibular incisors and maxillary premolars, and this usually occurs as a consequence of ectopic eruption. There appears to be a genetic component to this problem. In the early mixed dentition years, transposition can develop when distally directed eruption of the permanent mandibular lateral incisor leads to loss of the primary mandibular canine and primary first molar. If left untreated, this can result in a true transposition of the permanent lateral incisor and canine.
