ABSTRACT

Dental transposition is a rare anomaly, the frequency being around one case in every 300 patients. It affects only permanent teeth and is more common in the maxilla. It can be unilateral or bilateral. Objectives: To determine the frequency of dental transposition, in which sex it is more common, and which teeth are most commonly affected. Material and methods: A descriptive, cross-sectional, retrospective study was performed. The sample consisted of 445 pretreatment orthodontic study models; the sample size was calculated with a confidence level of 99% and error of 3%, the prevalence being estimated as 10%. The models included were those with all teeth erupted, except for the third molars: teeth in which the anatomy may have been altered by wear, fractures, cavities, and restorations were excluded. Conclusions: The frequency of transposition was 1.3%, being higher in women (2%) than in men (0.5%).
