Prevalence of Tooth Transposition

Abstract

Objective: To synthesize currently existing data and investigate the prevalence of tooth transposition as well as its relation to gender, dental arch, and quadrant occurrence. Materials and Methods: Several electronic databases were searched in order to identify the potentially relevant studies. Initially, 591 papers were retrieved. After applying specific inclusion and exclusion criteria, nine studies were eligible for inclusion in this evaluation. Meta-analysis was performed by determining the event rate and the 95% confidence intervals estimated by the random effect model. Results: Analysis of the data of the primary studies revealed that tooth transposition has a mean prevalence of 0.33%. This prevalence seems to be the same between the two genders. However, tooth transposition appears more frequently in the maxilla than in the mandible and more unilaterally than bilaterally. Conclusion: Tooth transposition is a rare phenomenon that affects various populations, including across genders, in a similar manner. Some maxillary predisposition exists, and its unilateral occurrence is higher than that of bilateral. (Angle Orthod. 2010;80:275-285.)

The aberrant canine part 1: aetiology and diagnosis

“…This can happen in both the upper and lower arch and is relatively rare, with a reported incidence in the upper arch of 0.3% 8 . The most common transposition is maxillary canine transposed to first premolar position 9 .…”

“…Ancak alt çeneye oranla üst çenede, çift taraflıya oranla tek taraflı transpozisyonların gö-rülme sıklığının daha fazla olduğu saptanmıştır. 3,9 Bu olgu çalışmada ise tek taraflı Mx.U2.C diş transpozisyonu bulunan hastanın çekimsiz sabit ortodontik tedavi sonuçları gösterilmiştir.…”

“…2,9 Bu çalışmada, Peck ve ark., tarafından tanımlanmış olan tipik bir Mx.U2.C unilateral transpozisyon olgusunun çekimsiz sabit ortodontik tedavi sonuçları gösterilmiştir. 2 Diş transpozisyon vakalarının tedavi planlamasında hasta yaşı, periodontal destek dokularının durumu, mevcut oklüzyon, tahmini tedavi süresi ve hasta kooperasyonu dikkatli bir şekilde değer-lendirilmelidir.…”
