Abstract:

Introduction: Tooth transposition is considered when two neighboring teeth alter their position in an abnormal pathway. Two types of tooth transposition exist, either complete or incomplete. Th e etiology of tooth transposition is still unknown. Tooth transposition is a rare condition and there were no enough studies to show the exact prevalence of this dental anomaly and the possibly associated dental anomalies in Jeddah, Saudi Arabia. Objectives: To assess the prevalence and the pattern of dental transposition in a Saudi sample and to assess any possible association between transposition and other dental anomalies. Methods: A samples of digital orthopantomogram (OPGs) were collected from the records of patients seeking dental treatment in North Jeddah Specialty Center from 2016-2017. A thorough examination was done to their OPGs. Data were collected and fi lled in excel sheet which categorized into (presence of tooth transposition, hypodontia, impaction, peg shaped laterals, etc.). Results: Regardless of patient�??s age and sex, this research focused on the region of tooth transposition and to which tooth it�??s related. A total of 7 (0.7%) patients found to have tooth transposition. With more predominance in the upper arch, others dental anomalies were noted during OPGs examination. Congenitally missing tooth was the most common anomaly (2.1%), followed by tooth impaction (0.9%), peg shaped lateral (0.6%) and then taurodontism, microdontia, supernumerary and dilaceration were equally distributed (0.3%). Conclusions: Tooth transposition considered a rare phenomenon (0.7%). Upper canine was the most common transposed tooth (85%). Th e most associated anomaly was peg shaped lateral and 3rd molars impaction.
