Canine Transposition - Prevalence, Distribution and Treatment Considerations among Orthodontic Patients
The Journal of Clinical Pediatric Dentistry
|November 9, 2020
Summary
Canine transposition, a rare dental anomaly, affects 0.5% of orthodontic patients, predominantly females. Treatment options range from extraction to repositioning, with correction offering the best aesthetic results.
Area of Science:
- Dentistry
- Orthodontics
- Dental Anomalies
Background:
- Tooth transposition is an uncommon dental anomaly where adjacent teeth swap positions.
- Canine transposition specifically involves the canine tooth and an adjacent tooth.
Purpose of the Study:
- To determine the prevalence and distribution of canine transposition in orthodontic patients.
- To explore treatment alternatives and outcomes for canine transposition.
Main Methods:
- A retrospective review of 3000 orthodontic patient records from a university clinic.
- Data collection included gender, age, number, and location of canine transpositions.
Main Results:
- Canine transposition was detected in 15 subjects (0.5% prevalence).
- The anomaly was more frequent in females (4:1 ratio) and on the left side.
- Maxillary arch involvement was more common, with transpositions occurring between canines and lateral incisors or first premolars.
Conclusions:
- The prevalence of canine transposition is 0.5%, with a higher incidence in the maxilla.
- Treatment strategies include extraction, alignment in situ, or orthodontic correction.
- Orthodontic correction of canine transposition yields the most favorable aesthetic outcomes.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.

Transposons make up a significant part of genomes of various organisms. Therefore, it is believed that transposition played a major evolutionary role in speciation by changing genome sizes and modifying gene expression patterns. For example, in bacteria, transposition can lead to conferring antibiotic resistance. Movement of transposable elements within the genetic pool of pathogenic bacteria can aid in transfer of antibiotic-resistant genetic elements. In eukaryotes, transposons can carry out...
