Teeth
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 and...
Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

Tooth transposition, a rare dental anomaly, affects 2% of orthodontic patients, predominantly females. This condition, most common in canines within the maxillary arch, often co-occurs with other dental issues.

Area of Science:
- Dentistry
- Orthodontics
- Dental Anomalies
Background:
- Tooth transposition is a rare dental anomaly where teeth erupt in an abnormal position.
- Understanding its prevalence is crucial for orthodontic diagnosis and treatment planning.
Purpose of the Study:
- To investigate the prevalence of tooth transposition in a cohort of orthodontic patients.
- To identify associated dental anomalies and demographic patterns.
Main Methods:
- Retrospective analysis of 547 orthodontic patient records.
- Inclusion of clinical data, panoramic radiography, cephalograms, and dental casts.
- Application of the Peck and Peck (1995) classification for tooth transposition.
Main Results:
- A 2% prevalence of tooth transposition was observed.
- The anomaly predominantly affected the maxillary arch, with canines being the most involved teeth (100%).
- Associated conditions included tooth agenesis (18%), peg lateral incisors (27%), and persistent deciduous teeth (18%).
Conclusions:
- The prevalence of tooth transposition in this orthodontic population was low but higher than previously reported.
- Findings highlight the importance of recognizing associated anomalies for comprehensive orthodontic care.
