Summary
Tooth transposition is a rare dental anomaly with a prevalence of 0.33%. This condition affects males and females equally, with a higher occurrence in the upper jaw and unilaterally.
Area of Science:
- Dentistry
- Oral and Maxillofacial Surgery
- Orthodontics
Background:
- Tooth transposition, a rare developmental anomaly, involves the positional exchange of two adjacent teeth.
- Understanding its prevalence and associated factors is crucial for diagnosis and treatment planning.
Purpose of the Study:
- To systematically review and synthesize existing data on the prevalence of tooth transposition.
- To investigate the relationship between tooth transposition and gender, dental arch, and quadrant occurrence.
Main Methods:
- A comprehensive literature search was conducted across multiple electronic databases.
- Nine studies met the inclusion criteria and were included in a meta-analysis.
- Prevalence was calculated using event rates and random-effect models for 95% confidence intervals.
Main Results:
- The overall mean prevalence of tooth transposition was found to be 0.33%.
- Prevalence did not significantly differ between genders.
- Tooth transposition occurred more frequently in the maxilla compared to the mandible.
- Unilateral occurrences were more common than bilateral occurrences.
Conclusions:
- Tooth transposition is a rare dental anomaly with a consistent prevalence across different populations and genders.
- A predisposition for maxillary involvement and unilateral presentation was observed.
- Further research may elucidate the underlying etiological factors.

01:15Teeth
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 and...

02:13Overview of Transposition and Recombination
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...
01:21Tooth Anatomy
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
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.

01:08Prevalence and Incidence
In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
