Teeth

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...

Summary

This review identifies common techniques for locating supernumerary teeth, including horizontal tube shift, vertex occlusal, vertical tube shift, and cone-beam computerized tomography (CBCT). CBCT offers 3D views but requires justification due to higher radiation exposure.

Area of Science:

Dentistry
Oral and Maxillofacial Radiology

Background:

Supernumerary teeth are common dental anomalies.
Accurate localization is crucial for treatment planning.

Purpose of the Study:

To review and identify the optimal techniques for localizing supernumerary teeth.
To compare the efficacy of various radiographic and advanced imaging modalities.

Main Methods:

A comprehensive literature search was performed in Medline via PubMed and Cochrane Library.
Keywords included "localization," "radiographs," and "supernumerary teeth."
Citation lists and hand searches supplemented the database search.

Main Results:

Commonly used techniques include horizontal tube shift, vertical tube shift, vertex occlusal, and cone-beam computerized tomography (CBCT).
Conventional radiographs offer 2D views, while 3D imaging provides more accurate localization data.
CBCT provides superior accuracy for impacted supernumerary teeth but involves higher radiation doses.

Conclusions:

Horizontal tube shift, vertex occlusal, vertical tube shift, and CBCT are primary methods for supernumerary tooth localization.
While 3D imaging like CBCT offers precision, its use must be balanced against radiation exposure concerns.
The choice of technique depends on clinical needs and diagnostic information required.
