Teeth

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 and...

Tooth Anatomy

Tooth 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.

Summary

Non-syndromic multiple supernumerary teeth (NSMST) are rare, with this study analyzing 46 cases. Findings indicate NSMST occurs more in males but shows no gender differences in tooth number or location, with bilaterality being common.

Area of Science:

Dentistry
Genetics
Oral Pathology

Background:

Non-syndromic multiple supernumerary teeth (NSMST) is a rare condition.
Literature primarily consists of case reports, limiting comprehensive understanding.

Purpose of the Study:

To characterize NSMST by analyzing reported cases.
To identify patterns in prevalence, number, and location of supernumerary teeth.

Main Methods:

Systematic literature search of PubMed, Web of Knowledge, Science Direct, and Scopus.
Data extraction included age, gender, tooth count, location (maxilla/mandible), and dental series.
Analysis of bilaterality and distribution within arches.

Main Results:

Analyzed 46 cases (mean age 19 years, 2.14:1 male:female ratio).
Documented 393 supernumerary teeth: 43.26% in maxilla, 56.74% in mandible.
No significant gender differences in total number, dental series involvement, or arch distribution.

Conclusions:

NSMST shows a higher incidence in males, but tooth number and location are similar across genders.
Bilaterality appears to be a common feature of NSMST.
