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.

Background:

Accurate dental age estimation is crucial for pediatric health assessment and forensic identification.
Existing dental age assessment methods, like Demirjian's, require population-specific calibration.
Establishing a regional reference database for dental development is essential for accurate age estimation in Spanish children.

Purpose of the Study:

To establish a chronological reference for dental development stages in Spanish children based on Demirjian's method.
To create a localized database for dental age assessment in the Spanish population.
To compare dental development timelines between boys and girls in the studied sample.

Main Methods:

Analysis of 1010 orthopantograms from Spanish children aged 2-16 years.
Application of Demirjian's method for dental age calculation.
Statistical comparison of dental development onset and age estimation between genders.

Main Results:

Girls generally exhibit earlier dental development than boys, with statistically significant differences in specific teeth and stages.
Canine teeth show greater sexual dimorphism in dental development compared to other teeth.
Demirjian's method significantly overestimated dental age in both boys (0.87 years) and girls (0.55 years) in this Spanish cohort.

Conclusions:

The study provides a valuable reference for dental maturity and age estimation in Spanish children.
Findings highlight the need for population-specific adjustments when using Demirjian's dental age assessment method.
The established database can aid pediatricians, orthodontists, and forensic experts in the region.
