Summary
This study adapted Demirjian
Area of Science:
- Dentistry
- Pediatric Dentistry
- Forensic Anthropology
Background:
- Accurate dental age estimation is crucial for pediatric health assessment and forensic identification.
- The Demirjian method is a widely used technique for assessing dental maturity.
- Previous studies have shown variations in dental age estimation across different populations.
Purpose of the Study:
- To apply Demirjian's dental age calculation method to a Spanish pediatric sample.
- To compare estimated dental age with chronological age in Spanish children.
- To develop population-specific conversion tables and curves for dental age assessment.
Main Methods:
- Analysis of 1010 orthopantograms from Spanish children aged 2-16 years.
- Application of Demirjian's dental maturity stages (A-H) to assess dental development.
- Statistical comparison of dental age and chronological age, with development of conversion tables.
Main Results:
- Mean dental age exceeded mean chronological age in both boys (0.87 years) and girls (0.55 years).
- Significant differences observed between dental and chronological ages across the studied age range.
- Customized conversion tables and curves were generated for the Spanish pediatric population.
Conclusions:
- The Demirjian method requires adaptation for accurate dental age estimation in Spanish children.
- Population-specific reference data are essential for reliable dental age assessment.
- The developed tables and curves can aid clinicians and forensic experts in evaluating Spanish pediatric cases.

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...

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.

01:26Assessment of the Mouth
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
