The purpose of this study was to develop a Reference Data Set for Dental Age Assessment at the 13 year old threshold in Caucasian children.
Patients, Materials And Methods:
The Reference Data Set comprised 5187 re-used Dental Panoramic Tomographs (DPTs) between the ages of 11-15 years, from both the Eastman Dental Hospital and King's College Dental Hospital archives. Tooth Development Stages were recorded for the left maxillary and mandibular teeth and all four permanent third molars (Demirjian et al., 1973, Demirjian 1978). A separate Study Sample of DPTs, comprising 50 males and 50 females aged between 10 and 16 years was collected to test the accuracy of the method. Summary Data was generated for the individual Tooth Development Stages which consisted of the number (n-tds), mean (x), standard deviation (sd) and the standard error (se). By using the mathematical techniques of meta-analysis, this data was used to estimate the age of each subject in the Study Sample. The estimated Dental Age derived was compared to the gold standard of Chronological Age.
Results:
The mean difference between the Chronological Age and Dental Age was determined to be -0.1 years (-1.2 months) for males and 0.05 years (-0.6 months) for females.
Conclusion:
Dental Age was reliably estimated at the 13 year threshold.

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...

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.
