Teeth

394
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 summary is machine-generated.

Dental pulp width in the maxillary central incisor can reliably estimate age. This study used cone-beam computed tomography (CBCT) to analyze pulp width and predict age in individuals aged 14-64.

Area of Science:

  • Forensic Anthropology
  • Dental Radiology
  • Age Estimation Techniques

Background:

  • Accurate age estimation is crucial in forensic and clinical contexts.
  • Dental metrics offer a non-invasive approach to age assessment.
  • Pulp dimensions change predictably with age.

Purpose of the Study:

  • To evaluate the correlation between maxillary central incisor pulp width and chronological age.
  • To develop a predictive model for age estimation using 3D radiographic analysis.

Main Methods:

  • 185 cone-beam computed tomography (CBCT) scans of individuals aged 14-64 years were analyzed.
  • Pulp width measurements of maxillary central incisors were taken at the cementoenamel junction and middle third of the root.
  • Correlation and regression analyses were performed to establish age prediction formulas.

Main Results:

  • A significant negative linear relationship was observed between pulp width and age.
  • The standard error of estimate (SEE) for age prediction was approximately 11.3 years.
  • Regression formulas derived were statistically significant, with improved accuracy when samples were divided into age groups.

Conclusions:

  • Pulp width of the maxillary central incisor is a viable indicator for age estimation.
  • 3D radiographic evaluation provides a reliable method for assessing dental age.
  • Further research with stratified age groups can enhance predictive accuracy.
