Age estimation using canine pulp volumes in adults: a CBCT image analysis.

Area of Science:

• Forensic Odontology
• Anthropology
• Radiology

Background:

• Secondary dentine deposition reduces pulp cavity volume over time.
• Pulp cavity volume serves as a potential indicator for age estimation.
• Previous research indicates a correlation between dental age and chronological age.

Purpose of the Study:

• To determine the correlation strength between canine pulp volumes and chronological age.
• To evaluate the influence of sex as a predictor in age estimation.
• To analyze age-related changes in canine pulp volume within a Pakistani population.

Main Methods:

• Utilized cone beam computed tomography (CBCT) images from 719 Pakistani subjects (15-65 years).
• Measured pulp volumes of maxillary and mandibular canines using Planmeca Romexis® software.
• Performed regression analysis to assess the relationship between pulp volume, sex, and chronological age.

Main Results:

• Mandibular canine pulp volume and sex demonstrated the highest predictive power for age (R² = 0.33).
• A statistically significant difference in pulp volume was observed between males and females (p=0.000).
• The relationship between mandibular canine pulp volume, sex, and age exhibited a non-linear, S-shaped curve.

Conclusions:

• The pulp volume of the mandibular canine, in conjunction with sex, provides the most reliable estimation of chronological age.
• This method offers a valuable tool for age assessment in forensic and anthropological contexts.
• Sex is a significant factor influencing pulp volume and its predictive accuracy for age.
