ABSTRACT

OBJECTIVES:

To evaluate the feasibility of using the pulp volume (Pv) to total volume (Tv) ratio (PvTv), obtained from cone beam computed tomography (CBCT) scans of single-rooted teeth, for age estimation in a Brazilian population sample.

METHODS:

After obtaining approval from the ethics committee, the study commenced by applying inclusion criteria to screen CBCT scans, resulting in a probability-based sample of participants aged 18 years and older (ranging from 18 to 82 years, with a mean age of 46.44 years). A total of 517 single-rooted teeth, including maxillary central incisors (CI), mandibular canines (C), and mandibular first premolars (FP), were chosen based on excellent agreement values (> 0.9). Pv and Tv measurements were conducted using semi-automatic segmentation with ITK-SNAP 3.8 software. Statistical analysis was performed using Jamovi software, with a significance level set at 5% (α = 0.05).

RESULTS:

A strong negative correlation (r > -0.7) was observed between chronological age and the PvTv ratio across all examined teeth. However, when conducting regression analysis with PvTv data and chronological age as the independent variable, only the mandibular FP teeth exhibited a normal distribution. The resulting linear model demonstrated moderate predictive value (approximately 64%) in explaining the variance in chronological age, but caution should be exercised when interpreting these findings.

CONCLUSIONS:

The method of measuring individual tooth volume using CBCT to estimate chronological age via PvTv has been demonstrated as effective and reproducible within the Brazilian population sample.
