| Summary: | Earlier studies on age estimation were unable to accurately estimate the age of
over 20 years of age because they only examined tooth growth and development
morphology from 2D radiographs as measurement parameters. In terms of growth and
development, the tooth pulp volume will decrease in size over the years and this
change can only be seen using 3D radiographs like CBCT. This study proposes that
the tooth pulp volume can be used as a measurement parameter in determining age. As
far as the author is aware, no study has been conducted regarding the measurement of
tooth pulp volume for age estimation in the Deutero-Malay subrace. The general
objectives of this study were to evaluate, develop, and optimize dentomaxillofacial
radiology using CBCT images for age estimation via tooth pulp volume examination
in single-rooted and multi-rooted teeth by gender in the Deutero-Malay subrace. A
cross-sectional study was conducted to analyse tooth pulp volume using CBCT
(Vatech, Korea) and ITK-SNAP 3.6.0 software. In addition, non-linear/logarithmic
regression to examine the correlation between pulp volume decrease in single and
multi-rooted teeth and mathematical models for producing the formula for age
estimation. This study used CBCT data obtained from 16 types of teeth in selected
Deutero-Malay subrace population. The inclusion criteria of the teeth were: without
caries, pulpal calcification, and periapical pathology; the shape and size were normal
without restorations; without artifacts from metal dental material; visible in detail from
CBCT scans; from patients with the chronological age of 10 to 61 years old; and
without root canal treatment. In total, 5760 CBCT data were selected. The study was
conducted at the Radiology Unit of the Dental Hospital at Universitas Padjadjaran,
Bandung Indonesia and Pusat Pengajian Sains Pergigian Universiti Sains Malaysia,
Kelantan. Correlation between tooth pulp volume decrease and the increase of could
be observed from the regression equation: |
