Abstract:
This study investigated the relationship between chronological age and pulp tooth area ratio (PTR) in maxillary central teeth using cone-beam computed tomography (CBCT) images in the Turkish population. The sample consisted of CBCT images of 120 male and female subjects between 14 and 75 years old. The PTR of the maxillary central teeth was calculated using inVivo 5 software (Anatomage, San Jose, CA). Data were analyzed with independent t-test and Pearson's rank correlation test. There was a significant negative correlation between chronological age and PTR (r = -0.615). The results showed that the PTR of maxillary central teeth is a reliable method for age estimation in the Turkish population.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Tooth Anatomy
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...
Beams
Based on geometry, beams can be straight, tapered, or curved. Straight beams are the most common type and have a constant cross-section throughout their length. Tapered beams, on the other hand, have a varying cross-section along...
