Abstract: Objectives: Age estimation is one of the most important factors in forensic medicine. Measuring secondary dentin deposition using cone-beam computed tomography images is an easy and noninvasive method. The aim of this study was to evaluate cone-beam computed tomography images as a reliable method to estimate chronological age by pulp/teeth ratio in anterior teeth in Iranian population. Methodology: A total of 649 CBCT images from 377 Iranian patients aged between 20 and 69 years were evaluated. Pulp/teeth rati… Show more

“…But other anterior teeth were also examined. Studies found that the secondary dentition of the central maxillary incisor correlated better with age than that of the canines [62]. Ge et al (2016) investigated the question of whether a tooth or tooth type is particularly suitable for age diagnosis using secondary dentin formation [33].…”

“…Conversely, some studies found statistically significant difference between PTVR of males and females. However some studies reported that PTVR of females has stronger association with age (5,15) whereas, others found that PTVR of males more closely associated with age (9,14).…”

“…The relationship between pulp tooth volume ratio (PTVR) and age is not necessarily a straight forward one. The majority of studies using small to moderate sample sizes have reported a linear relationship (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16). However, studies using moderate to large sample size have reported a non-linear relationship between PTVR and age (17,18).…”

“…Imaging techniques have been used for this method, but the accuracy of estimations on two-dimensional radiographs [11] is limited by magnification and distortion [12,13]. The increasing use of three-dimensional images in dental practice has led to research exploring the association between age and pulp/tooth volume ratio in samples from Belgium [3,14], Japan [15][16][17][18][19], India [12,20], Italy [21], China [22], Tunisia [23], and more recently, Malaysia [8,24], Brazil [25,26], Turkey [13,27] and Iran [28,29]. The results have indicated that age can be estimated with reasonable accuracy using three-dimensional images.…”
