“…Maxillary canine teeth were chosen as they are single-rooted teeth with the largest pulp cavity that can be projected entirely on radiograph using an open mouth lateral oblique positioning. The use of radiography allows only two-dimensional evaluation with the disadvantage of the possible occurrence of superimposition and the occurrence of some degree of magnification and distortion (Lee et al, 2020;Niemic, 2019;Thrall & Widmer, 2018) These effects were partly overcome by rotating the heads to position the canine teeth parallel to the table and perpendicular to the X-ray beam (Niemic, 2019;Thrall, 2018) and by calculating ratios instead of real dimensions (Cameriere et al, 2006(Cameriere et al, ,2007a(Cameriere et al, ,2007bKolltveit et al, 1998;Kvaal et al, 1995;Molina et al, 2021;Pinchi et al, 2015).…”

Age determination in dogs is important in many disciplines. For instance, in veterinary clinical practice, knowledge of the exact age of a dog can contribute to establishing a (better) differential diagnosis, prognosis and treatment (Gesierich et al., 2015;Tobias et al., 2000).In zooarchaeology, estimating the age at death of dogs on (bony) remains can give clues in understanding the process of their domestication and the roles dogs played in past societies (Nomokonova et al., 2020). Forensic age estimation, particularly of dogs involved in trade, is yet another application that is gaining more and more importance (Modina et al., 2019;Broeck & Cornillie, 2020). Finally, the adoption of foreign stray dogs is becoming very popular in many Western European countries (Norman et al., 2020). Knowledge of their age can be important for population management (FAO, 2014) and in assessing trainability and longevity after adoption (Tobias et al., 2000;Wells & Hepper, 2000).The most commonly advised age estimation methods for living dogs are the inspection of dental eruption in puppies and the determination of the epiphysial union of the long bones in grow-

“…Most recent work on metric age assessment is based on traditional, atlas-based methods [61,62]. There are also works on adult age assessment [63][64][65]. It seems that the challenge of the 21st century is to develop modern tools that would allow measurements and classifications to be made automatically.…”

The analog methods used in the clinical assessment of the patient’s chronological age are subjective and characterized by low accuracy. When using those methods, there is a noticeable discrepancy between the chronological age and the age estimated based on relevant scientific studies. Innovations in the field of information technology are increasingly used in medicine, with particular emphasis on artificial intelligence methods. The paper presents research aimed at developing a new, effective methodology for the assessment of the chronological age using modern IT methods. In this paper, a study was conducted to determine the features of pantomographic images that support the determination of metric age, and neural models were produced to support the process of identifying the age of children and adolescents. The whole conducted work was a new methodology of metric age assessment. The result of the conducted study is a set of 21 original indicators necessary for the assessment of the chronological age with the use of computer image analysis and neural modelling, as well as three non-linear models of radial basis function networks (RBF), whose accuracy ranges from 96 to 99%. The result of the research are three neural models that determine the chronological age.

“…To overcome the limitations of two-dimensional imaging for age estimation, studies have used three-dimensional modalities for this purpose. Cone beam computed tomography (CBCT) can be used as an accurate and ideal tool to assess dental pulp volume [19,20].…”

Age Estimation Based on Pulp–Tooth Volume Ratio of Anterior Teeth in Cone-Beam Computed Tomographic Images in a Selected Population: A Cross-Sectional Study

et al. 2021

The present study aimed to investigate the correlation between chronological age and pulp–tooth volume ratio in anterior teeth using cone beam computed tomographic (CBCT) images and provide equations for age estimation based on pulp–tooth volume ratio. In this cross-sectional study, CBCT images of 312 anterior teeth of the maxilla and mandible were examineαd. The chronological age and the sex of the patients were recorded. Tooth volume and pulp volume of the anterior teeth were measured using Mimics software, and then tooth–pulp volume ratio was calculated. Statistical analysis of data was performed using chi-square test, independent T-test, Pearson’s correlation, and linear regression (α = 0.05). Finally, equations were made based on the results of the regression analysis for age estimation in general and for males and females. The age of the subjects ranged between 16 and 69 years (mean 40.6 ± 12.74). The pulp–tooth volume ratio of the maxillary teeth was generally higher than the mandibular teeth. A significant inverse relationship between age and pulp–tooth volume ratio was observed for all anterior teeth. (p < 0.05). The strongest correlation between age and pulp–tooth volume ratio was reported for mandibular central incisor (r = −0.58, p < 0.001) and the weakest was for mandibular lateral incisor (r = −0.36, p = 0.012). Age estimation was most accurate among females using the maxillary central incisors (p < 0.001) and among males using the mandibular central incisors and maxillary canines (p = 0.003). Pulp–tooth volume ratio of mandibular central incisors, maxillary lateral incisors, and maxillary canines in males and maxillary and mandibular central incisors, maxillary lateral incisors, and maxillary and mandibular canines in females can be used for age estimation.
