“…Further analysis from Gulsahi et al suggested that mandibular canine pulp-tooth ratio ( R 2 0.210) was better than maxillary canine ( R 2 0.153) [41]. The results from Biuki et al ranged from R 2 0.65 to 0.75 for maxillary anterior teeth and R 2 0.60 to 0.76 for mandibular anterior teeth [18]. Marroquin et al assessed the effect of sex on the regression models.…”

“…Age estimation research is highly affected by the number of individuals in each group and selected age range in sample size [18, 28, 29]. Most of the studies lack the uniform distribution of sample size; therefore, a large data sample size characterized by homogenous age distribution (i.e., approximately equal numbers of individuals in each age range) was used in this study to estimate the age and correlation from pulp volumes of canines.…”

Secondary dentine deposition is responsible for the decrease in the volume of the pulp cavity with age. Therefore, the volume of the pulp cavity can be considered as a predictor for estimating age. The aims of this study were to investigate the relationship strength between canine pulp volumes and chronological age from homogenous (approximately equal numbers of individuals in each age range) age distribution and to assess the effect of sex as predictor in age estimation. This study was performed on 719 subjects of Pakistani origin. Cone beam computed tomography images of 521 left maxillary and 681 left mandibular canines were collected from 368 females and 349 males aged from 15 to 65 years. Planmeca Romexis® software was used to trace the outline of the pulp cavity and to calculate pulp volumes. Regression analysis was performed to assess the correlation between pulp volumes considering with and without sex as a predictor with chronological age. The obtained results showed that mandibular canine pulp volume and sex have the highest predictive power (R2 = 0.33). The relationship between mandibular canine pulp volume and sex with chronological age demonstrates an odd S-shaped non-linear relationship. A statistically significant difference in volumes of pulp was found (p = 0.000) between males and females. The conclusion was that predictions using the pulp volume of the mandibular canine and sex produced the best estimates of chronological age.Electronic supplementary materialThe online version of this article (10.1007/s00414-019-02147-5) contains supplementary material, which is available to authorized users.

“…Outside of the pulp, there are odontoblasts that form dentin throughout the lifetime, which can reduce the pulpal canal size. Dentin and tooth pulp experience age-related pathological and physiological changes 56789. Measuring these morphological changes requires cutting teeth, which is not feasible in vivo , so the methods used to estimate age depend on radiological imaging of the tooth 8910…”

“…Each tooth can be utilized to determine age; however, the canines are particularly suitable candidates for age estimation since they are commonly found at older ages, are less prone to rot, and have a large root and pulp 5678…”

Purpose It has been proposed that using new prediction methods, such as neural networks based on dental data, could improve age estimation. This study aimed to assess the possibility of exploiting neural networks for estimating age by means of the pulp-to-tooth ratio in canines as a non-destructive, non-expensive, and accurate method. In addition, the predictive performance of neural networks was compared with that of a linear regression model. Materials and Methods Three hundred subjects whose age ranged from 14 to 60 years and were well distributed among various age groups were included in the study. Two statistical software programs, SPSS 21 (IBM Corp., Armonk, NY, USA) and R, were used for statistical analyses. Results The results indicated that the neural network model generally performed better than the regression model for estimation of age with pulp-to-tooth ratio data. The prediction errors of the developed neural network model were acceptable, with a root mean square error (RMSE) of 4.40 years and a mean absolute error (MAE) of 4.12 years for the unseen dataset. The prediction errors of the regression model were higher than those of the neural network, with an RMSE of 10.26 years and a MAE of 8.17 years for the test dataset. Conclusion The neural network method showed relatively acceptable performance, with an MAE of 4.12 years. The application of neural networks creates new opportunities to obtain more accurate estimations of age in forensic research.

“…Micro-computed tomography (Micro-CT) allows for the 3-dimensional quantitative analysis of dental structures, but it is an unsuitable method for the prediction of age in living individuals. Cone Beam Computed Tomography (CBCT) is used frequently in age estimation methods and allows the 3D (dimensional) evaluation of dental structures without superposition and distortion (1,5,(16)(17)(18)(19)(20)(21)(22). However, periapical and panoramic radiography techniques that give a 2D image provide more limited imaging compared to CBCT, but it allows the living individuals to be exposed to less ionized radiation (1).…”

Objective: In this study, it was aimed to evaluate the relationship between chronological ages and pulp areas of mandibular canine teeth of patients that received and not received orthodontic treatment. Methods: 102 patients that completed fixed orthodontic treatment and between the ages of 13-24, and 102 age and sex-matched control group subjects were included in the study. A total of 204 dental panoramic radiographs taken with the same procedures and with the same device (Soredex; Cranex Novus, Tuusula, Finland) were evaluated in this study. The pulp areas of the mandibular canine teeth were measured using the Image J software (US National Institutes of Health, Bethesda, MD). Data were analyzed statistically. Results: In both the orthodontic group (r =-0,511) and the control group (r =-0,592), there was a negative correlation between chronological age and pulp area. There was no significant difference between the groups in terms of the pulp area and gender (p >0.05). Conclusion: Orthodontic treatment did not result in a significant difference in the correlation between the pulp area and the chronological age.
