Abstract Background: Various methods are available to assess the age of a child. However, it is much more difficult to evaluate the age of an adult just on the basis of panoramic radiographs. Cameriere’s method based on measurement of pulp/tooth ratio is one of few methods that allows to determine the age of any human being. The aim of this study is to estimate the validation of the original method in a sample of the Polish population and to elaborate a population specific formula.Materials: Panoramic radiographs taken in the Department of Dental and Maxillofacial Radiology, Medical University of Lublin, Poland were retrospectively selected for the study. The selection criteria involved a good quality panoramic radiograph with a free from any pathology upper right canine. The sample included 521 individuals (271 females and 250 males) aged from 18 to 70 years. After tracing and estimating the pulp/tooth area ratio (AR) a dental age was calculated. Afterwards, it has been compared with the chronological age of each patient. Regression models were developed for prediction of the chronological age. Statistical analysis was performed using the Statistica for Windows software (StatSoft).Results: The regression formula for the total group was as follows: age = 91.746 – 481.6 AR. The dental age calculated using these formulations highly correlated with the chronological age. Pearson’s correlation coefficient equalled - 0.844 for the whole group, r = - 0.873 in females and r = -0.815 in males. All correlations were statistically significant (t test p=0.00).Conclusions: Cameriere’s method can be used in evaluating the dental age in the adult Polish population using population specific formula.

Abstract Background: Various methods are available to assess the age of a child. However, it is much more difficult to evaluate the age of an adult just on the basis of orthopantomographs (OPGs). Cameriere’s method based on measurement of pulp/tooth ratio is one of few methods that allows to determine the age of any human being. The aim of this study is to estimate the validation of this method in a Polish population.Materials: OPGs taken in the Department of Dental and Maxillofacial Radiology, Medical University of Lublin, Poland were retrospectively selected for the study. The selection criteria involved a good quality OPG with a free from any pathology upper right canine. The sample included 521 individuals (271 females and 250 males) aged from 18 to 70 years. After tracing and estimating the pulp/tooth area ratio (AR) a dental age was calculated. Afterwards, it has been compared with the chronological age of each patient.

OBJECTIVE: report two cases of age estimation using the method developed by Kvaal et al. (1995).CASE DESCRIPTION: two males, apparently older and without identity documents, underwent age estimation tests by the Public Ministry in order to estimate chronological age. This method proposes a specific formula for dental elements present with error margin of 11.5 years. After this stage, new civil records were carried out, entitling the cases to some social benefits.CONCLUSION: age estimation in living individuals is a challenge but significantly important in the civil and penal spheres, and Kvaal’s technique may be used in Brazilian older adults.

Chronological and dental age are necessary aspects of dental age estimation. Both have a close relationship. Chronological age reflects the age of the tooth, and vice versa. Dental age estimation aims to provide the data in the field of dentistry with an accurate dental age range. In order to get the value of an accurate estimate of dental age, needed a method of estimation that has a standard deviation as low as possible and validated in a specific population groups of an individual. Demirjian method is a method frequently used in the dental age estimation. It uses the classification stages of the seven permanent teeth of mandibular left side using panoramic radiographs. Application of its method in some countries showed vary results so it needed adjustment. Blenkin standard is an adjustment of its method that changes the score of maturity stages 0-H to 1-8 and calculate the dental age by regression formula. The study aimed to assess the dental age estimation using Blenkin standard on children of Javanese ethnic in Jember region. This was an analytic descriptive study design. The samples were panoramic radiographs. The subjects were 70 samples consisting of 29 boys and 41 girls with an age range 6-12 years, and they were divided into 7 groups based on chronological age. Each tooth of the sample was calculated using Blenkin standard. The Blenkin standard showed non-significant difference with the age difference in the amount of approximately -0.22 years for boys and -0.03 years for girls (underestimation).

Objective To analyse the accuracy of a meta-analysis-based dental age assessment (DAA) method in Finnish paediatric patients and to compare the dental development between two generations of Finnish children. Methods Panoramic radiographs of Finnish Caucasian healthy children from two generations (early: born 1981–1984; subsequent: born 1996–2008) were analysed. All developing teeth on the left maxilla and mandible as well as the third permanent molars were analysed following Demirjian’s classification. For each patient, dental age was calculated and compared with chronological age. Dental maturation patterns between the two groups were compared. Results The study included 200 Finnish Caucasian healthy children from two generations (early: aged 7–13 years; subsequent: aged 6–15 years). In the early generation, DAA underestimated the chronological age by a mean of 3.15 years. The underestimation was only 0.11 years in patients < 10 years, but 3.86 years in patients ≥ 10 years. In the subsequent generation, the dental age was overestimated by a mean of 0.34 years; by 0.40 years in patients < 10 years and by 0.08 years in patients ≥ 10 years. Conclusions The present DAA method is applicable to current Finnish children. Differences in dental development between two generations of Finnish children were detected.

Objective: One of the techniques of estimating age in forensic medicine, which is associated with the least trauma in both living individuals and corpses, is to use teeth. Accordingly, the present study aims to determine the relationship between chronological age and pulp-to-tooth area ratio and pulp-to-root width ratio in maxillary and mandibular canines on panoramic radiographs among the Iranian population.  Material and Methods: A total of 162 panoramic radiographs were evaluated in the present study. Selected patients were of verified age with the age range of 15-45 years. The pulp-to-tooth area ratio (PTR) and the pulp-to-root width ratio were calculated with AutoCAD 2016 software program in maxillary and mandibular canines at two points of the root. The two points include cemento-enamel Junction (CEJ) and pulp/root width at the quarter of a distance between CEJ and end point of root-canal, which was named WA, WB respectively. The patients’ age was also estimated with the use of linear regression equation. Then each patient’s chronological age and the age estimated using this technique was compared. Results: The relationship between PTR in both canines and WB variable in maxilla with chronological age was inverse and significant (P < 0.05); However, there was no strong correlation coefficient (r Gender had no effect on the results of the study. The mean difference between predicted age and actual age with combined PTR and WB formula was lower than 1 year. When the mean of PTR or WB variables was considered as a predictor, significant results were obtained (P < 0.05), showing a decrease in Standard error of estimation (SEE). The results were not significant when variables of upper PTR and lower PTR and the interaction between them were included in the linear regression model (p > 0.05). Same results were obtained with the variable of WB. Conclusion: Combining the variables of PTR and WB gives better results than using variables alone. Estimation of age with the mean of each variable shows less error than their combination.   Keywords Age determination; Canine; Panoramic radiography.

Background: Estimation of age has been a major factor in identification of an individual, either living or after death. Objective: To estimate and assess the dental age of children by measuring the open apices of the teeth using panoramic radiograph applying linear regression equation.  Methods: This was a retrospective cross-sectional study conducted on 50 children (25 boys and 25 girls) aged between 5-15 years. The seven left permanent mandibular teeth were assessed using panoramic radiographs which were collected from Medical Record Department, Manipal University, taken during the course of diagnosis and treatment. The number of teeth with closed apical and with open apical end of roots were examined and measured. The values were tabulated and placed on the linear regression equation proposed by Cameriere et al for the estimation of dental age. Result: The result showed no significant difference between the dental age (10.13±1.69 years) and the chronological age (10.31±1.75 years) (p=0.26). The method underestimated the mean age by 0.11 years and 0.23 years for the boys and girls, respectively. The paired sample t- test showed no significant difference between dental age and chronological age for boys (p=0.546) as well as for girls (p=0.351) Conclusion: The estimated age of children by measuring the open apices of the teeth using panoramic radiograph linear regression equation used in the European subjects closely matches with the chronological age in Asian subjects also. Keeping in context to validate more accurately the significance of linear regression equation, there is a need of larger sample size belonging to variety of ethnic and socioeconomic background.DOI: http://dx.doi.org/10.3126/hren.v12i1.11983Health Renaissance 2014;12(1):33-37

Our purpose on the present paper was to verify the reproducibility, the variability and the reliability of the analysis of the dental age (DA) and to assess its relationship with the chronological age (CA). Fifty-three panoramic radiographs from 32 female and 21 male Brazilian children, with ages ranging between 120 and 131 months were submitted to the assessment of their DA according to the general14 and the sex-adjusted15 Standards for the Chronology of Dental Mineralization by four examiners. A high intra-observer and inter-observer reproducibility was found for both sexes. The DA obtained with the general standard was lower than the CA for male and female individuals. With the sex-adjusted standard, we observed that the female individuals tend to have the DA lower than the CA. However, when the values for the CA were subtracted from the values for the DA obtained with the adjusted table, only 13.09% of male individuals and 7.03% of female individuals had the DA out of the acceptable limit of ±12 months. When the CA values were subtracted from the DA values obtained with the general standard, 4.76% of male individuals and 12.5% of female individuals were above or below the acceptable limit of ±12 months. Although the results for the differences between the DA and the CA of some examiners were statistically significant, these differences are clinically irrelevant. The dentists do not need previous experience with the method, since it is based on comparisons of the radiographic images of the teeth with standards of mineralization stages. Based on the results, we concluded that the method is highly reproducible both for the comparisons of the results of one examiner and for the comparison of the results of a group of examiners. As expected, it is applicable to the Brazilian population. The Dental Professionals do not need previous experience with the method, since it is based on the comparison of the radiographic images of the teeth with the stages of dental mineralization.

The chronological age of a person can not provide sufficient information. We can use the dental age in panoramic radiographs to know the growth process appropriately compared to The London Atlas of the Alqahtani method. Children aged 6-12 years have various factors that can affect the velocity in tooth growth and development, such as male and female. This study aims to determine the chronological patient's age differences with dental age based on the Alqahtani method on a panoramic radiograph at Unjani Dental and Oral Education Hospital. This type of research is Analytical Observational with the Cross-Sectional Study method. Research subjects were obtained from all medical records panoramic radiographs with 72 panoramic radiographs aged 6-12 years, divided into 36 male patients and 36 female patients. Differences in chronological age with dental age were analyzed statistically using the Mann-Whitney test and Wilcoxon test, previously tested for the normality using Kolmogorov- Smirnov. The results showed a significant difference between chronological age and dental age by gender and in all patients at the Unjani Dental and Oral Education Hospital (p<0,05). Based on the analysis of the data obtained, all patients in RSGMP Unjani aged 6-12 years have different dental developmental growth processes, and the dental development growth of female patients was faster than male patients. It can be concluded that the dental age is not always comparable with chronological age because of various factors such as gender, genetics and environment, which can affect the dental age.

Objectives: The purpose of this study was to find out the description of chronological age and dental age suitability through estimation of root growth of maxillary and mandibular premolar teeth. Material and Methods: This study was a descriptive study with cross-sectional approach performed on the maxillary and mandibular first and second premolars. Data was taken from 50 panoramic radiographs contained in the 2015-2016 RSGM Unpad archives. Analyzes were performed based on age predictions from the Demirjian table compared to chronological ages in several age groups. The data is then presented in tabular form. Results: This study shows that there is a high degree of concordance between chronological age and dental age through premolars 1 and 2, both upper and lower jaws of the Demirjian table in the initial phase of tooth root formation at 8 years chronological age and at the final phase of root apex closure at 12-13 years chronological age through the assessment of panoramic radiograph.   Conclusion: Chronological age and dental age depend on the precise assessment of root growth of premolar 1 and 2 teeth in the maxillary and mandibular regions having a high degree of suitability in the early and final phases of tooth root formation which are seen more radiographically.
