“…As this method only requires open apices and teeth length to be measured, it is easier, and more objective compared to other quantitative methods. Some previous study showed that Cameriere's method is more accurate than the widely used Demirjian's or Willems's methods [34][35][36][37][38][39][40].…”

The aim of this study was to evaluate the applicability of Cameriere’s European formula for age estimation in children in South China and to adapt the formula to establish a more suitable formula for these children. Moreover, the performance of dental age estimation based on Cameriere’s method combining the developmental information of permanent teeth (PT) and third molar (TM) was also analysed. Orthopantomographs of 720 healthy children in Group A, and orthopantomographs of 320 children and 280 subadults in Group B were assessed. The samples of Group A were divided into training dataset 1 and test dataset 1, and the samples of Group B were also divided into training dataset 2 and test dataset 2. A South China-specific formula was established based on the training dataset 1, and the comparison of accuracy between the Cameriere’s European formula and the South China-specific formula was conducted with the test dataset 1. Additionally, a PT regression model, a TM regression model, and a combined regression model (PT + TM) were established based on the training dataset 2, and the performance of these three models were validated on the test dataset 2. The Cameriere’s European formula underestimated chronological age with a mean difference (ME) of −0.47 ± 1.11 years in males and −0.69 ± 1.19 years in females. However, the South China-specific formula underestimated chronological age, with a mean difference (ME) of −0.02 ± 0.71 years in males and −0.14 ± 0.73 years in females. Compared with PT model and TM model, the PT and TM combined model obtained the smallest root mean square error (RMSE) of 1.29 years in males and 0.93 years in females. In conclusion, the South China-specific formula was more suitable for assessing the dental age of children in South China, and the PT and TM combined model can improve the accuracy of dental age estimation in children.

“…Development of permanent teeth is a very useful for age estimation method in children. Age estimation in children based on dental development is preferred to methods based on skeletal maturation as the calcification in the teeth is controlled by genes rather than environmental factors (Nair et al, 2018).…”

Dental wear is widely accepted as a physiological consequence of aging, and its evaluation can be a simple tool with which to estimate the age at death of an adult. However, previous studies indicate that age estimation based solely on dental wear is not reliable and does not clarify how the degrees of dental wear are used to reach a final age estimation. Furthermore, most techniques used to measure dental wear rely on an ordinal scale despite the fact that dental wear is a gradual loss. In the present study, we measured the area of exposed occlusal dentine using digital photographs and compared it with estimated age based on changes in the auricular surfaces of the ilia in order to evaluate the relationship between these variables. The amount of exposed dentine on the occlusal surface of the first molar and the degeneration on the auricular surfaces of ilia are moderately correlated. The age estimation method of dental wear should be combined with other methods that demonstrate a strong correlation with age.

“…Regarding the assessment of the dental age, the Demirjian method was used because even though it may indicate differences between the chronological age and dental age, it remains the most used method for determining the dental age [ 28 ]. A number of studies suggest that the method tends to overestimate the age in different populations and that the values need to be adapted for each investigated group [ 29 , 30 ]. In the studied sample of patients, differences were found between dental age and chronological age, but no statistical tests were performed, since the purpose of the study was not to analyze the accuracy of the Demirjian method.…”

Dental caries is a chronic disease that can be influenced by a multitude of factors. Poor oral hygiene and unhealthy eating habits are the most incriminating factors in the onset of dental caries, but age has been proven to impact the disease. The aim of this study was to find correlations between age and the evolution of dental caries in the first permanent molars in children. The retrospective study was conducted based on 400 panoramic radiographs, belonging to Romanian children between the ages of 6 and 14 years. All first permanent molars were investigated, and the carious lesions were classified according to their depth. The chronological age was calculated by subtracting the patient’s date of birth from the date when the radiograph was performed, while for the assessment of dental age, the Demirjian method was used. The gender of the patients did not significantly influence the number of superficial, medium, and deep carious lesions. Most of the identified carious lesions were superficial. Regarding correlations between age and dental caries, there was an association between the decrease in the chronological age and the increase in the number of superficial carious lesions on the first permanent molars and also an association between the increase in the chronological age or dental age and the increase in the number of medium and deep carious lesions on the first permanent molars. Age can impact the development of dental caries in first permanent molars.
