“…Recently, there has been an increasing need for fast and inexpensive methods for age determination ( 18 ). Chronological age assessment methods with the help of dental maturation follow-up have been performed by many researchers ( 13 , 14 , 19 , 20 , 21 ).…”

Purpose: Dental age assessment is one of the most reliable methods of chronological age estimation used for criminal, forensic and anthropologic purposes. This study aimed to determine how accurate it was to estimate the chronological age by looking at the dental age measured with the Nolla and Demirjian methods in a Turkish sample, based on the variables of gender and age-group. Materials and methods: A retrospective study was performed on panoramic radiographs of 1587 subjects (774 females and 813 males), aged 3–17 years. The mean dental age according to the Demirjian and Nolla methods were compared to the mean chronological age (CA). Also, the percentage value of prediction of CA was determined by using the both methods. Results: An under-estimation of the chronological age was observed by using Nolla’s method (males -0.003, females -0.32, both -0.16) and an over-estimation of the dental age was observed by using Demirjian’s method (males 0.61, females 0.75,both 0.68). Conclusion: Nolla’s method was more accurate in the CA estimation than Demirjian’s method in Eastern Turkish population.

“…Numerous authors have shown that Demirjian's approach is the gold standard for determining a person's age based on their teeth, hence this is the technique that was used in the study. [9], [10], [11], [12], [13], [14] Participants in this crosssectional study were assigned at random to one of many age groups. The approach, most likely, has the benefit of rapidly amassing data on enhancement throughout a wide range of ages.…”

Background: Understanding growth, which may be one of the most elusive variances, is critical for diagnosis and therapy planning. It has been common practice to use a child's skeletal age or dental age as a proxy for their actual age. Multiple studies have looked at how various populations' dental and skeletal maturity rates correlate with chronological age. The current research aimed to replace skeletal age estimate with dental age estimation in the community. Methods: “In all, 104 samples were collected, with girls and boys each accounting for nearly half. Demirjian's method was used to calculate the patient's chronological age based on their teeth, while hand-wrist x-rays and Fishman's skeletal maturation index were used to calculate the patient's chronological age based on their bones.” Results: We used Spearman's position request connection coefficients to examine the correlation between skeletal and dental maturation. Mean ages of men and women are not fixed at 11.89 1.867 and 12.21 1.473 years, respectively. “Researchers found a strong relationship between chronological age and measures of dental and skeletal maturity (P 0.01). The correlation between dental and skeletal ages was statistically significant (P 0.001), with a connection value of 0.683 for males and 0.704 for women.”

Mandibular growth and morphology are important topics in the field of oral and maxillofacial surgery. For diagnostic and planning purposes, a normative database or statistical shape model of the growing mandible can be of great benefit. A collection of 874 cadaveric children’s mandibles with dental age between 1 and 12 years old were digitized using computed tomography scanning and reconstructed to three-dimensional models. Point correspondence was achieved using iterative closest point and coherent point drift algorithms. Principal component analysis (PCA) was applied to find the main modes of variation in the data set. The average mandible was presented, along with the first ten PCA modes. The first mode explained 78% of the total variance; combining the first ten modes accumulated to 95% of the total variance. The first mode was strongly correlated with age and hence, with natural growth. This is the largest study on three-dimensional mandibular shape and development conducted thus far. The main limitation is that the samples lack information such as gender and cause of death. Clinical application of the model first requires validation with contemporary samples.
