Introduction. Dental age apart from skeletal age is an important factor in the estimation of biological age of patients. Its evaluation is crucial in making decisions concerning diagnostic algorithms and treatment options in such fields of medicine as paedodontics, conservative dentistry, orthodontics, paediatrics or endocrinology as well as for forensic purposes. There are various methods of radiological dental age estimation and their validity is related to the studied population. Aim. The aim of the paper is to estimate dental age by means of two radiological methods based on panoramic radiographs, i.e. the original method by Cameriere and the modified European formula. Material and methods. The material consisted of 2148 digital radiographs taken in patients of both genders, aged from 5 to 15 years, with visible germs of all permanent teeth, apart from third molars. Two methods by Cameriere were applied – the original one and the European formula. Statistical analysis was performed. Results. Dental age obtained by means of the two Cameriere’s methods was significantly different from chronological age (Wilcoxon’s test, p < 0.001). However, in the case of the original method the mean dental age was lower than the chronological one, while the European formula led to the overestimation of dental age. Conclusions. The European formula is more suitable for the evaluation of the Polish population than the original method by Cameriere.

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).

Abstract For medicolegal purposes, orthodontic or orthognathic treatment various stomatological staging technique for age estimation with appliance of conventional radiographic images have been published. It remains uninvestigated if cone beam computer-tomography delivers comparable staging results to the conventional radiographic stages of third molar analysis.We conducted a retrospective cross-sectional study of 312 patients aged 13 to 21 years. Dental age estimation staging technique, introduced by Nolla and Demirjian, were applied on the left lower third molar imaged by conventional panoramic radiographs and cone beam computer-tomography. It was investigated if 2D and 3D imaging presented different staging results for dental age estimation.In 21% the Demirjian’s staging differed by a single stage between 2D and 3D images. The greatest congruence (87%) between 2D and 3D images was revealed for stage 7 (G). In contrary, stage 5 (E) presented the lowest level of congruence with 47.4%. The categorization of Nolla revealed divergences in staging for than 2 categorical variables in Nolla’s stages 3,4,5 and 6. In general, the analysis of the data displayed the divergence for Nolla’s stages 4 to 8. The staging results for 2D and 3D imaging in accordance to the rules of Nolla and Demirjian showed significant differences. Individuals of 18 years may present immature third molars, thus merely an immature third molar cannot reject legal majority.Nolla’s and Demirjian’s 2D and 3D imaging present significantly different staging results.
