Schour-Massler and Demirjian are methods used to estimate chronological age in dental radiographs by looking at the development of permanent teeth and the maturity of the dental age. Chronological age is based on date of birth. Dental age is the age based on the maturity of the teeth. Both of these methods have been widely used in previous studies, but have never been compared. The purpose of this study was to determine whether there are differences in age estimation using the Schour-Massler and Demirjian methods. This study was an observational analytic study with a cross sectional design. The research sample was 46 patients who came to USU General Hospital at the age of 10-16 years. This research was consist at the Radiology Unit of the Faculty of Dentistry, University of North Sumatra. The results of this study indicate the p value of the Wilcoxon test results with the p value for Schour-Massler p=0.090 > 0.05 and Demirjian p=1,000. Both p values> 0.05, there is no significant difference in assessing the estimated age using both methods, so Ha is accepted. In conclusion, the Schour-Massler and Demirjian methods provide estimates of age that are close to actual age, so there is no significant difference between the two methods.

“…The tooth stages are described in Table 1. 16,17 Radiographs of each problematic tooth were obtained, with the use of Planmeca ProX (Planmeca) device, by the paralleling technique, which helps measure relative objective size parameters of the tooth. The proposed modified approach for improving the assessment of tooth development stage according to the radiological features involves taking digital radiographs of teeth, unification of tooth parameters by indicators of the standardized area of interest and plane orientation, contrast optimization and segmentation of the graphic image of the tooth, adaptation of object dimensional parameters to similarities in the reference graphical representations of Demirjian et al's stages of tooth development, 16 and further enhance the comparison by superimposition with the software MATLAB (The MathWorks, Inc., Natick, Mass.).…”

“…Forensic dental approaches such as those of Haavikko 32 or Demirjian et al 16 provide algorithms for categorizing tooth development stages that were traditionally estimated according to dental status. [16][17][18][19][20] It used to be difficult to justify implementing those approaches in clinical practice. Moreover, most clinicians disregard the difference between the chronological and dental ages of pediatric patients, but this difference plays a significant role in the choice between different treatment modalities.…”

Clinicians have previously reported effective outcomes of apexification in cases of complicated caries or trauma; however, there is still not enough evidence of how root development stage before treatment influences the success of this procedure. Objectives: The study was performed to evaluate the influence of pretreatment root development stage on the success of apexification, with the use of a modified forensic technique for estimating odontologic age. Methods: Apexification of maxillary and mandibular permanent incisors, first molars, and premolars was provided to 43 pediatric patients with symptoms of irreversible pulp changes or signs of chronic apical periodontitis. Success of apexification was evaluated with the use of a modification of Demirjian et al.'s age estimation technique; root development stages were documented radiologically before and 12 months after treatment. Results: There was a close covariance between pretreatment tooth development stages F and G and the possibility of achieving stage H after apexification (rs = 0.87 and 0.91, respectively; p < 0.05) with an average follow-up period of 11.6 ± 0.7 months. Conclusion: Pretreatment tooth development at stages F to H, as originally proposed by Demirjian et al., was found to significantly influence the prognosis for achieving successful apexification outcome.
