Differences chronological age and dental age using Demirjian method based upon a study radiology using radiography panoramic at the Dental Hospital Hasanuddin University

Abstract

Background.Choronological age is assessed by the date, month, and year of birth. Several researches suggested that Chronological age may not be able to provide sufficient information regarding on human growth precisely. Chronological age, on the other hand, could not be used to assess Maturity development rate of a patient, so it is necessary to assess the dental age. Dental age is age assessment method by measuring human growth and development. Age estimation has important role in health field, Particularly in dentistry as it will be beneficial in making appropriate diagnosis, Treatment plan, and prognosis. Tooth eruption estimation according to Demirjian Method conducted by assessing growth and development process of tooth using panoramic radiography. Purpose. Determine the difference between Chronological Age and Dental Age Using Demirjian Method Based on Radiology Analysis of Panoramic Radiography. Method. This study was an observational analytic using Cross-sectional study, all data are observed once at the time. In this study, the amount of sample reviewed were 30 samples, consisted of 4 – 9 years old children. Panoramic radiography were collected based on target population which fulfill Sample Criteria from reconciled patient of radiology department RSGM Unhas. The results were obtained by estimating the score of dental age using Demirjian Method. After that, the Dental age and chronological age were analayzed to obtain the mean difference. Result. Based on wilcoxon test, mean value was obtain p:0.011 (p<0.05), this result shows that there is significant difference between chronological age and dental age. Conclusion.Chronological age and dental age can be assessed by reviewing the panoramic radiography using Demirjian Method

Age Estimation in 0–8-Year-Old Children in France: Comparison of One Skeletal and Five Dental Methods

“…In a French study, Demirjian’s method was found to overestimate age by 1.17 years when applied to children aged 6.0–11.5 years old [ 39 ]. In addition, Yunus and Wardhani examined 30 panoramic radiograph samples of Indonesian children aged 4–9 years old using the Demirjian method [ 40 ]. The results showed low accuracy because of significant overestimation of dental age compared with the chronological age.…”

Estimation Of Dental Age Using Coronal Pulp Cavity Index (CPCI) On Lower Second Premolar And First Molar With Periapical Radiographic Analysis

“…(Veera et al, 2014) Previous studies reported the assessment of chronological and dental age based on panoramic radiography. (Godge et al, 2014;Yunus and Wardhani, 2016) Meanwhile, the estimation of dental age can identiied using CPCI method, which is calculated through the correlation between the reduction of the coronal pulp cavity and the chronologicalage.Lower premolars and molars wereconsidered in this method, as the mandibular teeth are more visiblethan the maxillary ones. (Priyadarshini et al, 2015;Putri et al, 2013) The youngest sample of this study aged 21 years and the oldest age of the group is 30 years with the proportion of male and female is the same 50% (n = 30) as described in Tables 1 and 2.…”

The Applicable Dental Age Estimation Methods for Children and Adolescents in Indonesia

“…In the study by Yunus and Wardhani in 2016, 30 panoramic radiograph samples of Indonesian children between 4–9 years old were calculated using the Demirjian method. The result showed that the Demirjian method is less accurate because there is a significant overestimation of dental age compared with the chronological age [ 22 ].…”
