Demirjian approach of dental age estimation: Abridged for operator ease

Abstract

Background:Present times have seen an alarming increase in incidence of crimes by juveniles and of mass destruction that Highlight the preponderance of individual age estimation. Of the numerous techniques employed for age assessment, dental age estimation (DAE) and its correlation with chronological age (CA) have been of great significance in the recent past. Demirjian system, considered as gold standard in DAE is a simple and convenient method for DAE, though,, although, referring to multiple tables make it cumbersome and less eco friendly due to excessive paper load.Aim:The present study was aimed to develop a comprehensive chart (DAEcc) inclusive of all Demirjian tables and developmental stages of teeth and also to as well as to test the operator ease of 50 undergraduate dental students in performing DAE using this chart.Materials and Methods:The study was performed in two stages, wherein the first stage was aimed at formulation of the comprehensive chart (DAECC) which included pictorial representation of calcification stages, the Federation Dentaire Internationale notation of the teeth, and the corresponding scores for each stage with a concluding column at the end to enter the total score. The second stage assessed the applicability of the ease of DAE by DAECC, whereby fifty 2nd year BDS students were asked to trace the calcification stages of the seven permanent left mandibular teeth on a panorex, identify the correct stage, assign the corresponding score, and to calculate the total score for subsequent dental age assessment.Results and Conclusions:showed that average time taken by the students for tracing seven mandibular teeth was 5 min and for assessment of dental age was 7 min. The total time taken for DAE was approximately 12 min, thus making the procedure less time consuming. Hence, this study proposes the use of DAEcc for age estimation due to ease in comprehension and execution of Demirjian system.

Tiempo Empleado para Estimar Edad Dental en Niños Peruanos Comparando el Método de Demirjian y el Cuadro Integral del Enfoque de Demirjian: Un Estudio Piloto

“…A pesar de que el método de Demirjian es un estándar tradicional por excelencia (Fonseca et al, 2015;Cummaudo et al, 2021), se han reportado sobrestimaciones o subestimaciones en las diferentes poblaciones estudiadas. Esto justifica el ajuste de las tablas originales de puntuación, o el uso complementario con el análisis óseo, ambas con el fin de aumentar la certeza del resultado de las estimaciones de ED (Jain et al, 2016;Kapoor & Jain, 2018).…”

“…Se ha mencionado que la experiencia profesional influye en la confiabilidad del método de estimación de ED, requiriendo capacitación y práctica (Franceschetti et al, 2022) pero también el avance tecnológico y el enfoque matemático (Ubelaker & Khosrowshahi, 2019). La eficiencia del análisis fue motivo para la formulación de un "cuadro completo para estimación de la edad dental" (DAEcc en su acrónimo original), el cual facilitó el manejo del operador logrando la interpretación en 12 minutos según la modificación de Demirjian (Jain et al, 2016) y de 7 minutos según la modificación de Chaillet y Demirjian (Kapoor & Jain, 2018).…”

Characteristics of the Gingival Epithelium of Children’s Third Molars at Different Stages of Root Formation

“…The clinical examination of the children was carried out using conventional methods. Radiographic assessment of the condition of the third molar ridges was performed according to the Demirjian method [21], which is currently widely used internationally [22,23]. Clinically and radiographically, three observation groups were identifi ed: I (n=30) -children aged 11-13 years whose third molar was at the stage of weakly mineralized rudiment (Demirjian stage D); II (n=35) -children aged 13-16 years whose third molar was at the stage of mineralized rudiment and the initial stages of root formation (Demirjian stages E and F) and III (n=30)children aged 16-18 years whose third molar was at the fi nal stages of root formation (Demirjian stages G and H).…”

Age Estimation by Modified Demirjian’s Method in a Hospital-Based Population: A Radiographic Study

“…Its applicability is tremendous in rural areas where the awareness of childbirth registration and recordkeeping is bare minimal. Apart from this, instances of serious crimes committed by juveniles, intentional manipulation of the definite date of birth for procuring jobs, selections in sports and higher education have increased the need for accurate chronological age estimation methods for legal considerations and forensic science [1].…”
