“…However, this method has a limitation that there is no separate diagram based on gender differences, and there are gaps in the order of age categories. 3 A study conducted by Jurca et al in 2014 in Romania stated that the Demirjian method can be used for age estimation analysis. 7 The Demirjian method has results that are almost accurate or the same as the chronological age, because the analysis of the Demirjian method is carried out on the maturity of the dental age which has detailed scores and separate assessments between men and women.…”

“…Therefore, teeth can provide information about an individual's identity because of its distinctive characteristics, especially information about age estimation. 2,3 Based on experience, teeth have a high contribution in determining a person's identity. In October 2002 Bali Bomb case, around 50% of victims could be identified based on their teeth.…”

“…The results of the study showed that there was no statistically significant difference between chronological age and dental age with the Schour-Massler method assessment. 3 The same study in 2018 at Rajasthan was conducted by Mankel et al (estimated dental age) using the Demirjian method by choosing 7 mandibular left teeth and compared to the Modified Demirjian method by using 8 mandibular left teeth. The total of research subjects were 431 people consisting of ages 6-18 years, 219 people were males and 212 people were females.…”

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.

“…Schour-Massler (1941) menjelaskan bahwa estimasi usia dental terbagi dalam 21 tahap perkembangan dan melibatkan gigi sulung serta gigi geligi di rahang atas serta rahang bawah. Kendala pada metode Schour-Massler yaitu pada bagan perkembangan gigi tidak terdapat perbedaan antara jenis kelamin laki-laki dan wanita, 4 Al-Qahtani menjelaskan perkembangan gigi dan tingkat erupsinya pada satu regio di rahang atas dan satu regio rahang bawah pada setiap individu dengan rentang usia 6-23 tahun. Kendala pada metode Al-Qahtani yaitu diagram metode Al-Qahtani hanya dilihat berdasarkan perkembangan gigi molar ke-dua dan ke-tiga saja, sehingga dapat memengaruhi hasil usia dari penelitian yang disebabkan oleh keadaan perkembangan gigi molar ke-tiga yang berbeda-beda.…”

Unexpected incident such as natural disaster and accident often occur in many countries including Indonesia which causes many victims with unknown identity. Tooth is one of the indicators to assess and determine a person's identity. Blenkin-Taylor method is used for age estimation of an individual by using teeth. This study was aimed to obtain the estimation of biological age by using Blenkin-Taylor method in Semarang. This was a descriptive study with a cross sectional design. Samples were panoramic digital radiograph data of patients aged 5-15 years, copied in the form of a soft file. The observation and measurement were performed on seven teeth of right lower jaw by using the DICOM RadiAnt application. Data of observations and measurements of maturation scores were calculated and converted into the Blenkin-Taylor formula to determine the biological age. The results showed that the difference between biological and chronological age was ±0.32 years. This value was lower than the Blenkin-Taylor previous study result which was ±0,6 years. In conclusion, by using the Blenkin-Taylor method, there was a difference between biological age and chronological age as many as ±0,32 years in individuals aged 5-15 years old in Semarang.Keywords: biological age, the Blenkin-Taylor method, panoramic radiography Abstrak: Kejadian tidak terduga seperti bencana alam dan kecelakaan sering terjadi di berbagai negara, salah satunya di Indonesia yang menimbulkan banyak korban jiwa yang tidak diketahui identitasnya. Gigi merupakan salah satu indikator untuk menilai dan menentukan identitas seseorang. Salah satu metode dalam menentukan estimasi usia dengan menggunakan gigi ialah metode Blenkin-Taylor. Penelitian ini bertujuan untuk mendapatkan gambaran estimasi usia biologis dengan menggunakan metode Blenkin-Taylor di Kota Semarang. Jenis penelitian ialah deskriptif dengan desain potong lintang. Sampel penelitian ialah data file digital radiograf panoramik pasien berusia 5-15 tahun yang disalin ke dalam bentuk soft file, kemudian dilakukan pengamatan dan pengukuran pada 7 gigi regio kanan rahang bawah dengan menggunakan aplikasi RadiAnt DICOM. Hasil pengamatan dan pengukuran skor maturasi dihitung dan dikonversikan ke dalam rumus metode Blenkin-Taylor untuk menentukan usia biologis. Hasil penelitian menunjukkan bahwa selisih usia biologis dan usia kronologis sebesar 0,32 tahun. Hal ini lebih kecil dibandingkan penelitian Blenkin-Taylor terdahulu sebesar 0,6 tahun. Simpulan penelitian ini ialah dengan mengggunakan metode Blenkin-Taylor terdapat selisih rerata usia kronologis dan usia biologis sebesar ± 0,32 tahun pada individu usia 5-15 tahun di Kota Semarang.Kata kunci: usia biologis, metode Blenkin-Taylor, radiograf panoramik

Indonesia is an archipelagic country bordered by tectonically active zones with intense seismicity and volcanism. This condition is often associated with a high-risk situation of disasters in Indonesia. Forensic identification is a necessary procedure to reveal an individual’s identity. An identity, including sex and age, is needed to build a conclusion of human identification. Dental age estimation is a subfield of forensic odontology which focuses on establishing an individual’s age. Tooth development, biochemical, and postformation changes are the parameters for estimating dental age. This review discusses the applicable dental age estimation method for children and adolescents in Indonesia. Several articles that have previously studied dental age estimation in Indonesia were reviewed for this manuscript. On reviewing these articles, it was found that the Demirjian method, the Willems method, and the Al Qahtani method are useful in this population with higher accuracy than other methods.
