AbstrakEstimasi usia merupakan bagian dari ilmu forensic dan merupakan bagian penting dalam setiap proses identifikasi. Maturasi gigi penting dalam estimasi usia kronologis seseorang. beberapa metode dapat digunakan untuk estimasi usia pada anak. Metode Willems merupakan modifikasi dari metode Demirjian yang menggunakan kalsifikasi mahkota dan akar gigi untuk estimasi usia pada anak. Tujua penelitian ini adalah untuk mengetahui bahwa metode Willems dapat digunakan estimasi usia anak Tionghoa di Surabaya. Sebanyak 76 orthopantomogram yang terdiri dari 32 sampel anak laki-laki dan 44 sampel anak perempuan etni Tionghoa usia antara 6 – 13 tahun telah dianalisa. Metode Willems mengestimasi usia dental melalui penilaiaan terhadap tujuh gigi rahang bawah kiri. Usia kronologis diperoleh dari tanggal lahir anak tersebut.Perbedaan antara usia kronologis dan usia dental dianalisa menggunakan Uji Paired T Test. . Hasil penelitian ini menunjukkan pada laki – laki nilai p= 0,126  (p>0.05), pada perempuan nilai p = 0,053 (p>0.05) dan pada keseluruhan sampel laki-laki dan perempuan nilai p=0.843(p>0.05), hal ini berarti bahwa tidak ada perbedaan signifikan antara usia dental dan usia kronologis.  Kesimpulan dari penelitian ini metode Willems dapat digunakan untuk estimasi usia anak etnis Tionghoa di Surabaya. Kata kunci: estimasi usia, metode Willems, etnis Tionghoa,Surabaya

Objectives: The identification process is very important to determine the identity of the corpse. Identification through teeth is a primary identification method that is often used because teeth have a high degree of individuality. Identification through teeth can be analyzed through dental anomalies. Dental anomalies can assist in the identification process because of their uniqueness, stability, and high incidence in different populations. This paper aims to provide information on the importance of dental anomalies as a relevant and scientific means for identification purposes. Review: Dental anomalies can be defined as morphological abnormalities of the teeth that occur at the stage of growth and development of teeth. Dental anomalies are also inherited disorders that can occur as part of a syndrome. The wide variety of dental abnormalities in the form of size, number, morphology, structure or position of teeth in the oral cavity that can be possessed by each individual can be a characteristic of that individual. Conclusion: The use of dental anomalies in identification has been scientifically recognized with proper diagnosis and writing of dental anomalies in the medical record can be used for identification purposes in the forensic field.

Objectives: Age estimation is an important factor in forensic science and needs to be known accurately because it can narrow the search when examining unidentified victims, determine the victim's age at death and is also useful in cases of adulteration of athletes, child guardianship, or to determine whether someone is of legal age. or not according to the law. This study aims to determine individual age estimates based on the London Atlas and Schour-Massler Atlas and compare the accuracy of the two methods. Materials and Methods: 70 panoramic radiographs consisting of 31 boys and 39 girls from Chinese ethnicity in Surabaya, aged 6-13 years (72-156 months). Samples were determined for dental age based on the London Atlas and the Schour-Massler Atlas. The data that has been obtained is then processed by statistical analysis with SPSS for Windows, with an inclusion level of p <0.05. Results: This study showed that the London Atlas was better and more accurate than the Schour-Massler Atlas with a lower mean error and there was no significant difference between the London Atlas dental age estimation and chronological age with p value = 0.426 in the left region and p = 0.429 in the right region (p>0.05). Conclusion: The results obtained from this study indicate that dental development based on the London Atlas and Schour-Massler Atlas can be used as a method to determine the estimated age of children from the range of 6 - 13 years in ethnic Chinese.

Objectives: Age estimation is a key point in forensics, archeology, pediatrics and pediatric dentistry. Analysis using the development of teeth is one of the available methods that are used for physical identification, as well as age, in children. This article reviewed several journals about the methods of age identification, especially in children. The purpose of this review was to briefly inform about the recent researches regarding the application of age identification methods in children by using panoramic radiography as it is the most widely used method, in the years 2020-2021. Review: This article was a narrative review. Analyzed articles were searched from the PubMed database which were published between 2020 until 2021. There were 12 journals in accordance with the inclusion criteria of age estimation method in children using panoramic radiography. Conclusion: 7 of 12 journals that met the inclusion criteria used Willems method in the researches, 5 journals used Demirjian method, 3 journals used Cameriere method, 2 journals used Nolla method. Willems method was the most used analysis for identifying age and proved to be effective for identification in various populations, such as Belgium, Caucasian, Turkish, Saudi Arabian, Kenyan, Chinese and Taiwanese.
