“…Numerous studies have evaluated differences in calcification associated with sex and race with the Demirjian 9 , 36 , 42 , 43 and Cameriere methods 44 , 45 . In the paper presented by Qing et al 36 , no statistically significant differences were observed between men and women, except for tooth 48 in stage E that occurred earlier in women.…”

Currently, human identification is a challenge. Migration due to war, economic crisis or other factors is frequent. The wisdom teeth are the last teeth to initiate and complete development therefore, are fundamental for determining the legal age of majority in different countries. The aim of the study is to determine the validity of two methods based on mineralisation of the third molar to predict the ages of majority of individuals in a Spanish population. Orthopantomographies of 636 men and 750 women (mean age, 16.5 years) were analysed. The Demirjian and Cameriere methods were used, and each tooth was assigned a value according to the degree of mineralisation and maturation. The level of significance used in the analyses was 5% (α = 0.05), with a power of 96.2%. The predictive ability of the Demirjian method to determine 18 years of age in the lower wisdom teeth 93%, respectively. The Cameriere method has a predictive capacity of 88%. There are no statistically significant differences between men and women. Stage H and a cut-off point of 0.08 were the guiding values for determining the age of majority of the study population. For other proposed age ranges (14 and 16 years), both methods were useful in determining the actual age of individuals, with the Demirjian method having a sensitivity of 97.5% with and Cameriere having a predictive capacity of 95%. Both methods can be used with high reliability to determine the age of individuals where reliable documentation is unavailable. Stage H with the Demirjian method and a cut-off point of 0.08 with the Cameriere method can determine the age of majority of the Spanish population. The combination of the two methods does not substantially increase predictive ability.

“…Several studies that have applied the I3M method of Cameriere et al for age estimation in different population have confirmed high levels of sensitivity and specificity for the 0.08 cutoff value in determining adulthood [1][2][3][10][11][12][13][14][15][16][17][18]. In fact, the accuracy of the I3M value of 0.08 has been found to range from a minimum of 72.4% (Saudi Arabia females) 11 to a maximum of 97.6% (Turkish males) [10].…”

Objectives: From an administrative or forensic point of view, the need to estimate the age of living people who do not have hold valid documents is crucial. In this sense 18 years, old cutoff values are of great importance due to civil and criminal imputability in the majority of countries. Different medicine and forensic dentistry methods are used to estimate age. Among them, the development of dental elements is one of the most reliable. This study aimed to apply and discuss sex-specific cutoff 18 years old discriminant ratios advantages over sex-pooled reference value to improve accuracy and specificity over Cameriere et al.’s (2008) method in a Southern Brazilian Sample. Methods: After prior ethical authorization (CAAE: 82403918.0.0000.0075), three experienced examiners measured using Fiji-Image J software, 354 digital panoramic radiographs of individuals aged 14 to 23 years old, to obtain the dental maturity indices (I3m). Based on the sensitivity and specificity criteria (ROC curve), different cutoff values were tested for males and for females. Results: The inter-examiner agreement verified by Intraclass Correlation Coefficient (ICC) was 0.89. Based on post-test results, the 18-year I3m accuracy ranged from 98% to 94% throughout the tested cutoff values, and was 98% for females (I3m =0.09), 96% for males (I3m = 0.07), and 94% for sex-pooled individuals (I3m = 0.08). Sex-pooled sensitivity values where higher when I3m = 0.09, whereas specificity values were higher when I3m = 0.08. Sex-specific cutoff values expressed an increase in female Specificity (+2%) at 0.09 considered the sex-pooled value of 0.08, while best male specificity was observed at 0.08 I3m values. Conclusions: Considering the discriminating objective for estimating the age of 18 years old and its forensic impact, it must be observed the greater importance of the specificity of the test in order to minimize false positives than the overall accuracy. In this sense, we can conclude that even being a forensic reliable option the use of 0.08 sex-pooled I3m ratio, sex specific I3m ratios may be a better option to be used at the local population. Subsequent research on diversified country samples is strongly indicated.

“…Hal ini sesuai dengan beberapa penelitian yang telah dilakukan sebelumnya. 23,24 Namun, hasil ini bertentangan dengan penelitian yang dilakukan oleh Liversidge et al yang melaporkan bahwa pertumbuhan molar ketiga lebih cepat pada wanita dibandingkan pria. Peran jenis kelamin dalam perkembangan molar ketiga hingga saat ini masih belum dipahami seutuhnya.…”

“…Hasil uji ICC pada penelitian ini menunjukkan reliabilitas yang sangat baik meskipun terdapat perbedaan pengalaman dalam melakukan analisis estimasi usia antara HE dan RMB (pengamat pertama dan kedua). Ribier et al 24 melaporkan bahwa metode I3M memperlihatkan reliabilitas intra-rater dan inter-rater yang sangat baik meskipun kedua pengamat baru pertama kali menggunakan metode ini untuk analisis estimasi usia. Dari hal tersebut dapat diketahui bahwa metode I3M memperlihatkan reproduksibilitas yang sangat baik dan bebas dari pengaruh pengalaman pengamat.…”

Up to now, there are still residents of Indonesia who do not have legal documents supporting age information. Hence, proving the age of a person concerning some reasons becomes difficult. Third molar development could be used as an indicator to estimate the age in adolescents if legal documents are not available. This study was aimed to prove the difference in the development of third molars between individuals aged above and below 19 years using the third molar maturity index (I3M) method. Third molar development calculations were performed on 112 digital OPG photographs (71 females and 41 males) of patients aged 16- <24 years. Samples were divided into two age groups, namely <19 years and ≥19 years. We performed comparison tests to analyze the differences between groups and genders against I3M. The results showed significant differences between the development of third molars in individuals aged above and below 19 years according to I3M values. Meanwhile, there was no significant differences in I3M values between males and females. Males experienced faster third molar development than females in the age group <19 years. In conclusion, the I3M method can be used to differentiate the development of third molars in individuals aged above and below 19 years. Further research could be carried out by using a larger number of samples and setting a threshold of I3M for the age of 19 among Indonesian population.Keywords: dental age estimation, third molar, I3M method Abstrak: Pada saat ini, masih ada penduduk Indonesia yang tidak memiliki dokumen legal pendukung informasi usia sehingga terdapat kesulitan dalam membuktikan usia seseorang untuk berbagai kebutuhan. Pertumbuhan molar ketiga dapat digunakan sebagai indikator untuk melakukan estimasi usia pada remaja bila dokumen legal tidak tersedia. Penelitian ini bertujuan untuk membuktikan perbedaan pertumbuhan molar ketiga pada individu berusia di atas dan di bawah 19 tahun dengan metode third molar maturity index (I3M). Perhitungan pertumbuhan molar ketiga dilakukan pada 112 foto OPG digital (71 wanita dan 41 pria) dari pasien berusia 16- <24 tahun. Sampel dibagi menjadi dua kelompok usia, yaitu <19 tahun dan ≥19 tahun. Uji beda dilakukan untuk menganalisis perbedaan antar kelompok dan jenis kelamin terhadap I3M. Hasil penelitian ini menunjukkan perbedaan bermakna antara pertumbuhan molar ketiga pada individu berusia di atas dan di bawah 19 tahun. Tidak terdapat perbedaan bermakna pada nilai I3M pada pria dan wanita. Pria ditemukan mengalami pertumbuhan molar ketiga yang lebih cepat dari wanita pada kelompok usia <19 tahun. Simpulan penelitian ini ialah metode I3M dapat digunakan untuk membedakan pertumbuhan molar ketiga pada individu berusia di atas dan di bawah 19 tahun. Disarankan penelitian lanjut dengan menggunakan jumlah sampel yang lebih besar dan dilakukan penetapan batas ambang I3M untuk usia 19 tahun pada populasi Indonesia.Kata kunci: estimasi usia dental, molar ketiga, metode I3M
