"In orthodontics, it is important to assess the skeletal maturity in order to make accurate diagnosis and to plan for appropriate treatment. Evaluation of the skeletal maturity through developmental stages of middle phalanx of the third finger (MP3) and cervical vertebrae (CV) could help in predicting growth acceleration. The methods to evaluate maturity are being developed in order to obtain simple, low radiation and low cost tools for this purpose. The objectives of this study were to identify (1) MP3 maturation stages, (2) CV maturation stages, and (3) agreement between MP3 and CV of 10-16 year-old orthodontic patients. Skeletal maturity of 72 subjects from the Orthodontic Clinic at the Dental Faculty of University of Indonesia was assessed by classifying developmental stages of MP3 as seen in a periapical film and CV as seen on a lateral cephalometric film. MP3 was classified into six stages according to Rajagopal and Kansal method. CV was also classified into six stages as described by Cervical Vertebrae Maturation Index (CVMI). The results showed that (1) at the same chronological age, MP3 and CV maturation stages could vary and the stages follow a gradual chronologic progression; (2) large variation of MP3 maturationstages was found in 12 year-old females (MP3-FG to MP3-I) and in13-14 year-old males (MP3-FG to MP3-HI), (3) large variation ofCV maturation stages was found in 12 year-old females (CVMI 2 to5) and in 12-13 year-old males (CVMI 1, 2, 3 and 5), and (4) anagreement of 70.8% between MP3 and CV maturation stages wasfound in 10-16 year-old orthodontic patients. This study concludedthat besides CVMI, the maturation stages of MP3 could be used as analternative method to assess the skeletal maturity in orthodontics."

"Latar Belakang: Penentuan usia dental dan skeletal sangat penting dalam perawatan ortodonti. Salah satu metode yang dapat digunakan adalah metode Demirjian dan Baccetti. Penelitian sebelumnya menunjukkan bahwa kalsifikasi gigi dapat menjadi salah satu evaluasi usia skeletal. Tujuan: Mengetahui korelasi antara usia dental berdasarkan maturasi gigi dengan usia skeletal berdasarkan maturasi tulang servikal. Metode: Penelitian ini menggunakan metode potong lintang dengan 96 sampel berupa radiograf panoramik dan sefalometri lateral dari satu pasien yang memenuhi kriteria inklusi. Metode Demirjian dan metode Baccetti digunakan untuk mengevaluasi usia dental dan skeletal. Uji korelasi Spearman dilakukan untuk mengetahui korelasi antara usia dental dan skeletal. Hasil: Terdapat korelasi sangat kuat antara skor maturasi gigi dengan maturasi tulang servikal pada laki-laki (r = 0,858, p = 0,000) dan perempuan (r = 0,807, p = 0,000). Korelasi paling kuat pada laki-laki terlihat pada kalsifikasi gigi molar 2 (r = 0,850, p = 0,000), sementara pada perempuan terlihat pada kalsifikasi gigi kaninus (r = 0,805, p = 0,000). Kesimpulan: Korelasi sangat kuat antara usia dental berdasarkan maturasi gigi dan usia skeletal berdasarkan maturasi tulang servikal menunjukkan potensi penggunaan usia dental untuk memperkirakan usia skeletal. Namun, terdapat variasi kekuatan korelasi antar kalsifikasi gigi dengan usia skeletal.

Background: Determining dental and skeletal age is critical in orthodontic treatment. The Demirjian and Baccetti method is one of various approaches to evaluate dental and skeletal age. Related research indicates that tooth calcification can serve as a primary diagnostic tool to determine skeletal age. Objective: To assess the correlation between dental age based on tooth maturation and skeletal age based on cervical vertebrae maturation. Methods: This study involved 96 panoramic and lateral cephalometric radiographs from patients who met inclusion criteria. The Demirjian method was used to assess dental age, while the Baccetti method was used for skeletal age, spearman correlation tests were conducted to evaluate the correlation. Results: A strong correlation was found between tooth maturation scores and cervical vertebrae maturation in males (r = 0,858, p = 0,000) and females (r = 0,807, p = 0,000). In males, the strongest correlation occurred in the second molar (r = 0,850, p = 0,000), while in females it occurred in the canine (r = 0,805, p = 0,000). Conclusion: Dental age based on tooth maturation strongly correlates with skeletal age based on cervical vertebral maturation, suggesting its potential use to estimate skeletal age, but variability exists among tooth types."

Background : Dentocraniofacial structure in children with cleft lip and palate treated with surgical procedures, will affect the growth of the maxilla, but does not affect the structure and position of the mandible. Disproportionate or dentofacial abnormalities can occur when the growth of the maxilla is not in line with the growth of the mandible so as to achieve treatment success should pay attention to the state of growth and development of children, especially in the case of the indicated treatment with surgical orthodontic orthognatic, where surgery is the time when growth has been completed. In the growth stage can be used to identify some indicators such as chronological age, height and weight, the development of teeth and characteristics of sexual maturation that menstruation in women and in men the sound changes. Another indicator is the skeletal development which is generally done through radiographic examination. Determination of skeletal maturation by evaluating marurasi carpal bones, is helpful to establish the diagnosis and appropriate treatment plan.

Objectives : To assess patients with carpal bone maturation stage cleft lip and/or palate aged 15-20 years.

Material and Method : Hand wrist x-ray image of the left hand on 25 sample, result of radiograph performed analysis with Skeletal Maturation Index (SMI). The data was performed statistical analysis chi-squere test.

Results : The results showed carpal bone maturation stage in patients with cleft lip and palate in the age group 15-17 years, are very varied. In the age group 18-20 years, both male and female skeletal maturation stage has been completed. The test result showed statistically differences in skeletal maturation between male and female with cleft lip and palate on Skeletal Maturation Index (SMI).

Conclusion: From this study it can be conclude that there significant differences male skeletal maturation compared to female of children with cleft lip and palate."

"Children development stage is determined by physical growth. The sequence of growing process is usually constant, however the age at which children reach a certain sequence varies individually. Determining skeletal maturation by evaluating carpal bone and cervical vertebrae is very helpful in conducting orthodontic diagnosis and in planning proper treatment. Such evaluation enables to estimate the time of growing process to accelerate or decelerate. The purpose of this study is to evaluate the stage of carpal bone and cervical vertebrae maturation in orthodontic patients at the age of 9 to 18. Samples were 83 cephalograms and hand wrist x-ray from 52 girls and 31 boys. The result of this study showed that the stage of carpal bone and cervical vertebrae maturation in girls and boys in the same age group varies greatly. Girls at the age of 11 to 12 demonstrated highes variation in the stage maturationn. In the same age group of sample, all stages of the maturation indicator were found, such as epiphysis is as wide as diaphysis, the capping of epiphysis, as well as variation in epiphysis fusion. These kinds of variations also occured in the cervical vertebrae maturation stage, where it varies from cervical vertebrae stage 2 to 6. On the other hand, boys showed highest variation at the age of 13 to 14. This study suggests that there was a matching pattern between carpal bone and cervical vertebrae maturation."

"In the past, determination of bone maturity relied on visual evaluation of skeletal development in the hand and wrist, most commonly using the Greulich and Pyle atlas. The Gilsanz and Ratib digital atlas takes advantage of digital imaging and provides a more effective and objective approach to assessment of skeletal maturity. The atlas integrates the key morphological features of ossification in the bones of the hand and wrist and provides idealized, sex- and age-specific images of skeletal development New to this revised second edition is a description and user manual for Bone Age for iPad®, iPhone® and iPod touch®, which can be purchased and used separately from this book. The App can be easily employed to calculate the deviation of the patient’s age from the normal range and to predict a possible growth delay. This easy-to-use atlas and the related App will be invaluable for radiologists, endocrinologists, and pediatricians and also relevant to forensic physicians."

"ABSTRAKLatar Belakang :Maturasi skeletal sangat penting diperhatikan dalam Ilmu Bedah Mulut dan Maksilofasial karena pada beberapa kasus diperlukan maturitas skeletal yang telah selesai untuk penatalaksanaan tindakan bedah. Kasus tersebut antara lain dalam menangani Fibrous dysplasia, tindakan bedah orthognatik dan pemilihan pemakaian jenis plate pada masa pertumbuhan. Maturasi skeletal sangat penting diperhatikan karena apabila tindakan bedah dilakukan sebelum terjadinya maturasi skeletal akan sangat mempengaruhi pertumbuhan dan perkembangan tulang wajah. Maturasi skeletal ini merupakan usia biologis dari manusia dimana antara usia biologis dan usia kronologis belum tentu sama perkembangannya. Penentuan usia skeletal seringkali dilakukan dengan bantuan radiograf tangan dan sefalometri lateral yang menunjukkan adanya korelasi antara pertumbuhan tubuh dengan tulang-tulang wajah. Kedua analisis radiograf ini dapat membantu memberikan petunjuk mengenai usia skeletal seseorang yaitu melalui maturasi skeletal indeks (SMI) dan maturasi vertebra servikalis indeks. Tujuan :Menganalisis apakah ada perbedaan maturasi skeletal antara kelompok ras Proto-Melayu dan Deutro-Melayu melalui analisa maturasi skeletal indeks dan maturasi vertebra servikalis indeks. Bahan dan Cara : Dilakukan pengambilan rontgen foto karpal tangan kiri dan sefalometri lateral pada setiap sampel , hasil radiograf dilakukan tracing tanpa diketahui asal suku dan usia yang kemudian dilakukan analisa dengan maturasi skeletal indeks pada rontgen foto karpal tangan kiri dan maturasi vertebra servikalis indeks pada sefalometri lateral. Dari data yang didapat dilakukan uji statistik chi-square.

ABSTRACTBackground: Skeletal maturation is important to in Oral and Maxillofacial Surgery because in some cases required skeletal maturity has been completed for surgical management. The case is among others in dealing with fibrous dysplasia, and the selection of surgical orthognatik use types during the growth plate. Skeletal maturation is important because if the surgery is performed prior to skeletal maturation would greatly affect the growth and development of facial bones.Skeletal maturation is a biological age of humans in which the biological age and chronological age is not necessarily the same development. Determination of skeletal age is often assessed with hand wrist and sefalometri lateral radiographs showing a correlation between the growth of the body with the bones of the face. Both the analysis of radiographs may help provide a skeletal age is through skeletal maturation index (SMI) and the cervical vertebrae maturation index. Objective: To analyze whether there are any differences in skeletal maturation between Proto-Malay and Deutro-Malay assessed with skeletal maturation index (SMI) and Cervical Vertebrae Maturation Index. Material and Method: Carpal x-ray image of the left hand and sefalometri lateral on each sample, the results of tracing both radiograph performed analysis with Skeletal Maturation Index (SMI) on the left hand carpal x-ray images and the Cervical Vertebrae Maturation Index (CVM) on the lateral sefalometri. The data was performed statistical analysis chi-square test. Results: The test results showed statistically significant differences in skeletal maturation between Proto-Malay and Deutro-Malay on both index , the analysis of skeletal maturation index and the cervical vertebrae maturation index. The Kappa statistical test was perform to see compatibility between SMI and CVM, and the ρ value show the good compatibility between the two indexes. Conclusion: From this study it can be concluded that there were significant differences Protomalay Skeletal Maturation compared with Deutromelayu."

"Perkiraan panjang utuh tulang dari panjang fragmen-fragmennya perlu dilakukan sebagai langkah pertama dalam memperkirakan tinggi badan pada kasus identifikasi atas mayat tak dikenal yang ditemukan dalam keadaan tidak lengkap (kasus mutilasi, berupa bagian-bagian kerangka atau fragmen-fragmen tulang). Penelitian perkiraan panjang utuh tulang dari panjang fragmen-fragmennya pada populasi Indonesia belum pernah dilaporkan, sehingga di lapangan digunakan rumusan yang dibuat berdasarkan penelitian-penelitian pada populasi lain dengan hasil yang kemungkinan kurang tepat. Oleh karena itu, maka dilakukan penelitian analitik-non eksperimental yang bertujuan memperkirakan panjang utuh tulang femur, tibia dan humerus dari panjang fragmen-fragmennya pada populasi Melayu (Deuteromalayid) Indonesia.Pada penelitian ini dilakukan pemeriksaan terhadap 454 tulang yang berasal dari 158 tulang femur (114 pria dan 44 wanita), 125 tulang tibia (90 pria dan 35 wanita), dan 169 tulang humerus (128 pria dan 41 wanita). Pada setiap tulang dilakukan pengukuran terhadap panjang utuh tulang dan panjang fragmen-fragmennya berdasarkan definisi Steel. Kemudian dilakukan analisis mengenai perbedaan panjang utuh tulang dan panjang fragmen-fragmennya serta rasio panjang fragmen-fragmen tulang terhadap panjang utuh tulangnya antara pria dan wanita, dan antara posisi lateral kanan dan kiri dengan uji ANOVA dua jalur, yang dilanjutkan dengan analisis regresi dan faktor multiplikasi untuk mencari hubungan di antara kedua parameter tersebut.Dan hasil analisis tersebut ditemukan bahwa: 1) panjang utuh dan panjang fragmen tulang femur, tibia dan humerus pria lebih panjang daripada wanita, kecuali fragmen T5 dan H3, 2) rasio panjang fragmen-fragmen tulang tibia (T2, T4 dan T5) dan humerus (HI dan H3) pria berbeda dengan wanita, tetapi pada tulang femur rasio tersebut antara pria dan wanita sama; 3) panjang utuh dan panjang fragmen-fragmen tulang femur, tibia dan humerus serta rasio panjang fragmen-fragmen tulang femur, tibia dan humerus kanan sama dengan kiri; 4) persamaan regresi dengan menggunakan prediktor panjang fragmen-fragmen tulang femur, tibia dan humerus layak digunakan untuk memperkirakan panjang utuh tulangnya, kecuali fragmen T1 dan T5 pria dan wanita, dan H3 wanita; 5) faktor multiplikasi fragmen-fragmen tulang femur, tibia dan humerus layak digunakan memperkirakan panjang utuh tulangnya; 6) persamaan regresi lebih tepat dalam memperkirakan panjang utuh tulang femur, tibia dan humerus dan fragmen-fragmennya dibanding faktor multiplikasi, namun secara statistik tidak ditemukan adanya perbedaan yang bermakna.

Estimating Bone Length Of Femur, Tibia And Humerus From The Fragment Length In Indonesian Malay (Deuteromalayid) PopulationEstimating length from its fragment length is required as the first step in estimating stature for identification of incomplete unknown bodies (for example, in mutilation cases and in cases in which only parts of human skeletons or fragmented bone are found). The method for estimating bone length from its fragment length in Indonesian population has not been reported yet. Therefore, in the real case, the estimation of bone length is calculated based on the other population data that usually result on relatively inaccurate result. Based on that reason, an analitic-non-experimental research was executed to get better method for estimating bone length of femur, tibia and humerus from the fragment length in Indonesian Malay (Deuteromalayid) population.The examination was performed on 454 bones that consisted of 158 femur (114 males and 44 females), 125 tibia (90 males and 35 females), and 169 humerus (128 males and 41 females). The measurements of the complete bone lengths and their fragment lengths were based on Steel definition. The analysis of the differences between bone lengths, the fragment lengths and the ratio of the fragmented bone versus the bone length were done between males and females, and between right and left side with two way ANOVA analysis. The analysis was continued with the regression and multiplication factor analysis to find the relationship between these two parameters.The results showed: 1) the male's bone length of femur, tibia and humerus and the fragment length were longer than the female's, except T5 and 1-13 fragments, 2) the male's ratio of the fragmented bones of tibia (T2, T4, and T5) and humerus (HI and H3) to their total length were different from the female's, but for femur, the male's ratio was the same as the female's; 3) the bone length, fragments length and the ratio of the fragmented bone of femur, tibia and humerus on the right side were equal with the left side; 4) regression equations fragment of femur, tibia and humerus can be used for estimating the, bone length, except the male's dan female's T1 and T5 fragments, and the female's H3 fragmen; 5) multiplication factor of fragmented bone of femur, tibia and humerus can be used for estimating the bone length; 6) regression equation is more precise than multiplication factor in estimating the bone length from the fragment length, although, statisticaly, there are no significant differences."
