Latar Belakang: Di Indonesia penelitian mengenai Korelasi Maturasi Antara Vertebra Servikalis Baccetti dan Molar Dua Permanen Bawah Demirjian pada Anak Usia 8-16 Tahun belum banyak dipublikasikan. Tujuan: mengevaluasi Korelasi Maturasi Antara Vertebra Servikalis Baccetti dengan Molar Dua Permanen Bawah Demirjian pada anak usia 8-16 tahun. Metode: Penelitian deskriptif analisis ini dilakukan dengan menggunakan studi crosssectional. Sampel diperoleh dari 90 radiograf panoramik dan sefalometri lateral dari anak yang berusia 8-16 tahun dengan kriteria tertentu. Maturasi dental diperiksa melalui tahap mineralisasi Molar Dua Permanen Bawah berdasarkan metode Demirjian (tahap A-H); Maturasi Skeletal dievaluasi dengan menggunakan metode Maturasi Vertebra Servikalis berdasarkan metode Baccetti (CS1-CS6). Uji reliabilitas penelitian menggunakan uji statistik Kappa. Uji Kendall Tau-b digunakan untuk menentukan korelasi antara Maturasi Vertebra Servikalis dan Molar Dua Permanen Bawah. Hasil: Tahap CS1 memiliki distribusi paling banyak tahap D; CS2 memiliki distribusi paling banyak tahap E; pada CS3 memiliki distribusi yang merata pada tahap F dan G, CS4 memiliki distribusi paling banyak tahap G, CS5 memiliki distribusi yang hampir merata pada tahap G dan H; dan tahap CS6 memiliki distribusi paling banyak pada tahap H. Korelasi antara Maturasi Vertebra Servikalis dan Molar Dua Permanen Bawah sangat kuat dan signifikan (r = 0,829; p <0,05). Kesimpulan: Molar Dua Permanen Bawah dapat dipertimbangkan sebagai indikator maturasi skeletal pada anak usia 8-16 tahun. ......Background: In Indonesia, the research on Correlation Between the Maturation of Cervical Vertebral and Lower Permanent Second Molar in Children Aged 8-16 Years has not been widely publicized. Objective: to evaluate the correlation between the Maturation of Cervical Vertebral of the Baccetti method and lower permanent second Molar of the Demirjian method in children aged 8-16 years. Method: This research was conducted using a cross-sectional study. Samples were obtained from 90 panoramic radiographs and lateral cephalometry obtained from children ages 8-16 years with certain criteria. Maturation of teeth was examined through the mineralization stage of the Lower Permanent Second Molar based on the Demirjian method (stage A-H). Skeletal Maturation was evaluated by the use of the Cervical Vertebral Maturation method based on Baccetti (Stage CS1-CS6). The reliability test uses the Kappa statistical test. Kendall Tau-b Test was used to determine the correlation between the maturation od Cervical Vertebral and Lower Permanent Second Molar. Results: Stage CS1 has the most distribution of stage D; CS2 has the most distribution of stage E; in CS3 has equal distribution of stage F and G; in CS4 has the most distribution of stage G; in CS5 has equal distribution of stage G and H; and stage CS6 is has the most distribution of stage H. The correlation between Cervical Vertebral Maturation and Lower Permanent Second Molar Maturation was very strong and significant (r = 0.829; p <0.05). Conclusion: The Lower Permanent Second Molar can be considered as indicator of skeletal maturation in children aged 8-16 years.

Indonesian Journal of Dentistry 2006; Edisi Khusus KPPIKG XIV: 134-138 One of the growth indicators that can be used to assess a child's developmental growth is through skeletal maturation. Skeletal maturity can be evaluated by using anatomical changes of the cervical vertebral bones observed on the lateral cephalometric radiographs. The purpose of this study was to determine the stage of cervical vertebrae maturation of Hb E B thalassemia patients by comparing the shape changes of the second to fourth cervical vertebrae bodies with a control group. The design of this study was a cross sectional. The subjects were children with Hb E B thalassemia aged 9-14 years. The results showed that the retarded maturation of the cervical vertebrae in Hb E B thalassemia was not found in subjects of pre-puberty age (9-11 years old), but in those of puberty age (12-14 years old).;One of the growth indicators that can be used to assess a child's developmental growth is through skeletal maturation.

Penelitian ini merupakan penelitian potong lintang yang bertujuan untuk menganalisis korelasi antara cervical vertebral maturation dengan dimensi mandibula. Data berasal dari 90 radiograf sefalometri lateral (49 perempuan, 41 laki-laki), anak usia 8-16 tahun di Jakarta. Metode: menggunakan penilaian dan pengukuran visual radiograf sefalometri lateral, dimensi mandibula diukur berdasarkan panjang total mandibula (jarak dari titik condylon - gnathion), tinggi ramus mandibula (jarak dari titik condylon - gonion intersection), dan panjang corpus mandibula (jarak dari titik gnathion - gonion intersection), selama tahap maturasi skeletal vertebra servikalis (cervical stage 1 sampai cervical stage 6) yang dinilai dari badan kedua sampai badan keempat tulang vertebra servikalis. Korelasi antara cervical vertebral maturation dengan dimensi mandibula dianalisis menggunakan uji Spearman. Hasil: terdapat korelasi yang kuat dan signifikan (p < 0,05) antara cervical vertebral maturation tahap pubertas dengan panjang total mandibula (r = 0,663), antara cervical vertebral maturation tahap pubertas dengan tinggi ramus mandibula (r = 0,555), dan antara cervical vertebral maturation tahap pubertas dengan panjang corpus mandibula (r = 0,510). Terdapat korelasi yang sedang dan signifikan (p < 0,05) antara cervical vertebral maturation tahap prepubertas dengan panjang total mandibula (r = 0,453), antara cervical vertebral maturation tahap prepubertas dengan tinggi ramus mandibula (r = 0,395), dan antara cervical vertebral maturation tahap pascapubertas dengan panjang corpus mandibula (r = 0,374). Kesimpulan: terdapat korelasi antara cervical vertebral maturation dengan dimensi mandibula terutama pada tahap pubertas. Maturasi skeletal dapat digunakan untuk menilai pertumbuhan dan perkembangan mandibula, sebagai pertimbangan dalam mengoptimalisasi waktu perawatan ortopedik maksilofasial. ......This study is a cross-sectional and aims to analyze correlation between cervical vertebral maturation and mandibular dimensions from 90 lateral cephalometric radiograph (49 girls, 41 boys), aged 8-16 years in Jakarta. Methods: The method uses visual measurements of lateral cephalometric radiograph, mandibular dimensions were assessed from total mandibular length (range of condylon - gnathion line), ramus mandibular height (range of condylon - gonion intersection line), and corpus mandibular length (range of gonion intersection – gnathion line), during maturity stages of the cervical vertebral bone (cervical stage 1 to cervical stage 6) which assessed from second to fourth branches. Correlation between cervical vertebral maturation and mandibular dimensions were analyzed using Spearman method. Results: The results showed a significant (p < 0.05) and strong correlation between cervical vertebral maturation pubertal stage and total mandibular length (r = 0.663), between cervical vertebral maturation pubertal stage and ramus mandibular height (r = 0.555), and between cervical vertebral maturation pubertal stage and corpus mandibular length (r = 0.510). The results showed a significant (p < 0.05) and medium correlation between cervical vertebral maturation prepubertal stage and total mandibular length (r = 0.453), between cervical vertebral maturation prepubertal stage and ramus mandibular height (r = 0.395), and between cervical vertebral maturation post pubertal stage and corpus mandibular length (r = 0.374). Conclusion: The Correlation between cervical vertebral maturation and mandibular dimension is seen mainly in puberty stage. Skeletal maturity used to assess mandibular growth for optimization maxillofacial orthopaedic treatment timing.
