"Indonesian Journal of Dentistry 2006; Edisi Khusus KPPIKG XIV: 134-138One 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.

"Latar Belakang: Di Indonesia penelitian mengenai Korelasi Maturasi Antara VertebraServikalis Baccetti dan Molar Dua Permanen Bawah Demirjian pada Anak Usia 8-16Tahun belum banyak dipublikasikan.Tujuan: mengevaluasi Korelasi Maturasi Antara Vertebra Servikalis Baccetti denganMolar 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 anakyang berusia 8-16 tahun dengan kriteria tertentu. Maturasi dental diperiksa melalui tahapmineralisasi Molar Dua Permanen Bawah berdasarkan metode Demirjian (tahap A-H);Maturasi Skeletal dievaluasi dengan menggunakan metode Maturasi Vertebra Servikalisberdasarkan metode Baccetti (CS1-CS6). Uji reliabilitas penelitian menggunakan ujistatistik Kappa. Uji Kendall Tau-b digunakan untuk menentukan korelasi antara MaturasiVertebra Servikalis dan Molar Dua Permanen Bawah.Hasil: Tahap CS1 memiliki distribusi paling banyak tahap D; CS2 memiliki distribusipaling 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 hampirmerata pada tahap G dan H; dan tahap CS6 memiliki distribusi paling banyak pada tahapH. Korelasi antara Maturasi Vertebra Servikalis dan Molar Dua Permanen Bawah sangatkuat dan signifikan (r = 0,829; p <0,05).Kesimpulan: Molar Dua Permanen Bawah dapat dipertimbangkan sebagai indikatormaturasi 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."

"Penelitian ini merupakan penelitian potong lintang yang bertujuan untuk menganalisiskorelasi antara cervical vertebral maturation dengan dimensi mandibula. Data berasaldari 90 radiograf sefalometri lateral (49 perempuan, 41 laki-laki), anak usia 8-16 tahun diJakarta. Metode: menggunakan penilaian dan pengukuran visual radiograf sefalometrilateral, dimensi mandibula diukur berdasarkan panjang total mandibula (jarak dari titikcondylon - gnathion), tinggi ramus mandibula (jarak dari titik condylon - gonionintersection), dan panjang corpus mandibula (jarak dari titik gnathion - gonionintersection), selama tahap maturasi skeletal vertebra servikalis (cervical stage 1 sampaicervical stage 6) yang dinilai dari badan kedua sampai badan keempat tulang vertebraservikalis. Korelasi antara cervical vertebral maturation dengan dimensi mandibuladianalisis menggunakan uji Spearman. Hasil: terdapat korelasi yang kuat dan signifikan(p < 0,05) antara cervical vertebral maturation tahap pubertas dengan panjang totalmandibula (r = 0,663), antara cervical vertebral maturation tahap pubertas dengan tinggiramus mandibula (r = 0,555), dan antara cervical vertebral maturation tahap pubertasdengan panjang corpus mandibula (r = 0,510). Terdapat korelasi yang sedang dansignifikan (p < 0,05) antara cervical vertebral maturation tahap prepubertas denganpanjang total mandibula (r = 0,453), antara cervical vertebral maturation tahapprepubertas dengan tinggi ramus mandibula (r = 0,395), dan antara cervical vertebralmaturation tahap pascapubertas dengan panjang corpus mandibula (r = 0,374).Kesimpulan: terdapat korelasi antara cervical vertebral maturation dengan dimensimandibula terutama pada tahap pubertas. Maturasi skeletal dapat digunakan untukmenilai pertumbuhan dan perkembangan mandibula, sebagai pertimbangan dalammengoptimalisasi 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."
