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.
