Relationships between Cervical Vertebral Bone Ages, Dental Ages and Chronological Ages Among Children
Objective: To investigate the relationship between cervical bone age, dental age and age in children, and to provide a basis for orthodontic clinical diagnosis and the development of treatment plans. Methods: The age of cervical vertebrae and the degree of calcification of the left mandibular second molar were evaluated by digital lateral cephalometric films and oral surface tomo-grams in 210 children aged 8～16 years, and correlation analyses were used to analyze the relationship between the age of cervical vertebrae, the degree of calcification of the mandibular second molar, and age. Results: Cervical vertebral bone ages and chronological ages had medium relationship (r=0.665, P<0.05);There were statistical differences between males and females in CS3, CS4, and CS5 stages, and chronological age was mostly between 12 and 14 years old; mandibular second molar calcification and chronological ages had significant relationship (r=0. 925, P<0. 05). With increasing age, the calcification of children' s teeth gradually increased. Conclusion: Cervical bone age and the level of calcification of the mandibular second molar in children correlate with age. The use of cervical bone age in orthodontic treatment to assess the level of growth and development in children is reliable.
