ABSTRACT
Objective To explore the relationship between cervical bone age and male juvenile mandibular second molar (Msm) root growth ,and to provide evidence for the development of bone and teeth in patients with orthodontic treatment . Methods The CBCT and lateral cephalometric radiographs of 114 cases of 9 .5 to 15 .5 years old children in Chongqing city and ad‐olescents cervical vertebral bone and MSM root length were measured ,using statistical analysis to explore the relationship between cervical vertebral bone ,tooth root length change of age and Msm .Results By Pearson correlation analysis ,Msm root length chan‐ges and cervical vertebral bone were positively correlated(r= 0 .737 ,P< 0 .01) .Msm root length changes showed a positive correla‐tion with age(r= 0 .681 ,P< 0 .01) .Msm root length changes was positively related with dental age(r = 0 .795 ,P< 0 .01) .Conclu‐sion The root growth of the mandibular second molar was highly correlated with cervical vertebral bone in male children .When the growth and development of patients were judged by orthodontic treatment ,we can adopt the mandibular second molar root length forecast growth level of male adolescents .
