Abstract
The evaluation of the bone maturation is very important for the orthodontic diagnostic and treatment plan and many places of the body can be utilized for this goal. The aim of this study was to verify the correlation between hand-wrist and cervical maturation stages of skeletal maturation. Lateral cephalometrics and hand wrist radiographs were made. The Hassel and Farm method was used for the cervical vertebras and Singer simplified method for the hand wrist radiographs. About 60 patients formed the sample with ages ranging between 7 and 14 years. From this total, 30 were male and 30 female. Spearman’s (r1) and Kendall’s (r2) coefficients were used to establish the correlation among the 6 stages presented by the two methods. The male group’s results were r1= 0.680 and r2= 0.656, the female group’s were r1= 0.666 and r2= 0.634 and the whole sample’s were r1= 0.743 and r2= 0.696. All the results showed a high correlation, statistically significant (p≤ 0.001). There was a significant correlation among maturation stages presented by both methods. The radiograph evaluation of the cervical vertebras is an alternative parameter which is practical and completes the range of information that can be obtained from cephalometric radiographs and it can, circumstantially, replace other method for evaluation, further on decreasing the additional x-ray exposition.

AbstrAct evaluation of bone maturation is highly important for orthodontics planning and treatment. various parts of the body can be used for that purpose. the objective of the research was to check the correlation between the bone maturation stages of the cervical vertebrae and the bone maturation stages found at the hand-wrist region. lateral X-rays were taken . hand and wrist X-rays were obtained. the hassel and farman method was used for the cervical vertebrae and the simplified Singer method was used for hand and wrist
The sample was compounded of 60 patients from the orthodontics clinic, FO-UERJ, 30 males and 30 females, ages between 7 and 14
Summary
The objective of the research was to check the correlation between the bone maturation stages of the cervical vertebrae and the bone maturation stages found at the hand-wrist region. The study revealed a high correlation between the stages for both methods, for males (r1= 0.608 and r2= 0.656) and females (r1= 0.666 and r2= 0.634) and for the total sample (r1= 0.743 and r2= 0.696). The conclusion was that the lateral X-ray evaluation of morphological alterations of hand-wrist vertebrae is trustworthy and practical for bone evaluation since it has a high correlation with a method that is already commonly used. Determining residual growth is an important factor in orthodontic treatment. Several areas of the body may be used to analyze ossification centers, such as foot, elbow, knee, cervical vertebrae, hip, pelvis and skull. The hand- wrist region is the most used one because it has a great number of ossification centers in a relatively small area [2, 11]
