Summary
The cervical vertebrae maturation method (CVMM) showed similar reproducibility regardless of orthodontic experience. Interestingly, clinicians with less experience demonstrated better performance in assessing skeletal maturity using CVMM.
Area of Science:
- Orthodontics
- Dental Radiology
- Skeletal Age Assessment
Background:
- The cervical vertebrae maturation method (CVMM) is widely used in orthodontics to assess skeletal maturity.
- Accurate assessment of skeletal maturity is crucial for treatment planning in orthodontics.
Purpose of the Study:
- To evaluate the interobserver and intraobserver reproducibility of the CVMM.
- To determine if orthodontic experience influences the reproducibility of CVMM assessments.
Main Methods:
- Fifty lateral cephalograms were assessed by 30 clinicians with varying orthodontic experience (≤1 year, 2-4 years, ≥7 years).
- Assessments were conducted in two sessions, 3 weeks apart, using Kendall's W and Cohen's kappa coefficients.
- Percentage of perfect agreement (PPA) and disagreement stages were calculated.
Main Results:
- The junior group (≤1 year OE) showed the highest interobserver agreement (Kendall's W = 0.87 at T1, 0.86 at T2) and Cohen's kappa (κ = 0.78).
- Overall interobserver perfect agreement was 42.3% (T1) and 46.3% (T2).
- Intraobserver perfect agreement was 54.2%.
Conclusions:
- Orthodontic experience did not enhance the reproducibility of the CVMM.
- Clinicians with less orthodontic experience exhibited superior performance in applying the CVMM.

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

The vertebral column or spine is a flexible column that supports the head, neck, and body and allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...
