Correlation between spheno-occipital synchondrosis, dental age, chronological age and cervical vertebrae maturation in Turkish population: is there a link?

Objective: To assess the correlation between third molar mineralization (TMM), spheno-occipital synchondrosis (SOS) fusion, chronologic age and cervical vertebrae maturation (CVM) for skeletal maturation. Materials and methods: Radiographs for 116 patients between 8 and 28 years were evaluated for age determination using mandibular TMM, SOS fusion and CVM. Spearman Correlation and Kappa test analyses were used to assess the relationship between variables and for intraobserver reliability. Results: Strong correlation was found between chronological age and TMM for males (r =.802) and females (r =.842), very strong correlation was found between age and CVM for males (r =.812) and moderate for females (r =.449), it was strong between age and SOS fusion for males (r =.810) and females (r =.643). Correlation between TMM and SOS was found to be strong for males (r =.759) and moderate for females (r =.534), it was strong between TMM and CVM for males (r =.723) and weak for females (r =.371). Very strong correlation was found between CVM and SOS fusion for males (r =.851) and strong correlation for females (r =.618). Conclusion: Good correlation was found between the degrees of TMM, fusion of SOS and CVM in young Turkish population.
