TOLEDO MAYARI, Gladia  e  OTANO LUGO, Rigoberto. Assessment of bone maturation in cervical vertebrae in Orthodontics patients. Rev Cubana Estomatol [online]. 2010, vol.47, n.3, pp.326-335. ISSN 0034-7507.

Objective: To verify if it is possible to avoid the left hand radiography in assessment of bone maturation in Orthodontics patients. Methods: A cross sectional and descriptive study was conducted in 150 patients admitted in the Orthodontics Clinic of Stomatology Faculty of Havana City from April, 2004 to September, 2006. Patients selected had a good general health status, lack of chronic diseases and of oligodontias, as well as those with malocclusion and that will need a lateral teleradiography of skull carrying out in each patient and also a left hand radiography. In each case Grave's and Brown's and Hassel's and Farman's methods identifying the concordance among them by Kappa coefficient. Results: There were high and very significant statistic concordance coefficients among the assessment carried out in left hand and by cervical vertebrae: female sex Kappa= 0,828 (p< 0,010) and male sex Kappa= 0,767 (p< 0.010). Conclusion: In study patients the bone maturation may be assessed by cervical vertebrae being possible to replace the left hand radiography allowing a resources saving and a better care to patient.
