TOLEDO MAYARI, Gladia  and  OTANO LUGO, Rigoberto. Assessment of bone age by dental developmental seen in Orthodontia patients. Rev Cubana Estomatol [online]. 2009, vol.46, n.3, pp. 1-8. ISSN 1561-297X.

Present trend in Orthodontics is to reduce the number of strictly needed diagnostic radiations that is why bone maturation indexes have been created by dental developmental including the Demirjian et al method, substituting the hand radiography which is an additional strategy for patients due to it is not performed in Stomatology Services. To determine the bone age by dental developmental, a cross-sectional and transversal study was carried out and also a left hand radiography and a panoramic and a periapical one of left mandibular hemicardia in 150 orthodontic patients determining the bone age by Tanner-Whitehouse 2 method (TW2) and Demirjian et al. There were very significant high correlations among estimated bone ages in both sexes (females r = 0.828 and males r = 0.957). We conclude that estimated bone age by dental developmental in our universe may be applied to predict bone age through TW2 method with a possible substitution of left hand radiography.
