Assessment of bone age by dental developmental seen in Orthodontia patients
Keywords:
Bone age, bone maturation, dental age, dental calcification stagesAbstract
Present trend in Orthodontics is to reduce the number of strictly needed diagnosticradiations 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.
