Concordance among skeletal maturation stages and dental calcification stages
Keywords:
Potential growth, skeletal maturation stages, dental calcification stagesAbstract
A cross-sectional research was conducted related to a technological innovation toverify that in Orthodontics patients it is possible to obviate the left hand X-ray in
assessment of the potential growth in 150 patients aged 8 and 16 seen in the
Orthodontics Clinic of Stomatology Faculty of La Habana City between 2004 and
2006. In each patient we made an X-ray of left hand determining the skeletal
maturation stages by Grave and Brown method and a panoramic or periapical X-ray
of the left mandibular hemiarcade where it was possible to determine the
calcification stages of left mandibular canine and second premolars by Demirjian et
al method. Concordance among assessed methods was estimated noting high
concordance coefficients greater in male sex and in canine (Kappa= 0,913). We
conclude that in assessment of potential growth of Orthodontics patients the left
hand X-ray may be replaced by periapical X-rays of left mandibular canine and
second premolars, allowing the carrying out of X-rays in the Stomatology service
with its benefits related to a better patient's care and saving of resources.
