Indicators of skeletal and dental maturation in orthodontics patients presenting menarche
Keywords:
bone age, skeletal maturation stages, dental maturation stage, menarche.Abstract
The aim of present paper was to determine according menarche the bone age,skeletal maturation stages, maturation stage of cervical vertebrae and the stages of
calcification of canine and the second left mandibular premolars. A descriptive and
cross-sectional study was conducted in 30 female patients with menarche admitted
in the Orthodontics Clinic of the Stomatology Faculty of La Habana from April, 2004
to September, 2006. Each patient undergoes a lateral teleradiography of skull,
radiography of the left hand and a panoramic of periapical radiography of the left
mandibular hemiarcade. In each case the Taner-Whitehouse 2 (TW2), Grave and
Brown, Hassel and Farman and Demirjian methods were assessed. Following
variables were studied: age at menarche appearance, bone age, chronologic age,
skeletal maturation stages, the maturation stages of cervical vertebrae, calcification
stages of the canine and the second left mandibular premolar. The age mean of the
menarche's appearance in our sample was of 12.00 years with a SD of 1.00 year.
Means of bone age were higher than those of chronologic age in all age groups. The
30 study patients were in skeletal maturation stages higher then 4, in maturation
stages of cervical vertebrae higher than 1, in H stage of calcification of left
mandibular canine and in stages higher than E for the second left mandibular
premolar. In all determined methods most of patients with menarche were in more
advances maturation stages.
