The null hypothesis was that obese and normal-weight patients show similar degrees of skeletal maturation. </p><p>  <strong>Methods</strong> The sample for this retrospective study consisted of 50 white patients (28 boys, 22 girls) whose x-rays (hand-wrist and lateral cephalometric radiographs) were already available. The test group included 25 obese patients (11 girls, 14 boys average age, 9.8 ± 2.11 years), and the control group included 25 subjects of normal weight (11 girls, 14 boys average age, 9.9 ± 2.5 years). Skeletal maturation was determined by using the carpal analysis method and the cervical vertebral maturation method. </p><p>  <strong>Results</strong> According to the carpal analysis, there was a significant difference between skeletal and chronologic ages between the test group (11.8 ± 11.4 months) and the control group (–2.9 ± 3.1 months). Furthermore, the obese subjects exhibited a significantly higher mean cervical vertebral maturation score (2.8 ± 0.7) than did the control subjects (2 ± 0.6) (P <0.05). </p><p>  <strong>Conclusions</strong> Compared with the normal-weight subjects, the obese subjects showed a higher mean discrepancy between skeletal and chronologic ages according to the carpal analysis and had a significantly higher cervical vertebral maturation score. Thus, to account for the growth in obese patients with skeletal discrepancies, it might be necessary to perform examinations and dentofacial and orthopedic treatments earlier than in normal-weight subjects. </p><hr><p> <strong>Source: </strong>Journal of Orthodontics and Dentofacial Orthopedics </p><p><a href="http://www.ajodo.org/article/PIIS0889540612007743/abstract" target="_blank"><font color="#0000ff">  Full Text</font></a></p> 0 0 http://idai.ir/browse.php?a_code=A-10-32-763&slc_lang=en&sid=1 Maria Rita Giuca 10031947532846003231 10031947532846003231 No Department of Surgery, University of Pisa, Pisa, Italy Marco Pasini 10031947532846003232 10031947532846003232 No Department of Surgery, University of Pisa, Pisa, Italy Simona Tecco 10031947532846003233 10031947532846003233 Yes Department of Health Science, University of L'Aquila, L'Aquila, Italy Enrico Marchetti 10031947532846003234 10031947532846003234 No Department of Health Science, University of L'Aquila, L'Aquila, Italy Laura Giannotti 10031947532846003235 10031947532846003235 No Department of Surgery, University of Pisa, Pisa, Italy Giuseppe Marzo 10031947532846003236 10031947532846003236 No Department of Health Science, University of L'Aquila, L'Aquila, Italy
