Haavikko'S Method To Assess Dental Age In Italian Children
EUROPEAN JOURNAL OF ORTHODONTICS(2009)
摘要
The aim of this study was to determine if Haavikko's maturation standards are applicable to Italian children. The sample included 500 healthy Caucasian children 3.9-15.4 years of age: 267 girls [mean age 9.6 years, standard deviation (SD) 2.1] and 233 boys (mean age 9.9 years, SD 2.1), living in Italy. All dental ages were assessed from panoramic films by one examiner using Haavikko's method. A second examiner independently scored 48 panoramic films to evaluate the reproducibility of the dental age measurements.A good correlation (0.95) was found, as shown by Cohen's kappa. To evaluate the relationship between dental age estimated by Haavikko's standards and the chronological age of the Italian sample, Bland and Altman's graphical method was employed. Moreover, centiles of dental age were constructed both for girls and boys using the LMS (L = skewness, M = median, S = coefficient of variation) method of Cole and Green.It was found that Haavikko's standards tended to underestimate chronological age in this Italian sample. Dental maturation standards as described by Haavikko do not appear suitable for Italian children; instead, centile curves constructed for girls and boys using the LMS method could be used for the estimation of dental age in the Italian population.
