Craniofacial shape from pre- to post-adolescence.

Popis výsledku v původním jazyce

Aim: Craniofacial growth demonstrates significant variation and is difficult to predict. The aimof the present investigation was twofold: (1) to assess the association (covariation) betweencraniofacial shape at pre- and post-adolescence and (2) to evaluate if pre-adolescent craniofacialshape is related (covaries) with growth magnitude and direction.Subjects and methods: One hundred fifty subjects (86 males and 64 females) untreatedorthodontically were selected from AAOF Craniofacial Growth Legacy Collection. Each subject hadcephalograms taken before 9 (pre-adolescent stage) and after 15 years of age (post-adolescent).Fourteen curves comprising 123 points (10 fixed and 113 sliding semilandmarks) comprehensivelycovering the craniofacial skeleton were digitally traced on each cephalogram. Procrustes alignment,principal component analysis, 2-block partial least squares (2B-PLS) analysis, and regressionanalysis were done after sliding the semilandmarks to minimize bending energy.Results: The first 16 principal components (PCs) were non-trivial and explained 85.2% of totalshape variability in the sample. PC1 depicted mainly variability in the vertical direction, PC2represented mostly variability in the saddle angle and in the antero-posterior position of themandible, and PC3 depicted primarily variability of the mandibular shape (steep versus flatmandibular plane). The covariation between pre- and post-adolescent facial shape was statisticallysignificant, both in the pooled sample (RV coefficient = 0.604) and in boys (RV = 0.639) andgirls (RV = 0.629). The pre-adolescent shape was weakly associated with the magnitude of facialchange—2-block PLS analysis demonstrated that blocks 1 and 2 were independent (P = 0.118,RV = 0.035).Conclusions: The pre-adolescent shape of the craniofacial complex explained approximately 60%of the post-adolescent shape of the craniofacial complex; however, the relationship between preadolescent shape of the craniofacial complex and magnitude of its change was weak.
