COMPARISON OF CEPHALOMETRIC CRANIOFACIAL FEATURES AND FACIAL PHOTOGRAPHIC FEATURES FOR TWO GENERATIONS OF PATIENTS

Objective: To estimate the correlation and variant heritability values of craniofacial variables between parents their offspring. Materials Methods: The sample comprised 20 Indian families; each family consisted father, mother, son, daughter. Lateral cephalometric radiographs facial photographs were taken for member.Fifty -three angular, linear, proportional measured photographic analysis was done. Interfamilial correlations (h2) estimated among father-son, father-daughter,mother-son, mother-daughter pairings. Results: most similar angular measurements offspring as follows:SNA0,SNB0 ,ANB0 ,FMA0, MP-FH0 , LI-NB0, Op-FH0 ,UI-NA0 OP-SN0, LI-NB0 linear follows: Co-Pt.A,Co-Gn, N- ANS, UI-A, Me-Me’,LI-A.Pog, Mx 1 exposure. Both coefficients heritable stronger in father-offspring than mother-offspring Conclusions: overall h2 mean three types showed groups, with father –son pairings more significant father-daughter groups. KEY WORDS: Cephalometrics; Heritability; Facial photographs; Craniofacial features; Offspring.
