CRANIOFACIAL CHARACTERISTICS IN KINH ETHNIC CHILDREN FROM 7 TO 9 YEARS OF AGE ON LATERAL CEPHALOGRAMS USING RICKETTS ANALYSIS
Main Article Content
Abstract
Objectives: To determine craniofacial characteristics and evaluate the growth of Kinh ethnic children from 7 to 9 years old on lateral cephalograms. Subjects and methods: A longitudinal study of 206 children (104 males, 102 females) from 7 to 9 years old in Lien Ninh primary school, Thanhtri, Hanoi by measuring on lateral cephalograms according to Ricketts analysis. Results: Average of total facial height (Ba-N/Xi-Pm), lower facial height (Ans-Xi-Pm) and mandibular plan angle (Go-Me/Fh) were no difference between male and female in 7 years old children, but in class III was larger in class I and II Angle. Conclusion: Most of craniofacial dimensions were no difference between male and female, craniofacial growth in female was significantly sooner than in male.
