Abstract: (900 Views)
Purpose: In this investigation, we tried to evaluate mandibular. and facial growth and study their relationship.
Materials and Methods: Using cluster sampling, 2200 subjects (1100 boys and 1100 girls) of different age-groups (0, 1, 3, 5, 7, 10, 12, 14, 16, 18 and 20 years) from vairous social groups were studies. Twins, cases with musculoskeletal disturbances, etc. Were excluded. We used comopses, rouler and Morrisons calipers for our measurements. The studied parameters were mandibular lenght, mandibular height, facial length. These parameters were measured according to anatomical and anthropometric guidelines. The data for this study was analyzed with the, SPSS software package. Statistical tests like ANOVA, t test, and Pearson correlation coefficient were also used.
Results: Detailed results of this study are presented in the Tables and Figures. The results showed that all mandibular and facial dimensions undergo. growth and development since the beginnign of life. Tooth eruption, number and size of teeth, and epiphysial and membranous growth of the mandible in different ages and during pubertal period cause variations in the growth rate of the mandible and face. The greatest amount of mandiblular and facial growth occur in the first 3 years of life, especially in the first year. Also there is a growth spurt, especialy for the mandibular lenght, height and facial lenght.
Conclusion: At last, investigations discerned that during the first 20 years of life, mandibular lenght grows to about 2 times its birth value; Mandibular height grows to more than 2 times; facial length grows to about 2 times its birth value. The most vigorous correlation was observed among facial parameters and mandibular lenght and height.
