Abstract
Aim:To investigate the changes in soft tissue parameters of three age groups of untreated Yemenis females.Materials and Methods:The sample comprised 300 Yemeni females which were randomly selected and divided according to age into three equal groups (Group I: 7.34 ± 0.65 years [prepubertal], Group II: 11.11 ± 1.07 years [pubertal], and Group III: 22.17 ± 3.04 years [postpubertal]). Lateral cephalometric radiographs were taken for each subject, and soft tissue measurements were performed. Comparison between the three groups was done. One cephalogram representing the mean of its group was selected from the three groups; the selected three cephalograms (one from each group) were superimposed for growth changes evaluation.Results:Linear, as well as angular soft tissue measurements were significant for all measurements between the different age groups except Ls-Sn Pog’, Li-Sn Pog’, GSn Pog’ and nasolabial angle, respectively.Conclusion:The identified changes with growth in Yemeni females having Class I skeletal and dental relationship should be considered during planning for orthodontic and/or orthognathic treatments.
