Title: Soft tissues cephalometric norms for a sample of Sudanese adults. Part II: Arnett’s analysis
Author: Abuaffan, Amal H.; Hamid, Marwa M.
Abstract: Purpose: To establish standards for Arnett’s STCA in a sample of Sudanese adults and compare them to other populations. Materials and Methods: A hundred and six lateral cephalograms of Sudanese adults (55 females and 51 males) aged 18-25 years with a mean of 22.8 years were analysed using Arnett’s STCA. Results: When compared to Caucasians Sudanese adults had statistically significant more proclined upper and lower incisors in relation to their occlusal planes, more protrusive upper and lower lips, obtuse maxillary occlusal plane angle, thicker upper and lower lips and increased TVL projection to B’ and Pog’ points. In addition, males had thicker lips, more proclined lower incisors and longer upper lips than females. Conclusion: There are remarkable differences in the soft tissue norms results between Sudanese adults and Caucasians and also between Sudanese and other populations These variations are most likely to be due to racial and genetic background differences among various populations and must be taken into consideration during diagnosis and orthodontic treatment planning.
