However, current trend shows a paradigm shift from the conventional hard tissue analysis to also include both hard- and soft-tissue analysis. The objective of our study was to determine the soft-tissue cephalometric norms for the Lambada population, to define gender differences and to correlate the variables, skeletal convexity (SC), and H angle (HA).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods:<\/jats:title>\n                    <jats:p>Fifty subjects of Lambada ethnic group between 18 and 26 years old, grouped into 25 males and 25 females were taken. Their lateral cephalograms were obtained and analyzed using Holdaway's analysis.

The variable, lip strain showed that the upper denture is protrusive (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt;0.001). Skeletal convexity and HA were significantly correlated in the female sample. HA revealed that a slightly more protrusive profile was acceptable for this ethnic group.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Although established Caucasian norms are applicable to the Lambada ethnic tribe, few parameters like basic upper lip thickness (ULT) and upper lip strain (ULS), skeletal convexity, inferior sulcus to H line (LS-H) were significantly different. The male group exhibited straighter profile, thicker lips, prominent nose, deep mentolabial sulcus, and a prominent chin than females. The differences could be considered in diagnosis and treatment planning for orthodontic practice and for orthognathic surgery.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/0970-9290.102224","type":"journal-article","created":{"date-parts":[[2012,10,10]],"date-time":"2012-10-10T19:42:42Z","timestamp":1349898162000},"page":"353-358","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":6,"title":["Soft-tissue cephalometric norms for the Lambada population in Telangana Region of Andhra Pradesh"],"prefix":"10.4103","volume":"23","author":[{"given":"Mayuri","family":"Thomas","sequence":"first","affiliation":[{"name":"Department of Orthodontics and Dentofacial Orthopedics, Sri Sai College of Dental Surgery, Vikarabad, Andhra Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Val Deepti","family":"Reddy","sequence":"additional","affiliation":[{"name":"Department of Orthodontics and Dentofacial Orthopedics, Sri Sai College of Dental Surgery, Vikarabad, Andhra Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hanumantu Vidyadar","family":"Lakshmi","sequence":"additional","affiliation":[{"name":"Department of Orthodontics and Dentofacial Orthopedics, Sri Sai College of Dental Surgery, Vikarabad, Andhra Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R2-20260302","doi-asserted-by":"crossref","first-page":"279","DOI":"10.1016\/0002-9416(84)90185-4","article-title":"A soft-tissue cephalometric analysis and its use in orthodontic treatment planning- Part II","volume":"85","author":"Holdaway","year":"1984","journal-title":"Am J Orthod"},{"key":"R3-20260302","first-page":"72","article-title":"Ethnic Differences in the soft tissue profile of Korean and European-American adults with normal occlusions and well-Balanced balanced faces","volume":"72","author":"Hwang","year":"2002","journal-title":"Angle Orthod."},{"key":"R4-20260302","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1016\/0002-9416(83)90144-6","article-title":"A soft-tissue cephalometric analysis and its use in orthodontic treatment planning - Part I","volume":"84","author":"Holdaway","year":"1983","journal-title":"Am J Orthod"},{"key":"R6-20260302","doi-asserted-by":"crossref","first-page":"927","DOI":"10.1016\/S0096-6347(39)90386-8","article-title":"Some facial features and their orthodontic implications","volume":"25","author":"Hellman","year":"1939","journal-title":"Am J Orthod Oral Surg."},{"key":"R7-20260302","first-page":"121","article-title":"The Frankfort mandibular incisor angle (FMIA) in orthodontic diagnosis, treatment planning and prognosis.
