Photographic Study of Lip Anthropometric Pattern Development in the Fars Family in Mashhad

introduction: anthropometry (morphometry of the human) is measurement of linear and angulardimensions of the human body. since the anthropometric parameters which are based on age,sex, geographical location and ethnic characteristics of the human species are different, therefore,anthropometric studies of population by age and sex should be done separately. methods: in this study, anthropometric measurements lips and different patterns of lip line werestudied in 133 males (4-40 years) with persian ethnic who were living in mashhad. these personshad no inflammation, herpes, malformations such as cleft lip, and surgery history in lib and jaw.lip full-face photos were taken using a digital camera (nikon, 12.3 mega pixels). anthropometricmeasurements of mouth width (ch-ch); width of philtrum (cph-cph); height of the total lip ((ls-li;)the entire lip area (total area) were measured on computer by mip software. data were evaluatedstatistically using spss, polynomial regression and anova models (p<0.001). results: there was a significant correlation between age and parameters of the mouth width, lipsheight to nose and total area of the lip. conclussion: considering significant relationship between the quantities investigated and age, wecan use anthropometric data of lips in many fields including medical, criminal, etc. by comparingthis study with other studies, it can be concluded that there is the most similarity in the size oflip of persian men in mashhad with men living in india. it is hoped that in the similar futurestudies, extensive statistical societies be prepared in each races of turks, baluchis, kurds in orderto complete anthropometric database of lip in iranian persian ethnics.
