ABSTRACT
Anthropometric measurements can be correlated to cephalometric values and have a complementary role to facilitate diagnosis. This Study aimed to determine the correlation between lateral cephalometric and anthropometric indices in the Iranian population. A cross-sectional study using Anthropometric-Cephalometric indices was carried out on 26 subjects with normal occlusion and harmonious facial ratios. Fiberglass meter, wooden ruler and millimetric Anthropometer [Aesculap Inc.] was used as well as hand-made instruments to measure the palm length and angles of the hand. General measurements including height and weight were also taken. For cephalometric measurements, radiographs were taken by an oral and maxillofacial radiologist. Data were subjected to SPSS 9 software. To determine the normal distribution Kolmogorov-Smirnov test was used and P<0.05 was considered significant. Also Spearman and Pearson coefficient correlation was calculated and t-test was performed. In 12 of the 26 cases the correlation coefficient regarding the bizygomatic width [FW] with lower face height [LFH], SE, S-Gn; facial height [FH] with Pog to NB, Nasion-Menton; upper lip vermilion with SE, weight with ANB, Ar-Go; LFH with Ar-Go, forearm length with angle of facial convexity, height with Na-ANS were significant at p<0.01. There was correlation between LFH and FW and Facial Depth that infers three-dimensional proportional facial growth. The forearm length and the facial convexity angle [non-craniofacial anthropometric indices] have a negative co-efficient of correlation. This means that the longer the forearm the straighter the profile. Though there are numerous statistically significant relations between anthropometric and cephalometric indices, in this study these relations were not so clinically momentous in most of the cases
