Correlation of Subjective Rating and Cephalometric Soft Tissue Analysis in Evaluation of Facial Profile : Factor analysis of subjective ratings with fuzzy scores

Abstract

The purpose of this study was to investigate the correlation of subjective ratings and fuzzy ratings based on cephalometric soft tissue analysis. Materials were lateral cephalogram traces of 20 females. Rators were 21 OMF surgeons and 20 orthodontists. The result of multiple regression analysis showed the form of nasolabial and labiomental region more influenced the subjective evaluation than soft tissue facial convexity.
