ABSTRACT:The aim of this study was to correlate Curve of Spee (COS) with various dental and skeletal cephalometric parameters. The study comprised of 110 lateral cephalograms and orthodontic study models. The subjects were divided into 5 groups on the basis of ANB angle and Angle’s molar relation. A statistically significant correlation was found between Angle’s molar relation and COS. A statistically significant linear positive relationship of COS with Jarabak Ratio and L7 to MP distance was seen. The direction of the relationship was negative in relation to L1 to MP angle. It was concluded that depth of COS was greater in Group IIb > Group IIa >GroupIIc >Group I >Group III. COS increases with an increase in Jarabak’s ratio and L7 to MP distance and decreases with increase with L1 to MP angle.
