Nasolabial angle assessment, in a sample having a class I molar relationship

This study was conducted to determine the similarity of nasolabial angle of our population with the standardized norms. A sample, selected on the basis of having a class I molar relationship, was radiographed and their Nasolabial angle was measured to find if a variation existed between our sample and the standard value. The mean value of nasolabial angle of our sample was 102° +/- 9°Compared to the standard value of 102° +/- 8°. Value of nasolabial angle in our sample was similar to the standard value given by McNamara in his soft tissue analysis, with no sexual dimorphism present
