Comparison of Cephalometric Norms of Pleasing Faces Reporting to OPD of Orthodontic Department L.U.M.H.S Jamshoro / Hyderabad

Abstract

Objective: This study was aimed to analyze cephalometric norms in Pakistani population in comparison with  the standards  of  European-American Adults.

Study Design: Cross sectional study

Place and Duration of Study:  This study was carried out at Dental  OPD Department of Orthodontic Dentistry Liaquat University Hospital Hyderabad/Jamshoro from August 2012 to December 2012.

Materials and Methods: Cephalometric   norms   were analyzed on a sample of 60 patients, with full complement of permanent teeth and no previous orthodontic treatment. The consent was taken and the patients were informed for the amount of radiation exposure related to cephalometric radiography. Lateral cephalometric radiographs of the patients were exposed in centric occlusion. The cephalometric radiographs of patients were traced manually on acetate papers. Each radiograph of the patient was traced at the same sitting to minimize tracing errors. In this study nasolabial angles were measured for comparison with European-American Adults. The database of study sample measurements was developed in SPSS version 17 . The arithmetic mean, range and standard deviation for all the concerned variables were determined using the above-mentioned software with the help of SPSS processor. P value < 0.05 was considered significant.

Results: The results suggest that the study  sample  comprised of  (53.3%) males and 28 (46.7%) females. Nasolabial angle of the patients were statistically analyzed and the minimum angle noted  was 90 degree, maximum was 150 degree, mean angle was 108.45 degree and standard deviation was 10.98 degrees  (p < 0.001).Females showed more sharp nasolabial angles  (p < 0.01).

Conclusion: Comparisons revealed statistically significant differences in cephalometric norms between the study population  in comparison to standers of  European-American population .
