Abstract

This study was conducted to evaluate and correlate nasolabial angle, mentolabial sulcus angle and throat angle using cephalometric and photographic measurement. Material and methods: A sample size of 30 subjects were included in the study. Lateral cephalograms were taken of all the subjects using CS 8000C (Carestream Health, Inc, France) in the department of Oral Medicine and Radiology, Inderprastha Dental College and Hospital. The lateral cephalograms were manually traced by one investigator. 3 parameters were evaluated in each lateral cephalogram. Similarly lateral profile photograph for each subject in NHP (natural head position) was also taken from canon 1500d DSLR camera. 3 parameters were also evaluated in each lateral profile photographs. All the data were collected and statistically analyzed using SPSS statistical software. Comparison was assessed by using Student t-test. Correlation was assessed by Pearson correlation test. Results:The average value for nasolabial angle, mentolabial angle and throat angle were found to be 92.46°± 9.43o, 103.66°± 20.27° and 129.6°± 13.86° respectively when assessed from cephalometric radiograph. The average value for nasolabial angle, mentolabial angle and throat angle were found to be 93.4°± 10.61°, 108.1°± 2.97° and 129.1°± 16.03° respectively when assessed from profile photograph. Conclusion: The current study came to the conclusion that photography, which enables the recording of significant numbers of photographs for analysis, is a reliable and cost-effective tool for identifying soft tissue landmarks
