Abstract

Objective: To use an indigenously designed photographic soft tissue profile analysis to derive soft tissue norms for the age groups of 9-11 and 12-15 years for the local population ; to establish the normal anteroposterior relationship of mandible to the cranial base and the face ; and to examine the reliability of the four reference planes namely the SnV , GV , NV, PV.
Materials and methodology: Standardised right lateral photographs of the subjects were taken in NHP. All these images were transferred to the computer and were resized to real size images. Four lines i.e. Nasion Vertical (NV), Pupil Vertical (PV), Subnasale Vertical ( SV), and Glabella Vertical (GV) were used as reference lines and perpendicular distances of various points were measured from each of the four reference lines.
Mean and SD was calculated.
Results: Soft tissue photographic norms were generated for children with age group of 9 - 1 1 a n d 12- 15 years for class I. Important findings were B’ lies on NV for both sexes and Pog’ lies on GV for both sexes in the age group of 9-11 years which can be practically implied in routine practice. In the age group of 12- 15 years , Pog’ lies on NV in girls and is 2 mm behind it , in boys. The Nasion vertical was found to be a reliable reference plane in both the age groups.
Conclusion: The photographic analysis that was devised in this study was found to be a reliable and useful tool in recognising antero-posterior skeletal deviations related to the mandible in the two age groups studied.
