Abstract
Introduction: Photography has been given a great importance in diagnosis in orthodontics, the study of certain aesthic parameter on digitilzed photographs can provide an additional diagnostic tool. This study is designed to compare facial parameters and various photographic parameters among patients with long, average, short faces in central Indian population. Also an alternative method to cephalometric analysis needs to be worked upon which is reliable, easily assessable and convenient for multiple usage by the orthodontist to direct his/her treatment. Materials and Methods: 150 subjects (75 males and 75 females) selected and examined by two methods clinical examination and photographic examination by using ImageJ software. Results: The results of this study shows there is significant correlation between vertical dimension, incisal display upper lip length, lower lip length and nasolabial angle and there is no significant difference between clinical examination and photographic examination done with Image J software. Conclusion: This study concluded that the vertical proportions of facial soft tissue follow the underlying vertical skeletal pattern, high vertical dimension is associated with short upper lip, more incisal display and high clinical FMA. The low vertical dimension is associated with acute nasolabial angle and low clinical FMA. Photogrammetry was found to be a quick easy, cost effective and reliable diagnostic tool which can reduce radiation exposure and reduce the number of cephalograms during treatment

This study is designed to compare facial parameters and various photographic parameters among patients with long, average, short faces in central Indian population. An alternative method to cephalometric analysis needs to be worked upon which is reliable, assessable and convenient for multiple usage by the orthodontist to direct his/her treatment. Record taking in orthodontics is considered immensely important as it aids in determining the finest possible treatment plan for each case.[1] This study is designed to compare facial and dental dimensions and various photographic parameters among patients with long, average, short faces in central Indian population. With the rise in demands of radiation safety there is a need to minimize radiation exposure and this technique of photographic diagnostic analysis is useful.[2] An alternative method to cephalometric analysis needs to be worked upon which is reliable, assessable and convenient for multiple usage by the orthodontist & digital photographic analysis could be one of the answer. Photogrammetry has been introduced as an alternative to direct measurements to obtain distances between facial landmarks using both two-dimensional and Orthodontic Journal of Nepal, Vol 11 No 2 July - December 2021
