Brief Summary

The present day social setup considers facial charisma as an important physical characteristic. The facial characteristics of an individual are measured through anthropometry, photogrammetry, computer imaging and cephalometric radiographs. Cephalometric radiographs offer significant diagnostic information regarding the association between the dental and skeletal structures. By means of photogrammetric measurements, a fresh diagnostic resource is accessible to the orthodontist which permits an intangible, radiation free attainment of measure points of soft tissue with no instrumental expense and radiation to the patient. Orthodontic patients range from adolescents to senior citizens and originate from an assortment of populations, thus an extensive series of representative norms will be ideal. Knowledge of the normal dentofacial outline of every group will make certain better success of treatment to set up the best possible facial agreement. Hence, it is extremely important to assess the soft tissue profile of a patient as it is one of the most vital components of orthodontic diagnosis and treatment planning. The purpose of the present study is to evaluate the photographic characteristics of soft tissue facial profile of patients with class II malocclusion as ethnic differences have been found to be reported in the literature. It is hypothesized that soft tissue facial characteristics on lateral profile photographs and lateral cephalometric radiographs in a sample of local population with class II malocclusion are closely related.

Conditions

Class II Malocclusion

Keywords

Photographic analysis; Cephalometric analysis; Standardized photographs; Angular measurements; Linear measurements; Malocclusion; Facial Profile

Outcome Measures

Primary Outcomes (1)

• Mean values of facial profile angles and linear measurements

  Mean values of soft tissue angles and linear measurements will be determined both on cephalographs and photographs separately.

  Within one week after cephalographs and photographs have been taken.

Secondary Outcomes (1)

• Comparative angular and linear parameters

  Within two weeks after cephalographs and photographs have been taken.
