The aim of this study was to introduce a simplified analysis for diagnosing mandibular asymmetry using digital OPG and to find out average gonial angle in horizontal and vertical growers. Methodology: Improvement in the beauty and harmony of facial appearance has been the main intention of orthodontic treatment since the beginning of orthodontic practice. Asymmetry in the lower third of the face is referred to as “mandibular asymmetry”, this causes Aesthetic and functional problems. Condylar asymmetry is the disproportion of vertical condyle between left and right mandibular condyles. Condylar asymmetries are thought to be one of the most important causes of mandibulofacial asymmetries. Mandibular asymmetry has been diagnosed by a combination of tools. These include clinical examination followed by extraoral photographs of frontal and side views. Radiographic aids included two‑dimensional (2D) radiographs such as lateral and posteroanterior cephalograms and also oblique radiographs of the mandible taken at 45 degrees and panoramic radiographs. 100 Digital OPG samples were collected (50 Horizontal and 50 Vertical ) , analysis for accessing mandibular asymmetry was carried out, digital OPG for diagnosing mandibular asymmetry had favourable cost benefit, low radiation exposure, significantly simplified analysis, reduces diagnosing duration, and quick tool for diagnosing. The analysis described gives a gross assessment for diagnosing mandibular asymmetries. Particularly helpful in diagnosing condylar hyperplasia, hemimandibular hypertrophy, hemimandibular elongation, coronoid hyperplasias, etc.
