ABSTRACT
Introduction: Attainment of the best results post orthodontic treatment is majorly dependent on proper diagnosis and a good treatment plan. Diagnostic records lay the foundation of formulation of a good treatment plan. Among which lateral cephalograms and panoramic radiographs are important tools. Required knowledge about various parameters can be obtained by making certain linear and angular measurements. Gonial angle is one such parameter which helps an orthodontist in determining the facial pattern of an individual and thus altering the treatment plan as required.
Objective: The aim of the present study was to evaluate the efficiency of lateral cephalograms and panoramic radiographs in the determination of right and left gonial angle and determination of the accuracy of both.
Materials and Methods: Pre–treatment lateral cephalograms of 120 skeletal class I subjects were randomly selected and divided into 60 males and 60 females. Radiographic landmarks were located, identified and marked and various measurements were made. The measurements thus obtained were statistically analysed.
Results: The mean value of gonial angle measured using the panoramic radiograph was 124.75 and that of lateral cephalogram was 125.12. No statistically significant difference was found between the gonial angle measured using lateral cephalograms and that using panoramic radiographs.
Conclusion: With the present study, it can be concluded that both lateral cephalograms and panoramic radiographs effectively measure the gonial angles. However, no statistically significant difference was found in the measured angle with the two radiographs.
