DECIDING MOST IDEAL SAGITTAL DYSPLASIA INDICATOR– A COMPARITIVE STUDY IN NORTH– KARNATAKA POPULATION.

Dr B Nishanth, Dr Neelkantha Patil

Abstract :

AIMS AND OBJECTIVES:– In orthodontic diagnosis and treatment planning, assessment of anteroposterior discrepancy is of importance to the orthodontist. Both angular and linear measurements have been incorporated into various cephalometric analysis to help the clinician diagnose anteroposterior discrepancies and establish the most appropriate treatment plan. Hence the present study is designed to compare various sagittal discrepancy indicators in North– Karnataka population.

MATERIALS AND METHODS:– The sample was screened from the old records of the Department of Orthodontics and dentofacial orthopedics, AME’s Dental College and hospital, Raichur and from other colleges of North– Karnataka region. 90 pretreatment cephalometric radiographs (18 from each district) were subdivided based on ANB angle and Wits appraisal into skeletal Class I, II, III. Various sagittal dysplasia indicators included in the study are ANB Angle, Wits appraisal, APDI, Quadrilateral analysis, McNAMARA maxillomandibular angle, APP– BPP, BETA Angle, YEN angle, PI angle and W angle where in ANB ANGLE is taken as standard.

The results and statistical analysis were done to determine the more reliable sagittal dysplasia indicator.

CONCLUSION:– According to the study the order of significance is ANB angle, Pi analysis, Yen angle, W angle and Beta angle. So, more than one cephalometric analysis had to be used according to the need to quantify the results.
