THE RELIABILITY OF BETA ANGLE IN ASSESSING CLASS III SKELETAL BASE

Dr. Sreehari S, Dr. M. Jayarama, Dr. Latheef V P

Abstract


This study aims to assess the efficiency of Beta angle, a cephlometric angle used for measuring sagittal skeletal base relationship to differentiate class III skeletal base from class I skeletal base. 30 pre-treatment cephalograms were grouped in to Class I group and Class III group each based on angle ANB, from 123 lateral cephalograms. The Beta angle values obtained were analyzed. The angle Beta is 80% sensitive and 87% specific in differentiating a Class III from a Class I


Keywords
