Abstract The ANB and "Wits" values of fifty patients were correlated to see how accurately one can predict the "Wits" value, given the ANB measurement. There is no correlation between these two values when the "Wits" measurement is negative. In our study, when the positive ANB measurement was less than 4 degrees, the "Wits" values could be either positive or negative. When the ANB angle was between 4 and 8 degrees, all "Wits" values were positive. When both the "Wits values were positive and the ANB values ranged between 1 and 8 degrees, we could predict the "Wits" measurement with a 38 percent accuracy. If the ANB range was narrowed to 4 to 8 degrees, all "Wits" values were positive and we could predict them 28 percent of the time. Both these figures are statistically significant but clinically irrelevant. Further studies are needed to determine the exact nature of these interrelationships.
