“…Our study shows that Wits values were non-significant (P-0.723) amongthree groups. This is also supported by Moore et al 15 and Ishikawa et al 16 who also stated that Wits appraisal although not affected by landmarks or jaw rotations; it still has the problem of correctly identifying the functional occlusal plane, which can sometimes be impossible, especially in mixed dentition. Furthermore, changes of the Wits measurement throughout orthodontic treatment might also reflect changes in the functional occlusal plane rather than pure sagittal changes of the jaws.…”

“…[18] 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 results showed no correlation between these two values when the “Wits” measurement is negative.…”

Background:Commonly used parameters for anteroposterior assessment of the jaw relationship includes several analyses such as ANB, NA-Pog, AB-NPog, Wits appraisal, Harvold's unit length difference, Beta angle. Considering the fact that there are several parameters (with different range and values) which account for sagittal relation, and still the published literature for comparisons and correlation of these measurements is scarce. Therefore, the objective of this study was to correlate these values in subjects of Indian origin.Materials and Methods:The sample consisted of fifty adult individuals (age group 18-26 years) with equal number of males and females. The selection criteria included subjects with no previous history of orthodontic and/or orthognathic surgical treatment; orthognathic facial profile; Angle's Class I molar relation; clinical Frankfort Mandibular plane angle FMA of 30±5° and no gross facial asymmetry. The cephalograms were taken in natural head position (NHP). Seven sagittal skeletal parameters were measured in the cephalograms and subjected to statistical evaluation with Wits reading on the true horizontal as reference. A correlation coefficient analysis was done to assess the significance of association between these variables.Results:ANB angle showed statistically significant correlation for the total sample, though the values were insignificant for the individual groups and therefore may not be very accurate. Wits appraisal was seen to have a significant correlation only in the female sample group.Conclusions:If cephalograms cannot be recorded in a NHP, then the best indicator for recording A-P skeletal dimension would be angle AB-NPog, followed by Harvold's unit length difference. However, considering biologic variability, more than one reading should necessarily be used to verify the same.

“…The Wits analysis was used as the gold standard in this study. Various studies have shown a moderate correlation between the ANB angle and the Wits value [2,3,9,14]. This leaves the question open as to which of the two procedures best reflects the actual sagittal base relationship.…”

“…In der vorliegenden Studie wurde die Wits-Analyse als Goldstandard angewandt. Verschiedene Studien zeigten eine mäßige Korrelation zwischen dem ANB-Winkel und dem Wits-Wert [2,3,9,14]. Hierbei bleibt die Frage offen, welches der beiden Verfahren die tatsächliche sagittale Basenrelation widerspiegelt.…”
