Cervical XXXX in subjects with Class II malocclusion assessed by lateral cephalogram and cone beam computed tomography.

@entity1 @entity5788 @entity154 @entity3232
A high prevalence of @entity5788 ( @entity5788 ) has been recently associated with @entity3232 . Our aim was to study the prevalence of @entity5788 on lateral cephalograms in Class II subjects and to compare the findings with those obtained from cone beam computed tomography (CBCT). Standardized cephalograms of 238 Class II @entity1 were analysed for @entity5788 . Cephalogram and CBCT were available for an additional 21 subjects. Cephalometric values were correlated with vertebrae morphology; logistic regressions and intraobserver agreement were evaluated. Inspection of lateral cephalograms could exclude @entity5788 in 90.3 per cent of the subjects, while 9.7 per cent showed potential fusions. No correlations were found between the cephalometric values and potential @entity154 . In the 21 @entity1 with a CBCT and a lateral cephalogram, the visual assessment of the cephalogram yielded a potential fusion in nine cases. None could be confirmed by CBCT. A low number of potentially fused cervical vertebrae could be detected on lateral cephalograms. The possible fusions did not correlate to any cephalometric values nor could they be confirmed by CBCT, the gold standard for assessing @entity5788 . Visual examination of a cephalogram may result in a false-positive finding and does not allow reliable diagnosis of @entity5788 .
