The Wits appraisal among a Nigerian sub-population: an assessment of dental base geometric factors

The Wits appraisal is a common linear cephalometric analytic tool established by Jacobson. It has been reported to be superior to angular cephalometric measures as it is not dependent on pericranial structures and their variations both during growth and orthodontic treatment. AIM: To obtain reference values for the Wits appraisal among Nigerians and assess the effect of the dental base geometry on it. METHODS: Lateral cephalometric radiographs of 100 Nigerian subjects with normal occlusion were analyzed to obtain the Wits appraisal, and the effect of the vertical distance from subspinale to su...
