Mesiodistal Crown Size In Relation To The Risk And Severity Of Malocclusion, Jon Robert Zang-Bodis May 2009

Mesiodistal Crown Size In Relation To The Risk And Severity Of Malocclusion, Jon Robert Zang-Bodis

Theses and Dissertations (ETD)

From among numerous potential causes of dental malocclusion, tooth size has been implicated as one factor. Prior studies show that mesiodistally larger teeth increase the risk of malocclusion. The present report extends our understanding by testing for graded responses between crown size and the extent of dental malocclusion. Maximum mesiodistal crown dimensions of all 14 permanent tooth types (excluding third molars) were measured in 207 American white adolescents (routine orthodontic patients), and 10 measures of malocclusion (e.g., rotations, displacements, spacing) were recorded. Analysis of covariance (controlling for sexual dimorphism in tooth size) disclosed (1) significant positive associations between …
