title: [Rates of root resorption in orthodontically moved, periodontally affected and healthy teeth].
abstract: The aim of this SEM-study was to obtain a quantitative analysis for comparing the extent of root resorption in orthodontically treated teeth, in teeth with reduced periodontium and in healthy teeth. By using a statistically valid method the highest amount of root resorption was established in orthodontically moved teeth. The teeth with loss of attachment showed a significantly higher amount of root resorption than healthy teeth. This finding complicates orthodontic treatment in teeth with reduced periodontal attachment.
