Impact of upper central incisor contact with incisive canal on root resorption and retraction efficiency: A retrospective CBCT study

Key Points

• Root resorption increases with upper central incisor contact with incisive canal, affecting treatment outcomes.
• A significant correlation exists, indicated by a p-value of less than 0.05 in the analysis of cases examined.
• Retrospective CBCT analysis of dental patients showed notable differences in root behavior based on incisor positioning.
• These findings highlight a need for dental professionals to assess incisor contact to mitigate potential resorption risks.
