Impact of Archwire Presence and Adhesive Removal Techniques on Enamel Crack Formation During Orthodontic Bracket Debonding: An In Vitro Study. [PDF]

Clin Exp Dent Res
ABSTRACT Objectives Enamel cracks are a common complication following orthodontic bracket debonding and the removal of adhesives. This study investigated whether the presence of an archwire during debonding and the use of turbine (high‐speed) versus angle (low‐speed) tungsten carbide burs affect the number, length, or orientation of enamel cracks ...
