Abstract:BackgroundIn conjunction with post placement in root‐filled teeth with periapical healthy conditions, root canal retreatment may be performed to improve the seal of the root canal. Whether root canal retreatment for technical reasons (retreatments in teeth without apical periodontitis (AP)) results in lower frequency of AP is unknown.ObjectiveTo examine whether there is a difference in frequency of AP between roots with root canals retreated for technical reasons, and roots with root canals not retreated befor… Show more
