Effects of intracanal medicaments on inflammatory resorption or occurrence of ankylosis in mature traumatized teeth: a review

A review of the literature of the effect of intracanal medicaments on inflammatory resorption or occurrence of ankylosis in mature traumatized teeth is presented. The results of the studies show that calcium hydroxide and Ledermix paste eliminate inflammatory resorption. Other medicaments such as gutta‐percha with sealer, antibiotics, and calcitonin reduce or almost eliminate this complication. Ankylosis or replacement resorption develops in the root surfaces of teeth with mature roots irrespective of medicaments used. However, the percentage of relative surface area of the root which develops ankylosis is significantly higher in mature teeth treated with calcium hydroxide than in teeth treated with permanent root filling. Ledermix paste targets the resorbing cells without damaging neighbouring tissue. Recommendations for the use of calcium hydroxide and Ledermix paste as intracanal dressings in traumatized mature teeth are made.
