The significance of diagnosis and treatment planning in periapical lesion overfilled with calcium hydroxide paste

Abstract

Calcium hydroxide has been widely used for root canal dressing material in endodontic treatment. This report describes that when the accurate diagnosis and proper nonsurgical endodontic retreatment is applied to periapical lesion with accidentally extruded calcium hydroxide paste, the lesion can be successfully treated. Overfilled calcium hydroxide can affect the healing process, so the overextension of calcium hydroxide agent should be avoided. (J Dent Rehabil Appl Sci 2021;37(2):95-100)
