Perforation of the root canal during insertion of an intracanal post is a complication of endodontic therapy. Mineral trixoide aggregate (MTA) has been successfully used a sealer in these situations. This material has recently been formulated in white color, allowing its application in areas of esthetic concern. This is a clinical case report of a root perforation sealed with gray MTA that resulted in discoloration of the marginal gingiva. Treatment consisted of replacing gray MTA with white MTA with the aid of a dental operating microscope, producing satisfactory esthetic results.
