A conservative approach to treat large periapical lesions: A report of two cases

Abstract

Pulpal tissue necrosis transforms the pulpal chamber into an unprotected environment. This environment becomes susceptible to colonization by numerous microorganisms that inhabit the oral cavity. Periapical lesions are formed as a result of the immunologic host response to bacteria or its products. These periapical lesions cannot be differentially diagnosed as either radicular cysts or apical granulomas based on radiographic evidence alone. The exact mechanism by which periapical cysts heal is also not clearly understood. In these case reports, root canal treatment proved successful in promoting the healing of large periapical lesions. This confirms that periapical lesions can respond favorably to nonsurgical treatment.
