The effect of periradicular endodontic pathosis on the apical region of adjacent implants.

Implants have become standard for dentate individuals. A potential problem to consider is implant lesions from microbial contamination; these may occur if there is not careful diagnosis and treatment planning. A factor of concern during treatment planning is the pulpal and periradicular condition of teeth adjacent to the implant site. Periradicular pathosis may jeopardize the implant. Therefore, if endodontic pathosis is identified, root canal treatment or extraction should be initiated before implant placement to prevent microbial contamination of the implant during healing. In reviewing clinical cases, the authors found several that illustrated problems with adjacent teeth that contributed to inflammation surrounding the implant.
