From: Endodontic remnants are found more than other radiopacities in proposed implant sites
Different forms of remnants of endodontic fillings radiopacities related to extraction sites: a small radiopacity deep in maxillary extraction sites, b radiopacities in mandibular extraction sites with or without evidence of tissue reaction, c remnants of filling radiopacities at the periphery of bone in maxilla and mandible, d radiopacities near implant sites in mandible and maxilla, e two radiopacities in the same extraction site, f more than 2 radiopacities in different sites or in the same extraction site
