I performed an extraction of tooth #30. The tooth was endodontically treated and badly broken down but without a periapical lesion. During the extraction I sectioned the tooth and took off the distal root. The mesial root was broken and I took it out in multiple pieces. After I finished the extraction I took a PA radiograph and I did not notice the presence of a remaining root tip. I grafted the site and and dismissed the patient and prescribed antibiotics for 10 days. At the next week follow up visit, healing was within normal limits, but when I reviewed the PA radiograph I noticed the root tip. I informed the patient about what happened and I feel so badly about it. I did not want to interrupt the healing at that time so I did not try to remove it. My question do I have to remove the tip and if so when is the best time? Â What is the best technique for removing the root tip? Will it be possible to just drill it out when I prepare the osteotomy site? Â What do you recommend?
