RECALL
Recall evaluations to assess long-term healing are important. Some failures after surgery are evidenced only by radiographic findings. A I-year follow-up is generally a good indicator. If, after 1 year, radiographic evidence shows no decrease in lesion size or lesion size increases, it generally indicates a failure and persistent inflammation. P’ A decrease in lesion size (indicating hard tissue formation) may lead to complete healing and requires evaluation at 6 to 12 months, Of course, persistent. symptoms , such as pain or swelling (or both), presence of sinus tract deep probing defects, or other adverse
