Representative radiographs as examples of unsatisfactory healing. Uncertain healing (Top Row): a maxillary central incisor was radiographically assessed as an example of ‘uncertain healing’ 1 year after EMS. (A) Immediate postoperative, (B) 1-year follow-up, and (C) diagram of apical healing used for classification, as described [18,19]. Unsatisfactory healing (Bottom Row): a mandibular lateral incisor was radiographically assessed as ‘unsatisfactory healing’ 1 year after EMS.
