Oral mucosal wound healing: A photograph‐based prospective study

Oral mucosa exhibits minimal scar formation compared with other tissues. Studies evaluating the healing dynamics of the various intraoral tissue types remain limited. This prospective study investigates the healing characteristics of keratinized gingiva and non-keratinized alveolar mucosa, by focusing on scar formation following piezocision. Complete wound closure was observed at all sites 1 week after surgery. More than half of the piezocisions produced no visible scarring. Notably, even though the incisions penetrated the full thickness of the tissue and involved perforation of the vestibular cortical bone, no significant scarring was observed. However, increased scar visibility was noted in patients with pigmented gingiva. The healing results appear to vary according to anatomical regions.
