Micro-osteoperforation (MOP) is a newly developed technique reported to accelerate orthodontic tooth movement.
The following case report discusses a peripheral ossifying fibroma (POF), as a reactive gingival nodule that developed eight weeks after a patient underwent transmucosal MOP at multiple sites in the mandible during orthodontic treatment.
The MOP procedure is a relatively new approach applied to orthodontics that may induce gingival reactive nodules. Clinicians should be aware of this possible sequela and inform patients of the potential risk.
