Chairside endodontic management of a child with fibrodysplasia ossificans progressiva

ABSTRACT

Fibrodysplasia ossificans progressiva (FOP) is an exceptionally atypical genetic disorder characterized by heterotopic bone formation within skeletal muscles, ligaments, tendons, and other connective tissues that affects one in 2 million people. A 4-year-old girl with FOP was referred to our practice with complaints of pain and discomfort in both sides of the lower jaw. Clinical examination revealed deep multiple caries and buccal gingival abscess in relation to multiple teeth. Endodontic care and conservative dental procedures were planned and performed chairside after a detailed discussion with FOP medical and dental experts. Very brief dental appointments were conducted with breaks to prevent muscle fatigue. No usage of regional anesthesia or dental dam clamps was done. The patient and her parents were counseled for oral hygiene maintenance, and periodic topical fluoride treatments were performed during successive follow-up appointments. The child is followed for 34 months post-treatment. The dental treatment modifications implemented for the present case were enough to institute good oral health and to prevent the creation of heterotopic ossifications in the maxillofacial region.
