Riga–Fede disease (RFD) is a rare and benign mucosal condition,[1] characterized by a tongue ulcer that is frequently brought on by traumatizing injuries sustained from repeatedly moving the tongue back and forth over the mandibular anterior incisors.[2]
Signs and symptoms
Clinically, it typically manifests as a tongue-localized ulcer (60 percent of lesions), though it can also affect the lip, palate,
Causes
RFD is most frequently linked to the emergence of the natal-neonatal teeth in newborns[4] or the primary lower incisor in older infants.[5]
Diagnosis
Histopathologically speaking, RFD is characterized by mucosal areas that are ulcerated, granulation tissue present, and a mixed inflammatory infiltrate that is abundant in mast cells, macrophages, lymphocytes, and eosinophils.[6]
Treatment
The lesion can be removed, the sharp incisal edges can be smoothed, or the tooth's sharp edges can be rounded with composite increments. The latter is where mild to moderate ulceration can occur. Teeth extraction may be helpful if the ulceration is large and preventing the patient from eating.[7]
