Proponents of NICO recommend decortication (surgical removal of a section of the cortical plate, originally described as a treatment for osteomyelitis of the jaws) and curettage of the necrotic bone from the cavitation, and in some reported cases, this has relieved the chronic pain. However, NICO appears to show a tendency to recur and develop elsewhere in the jaws. The American Association of Endodontists Research and Scientific Affairs Committee published a position statement on NICO in 1996, stating:

"Most affected sites with a postoperative NICO diagnosis have been in edentulous areas [where the teeth have been lost]. However, some patients with long, frustrating histories of pain associated with endodontically treated teeth have been presented the treatment option of tooth extraction followed by periapical curettage in an attempt to alleviate pain. The American Association of Endodontists cannot condone this practice when NICO is suspected. Because of the lack of clear etiological data, a NICO diagnosis should be considered only as a last resort when all possible local odontogenic causes for facial pain have been eliminated. If a NICO lesion is suspected in relation to an endodontically treated tooth, if possible, periradicular surgery and curettage should be attempted, not extraction. In addition, the practice of recommending the extraction of endodontically treated teeth for the prevention of NICO, or any other disease, is unethical and should be reported immediately to the appropriate state board of dentistry." Atypical trigeminal neuralgia
Some suggest that AFP is an early form of trigeminal neuralgia.
Epidermolysis bullosa simplex (EBS) is a disorder resulting from mutations in the genes encoding keratin 5 or keratin 14.: 598 Blister formation of EBS occurs at the dermoepidermal junction. Sometimes EBS is called epidermolytic. Cause
Absence of keratin-5,14 since birth. Diagnosis
Classification
Epidermolysis bullosa simplex may be divided into multiple types:

Management
No cure for EB
Treat symptoms
Protect skin, stop blister formation, promote healing
Prevent complications
Necessary treatment: use oral and topical steroid for healing and prevent complication
Maintain cool environment, avoid overheating and decreases friction
