The main objectives of treatment is pain relief, preserving patients remaining dentition, and to treat and preserve the patients occlusal vertical height.Many factors are to be considered to decide on treatment options such as the classification and severity of AI, the patients social history, clinical findings etc. There are many classifications of AI but the general management of this condition is similar.Full-coverage crowns are sometimes being used to compensate for the abraded enamel in adults, tackling the sensitivity the patient experiences. Usually stainless steel crowns are used in children which may be replaced by porcelain once they reach adulthood. These aid with maintaining occlusal vertical dimension. Aesthetics may be addressed via placement of composite or porcelain veneers, depending on patient factors e.g. age. If the patient has primary or mixed dentition, lab-made composite veneers may be provided temporarily, to be replaced by permanent porcelain veneers once the patient has stabilized permanent dentition. The patients oral hygiene and diet should be controlled as well as they play a factor in the success of retaining future restorations.In the worst-case scenario, the teeth may have to be extracted and implants or dentures are required. Loss of nerves in the affected teeth may occur. Epidemiology
The exact incidence of amelogenesis imperfecta is uncertain. Estimates vary widely, from 1 in 700 people in northern Sweden to 1 in 14,000 people in the United States.
March fracture, is the fracture of the distal third of one of the metatarsals occurring because of recurrent stress. It is more common in soldiers, but also occurs in hikers, organists, and people whose duties entail much standing (such as hospital doctors). March fractures most commonly occur in the second and third metatarsal bones of the foot. It is a common cause of foot pain, especially when people suddenly increase their activities. Signs and symptoms
The onset is not dramatic. When the boot or shoes are taken off, there is a cramp-like pain in the affected forefoot, and moderate local edema appears on the dorsal aspect. On moving each toe in turn, that of the involved metatarsal causes pain, and when the bone is palpated from the dorsal surface, a point of tenderness is found directly over the lesion. Radiography at this stage is negative, but the condition is diagnosed correctly by military surgeons without the aid of x-rays. In civil life, it is seldom diagnosed correctly for a week or two, when, because of lack of immobilization, there is an excessive deposit of callus (which may be palpable) around the fracture. Diagnosis
X-ray is seldom helpful, but a CT scan and an MRI study may help in diagnosis. Bone scans are positive early on. Dual energy X-ray absorptiometry is also helpful to rule out comorbid osteoporosis. Differential diagnosis
Acute metatarsal fracture
Hallux rigidus
Jones fracture
Sesamoid stress fracture
Acute sesamoid fracture
Proximal fifth metatarsal avulsion fracture

Treatment
The first line treatment should be reduction of movements for 6 to 12 weeks.
