Full mouth rehabilitation in a medically compromised patient with fluorosis.

Severely worn out dentition needs to be given definite attention as it not only affects aesthetics but can also cause psychological distress to the affected individual. It can cause chewing difficulty, temporomandibular joint problems, headaches, pain and facial collapse. Before any attempt to restore severely worn dentition, aetiology of excessive tooth wear should be established. Severe wear can result from chemical cause, mechanical cause or a combination of various causes. Dental fluorosis can also result in severe wear of teeth. Teeth sometimes become extremely porous and friable with a mottled appearance ranging from yellow to brown-black. There occurs loss of tooth substance and anatomic dental deformities resulting in un-aesthetic dentition requiring full mouth rehabilitation. Here a similar case of full mouth rehabilitation of severely worn dentition due to dental fluorosis in a 27-year-old patient is presented. This case report conjointly presents the uncommon association of diabetes insipidus with dental fluorosis. Diabetes insipidus through its characteristic symptom of polydipsia can result in intake of more than permitted dose of fluoride thus causing dental fluorosis. In literature only few cases have been reported of dental fluorosis in association of diabetes insipidus. Full mouth rehabilitation of the patient was successfully accomplished through well-planned systematic approach to simultaneously fulfill aesthetic, occlusal and functional parameters.
