Oral Health and Wilson's Disease: SOMAWI

Study Overview
=================
Brief Summary
-----------------
Patients with Wilson disease have poorer dental and periodontal health and a have lower oral quality of life than control patients. Patients with a neurological form would also more frequently present limitations in the function of the masticatory apparatus. Systemic treatments for Wilson disease are associated with lesions of the oral mucosa. Analysis of copper level in saliva could testify to the effectiveness of copper depletion in treated patients The main objective is to compare the state of dental health between: patients with Wilson disease in the hepatic form and patients with the neurological form, and a population of controls.

Detailed Description
-----------------
The comparaison between the three groups is based on evaluation criteria wich is CAOD index of caries severity (developed by Klein and Palmer in 1940) counting the number of permanent teeth with caries (evolving to include non-cavitary caries) (C), absent due to caries (A) and filled (O) in an individual. The maximum score is 28 (third molars are not taken into account). The index is obtained from clinical examination and panoramic dental imaging.
