The aim of the study is to describe the oral health status of patients suffering from schizophrenia and schizoaffective disorders in a psychiatric institute in France.

Schizophrenia concerns 21 million people in the world and 600 000 in France according to the World Health Organization. This pathology decreases the patient's quality of life and one patient out of two will try to commit suicide and 10% will die. Oral health is an important factor for general well being. The litterature shows that schizophrenic patients tend to visit less dental surgeries than the general population. Patients will often visit the surgery in emergency and dentist often choses to extract instead of a restorative solution. Thus, schizophrenic subjects are 3,4 more likely to become edentulous compared to the general population.

This is a cross-sectional epidemiological study on patients suffering from schizophrenia and and schizoaffective disorders in a psychiatric institution. A dental assessment will be conducted to provide clinical data on oral health. (DMFT, hygiene, mouth dryness, prosthesis) and a survey of their diet, medication, oral quality of life, social security coverage and patients view regarding dental care (Anxiety and Healthcare renunciation).

This is an observational study (oral examination and survey), so no treatment will be compared. The oral health status will be evaluated during one single oral examination and survey during the patient's stay at hospital.
