Oral health in schizophrenia patients: A French Multicenter Cross-Sectional Study.

The aim of this study was to assess the oral health status of a sample of patients with schizophrenia (PWS) in Côte d'Or region (France) and to determine the factors associated with dental status. A multicenter cross-sectional descriptive study was performed. PWS were selected using a random stratified method. Dental status was investigated using the Decayed, Missing, or Filled Teeth (DMFT) index, based on 32 teeth. The Simplified Oral Hygiene Index (OHI-S), the Xerostomia Index (XI) and the Global Oral Health Assessment Index (GOHAI) for Oral Health-related Quality of Life (OHrQoL) were recorded. Among the 302 persons identified, 109 were included (acceptance rate was 49.1%). Of these, 61.5% were men. The mean age was 46.8 years±12.0 years. The majority (78%) had completed a secondary education (SE). The mean duration of mental illness (DMI) was 17.9±9.4 years, and 55.5% were taking drugs. The mean DMFT was 16.6±8.1. There was a significant relationship between age, SE, oral health variables, medical conditions and OHrQoL. PWS describe a poor OHrQoL. The dental and hygiene index scores are poor. We observed a lack of brushing and of dental visit for these persons and a gap in oral health between PWS and general population.
