This research project was funded by the Agence Régionale de Santé de Bourgogne (ARS). Oral health in schizophrenia patients: a French multicenter cross-sectional studyObjective: 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. Material and Methods: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.Results: 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.Conclusions: 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.La santé bucco-dentaire des patients schizophrènes: une étude française transversale multicentrique Objectif : Le but de cette étude était d'évaluer l'état de santé bucco-dentaire d'un échantillon de patients atteints de schizophrénie (PS) en Côte d'Or (France) et de préciser les facteurs associés à la santé bucco-dentaire.Matériel et méthodes : Une étude descriptive transversale multicentrique a été réalisée.
