This cross-sectional study aims to describe the dental caries experience, treatment needs, and experience of dry mouth of 191 long-term psychiatric inpatients in Singapore. Medical history, dental caries experience [represented by the Decayed Missing or Filled Teeth index (DMFT)], salivary flow, and treatment needs were recorded. Information on brushing, pain (when eating), and xerostomia was gathered. Bivariate analysis was used to examine the associations of DMFT, saliva flow, the presence of salivary gland hypofunction (SGH), and xerostomia. Simple linear regression was used to examine the association between SGH and DMFT. The sample comprised 143 men (74.9%) and 48 women (25.1%), aged 24 to 80 years old. 169 patients (88.5%) had schizophrenia. DMFT ranged from 0 to 32, with a mean of 21.6 (SD 9.7). Mean DMFT scores were significantly higher among males and older patients. 77 of 176 patients (43.8%) were found to have SGH. SGH was associated with a higher mean DMFT. Those taking classical antipsychotics and anticholinergics had significantly lower mean saliva flow and tended to have SGH. 107 of 165 patients (64.8%) were found to experience xerostomia. Long-term psychiatric inpatients in Singapore have poor oral health, unmet treatment needs, and suffer from dry mouth.
