Understanding the Oral Health Status and Factors Affecting Poor Oral Health in People Living With Severe Mental Illness: A Cross-Sectional Study.
Article in Australian dental journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesTo assess the oral health status of patients with severe mental illness visiting the Collaborative Centre for Cardiometabolic Health in Psychosis clinics and examine the effect of demographic, medical and social factors on Oral Health (OH).
methodsThe cross-sectional study included adults aged 18-65 years with severe mental illness who attended the clinics in Sydney, Australia between June 2016 and December 2020. As part of the OH assessment, information about their oral hygiene behaviours was recorded and participants underwent dental examination to assess their dental status.
resultsThe majority of the 845 patients were male (63%), with a mean age of 43.4 years and a diagnosis of Schizophrenia (61%). Co-morbidities included dyslipidaemia (93.3%), overweight/obesity (81%), and hypertension (47%). Gingival inflammation was noticed in 80% of participants. Caries experience was high, with 44% having active tooth decay requiring restoration or extraction. Age, smoking, schizophrenia, depression and cardiometabolic conditions like diabetes and hypertension were significantly associated with caries. Gingival inflammation was significantly associated with psychiatric diagnosis and antipsychotic medications, male gender, smoking and diabetes.
conclusionsPeople with severe mental illness have a high prevalence of dental caries and gingival inflammation. A strong association between dental diseases and demographics as well as cardiometabolic conditions emphasises the need for a multipronged approach to improve the overall health outcomes of people with severe mental illness.
