Hospitalized patients with schizophrenia had twice as many caries and extracted teeth, and five time less filled teeth than healthy people. The patient’s age and taking antiparkinsonics were established as predictors of the increased DMF index in hospitalized patients with schizophrenia.

Background/Aim. Many studies on oral health of psychiatric inpatients reported schizophrenia as the most common psychiatric disorder among their sample population. The available evidence suggests the higher prevalence and severity of periodontal disease among the psychiatric inpatients. The aim of this study was to evaluate periodontal health among the inpatients with schizophrenia and to consider possible risk factors for their current periodontal diseases. Methods. This cross-sectional study comprised 190 inpatients with schizophrenia at the Clinic for Psychiatric Disorders "Dr Laza Lazarevic" in Belgrade, and 190 mentally healthy patients at the Clinic for Periodontology and Oral Medicine, Faculty of Dental Medicine, University in Belgrade. The Community Periodontal Index for Treatment Needs (CPITN) and sociodemographic characteristics were registered in both groups as well as the characteristics of the primary disease among the inpatients with schizophrenia. Results. The patients in the study group had significantly higher scores of the CPITN (2.24 ± 0.98) than the patients in the control group (1.21 ± 1.10). Most of the patients in the study group had supra-, or subgingival calculi (46.8%), in contrast to the control group patients, who had in most cases gingival bleeding (45.8%). The periodontal pockets where detected in 35.8% of schizophrenic inpatients. The linear regression analysis showed that the gender and age were statistically significant predictors of the CPITN value among the inpatients with schizophrenia. Conclusion. The results of this study generally indicate the need for continuous research of psychiatric patients' oral health, in order to determine the modes of its improvement. Similar studies should elucidate significance of psychiatric patients' periodontal health and sensitize psychiatrists and psychiatric nurses to the oral problems of their patients.

Background / Aim. According to the World Health Organization (WHO), there is an increasing prevalence of mental disorders among children and adolescents worldwide. Previous studies have shown that people with mental disorders, regardless age, have an increased prevalence of dental caries due to several reasons. The aim of this study was to determine prevalence of dental caries in adolescents with mental disorders and to consider possible risk factors that might contribute to their current dental health status. Methods. The study was conducted as an observational cross-sectional study. The study group comprised 70 randomly selected hospitalized adolescents with mental disorders. The control group comprised 70 randomly chosen mentally healthy adolescents. They were matched to the study group by gender and age. All the participants were subjected to targeted dental examination according to criteria recommended by the WHO. Collection of data related to mental disorders of the study group was obtained from the patient's medical records. All collected data were organized and analyzed by descriptive statistical parameters and regression models. Results. Majority of the study group patients were diagnosed with schizophrenia, schizotypal and delusional disorders (F20-F29), as well as behavioral and emotional disorders usually occurring in childhood and adolescence (F90-F98). Almost 90% of them were treated with antipsychotics of the second generation-as monotherapy or in combination with first-generation antipsychotics. Adolescents with mental disorders had significantly more carious and extracted teeth and three times less filled teeth than mentally healthy adolescents in the control group. The mean value of the DMF index in the study group patients was also significantly higher than the mean value of DMF index in the control group subjects. Conclusion. It seems that mental disorder among adolescents mainly affects oral health indirectly, decreasing motivation of patients in maintaining oral hygiene.

Introduction Patients with schizophrenia are likely to constitute a high-risk group of individuals with respect to prevalence of oral diseases and they require special attention. Factors like nature of psychiatric disorders, length of stay and oral-side effects of psychotropic medications have been noted as contributors to poor oral health among institutionalized chronic psychiatric patients. Methods This cross-sectional study comprised 190 inpatients with schizophrenia at the Dr Laza Lazarevic Clinic for Mental Disorders in Belgrade, and 190 mentally healthy patients at the
