Abstract
AIM Oral function in patients with schizophrenia has not been well-characterized. To address this, we performed a cross-sectional study of oral function in Japanese inpatients with schizophrenia. METHODS We measured oral function, including occlusal force, tongue-lip motor function, tongue pressure, and masticatory function in 130 Japanese inpatients with schizophrenia. We then compared the frequency of clinical signs of oral hypofunction among 63 non-elderly and 67 elderly inpatients with schizophrenia, as well as data from 98 elderly control participants from a previous Japanese study. RESULTS The frequency of reduced occlusal force was significantly higher in the elderly inpatients (76.2%) than in the non-elderly inpatients (43.9%) and elderly controls (43.9%). The frequency of decreased tongue-lip motor function in non-elderly inpatients (96.8%) and elderly inpatients (97.0%) was significantly higher than that in elderly controls (56.1%). The frequency of decreased tongue pressure in non-elderly inpatients (66.1%) and elderly inpatients (80.7%) was significantly higher than that in elderly controls (43.9%). Finally, the frequency of decreased masticatory function was highest in elderly inpatients (76.5%), followed by non-elderly inpatients (54.8%) and elderly controls (15.3%). CONCLUSION Oral function was decreased in both non-elderly and elderly Japanese inpatients with schizophrenia compared with elderly controls.

J Oral Rehabil 2024; 51:695-702.

Abstract
BACKGROUND Oral function deterioration attributed to ageing and medications is one of the main contributory factors of dysphagia. Therefore, oral health management is essential in older patients with schizophrenia. However, no previous studies have evaluated the oral function in patients with schizophrenia. OBJECTIVE We surveyed patients with schizophrenia to identify factors associated with ageing-related variations in oral function. METHODS This cross-sectional study included 34 male patients diagnosed with schizophrenia who were hospitalised at a psychiatric hospital between July and September 2021 and underwent a screening examination during dental care. The survey items included basic information, oral hygiene information, oral (oral diadochokinesis [ODK] and tongue pressure), physical function, and nutritional status. Thirty-six male community-dwelling older individuals were included as controls, and their outcomes were compared with those of patients with schizophrenia. RESULTS Compared with healthy older adults, patients with schizophrenia demonstrated significantly lower teeth numbers, ODK, and calf circumference (CC) (p < .05). Multiple regression analysis revealed that ODK was associated with age and schizophrenia (p < .05). Conversely, tongue pressure was associated with CC (p < .05), suggesting different factors' association with the parameters indicating decreased oral function. CONCLUSIONS Our study findings suggest that older patients with schizophrenia have decreased tongue pressure and generalised muscle mass, highlighting the need to manage oral function. Interventions for tongue pressure were more strongly associated with muscle mass and could be easier to manage than those with disease-dependent changes in ODK. TRIAL REGISTRATION Retrospectively registered.

Evaluation of brushing efficiency in reducing oral microbiota in mechanically ventilated patients admitted to an intensive care unit. Infect Prev Pract 2024; 6:100346. [PMID: 38380354 PMCID: PMC10877438 DOI: 10.1016/j.infpip.2024.100346] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Accepted: 01/17/2024] [Indexed: 02/22/2024] Open
Abstract
Background Patients admitted to the Intensive Care Unit (ICU) are at greater risk of developing nosocomial infections due to their investigations, treatment and changes in the immune system. One of the most prevalent nosocomial infections is respiratory tract infection, such as hospital acquired pneumonia and ventilator-associated pneumonia (VAP). The bacteria commonly found in the oral cavity in the hospital environment are Streptococcus viridians, Staphylococcus aureus, Pseudomonas aeruginosa, Enterococcus spp., and Klebsiella pneumoniae. There is a need to test and define appropriate standard protocols for oral hygiene in patients undergoing mechanical ventilation in ICUs through the intervention of a dental specialist, preventing the proliferation of microorganisms into the respiratory tract, thus reducing hospitalization time, the use of antibiotics, and increased morbidity/mortality. Objective: This study aimed to evaluate the effectiveness of dental brushing in the reduction of the pathogenic buccal microbiota associated with mechanical ventilation in patients admitted to the Evangelical Hospital from Londrina, Paraná, Brazil. Methodology The sample consisted of 90 patients (of both sexes), mean age of 65 years, under mechanical ventilation by orotracheal tube and tracheostomized patients, without suspected or confirmed diagnosis of pneumonia. Patients were randomized ∗∗∗. Results Results showed that oral hygiene using a toothbrush by suction, with chlorhexidine gel 0.12% (Group B), was more effective than conventional hygiene using gauze soaked with chlorhexidine 0.12% (Group A) in reducing pathogenic buccal microbiota. Conclusions There was a reduction of the pathogenic buccal microbiota in mechanically ventilated patients receiving oral hygiene using a toothbrush by suction with chlorhexidine gel 0.12% (Group B).

Abstract
Schizophrenia is a psychiatric disorder that makes patients incompetent to perform day-to-day activities due to their progressing mental illness. In addition to disturbances with thoughts, behavioral changes, and impaired cognitive functions, oro-systemic health also becomes compromised. Even though the population with schizophrenia is primarily made up of older people, little is known about this group's oral health treatment. The present review explores the relationship between oral healthcare and elderly patients with schizophrenia. Our literature search included databases, like PubMed, Embase, and Google Scholar, for appropriate and evidence-based information. Preventive and management strategies outlined in the included articles and future research perspectives in this field are discussed. To the best of our knowledge, this is the first review that looked at dental care and related characteristics in older schizophrenia patients. The findings highlight the necessity for targeted dental interventions to address the dental health challenges faced by this vulnerable population. Integrating dental health into the overall medical management of elderly individuals with schizophrenia is crucial. Although specific therapies remain limited, the emphasis is on preventive dentistry to reduce the occurrence and progression of oral diseases in this group.

Abstract
Background/purpose: Dentists sometimes struggle with treating patients with unexplained symptoms, known as oral psychosomatic disorders, that do not improve with conventional treatment. Oral psychosomatic disorders do not fit the definition of psychosomatic diseases in internal medicine. To ensure appropriate dental treatment, it is important for general dentists to distinguish between oral psychosomatic disorders and psychosomatic diseases. However, relevant evaluation methods have not yet been developed. The DMFT index is widely used as an indicator of the caries status. The purpose of this study was to compare the DMFT index scores of patients with oral psychosomatic. Materials and methods The DMFT scores of 2202 patients with oral psychosomatic disorders, 145 psychiatric inpatients, and 3940 general dental patients were statistically compared. The DMFT of patients with oral psychosomatic disorders was further compared based on the presence or absence of psychiatric history and disease. Results The median DMFT scores of oral psychosomatic disorder patients, psychiatric inpatients, and general dental patients were 16, 22, and 10, respectively, showing a significant difference. No significant differences were found in the DMFT scores based on the presence or absence of psychiatric history in oral psychosomatic disorder patients. Conclusion The intraoral environment of patients with oral psychosomatic disorders was worse than that of general dental patients but better than that of psychiatric inpatients. General dentists could suspect psychiatric and oral psychosomatic disorders based on the state of patients' oral environment.
