Introduction/Objective The objective of the study was to investigate whether there are differences in therapeutic effect between initial treatments of chronic periodontitis [scaling and root planning (SRP)] alone and SRP in conjunction with injectable platelet-rich fibrin (I-PRF) application, comparing clinical parameters after three months. Methods Twenty-four patients with chronic periodontitis who had at least two sites with probing pocket depth (PPD) ≥ 5 mm on contralateral side participated in the study. Using a split-mouth design, the patients were treated with SRP + I-PRF (study group) or SRP only (control group). The clinical parameters, clinical attachment level (CAL), gingival margin level (GML), PPD, bleeding on probing, and plaque index, were recorded on both sides. Results Compared to baseline, both treatment modalities demonstrated an improvement in investigated clinical parameters. The mean value of CAL was reduced from 1.97 ± 0.75 (0.25-3.31) to 1.07 ± 0.44 (0.12-1.78) in the study group, whereas it decreased from 1.81 ± 0.66 (0.42-2.96) to 1.48 ± 0.55 (0.22-2.30) in the control group. Similarly, the corresponding values for GML and PPD showed statistically significant difference between the groups (p = 0.040 and p = 0.006, respectively). Conclusion Regardless the limited number of patients in the study, initial periodontal therapy in conjunction with injectable platelet-rich fibrin proved to display significant improvement in all clinical parameters compared to initial periodontal therapy alone.

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.

World Health Organization (WHO) declared the COVID-19 outbreak a public health emergency of international concern. Mental health strategies implemented due to the coronavirus epidemic must include the assessment of mental health status of people in different subpopulations influenced by the COVID-19 outbreak, identifying persons who are at high risk of manifesting behavior disorders, suicide attempt, and aggression in aim of providing appropriate mental health care interventions for those in need. The target population of these mental health strategies is categorized in four different groups: the most vulnerable people with mental health problems, isolated people with symptoms of atypical acute respiratory infection, individuals who have been in close contact with the previous two categories, and people affected by the preventive and restrictive measures.

SummaryPatients with schizophrenia, especially during period of their hospitalization, are likely to constitute a high-risk group of individuals with respect to prevalence of oral diseases. Several factors are mentioned in the manuscript that may contribute to the finding of increased prevalence of oral diseases in patients with schizophrenia. Unfortunately, some of these can be attributed to dental profession; these patients are sometimes deprived of dental service as they cannot afford the treatment due to its cost and they are even neglected sometimes by dental professionals. The idea of providing oral health care in the environment of specialized health care institutions, such as psychiatric hospitals, during periods of hospitalization, is especially emphasized.

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.
