Introduction: Parafunctional habits are behaviors that are not part of the functional and physiological needs of the components of the stomatognathic system and can be indicative of stress, anxiety and/or depression. They can generate complications during and after oral and maxillofacial surgeries. Objective: To estimate the prevalence of parafunctional habits and psychological status in patients undergoing oral and maxillofacial surgeries, their associated factors and their interference with the course of the dental procedure. Material and Method: The study is a field research, characterized by being observational, with a cohort design, with a quali-quantitative approach. A stratified probability sampling was carried out in patients from the CEO of surgery at Asces-Unita and the Clínica Ortoestetica de Toritama, to verify if there are factors in public and private care that may interfere during and after oral and maxillofacial surgeries.The research instruments were questionnaires based on the Beck Depression. Inventory-BDI, the Beck Anxiety Inventory-BAI, the LIPP Stress Symptoms Inventory. Results and Discussion: 116 patients were interviewed, among which 88 (75.86%) are from the Surgery CEO of the Centro Universitário Tabosa de Almeida-ASCES UNITA and 28 (24.13%) are from the Orthoesthetic Clinic of Toritama/PE. Of those interviewed, 64 (55.17%) patients had some parafunctional habit, 61 (52.58%) patients had some psychological disorder and 68 (58.62%) patients had some surgical complication. Factors such as stress, anxiety and depression can impair the surgical process as well as the patient’s recovery, generating a greater probability of episodes of high blood pressure, more intense bleeding in surgeries and a reduction of immune resistance, as well as leading to disorders psychosomatic. Conclusion: Thus, after crossing the variables, it was confirmed that there is a relationship between surgical complications with parafunctional habits and psychological disorders.

Introduction: Gram-negative bacteria are the main cause of infections ranging from pneumonia to bloodstream infection. In the oral cavity, there may be microorganisms associated with systemic and opportunistic infections. In addition, the irrational use of antibiotics related to odontogenic infections will promote the colonization of these microorganisms and contribute to antimicrobial resistance. Objective: To investigate the presence of multidrug-resistant gram-negative bacteria in the oral cavities of patients in a dental clinic. Material and Methods: The characteristic of the study is to be observational, with a laboratory and cross-sectional design. A sample of 60 patients from all Asces-Unita dental clinics was used. Samples were obtained through a swab smear on the patient’s oral mucosa. The technique for laboratory analysis follows the methodology of Winn et al. Antibiogram was performed according to the Kirby-Bauer technique. The antibiotics used followed the indications provided by CLSI 2021 and BrCAST 2021. This is a study using descriptive statistics. Results and Discussion: From 60 bacterial isolates obtained, 15 samples of gram-negative bacteria were obtained, mostly Pseudomonas aeruginosa 6 (40%), Klebsiella pneumoniae 5 (33.3%), Enterobacter sp 1 (6.66%), Citrobacter sp 1 (6.66%) and Proteus vulgaris 2 (13.33%). Multidrug resistance was observed in 20% of Klebsiella pneumoniae cases, in 83.3% of Pseudomonas aeruginosa cases, in 100% of Proteus vulgaris cases. Nowadays, antimicrobial resistance is the main problem in Intensive Care Units (ICU), the excessive use of antibiotics in communities and hospitals directly contributes to the development of bacterial resistance.Conclusion: Multidrug-resistant gram-negative bacteria were isolated in the oral cavity of patients seen at a dental clinic. In view of this finding, it is important to review the antibiotic treatment used to combat infections caused by gram-negative bacteria, based on laboratory identification and the use of an antibiogram.
