The Relationship between Professional Variables and Burnout Syndrome in Brazilian Dentists during the COVID-19 Pandemic.

Burnout syndrome (BS) is a highly prevalent occupational disease among dentists who, during the COVID-19 pandemic, have been at greater risk of contracting the disease, generating stress and distancing. The aim of this study was to assess the association of social conditions, professional factors and perceptions of COVID-19 with Burnout Syndrome. This was a cross-sectional study of 302 Brazilian dentists working in the clinical and private sectors. The professionals completed the Oldenburg Burnout Inventory online and answered sociodemographic and professional questions and questions related to their perception of the pandemic. Poisson regression with unadjusted and adjusted robust variance was used to estimate the association between burnout syndrome (dependent variable) and the independent variables. The presence of BS was strongly associated with age, training in a private institution, professionals who claimed to have sufficient protective knowledge and fear of being contaminated by SARS-CoV-2 during patient care (p < 0.05). The findings of this study show that there has been an impact of the COVID-19 pandemic on the occurrence of Burnout syndrome in dentists, especially, those who worked in the public sector and those who were afraid to work with other health professionals.

Salivary Adiponectin and Albumin Levels on the Gingival Conditions of Patients Undergoing Bariatric Surgery: A Cohort Study.

This study analyzed the salivary proteomics, adiponectin and albumin, related to weight loss and periodontitis in patients undergoing bariatric surgery. This study included fourteen patients with morbid obesity (body mass index, BMI > 40 kg/m2) who underwent bariatric surgery Roux-en-Y gastric bypass (RYGB) in System Health Public in Brazil. Data on demographic and anthropometric measures were extracted from medical records preoperatively and 6 and 12 months post-surgery. The variables assessed were: probing pocket depth (PPD), clinical attachment loss (CAL), bleeding on probing (BOP), and stimulated whole-mouth saliva. In this study, saliva samples were analyzed by electrophoresis and immunoblotting. The ELISA kit was used to measure the MMP8 levels to determine potential markers for obesity. Adiponectin and albumin levels were also evaluated. Weight loss was associated with significant changes in patients' periodontal clinical data. Although 7 out of 10 periodontal patients showed an increase in salivary adiponectin levels after root planning treatment, when analyzed by Western blotting, the increase was not statistically significant (21.1 ± 4.8 to 26.3 ± 9.4 arbitrary units, p > 0.99). There was no correlation between albumin levels and salivary adiponectin pre-surgery, nor 6 months or 12 months after surgery. Weight loss was not improved by low-grade inflammation in bariatric patients, since albumin levels were similar between periods. Periodontitis is an inflammatory disease that is modulated by several factors, among which adiponectin plays an important role for the treatment of periodontal disease.

Assessment of Psychosocial Factors in Brazilian Dentists Facing Risk of SARS-CoV-2 Infection in the Public and Private Sectors.

Dentists are at high risk of SARS-CoV-2 infection due to their close proximity to patients. Thus, the fear of contamination or spreading the virus to family members, coupled with financial need, can lead professionals to experience significant overload and psychological suffering. We investigated the perceptions of dental professionals in the public and private sectors regarding fear and anxiety related to patient care and the risk of infection in the face of the COVID-19 pandemic. Based on the previous literature, we interviewed 302 dentists online using sociodemographic and professional questions. Among the professionals evaluated, 80.8% had suspended their activities for some time, 74.8% were afraid of infection at work, 86.1% feared transmitting the virus to their families, 30.1% had already been infected, 54% felt afraid when they heard the news of death caused by SARS-CoV-2, and 63.9% reported having the protective knowledge necessary to avoid infection. Dentists who worked only in the public sector and those who worked in both sectors were more afraid of being infected than professionals who worked only in private offices. Our results highlight the impact of the COVID-19 pandemic on emotional health in dentists. This study highlights the need for more support in the psychosocial field to enable dentists to overcome difficulties and maintain the provision of good dental care for the population. Continuing education should update professions with the requisite scientific and clinical knowledge to face the pandemic and achieve greater reflection on their role within this new context to improve their professional and emotional performance.

Need of Dental Prosthesis in Older People and the Offer of Specialized Care in the Unified Health System, Brazil

Objective: To analyze the offer of dental prosthesis by Centers of Dental Specialties (CEO) considering the need by individuals aged 65-74 years in state capitals and other regions of the country. Material and Methods: The study was conducted with data from the external evaluation of the Improving Access and Quality Program (AVE/PMAQ CEO) and with data from the SBBRASIL 2010 project. AVE / PMAQ CEO is an evaluative investigation using a cross-sectional research design, performed in all CEOs of Brazil, totaling 932 services evaluated. The analysis of data and distribution of CEOs that offered dental prosthesis was described by maps, using TabWin (DATASUS) and quantitative description of the following variables: need for total and partial dentures, CEO, Regional Prosthodontic Laboratories (RLDP), average monthly number of delivered prostheses and the proportion of capitals with RLDP, number of CEOs, RLDP and prostheses delivered per 100,000 inhabitants in state capitals and other regions. Results: Of the 5,570 municipalities in the country, 780 have CEO, mainly located on municipalities with larger populations. Most CEOs were located in the northeastern (38.3%) and southeastern regions of Brazil (36.2%) with the northern and mid-western regions presenting the lowest absolute number of units. Low offer of prostheses was observed, considering the high need of dentures, as well as an unequal distribution among Brazilian regions. A high percentage of older adults aged 65-74 years require total (74.6%) or partial (99.8%) prosthetic rehabilitation, more critical situation is observed in the northern and northeastern regions. Conclusion: The provision of dental services in CEOs is still limited and unevenly distributed, especially for PPR, compromising the universality and integrality of oral health care.

Amazonian delicacy tucupi is as erosive as a cola-based soft drink.

OBJECTIVE: Acidic diets are advocated as main risk factor for tooth erosion, which could be prevented, or at least controlled, if patients were early advised. It is important to identify, hence, if possible dietary constituents regionally consumed on large scale, such as tucupi, a low-pH yellowish-green color and strong flavor delicacy made from the juice of a bitter cassava, may explain its occurrence in specific patient groups. This cross-over in situ/ex vivo study evaluated tucupi's ability to promote erosion of bovine enamel by assessing its percentage of surface microhardness change (%SMHC), taking a cola-based soft drink and human saliva as positive and negative controls. DESIGN: For three 7-days spaced out legs of 7 days each, nine volunteers wore palatal devices with three bovine enamel blocks, which were challenged with one of the following solutions: TUC-tucupi (n=27); COL-cola-based soft drink (n=27); SAL-saliva (n=27). Erosive challenges were performed extra-orally (4×/day) by dropping TUC or COL at room temperature on specimens. After 5min, palatal devices were replaced into the mouth. SAL permanently acted as the negative control while volunteers solely wore the device. One-way ANOVA followed by Tukey's post-hoc tests (α=0.05) were applied. RESULTS: TUC promoted an enamel %SMHC (-21.56±10.08(a)) similar than that promoted by COL (-18.19±12.99(a); p=0.275), which were both significantly higher than that promoted by SAL (-1.86±13.65(b); p<0.0001). CONCLUSIONS: Besides the most worldwide appreciated cola-based soft drink, the greatly consumed Amazonian delicacy tucupi can be considered a potential risk factor for tooth erosion.
