Impact of the COVID-19 Pandemic on the Oral Health Workforce: A Multicenter Study from the Southern Region of Brazil.

The aim of this study was two-fold: (1) to describe the surveillance and biosafety measures adopted by dentists, dental hygienists, and dental assistants who worked in the Southern Region of Brazil and (2) to evaluate access to information in the context of the COVID-19 pandemic. This was a multicenter and cross-sectional design, using a self-applied and validated online questionnaire. The availability of health-care-related supplies and the adoption of biosafety measures recommended by the Technical Note of the National Health Surveillance Agency No.

Oral hygiene prior to cardiac surgery to prevent infections: Randomized clinical trial.

Context: It is not clear if an oral hygiene protocol to control biofilm applied before cardiac surgery can reduce infection rates.

Objective: We aim to verify the effectiveness of an oral hygiene protocol in reducing postoperative infections when compared to usual practices, in patients admitted to a cardiology unit, prior to cardiac surgery.

Design, Setting And Participants: Randomized, blind, controlled clinical trial, with 107 participants who expected to undergo cardiac surgery, randomized into two groups: Experimental Group (EG) standardized oral hygiene protocol (54) and Control Group (CG), usual practices performed in patients admitted (53).

[Obstacles to public governance and their influence on oral healthcare in the state of Santa Catarina, Brazil].

The study aimed to analyze public governance in the regionalized healthcare network in the state of Santa Catarina, Brazil, and its influence on decision-making in the organization of oral healthcare. This was an exploratory analytical study with a qualitative approach, with the methodology based on Grounded Theory. Thirty in-depth interviews were held with managers from the Regional Inter-Managers Commissions and Bipartite Commissions (CIR and CIB, respectively, in Portuguese), under the State Health Department, representatives from the State Health Councils, and administrators of specialized oral healthcare services, in two sample groups, in addition to non-participant observation in CIB meetings.

Teaching undergraduate geriatric dentistry in five South America countries.

Objective: This study aimed to qualitatively analyse undergraduate geriatric dentistry (GD) teaching characteristics identified by geriatric dentistry teachers and senior students in five South American countries.

Background: GD involves the knowledge and skills required to provide oral health care for older people.

Methods: Exploratory-descriptive research with a qualitative approach developed in the undergraduate context of public universities in Chile, Argentina, Brazil, Colombia and Peru.

Expression of stem cell markers Nanog and Nestin in lip squamous cell carcinoma and actinic cheilitis.

Unlabelled: Cancer stem cell (CSC) proteins have been observed in several lesions and are associated with tumor beginning, evolution, and resistance to treatment.

Objectives: To investigate the presence of NANOG, NESTIN, and β-tubulin in lip squamous cell carcinoma (LSCC), actinic cheilitis (AC), and normal epithelium (NE).

Materials And Methods: Thirty cases of LSCC, thirty cases of AC (both analyzed according to the WHO classification and AC according to the binary classification), and twenty cases of NE were submitted to an immunohistochemical study.

Untreated Dental Caries Is Associated with Reports of Verbal Bullying in Children 8-10 Years Old.

The objective of this research was to verify the association between verbal bullying and untreated dental caries. The present cross-sectional study had a representative sample of 1,589 children, aged 8-10 years, from public schools. Information on verbal bullying related to the oral condition was obtained through a questionnaire directed to the students.

Immunohistochemical expression of matrix metalloproteinase-1, matrix metalloproteinase-2 and matrix metalloproteinase-9, myofibroblasts and Ki-67 in actinic cheilitis and lip squamous cell carcinoma.

Matrix metalloproteinases (MMPs), myofibroblasts (MFs) and epithelial proliferation have key roles in neoplastic progression. In this study immunoexpression of MMP-1, MMP-2 and MMP-9, presence of MFs and the epithelial proliferation index were investigated in actinic cheilitis (AC), lip squamous cell carcinoma (LSCC) and mucocele (MUC). Thirty cases of AC, thirty cases of LSCC and twenty cases of MUC were selected for immunohistochemical investigation of the proteins MMP-1, MMP-2, MMP-9, α-smooth muscle actin (α-SMA) and Ki-67.
