Anti-Inflammatory, Antimicrobial, Antioxidant and Photoprotective Investigation of Red Propolis Extract as Sunscreen Formulation in Polawax Cream.

Many activities have been described for propolis, including, antiviral, antibacterial, antifungal, anti-inflammatory, immunoregulatory, antioxidant and wound healing properties. Recently, propolis has been highlighted due to its potential application in the pharmaceutical and cosmetic industries, motivating a better understanding of its antioxidant and anti-inflammatory activities. Propolis and its main polyphenolic compounds presented high antioxidant activity, and effectiveness as broad spectrum UVB and UVA photoprotection sunscreens.

Disinfectant effects of Brazilian green propolis alcohol solutions on the Staphylococcus aureus biofilm of maxillofacial prosthesis polymers.

Statement Of Problem: Brazilian green propolis may be an alternative product that reduces the development of a microbial biofilm on the polymers used for maxillofacial prostheses. However, its effects as a disinfectant have not been fully established.

Purpose: The purpose of this in vitro study was to investigate the effects of Brazilian green propolis alcohol solutions against the Staphylococcus aureus biofilm on polymers used in maxillofacial prostheses, the maxillofacial silicone elastomer (MDX4-4210), and specific acrylic resins for ocular prostheses.

Radiation-induced Oral Mucositis in Brazilian Patients: Prevalence and Associated Factors.

Unlabelled: Aim: To determine the prevalence of radiation-induced oral mucositis (OM) and associated factors.

Patients And Methods: A cross-sectional retrospective study was performed at a reference dental care center. The medical records of patients submitted to radiotherapy for the treatment of head and neck cancer were used to collect clinical and demographic variables.

Oral candidiasis: A retrospective study of 276 Brazilian patients.

Background: Although oral candidiasis (OC) is a very common fungal infection of oral cavity, clinical features of affected patients and their demographic profile are not well documented.

Objective: The objective of the study was to assess the demographic profile of patients diagnosed with OC and its clinical features in an import Brazilian center of oral and maxillofacial pathology.

Materials And Methods: A retrospective study consisted of 276 patients diagnosed with OC by cytopathology Periodic Acid-Schiff (PAS) staining, during the period of 20 years.

The anti-caries activity and toxicity of an experimental propolis-containing varnish.

We investigated the anti-caries effects of an experimental propolis varnish in vivo, and further tested its toxicity against fibroblasts. Fifty-six SPF female Wistar rats were infected with Streptococcus mutans UA159 (SM) and allocated into four groups (n = 14/group): G1, propolis varnish (15%/PV); G2, chitosan varnish (CV/vehicle); G3, gold standard (GS/Duraphat®); and G4, untreated. The animals received a single varnish application on their molars and were submitted to a high cariogenic challenge (Diet-2000, 56% sucrose, and 5% sucrose-added water, ad libitum) for 4 weeks.

Oral paracoccidioidomycosis: Retrospective analysis of 55 Brazilian patients.

Paracoccidioidomycosis (PCM) is a rare fungal infection in the world, but endemic and acquired exclusively in Latin America, with the highest prevalence in South America and Brazil, particularly. Changes in oral cavity are common and constitute the first clinical manifestation in many patients. The aim of this study was to describe the prevalence of oral PCM and analyse the profile of the disease and patients.

Clinical Evidence of the Efficacy of a Mouthwash Containing Propolis for the Control of Plaque and Gingivitis: A Phase II Study.

The aim of this study was to evidence the clinical efficacy of an alcohol-free mouthwash containing 5.0% (W/V) Brazilian green propolis (MGP 5%) for the control of plaque and gingivitis. Twenty five subjects, men and women aging between 18 and 60 years old (35 ± 9), were included in a clinical trials phase II study who had a minimum of 20 sound natural teeth, a mean plaque index of at least 1.

In vitro antimicrobial activity of Brazilian medicinal plant extracts against pathogenic microorganisms of interest to dentistry.

This study evaluated the susceptibility of oral pathogenic microorganisms Candida albicans, Streptococcus mutans, Staphylococcus aureus, and Aggregatibacter actinomycetemcomitans to Brazilian medicinal plant extracts of Schinus terebinthifolius (aroeira), Croton campestris (velame), Lafoensia pacari (pacari), Centaurium erythraea (centáurea), Stryphnodendron adstringens (barbatimão), and Anacardium humile (cajuzinho-docerrado), as compared to standardized antimicrobial agents (nystatin, chloramphenicol and tetracycline hydrochloride). Ethanol, hexane and butane fractions from stem barks, rinds, leaves, and/or roots were extracted and tested. Antimicrobial diffusion agar test and MIC were performed according to CLSI.

Candida oral colonization and infection in Brazilian patients undergoing head and neck radiotherapy: a pilot study.

Objective: The aim of this study was to verify the profile of Candida species responsible for colonizing and infecting the oral cavity of Brazilian patients undergoing radiotherapy (RT).

Study Design: Saliva samples were collected from 21 patients before, during, and immediately after RT. Each sample was distributed in agar Sabouraud dextrose/chlorophenicol and incubated at 37 degrees C for 18 hours.

Odontogenic tumors: a study of 340 cases in a Brazilian population.

Background: The aim of this study was to determinate the relative frequency of odontogenic tumors (OTs) in a Brazilian population and to compare this data with previous reports.

Methods: We reviewed the achieves of 19 123 specimens from oral pathology laboratory of Universidade Federal de Minas Gerais, from 1954 to 2004. Using the criteria of histologic typification published by the World Health Organization in 1992, we classified the OTs.

In vitro effects of a chlorhexidine controlled delivery system.

The aim of this work was study the effect of the chlorhexidine : hydroxypropyl-beta-cyclodextrin (CLX : HP-beta-CD) inclusion compound (IC) on in vitro slabs of bovine dentine. The substantivity, antimicrobial activity, and morphological effect of this inclusion compound were evaluated. Cyclodextrin improves the physical-chemical and pharmacological properties of drugs.
